Deployment Guide 9Chapter 1Preparing for a WLAN DeploymentTo ensure a smooth WLAN deployment, you need to begin with a bit of planning. A straightforward review of your deployment plan before you begin will result in optimal results more quickly. The goals of this chapter are to assist you in assessing your readiness for WLAN implementation and to provide tips and tricks to resolve any issues that might arise in your environment. The chapter covers the following topics:•"Assessing Your Requirements" on page10•"Planning" on page10•"Upgrading from Existing Wi-Fi" on page10•"New WLAN Deployment" on page11•"Site Surveys" on page12•"Budgeting Wi-Fi: The Chicken and Egg Problem" on page13•"Bandwidth Assumptions for Wi-Fi" on page14•"Overcoming Physical Impediments" on page15•"Operational Considerations" on page18•"Preparing the Wired Network for Wireless" on page17•"Deploying with Confidence" on page18Although this guide assumes an understanding of corporate data networking, previous experience with LAN configuration and deployment, and some basic Wi-Fi understanding, the chapter concludes with a section that provides additional support for the preceding sections: "Basic Wi-Fi Concepts" on page19.Note: This guide assumes an understanding of corporate data networking and past experience with LAN configuration and deployment. It also assumes some basic Wi-Fi understanding.

Chapter 1 Preparing for a WLAN Deployment10 AerohiveASSESSING YOUR REQUIREMENTSTo get started with your Aerohive WLAN installation, examine the basic requirements of your implementation. First, consider who your stakeholders are and take the time to fully understand their access requirements. Talk to department managers within your organization and make sure everyone has documented the full complement of potential users of your network. Check if the applications are standard employee applications or if there are other requirements, such as access for guests or consultants.Next, make a complete list of the application types that your Aerohive network will need to support. Begin your list with mission-critical applications, paying special attention to those that generate high levels of traffic and those requiring deterministic behavior. Identify applications with heavy data requirements and expected service levels.Demanding applications such as voice and video will require a higher density of access points. Many enterprises are investigating the potential of VoWLAN (Voice over WLAN) in the hopes of integrating mobile phones and IP-PBX systems. Doing so requires an evaluation of other data transmission types that can disrupt the quality of voice conversations. Because voice traffic is sensitive to network jitter and latency, an inadequate number of access points can degrade quality. To the user, excessive jitter and delay can cause clipped conversations or dropped calls. Additional quality and reliability issues might arise when transmitting video, such as for training video or surveillance operations, because of the sheer size of the data stream.Other applications such as network backup and file transfers can also have an impact on the network. Therefore, take into account any bandwidth-intensive applications if you expect your mobile workforce to be accessing the WLAN while these applications or services are occurring.Considering the above issues will result in a more informed—and therefore more successful—deployment plan.PLANNINGThis section reviews the fundamental elements for planning your WLAN deployment. This includes conducting a site survey, both for an upgrade from an existing WLAN and for a completely fresh—or greenfield—deployment.Upgrading from Existing Wi-FiIf you are upgrading to Aerohive from an existing WLAN, you already have plenty of data about how your current network is performing. This information can lead to more informed decisions about your new implementation.To begin, perform a quick site survey with the existing access points in place. If they are less than three years old and support 802.11g, their coverage and capacity should be equivalent or slightly lower than the Aerohive 802.11g radio. If the coverage is correct and has the appropriate density for your deployment, then you simply need to replace one set of access points with a new set of HiveAPs. However, this scenario is rare because network upgrades are usually done to improve capacity and to augment the existing layout with a denser deployment of access points.Be sure to take note whether your existing network uses "fat" or "thin" APs (access points). A "fat" AP is an autonomous or standalone access point, which contains the intelligence and capability to connect to any Ethernet switch. With a "thin" AP, most of the intelligence has been removed and replaced in a centralized WAN controller. A fat upgrade to Aerohive HiveAPs is very natural. Generally, with fat APs you simply need to unplug the existing ones and plug in the new HiveAPs and provision them. With this approach, you can maintain or enhance all existing VLANs and security policies. This is a huge advantage over migrating from fat AP to controller-based solutions because you typically need to re-architect the network.

Deployment Guide 11 PLANNINGUpgrading from a thin AP solution is also easy. However, because a thin AP makes use of an overlay tunneled network, you sometimes have to add a local VLAN for access or use tunnels to replicate the overlay network. However, because using VLANs rather than tunnels provides significant performance and scalability advantages, that is clearly the recommended path.New WLAN DeploymentIn a new—or greenfield—WLAN deployment, you do not have the benefit of an existing network for testing and analysis, which makes your job a bit more difficult. In this case, the following key questions are critical to the proper design of your WLAN:•How many users will need wireless service and what applications will they use?Determining the scope of your WLAN deployment will have a major impact on capacity and coverage. Will only certain groups within the organization have WLAN access, or will it be rolled out across the enterprise? Will you provide guest access to visitors, consultants, and contractors? Most WLANs support just data applications, but many organizations are considering adding voice services. Voice support raises other design considerations that drive the need for denser deployments of access points and different QoS (Quality of Service) settings.•Are there any known major sources of interference?For example, is there a nearby cafeteria with microwave ovens? Commercial-grade microwaves are a particularly bad source of interference. Is there a wireless telephone or video surveillance system not using Wi-Fi? Is there a radar installation nearby? If you cannot find the answer to these questions easily, consider employing a spectrum analysis product, such as the AirMagnet Spectrum Analyzer.•Are building blueprints available?With blueprints, you can see the location of elevators, load-bearing walls, and other building characteristics that can impact signal quality. Different materials, such as concrete walls, brick walls, cubicle walls, glass, and elevator shafts impact signal quality differently. You can often load these blueprints into a planning or site survey tool to make the process easier.•What devices need to access the WLAN?Determine and document the full complement of devices that people will use to access the WLAN. The performance requirements of the WLAN will depend on both the applications and the capabilities of the client devices. For example, design engineers, architects, and doctors tend to work with bandwidth-hungry applications, so you might need to provide greater capacity. Conversely, if it is a warehouse with a low client density of mostly barcode scanners, a lower access point density might be suitable. Finally it is important to consider voice, or the future use of voice. If some or all people will use VoWLAN (Voice over WLAN) devices, that can affect how many users each access point can accommodate.Note: For some access point deployment guidelines, see "Bandwidth Assumptions for Wi-Fi" on page14.

Chapter 1 Preparing for a WLAN Deployment12 AerohiveSite SurveysOne of the first questions IT managers ask when they are preparing for a WLAN deployment is whether or not a site survey should be performed. In a site survey, the administrator walks around the facility with a site survey tool to measure the RF (radio frequency) coverage of a test access point or the existing WLAN infrastructure.Whether or not you decide to do a site survey for your enterprise depends on the cost of the survey and the complexity of the environment. The three ways to deploy a wireless network—with and without a site survey—are explained below:•Predeployment SurveyThe safest approach is to perform a site survey before deployment to determine the best locations for the access points. Typically, site survey professionals temporarily place access points in different locations, take measurements, and adjust their settings and locations as necessary. After they complete the survey, they install the access points, and then perform another site survey to confirm that the goals have been achieved. This method is clearly the most reliable way to deploy a wireless network; however, it can be expensive, time consuming, and impractical if an enterprise has many sites.•Deploy and CheckIn this scenario, an initial site survey is not performed. Instead, wireless administrators make educated guesses on the best locations for the access points or they use a planning tool to determine the locations more reliably. After deploying the access points, the administrators do a quick site survey. If they need to provide greater coverage, they deploy additional access points. If there are areas where access points are interfering with each other, they then relocate one or more of them. With the Aerohive cooperative RF control, HiveAPs automatically adjust their channel and power to compensate for coverage gaps and areas of interference.The deploy-and-check approach is often much cheaper and faster than doing a predeployment site survey. The risk is that you might have to move some access points and CAT5 (Category 5) Ethernet cables if you do not plan properly. Aerohive provides a huge competitive advantage in the deploy-and-check approach, thanks to its flexible mesh networking capability. An administrator can deploy with mesh (before running wires) and check the performance in several layouts, determine the best layout, and then run the wires to their final location.•Deploy without SurveyWhile it is usually advisable to do a site survey, there are many situations in which it is not feasible or even necessary. If the location is sufficiently small—for example, a deployment of only three or fewer access points—site surveys have limited value because there is virtually no opportunity for interference. If there are numerous remote locations, a site survey might be impractical because of the cost of traveling to each site. In these locations, you can use a slightly denser deployment to ensure appropriate coverage and capacity. With Aerohive Cooperative RF control, HiveAPs automatically adjust their radio power levels to ensure that there is minimal overlap from interfering channels. Usually the cost of extra access points is offset by the cost saved by not doing a site survey in a remote location.

Deployment Guide 13 PLANNINGBudgeting Wi-Fi: The Chicken and Egg ProblemThe hardware cost of a Wi-Fi solution is generally driven by the number of access points needed, and an Aerohive network is no exception. Unfortunately, a traditional challenge of budgeting for Wi-Fi is that it is difficult to know how many access points to plan for until you have deployed and measured them. There are methods of doing site surveys before a deployment to answer these questions. While doing so is often worthwhile, you might just need a general idea of what you would need to budget. Fortunately there are some simple guidelines that you can use to figure out how many access points you need, including the number of access points per square foot, the number of clients per access point, and the distance between access points.•Access Points per Square FootThe simplest and most common way of budgeting access points is per square foot. You simply take the square footage of a building and divide it by some number. The most common metric used today is one access point for every 4,000 to 5,000 square feet for standard offices with cubicles. However, if you need to support voice applications, you need a higher concentration of access points. In this case, the recommended formula is one access point for every 3,000 square feet, or even as low as one access point for every 2,000 square feet. In the lightest weight convenience networks, it is possible to use fewer access points, and densities as low as one access point for every 10,000 to 15,000 square feet can be successful. Keep in mind that such a deployment often has dead spots and can only support very low client densities.•Number of Clients for Each Access PointAnother way to determine the number of access points needed is to consider the number of clients you want each access point to support. In a standard office environment, most enterprises plan to support an average of 5 to 15 clients per access point. While the specifications of most access points state that they can support up to about 120 clients, a significantly lower density is recommended to get an acceptable throughput for standard office applications. If you expect to support voice over Wi-Fi in the enterprise, account for those phones as well. With the addition of voice, the client density substantially increases, requiring you to plan for an average of 5 to 10 data clients and 5 to 10 voice clients for each access point. Remember that voice clients consume virtually zero bandwidth when they are not on a call. However, when they are on a call, it is imperative that the traffic goes through.•Distance Between Access PointsIn a standard office environment, it is a good idea to ensure that access points are between 30 and 100 feet from one another. A distance of 30 feet is needed in high-density environments and those with many walls separating access points. A distance of 100 feet is sufficient in low-density areas with plenty of open space.The three tips above can help determine how many access points to deploy in a given area. In general, the square footage estimate provides the best budgeting estimate, with client estimations and the distance between access points confirming the square footage calculations.As with all rules, there are exceptions. If certain locations in the network have a higher density of clients, such as conference rooms or lecture halls, a higher density of access points is required. Conversely if there are large open areas with few active clients, fewer access points are sufficient.Planning ToolsIf following general guidelines does not provide enough confidence or if the deployment environment is particularly challenging, you might consider using software planning tools like AirMagnet's Planner software. Such tools are useful in determining the placement of access points without performing a site survey.

Chapter 1 Preparing for a WLAN Deployment14 AerohiveAssociated Access Point CostsAfter you determine how many access points you need, it becomes simpler to determine the other costs involved with deploying Wi-Fi because most are driven by the quantity of access points. These costs include the following:•Installation and Wiring•CAT5 – CAT5 wiring is required for all HiveAPs acting as portals.1 One advantage of Aerohive Networks is that you can deploy HiveAPs in a mesh to avoid some of the wiring costs.•Power – Power lines are required for all HiveAPs acting as mesh points.2 Portals receive power through power lines or through Ethernet cables by using the Power-over-Ethernet (PoE) option.•Installation – HiveAPs can simply snap into standard dropped-ceiling environments. However, if the installation is in a warehouse or any environment without dropped ceilings, consider the installation costs.•Infrastructure: PoE SwitchesYou must cable every HiveAP acting as a portal to a switch port. For PoE, there are several considerations:•802.3af – The current PoE specification provides enough power for all 802.11a/b/g access points.•802.3at – The emerging PoE specification supports higher power devices like 802.11n access points. This standard is expected to be ratified at the end of 2008, so products are not yet available. •PoE injectors and midspans – These save money on switch upgrades by injecting power into standard Ethernet connections.•Site Survey and Debugging Software•For a sizable deployment, you probably will use site survey and debugging software. AirMagnet Laptop Analyzer and Survey are two products that pay for themselves very quickly. These products enable the validation of a deployment and allow you to troubleshoot client and access point issues. (For more information, see the section on "Operational Considerations" on page18.)•Professional Services•When deploying wireless LANs, professional services are often required perform site surveys.•Client Software•Depending on the deployment, users can use built-in Microsoft Windows, Linux and/or Macintosh client software (supplicants).•For better services and troubleshooting, consider a third-party supplicant such as Juniper Networks Odyssey Client.Bandwidth Assumptions for Wi-FiPeople frequently talk about how much coverage an access point provides; however, it is capacity—not coverage—that typically constrains an access point in an enterprise environment. The challenge is not how far the RF signal can travel (coverage), but how to deliver enough bandwidth to meet the demands of business applications (capacity). In other words, you might be able to cover an office of 50 people with one access point, but if all 50 people choose to access it at the same time, it will certainly become overloaded. Indeed, if you use the formulas provided in this paper, you should find the saturation of access points on your campus to be more than sufficient. Enterprise users are accustomed to speedy switched networks and expect similar performance from their wireless LAN connections. This is why documenting the size and type of applications that will rely on your WLAN is so critical to your planning. In short, if you plan for optimal capacity, complete coverage will follow automatically.1.A portal is a hive member that links one or more mesh points to the wired LAN.2.Mesh points are hive members that use a wireless backhaul connection to link through a portal to the wired LAN.

Deployment Guide 15 PLANNINGIn general, the way to increase capacity is to add more access points (within reason) and tune down the radio power to avoid interference. One reason for deploying a high capacity network is to create a WLAN for voice and data applications. In such a WLAN, everyone has a VoIP handset running wirelessly all the time.In general, the following table shows the standard densities for office deployments.Overcoming Physical ImpedimentsNot every potential deployment is a standard business campus.The following scenarios are a few that merit special consideration.•Open SpaceOpen spaces, such as a large foyer or an outdoor area, are very easy to cover with Wi-Fi because there are few impediments to propagation and fewer opportunities for multipath interference. In such spaces, Wi-Fi signals can propagate many hundreds of feet. This is good if you want to provide coverage for just a few users.You will run into challenges if there are many users and high capacity service goals. In these situations, it is important to tune down the RF to a minimal level. If you are using Aerohive cooperative RF control, the HiveAPs do this on their own automatically. Another trick is to take advantage of obstacles that block Wi-Fi. Look for trees or walls and put neighboring access points on either side of them. Doing so limits the interference of the two access points and allows for the installation of more access points with less interference.•Warehouse and RetailWarehouse and retail environments present many challenges. One of the largest challenges is that RF characteristics often change because of varying inventory levels and, in the case of retail, seasonal displays (such as tinsel or a stack of soda cans on an end cap). Additionally, metal shelves and high ceilings can be challenges to propagation. To resolve with these issues, it is wise to put at least one access point per aisle to ensure coverage for that aisle. This usually requires a higher density of access points than would otherwise be required.•Configuring AntennasAs anyone who has administered a WLAN system in the past knows, proper configuration of the access point antennas at the outset can save you lots of trouble. HiveAPs come standard with fixed omnidirectional antennas. You typically orient these antennas vertically, positioning the antennas on all HiveAPs in the same direction. Omnidirectional antennas create a coverage area that looks like a doughnut, broadcasting to the sides much more effectively than up or down (see Figure1 on page16). In general, this is good for most office environments because you have large flat floors. However, it can be a problem in environments with high ceilings.Office Requirements Expected Data Rate Using 802.11g for Each Access PointAccess Point DensityCoverage (low capacity) 12 Mbps to 24 Mbps 1 access point per 8000 square feetStandard office deployment36 Mbps 1 access point per 5000 square feetStandard office deployment with voice 54 Mbps 1 access point per 2000 – 3000 square feetNote: Data rate is not the same as TCP throughput. Because of various headers, inter-frame gaps, and session creation, real TCP throughput usually does not exceed 22 Mbps at data rates of 54 Mbps.

Chapter 1 Preparing for a WLAN Deployment16 AerohiveFigure 1 Omnidirectional Antenna Radiation PatternThe HiveAP can accommodate external antennas via coaxial jacks on its chassis (see "Antennas" on page28).The jack is a standard male RP-SMA connector. Various patch, directional, and omnidirectional antennas can be used to change the coverage pattern. The most common external antennas are patch antennas. These are directional antennas that provide coverage in a single direction. Most commonly they have a transmission pattern as shown in Figure2. Based on the gain, the signal will be wide (like the low gain antenna shown on top) or narrow and long (like the high gain antenna shown on the bottom). Note that the coverage patterns are not perfect for these antennas and that they often broadcast slightly in other directions than the primary one. These extra "lobes" can be seen in both of the patterns shown below.Figure 2 Directional Antenna PatternsThe following are some quick hints for deploying access points:•Standard sheetrock walls and dropped ceilings are the best locations for mounting access points.•When deploying WLANs in retail stores, doing a site survey at each store is likely to be impractical. It is more common to run detailed site surveys at a few locations and use the results to set up deployment guidelines for the remaining sites.•Be aware of metal-lined firewalls, steel pillars, and other metallic surfaces. RF signals can reflect off metal surfaces, which can cause unexpected coverage patterns. Also watch out for objects that can block or reflect signals, such as mirrors, plants, walls, steel doors, elevator shafts, and bathroom stalls.Ø·¹¸»® Ù¿·²Ô±©»® Ù¿·²øÞ·®¼Ž- Û§» Ê·»©÷Ð¿¬½¸ß²¬»²²¿-Ø·¹¸»® Ù¿·²

Chapter 1 Preparing for a WLAN Deployment18 AerohiveOPERATIONAL CONSIDERATIONSTo make your WLAN deployment process as smooth as possible, you should consider more than just the distribution and installation of access points. You should also consider how you will manage, optimize, and troubleshoot your WLAN after deployment.TuningApproach building an enterprise WLAN with the same life-cycle approach you would apply to a wired network. After you deploy the WLAN, revisit key network engineering processes to account for changes in the environment. Watch for access points that are overloaded or are under utilized, and check for potential dead spots. Furthermore, be aware that the likely points of failure can change as the environment changes. For example, a neighboring business might install access points that cause RF interference on your network. You should schedule and perform periodic walkthroughs to ensure that the design goals of the wireless network continue to be met. The Aerohive HiveManager provides quick views into how the network is behaving, which HiveAPs are the most heavily loaded, and which have the most clients.TroubleshootingSome of the most common issues that arise after deploying a new wireless network are RF interference, RADIUS issues, and desktop client issues. The first step in troubleshooting is to look at logs and use debug commands. Aerohive offers an extensive set of event monitoring and debug tools that you can use through HiveManager, the Aerohive network management system. For additional troubleshooting, particularly of clients or neighboring networks, Aerohive recommends two tools: Ethereal Warehouser (http://www.wireshark.org/) and AirMagnet Laptop Analyzer (http://www.airmagnet.com/products/laptop.htm).ManagementCurrent Wi-Fi networks typically span an entire company and have complex security policies. Fortunately, the HiveManager Network Management System makes it simple to manage large networks from a central location. It provides a single centralized management instance for the entire wireless network. While managed HiveAPs can operate without HiveManager, it simplifies the provisioning of global policy management and centralized configuration and monitoring. HiveManager lowers operating costs by speeding deployment, configuration, and monitoring of the wireless network.Managing faults and alarms is critical to maintaining uptime. You can view and manage events through HiveManager logging. Optionally, you can use a third-party tool such as HP OpenView.HiveManager makes it easy to monitor and troubleshoot HiveAPs within a WLAN infrastructure. HiveManager can import hierarchical map views that represent the physical location of the network, from the perspective of the entire world down to the floor level.Deploying with ConfidenceMoving a large enterprise—or even a small one—to a WLAN for the very first time need not be daunting. If you have moderate experience with LAN deployments of other types and you have taken time to get answers to the important questions that will affect the network data load, you have every prerequisite for success. The bottom line is to remember to take stock of your project before you begin to ward against unforeseen costs and performance bottlenecks. If you have considered the issues and guidelines presented here, you are not far away from a successful Aerohive WLAN deployment.

Deployment Guide 19 BASIC WI-FI CONCEPTSBASIC WI-FI CONCEPTSThe goal of this section is to provide some background on Wi-Fi propagation and how to lay out a wireless network. While RF (radio frequency) engineering is a rather complicated science, this section provides a simple overview on the basics of Wi-Fi propagation and channel layout that you need to be able to install an enterprise WLAN.The first thing to know is that Wi-Fi is forgiving. Wi-Fi tends to transmit a bit farther than you expect, and even in cases of interference, it tends to just work. This can be both a blessing and a curse. It is a blessing because people will likely have access to the network, and it is a curse because your overall performance might be suboptimal without obvious symptoms, like lack of connectivity. Understanding the basics presented in this section will help ensure a high performance layout.The first concept to understand is signal strength and how it relates to throughput. Radio power is measured in dBm (decibels relative to one milliwatt) where 0 dBm = 1 milliwatt, but decibels increase using a log10 math function. Rather than dusting off your old math books and pulling out your calculator, look at the dBm-to-milliwatt converter that appears below. Often in Wi-Fi, dBm and milliwatts (mW)—and microwatts ( W)—are used interchangeably. The following table converts between the two units of measurement.In RF, there is also a relative measurement that you can use to compare two numbers. This measurement is simply dB (without the "m"). To see how this concept is applied, consider how radio signal propagation changes over a distance and how it can be affected. Figure3 on page20 shows signal strength over distance as a curve that has the best signal strength closer to the access point. It also shows noise. In general, noise is considered to be low-level background RF signals that can interfere with a WLAN. This noise tends to be the garbled background RF that comes from everything from the sun and stars to man-made interfering devices like Bluetooth headsets. It is impossible to block out noise and it should not be attempted. This low level of background noise is called the "noise floor".dBm-to-milliwatt20 dBm = 100 mW 2 dBm = 1.6 mW15 dBm = 32 mW 1 dBm = 1.3 mW10 dBm = 10 mW 0 dBm = 1.0 mW 5 dBm = 3.2 mW -1 dBm = 794 µW4 dBm = 2.5 mW -5 dBm = 316 µW3 dBm = 2.0 mW -10 dBm = 100 µW

Chapter 1 Preparing for a WLAN Deployment20 AerohiveFigure 3 Path Loss in an Open SpaceWhen clients send a packet, the ratio of the signal-to-noise (SNR) level defines the quality of the link, which is directly related to the performance of the network. Based on the SNR, the client and AP negotiate a data rate in which to send the packet, so the higher the SNR the better. For good performance, the SNR should be greater than 20 dB, and for optimal performance it should be at least 25 dB.Signal strength not only diminishes over distance but it can also be affected by objects in the way (see Figure4).This can be a wall, a tree, or even a person. There is a fairly predictable dB drop through most objects that also decreases the SNR, thus decreasing the data rate. While this appears to be a bad thing, clever Wi-Fi installers use it to their advantage. It allows them to place more access points in a tighter spot by using pre-existing walls and other impediments to Wi-Fi propagation to keep them from interfering with each other.Figure 4 Path Loss through a WallÍ·¹²¿´ó¬±óÒ±·-»Î¿¬·±Ü·-¬¿²½»Ò±·-»Î»½»·ª»¼ Í·¹²¿´Í·¹²¿´ó¬±óÒ±·-»Î¿¬·±Ü·-¬¿²½»Ò±·-»Î»½»·ª»¼ Í·¹²¿´É¿´´

Deployment Guide 21 BASIC WI-FI CONCEPTSMicrowave ovens, wireless video cameras, Bluetooth headsets, and cordless phones can all interfere with Wi-Fi signals (see Figure5). Excess noise in an environment is often difficult to diagnose and can have a major negative impact on network performance. To discover noise sources, a spectrum analysis system is needed. AirMagnet provides an affordable spectrum analysis tool that operates in the 2.4 GHz and 5 GHz spectra.Figure 5 Path Loss with Noise (from Microwave)Now that you have a sense of how Wi-Fi performance changes over distance and with noise, look at some ways to perform channel assignment. If two access points are on the same channel right next to each other, they are forced to share the same spectrum. This means that they share the 54 Mbps available in 802.11a/g rather than each being capable of 54-Mbps speeds independently. This essentially halves the bandwidth for each access point. To manage this situation, make sure that neighboring APs are on different channels and that their power is adjusted so that it does not overlap that of other APs with the same channel.In the 2.4 GHz spectrum, there are 11 channels in the United States. However, a Wi-Fi signal consumes more than one channel. Consequently, there are only 3 non-overlapping channels: 1, 6, and 11. To achieve optimal performance, you need to design a channel layout pattern such as the one on the left in Figure6.Figure 6 Channel Layout PatternsÍ·¹²¿´ó¬±óÒ±·-»Î¿¬·±Ü·-¬¿²½»Ò±·-»Î»½»·ª»¼ Í·¹²¿´êìêðëîëêíêìììðêìêðëîëêíêìììðêìêðëîëêíêìììðêìêðëîëêíêìììðêìêðëîëêíêìììðêìêðëîëêíêìììðêìêðëîëêíêìììðéó¬±óï Ô¿§±«¬ Ð¿¬¬»®²ïïêïïïêïêïïïêïïïïïïê ïïïêêïïïêïïïïïêïíó¬±óï Ô¿§±«¬ Ð¿¬¬»®²ïïêï

Chapter 1 Preparing for a WLAN Deployment22 AerohiveDesigning a channel pattern is easier for the 5 GHz spectrum. Depending on the country and the device being used, there are between 4 and 14 channels available for Wi-Fi use. However, in most countries there are at least 8 to work with. To simplify the layout of more than 3 channels most use a 7-to-1 pattern, as is shown on the right in Figure6 on page21. This channel layout is much more flexible than the 3-channel system and allows for much better capacity over all channels.The last topic to cover is the concept of multipaths. When a client receives a transmission from an access point (or vice versa), the RF signal reaches the client first through a "direct path," but then shortly thereafter by the "indirect paths" reflected off other objects. The direct path combined with the indirect paths make up multipaths (see Figure7). RF signals can bounce off of almost anything—walls, people, plants, and so on—but they bounce the greatest off of metal. As the RF signals bounce about while propagating, one or more of the secondary paths can interfere with the primary path, causing the signal strength of the direct path to diminish. In doing so, multipath can greatly decrease signal to noise ratio.Figure 7 Multipath Radio WavesNote: There are alternative 2.4 GHz channel layouts, such as one for four channels using 1, 4, 8 and 11 and another using channels 1, 5, 9 to counter interference from microwaves, which tend to cause interference in the high end of the spectrum. Aerohive recommends alternative channel layouts only for the most challenging radio environments.Note: If you would like to learn more about how radio frequency propagation works or the details of 802.11, Wikipedia provides excellent background information under the entries "IEEE 802.11", "radio propagation", and "multipath". Additionally, spending a few hours with a site survey tool such as AirMagnet Surveyor and a few test APs can increase both your familiarity with Wi-Fi propagation and your confidence about how it behaves.Ð®·³¿®§ Ð¿¬¸Í»½±²¼¿®§ Ð¿¬¸Í»½±²¼¿®§ Ð¿¬¸

HiveAPs have the unique ability to self-organize and coordinate with each other, creating a distributed-control WLAN solution that offers greater mobility, security, quality of service, and radio control.This guide combines product information, installation instructions, and configuration examples for both the HiveAP and HiveManager platforms. This chapter covers the following topics relating to the HiveAP:•"HiveAP 20 Product Overview" on page24•"Ethernet and Console Ports" on page26•"Status LEDs" on page27•"Antennas" on page28•"Mounting the HiveAP 20" on page29•"Device, Power, and Environmental Specifications" on page31

Chapter 2 The HiveAP 20 ag Platform24 AerohiveHIVEAP 20 PRODUCT OVERVIEWThe HiveAP 20 ag is a multi-channel wireless AP (access point). It is compatible with IEEE 802.11b/g (2.4 GHz) and IEEE 802.11a (5 GHz) standards and supports a variety of Wi-Fi (wireless fidelity) security protocols, including WPA (Wi-Fi Protected Access) and WPA2.You can see the hardware components on the HiveAP in Figure1. Each component is described in Table1.Figure 1 HiveAP 20 Hardware ComponentsTable 1 HiveAP 20 Component DescriptionsComponent DescriptionFixed Dual-Band AntennasThe two fixed omnidirectional dipole antennas can operate at two radio frequencies: 2.4 GHz (for IEEE 802.11b/g) and 5 GHz (for IEEE 802.11a). For details, see "Antennas" on page28.Status LEDs The status LEDs convey operational states for system power, and the LAN, Access, and Mesh interfaces. For details, see "Status LEDs" on page27.802.11a RP-SMA Connector You can connect a detachable single-band antenna, such as the Pulse W1028 dipole antenna for the 5 GHz band, to the male 802.11a RP-SMA (reverse polarity-subminiature version A) connector. Note that doing so disables the adjacent fixed antenna.PowerConnectorMountingScrew10/100 Mbps Power-over-Ethernet PortResetButtonConsolePortDevice Lock SlotFixed Dual-Band AntennasConnectors for Detachable Single-Band AntennasStatus LEDsRP-SMA Connector for 802.11a Radio AntennaRP-SMA Connector for 802.11b/g Radio Antenna

Deployment Guide 25 HIVEAP 20 PRODUCT OVERVIEWPower Connector The 48-volt DC power connector (0.38 amps) is one of two methods through which you can power the HiveAP 20. To connect it to a 100 – 240-volt AC power source, use the AC/DC power adaptor that is available as an extra option. Because the HiveAP does not have an on/off switch, connecting it to a power source automatically powers on the device.Mounting Screw To mount the HiveAP 20 on a surface, attach the mounting plate that ships with the product to the HiveAP by inserting the two pins on the underside of the chassis into slots in the plate and tightening the mounting screw. For details, see "Mounting the HiveAP 20" on page29.10/100 Mbps PoE Port The 10/100-Mbps Ethernet port supports IEEE 802.3af PoE (Power over Ethernet) and receives RJ-45 connectors. The HiveAP can receive its power through an Ethernet connection to power sourcing equipment (PSE) that is 802.3af-compatible. (If you connect the HiveAP to a power source through the power connector and PoE port simultaneously, the device draws power through the power connector and automatically disables PoE.)The HiveAP can also connect to the wired network or to a wired device (such as a security camera) through this port. It is compatible with 10/100Base-T/TX and automatically negotiates half- and full-duplex connections with the connecting device. It is autosensing and adjusts to straight-through and cross-over Ethernet cables automatically. It also automatically adjusts for 802.3af Alternative A and B methods of PoE. For details, see "Ethernet and Console Ports" on page26.Reset Button The reset button allows you to reboot the device or reset the HiveAP to its factory default settings. Insert a paper clip, or something similar, into the Reset pinhole and press the reset button. To reboot the device, hold the button down between 1 and 5 seconds. To return the configuration to the factory default settings, hold it down for at least 5 seconds. After releasing the button, the Power LED goes dark, and then glows steady amber while the firmware loads and the system performs a self-test. After the software finishes loading, the Power LED glows steady green.To disable the reset button from resetting the configuration, enter this command: no reset-button reset-config-enable Pressing the button between 1 and 5 seconds will still reboot the HiveAP, but pressing it for more than 5 seconds will not reset its configuration.Console Port A male DB-9 serial port to which you can make a console connection using an RS-232 (or "null modem") cable. The management station from which you make a serial connection to the HiveAP must have a VT100 emulation program, such as Tera Term Pro© (a free terminal emulator) or Hilgraeve Hyperterminal® (provided with Windows® operating systems). The following are the serial connection settings: bits per second: 9600, data bits: 8, parity: none, stop bits: 1, flow control: none.Device Lock SlotYou can physically secure the HiveAP by attaching a lock and cable (such as a Kensington® notebook lock) to the device lock slot. After looping the cable around a secure object, insert the T-bar component of the lock into the slot on the HiveAP and turn the key to engage the lock mechanism.802.11b/g RP-SMA ConnectorYou can connect a detachable single-band antenna, such as the Pulse W1038 dipole antenna for the 2.4 GHz band, to the male 802.11b/g RP-SMA connector. Note that doing so disables the adjacent fixed antenna.Component Description

Chapter 2 The HiveAP 20 ag Platform26 AerohiveEthernet and Console PortsThere are two ports on the HiveAP 20: a 10/100Base-T/TX Ethernet port and a male DB-9 console port. Both ports use standard pin assignments.The pin assignments in the PoE (Power over Ethernet) Ethernet port follow the TIA/EIA-568-B standard (see Figure2). The PoE port accepts standard types of Ethernet cable—cat3, cat5, cat5e, or cat6—and can receive power over this cable from power sourcing equipment (PSE) that is 802.3af-compatible. Such equipment can be embedded in a switch or router, or it can come from purpose-built devices that inject power into the Ethernet line en route to the HiveAP. Because the PoE port has autosensing capabilities, the wiring termination in the Ethernet cable can be either straight-through or cross-over.Figure 2 PoE Wire Usage and Pin AssignmentsPin T568A Wire Color1White/Green2Green3White/Orange4Blue5White/Blue6Orange7White/Brown8Brown(View of the PoE port on the HiveAP)1 8Pin NumbersPin T568B Wire Color1White/Orange2Orange3White/Green4Blue5White/Blue6Green7White/Brown8BrownT568A-Terminated Ethernet Cable with an RJ-45 Connector802.3af Alternative A(Data and Power on the Same Wires)802.3af Alternative B(Data and Power on Separate Wires)Pin Data Signal MDI MDI-X MDI or MDI-X1Transmit +DC+DC–– – –2Transmit -DC+DC–– – –3Receive +DC–DC+ – – –4(unused) – – –– – –DC+5(unused) – – –– – –DC+6Receive -DC– DC+ – – –7(unused) – – –– – –DC–8(unused) – – –– – –DC–MDI = Medium dependent interface for straight-through connectionsMDI-X = Medium dependent interface for cross-over (X) connectionsThe PoE port is auto-sensing and can automatically adjust to transmit and receive data over straight-through or cross-over Ethernetconnections. Likewise, it can automatically adjust to 802.3af Alternative A and B power delivery methods. Furthermore, when theAlternative A method is used, the PoE port automatically allows for polarity reversals depending on its role as either MDI or MDI-X.T568B -terminated Ethernet Cable with an RJ-45 ConnectorT568A and T568B are two standard wiring termination schemes. Note that the only difference between them is that the white/green + solid green pair of wires and the white/orange + solid orange pair are reversed.For straight-through Ethernet cables—using either the T568A or T568B standard—the eight wires terminate at the same pins on each end.For cross-over Ethernet cables, the wires terminate at one end according to the T568A standard and at the other according to T568B.

Deployment Guide 27 HIVEAP 20 PRODUCT OVERVIEWThe pin assignments in the male DB-9 console port follow the EIA (Electronic Industries Alliance) RS-232 standard. To make a serial connection between your management system and the console port on the HiveAP, you can use a null modem serial cable, use another serial cable that complies with the RS-232 standard, or refer to the pin-to-signal mapping shown in Figure3 to make your own serial cable. Connect one end of the cable to the console port on the HiveAP and the other end to the serial (or COM) port on your management system. The management system must have a VT100 terminal emulation program, such as Tera Term Pro© (a free terminal emulator) or Hilgraeve Hyperterminal® (provided with Windows® operating systems).Figure 3 Console Port Pin AssignmentsStatus LEDsThe four status LEDs on the top of the HiveAP 20 indicate various states of activity through their color (dark, green, amber) and illumination patterns (steady glow or blinking).

$Chapter 2 The HiveAP 20 ag Platform28 AerohiveAntennasThe HiveAP 20 includes two fixed dual-band antennas with 3-dBi gains. These antennas are omnidirectional, providing fairly equal coverage in all directions in a toroidal (donut-shaped) pattern around each antenna. When the antennas are vertically positioned, coverage expands primarily on the horizontal plane, extending horizontally much more than vertically. See Figure4, which shows the toroidal pattern emanating from a single vertically positioned antenna. To change coverage to be more vertical than horizontal, position the antennas horizontally. You can also resize the area of coverage by increasing or decreasing the signal strength. Figure 4 Omnidirectional Radiation PatternThe pair of fixed dual-band antennas operate concurrently in two different frequency ranges: 2.4GHz (IEEE 802.11b/g) and 5 GHz (IEEE 802.11a). Using two different frequency ranges reduces the probability of interference that can occur when numerous channels operate within the same range. Conceptually, the relationship of antennas and radios is shown in Figure5.Figure 5 Antennas and Radios\After connecting an external antenna to an RP-SMA connector, you must enter the following command to move the appropriate interface from the adjacent fixed antenna to the external antenna:interface interface radio antenna externalNote: To show the shape of radiation more clearly, this illustration depicts the coverage provided by only one active antenna and is not drawn to scale.The omnidirectional antennas radiate equally in all directions, forming a toroidal pattern.HiveAPRadio 1RF 802.11b/g2.4 GHzRadio 2RF 802.11a5 GHzAntennaSwitch 1Antenna Switch 2RP-SMA Connectors802.11a/b/g Dual-Band FixedAntenna802.11a/b/g Dual-Band FixedAntennaCut-away view of the HiveAP to show the relationship of the antennas and the two internal radios.$

Deployment Guide 29 MOUNTINGTHE HIVEAP 20The wifi0 interface links to radio 1 (frequency range = 2.4 GHz for IEEE 802.11b/g), and the wifi1 interface links to radio2 (frequency range = 5 GHz for IEEE 802.11a). These interface-to-radio relationships are permanent. However, the interface-to-antenna relationships can be shifted. In other words, you can change which antenna—fixed or external—the wifi0 and wifi1 interfaces use. For example, to link the wifi0 interface to an external antenna connected to the 802.11b/g RP-SMA connector (for radio 1), enter the following command:interface wifi0 radio antenna external If you do not enter this command, the wifi0 interface and all its subinterfaces (wifi0.1, wifi0.2, wifi0.3, and wifi0.4) continue to use both fixed antennas.To unlink the wifi0 interface from the external antenna and return it to the fixed antennas, enter this command:interface wifi0 radio antenna internalMOUNTINGTHE HIVEAP 20Using the mounting plate and track clip, you can mount the HiveAP 20 to the tracks of a dropped ceiling grid. Using just the mounting plate, you can mount the HiveAP to any surface that can support its weight (1.5 lb., 0.68 kg).Ceiling MountTo mount the HiveAP 20 to a track in a dropped ceiling, you need the mounting plate, track clip, and two cross-head screws that ship with the track clip. You also need a cross-head screw driver and—most likely—a ladder.Attach the track clip to the mounting plate, and then attach the clip-plate combination to the HiveAP 20, as shown in Figure6.Figure 6 Attaching the HiveAP 20 to the Mounting Plate and Track ClipNote: After entering the above command, the radio to which you attached the external antenna uses the external antenna and the fixed antenna on the opposite side of the HiveAP. Attaching an external antenna only disconnects the adjacent fixed antenna.

The power source must have a readily accessible service disconnect switch incorporated into the fixed wiring installation so that you have the ability to turn the power on and off.

Deployment Guide 35 HIVEAP 28 PRODUCT OVERVIEWEthernet PortThe HiveAP 28 has a 10/100Base-T/TX PoE (Power over Ethernet) port. Its pin assignments follow the TIA/EIA-568-B standard (see Figure2 on page26). The PoE port accepts standard types of Ethernet cable—cat3, cat5, cat5e, or cat6—and can receive power over this cable from power sourcing equipment (PSE) that is 802.3af-compatible. Such equipment can be embedded in a switch or router, or it can come from purpose-built devices that inject power into the Ethernet line en route to the HiveAP. Because the PoE port has autosensing capabilities, the wiring termination in the Ethernet cable can be either straight-through or cross-over (MDI/MDI-X). For outdoor deployments use weatherproofed shielded twisted pair (STP) Ethernet cables.To ensure a waterproof seal for the Ethernet connection, use the RJ-45 connector assembly, which comes in three parts: a compression nut, end cap, and gasket.Figure 2 Connecting the Ethernet Cable1.Insert one end of the Ethernet cable through the waterproof RJ-45 connector assembly and plug the cable into the Ethernet port.2.Tighten the compression nut by twisting it clockwise into the Ethernet port housing on the chassis.3.Tighten the end cap by twisting it clockwise onto the compression nut and tighten until the rubber gasket emerges and wrap itself around the Ethernet cable.The Ethernet connection is now sealed and waterproof.10/100 Mbps PoE Port The 10/100-Mbps Ethernet port supports IEEE 802.3af PoE (Power over Ethernet) and receives RJ-45 connectors. The HiveAP can receive its power through an Ethernet connection to PSE (power sourcing equipment) that is 802.3af-compatible. (If you connect the HiveAP to a power source through the power connector and PoE port simultaneously, the device draws power through the power connector and automatically disables PoE.)The HiveAP 28 can also connect to the wired network or to a wired device (such as a security camera) through this port. It is compatible with 10/100Base-T/TX and automatically negotiates half- and full-duplex connections with the connecting device. It is autosensing and adjusts to straight-through and cross-over Ethernet cables automatically (MDI/MDI-X). It also automatically adjusts for 802.3af Alternative A and B methods of PoE.

Chapter 3 The HiveAP 28 Outdoor Platform36 Aerohive4.Connect the other end of the Ethernet cable to PSE (power sourcing equipment), such as a power injector, if the HiveAP 28 receives power through PoE, or directly to a network device, such as a switch, if it receives power through a power cord.If the Ethernet cable connects the HiveAP to another device that is indoors, you must install appropriate lightning protection at the point before it enters the building. Failing to do so might cause damage to the equipment as well as serious injury or death.Power ConnectorThe HiveAP 28 can receive power through an Ethernet cable using PoE or through a power cord. Aerohive recommends using either PoE or wiring the power cord directly to a 100 – 240-volt AC power source. Only plug the power cord into an electric outlet when configuring the device before deployment or when testing it in the lab.To connect the power cord to the HiveAP 28:1.Align the slot in the power cord plug with the small tab at the top of the three-pin power connector, and slide the plug firmly over the pins until it is fully seated in the power connector.2.Slide the cover over the connector and tighten it by turning the cover clockwise.3.Install a lightning protector between the HiveAP 28 and its power source.4.When possible, run the cord through a conduit to protect it from the elements. Where the cord is exposed, allow enough slack in it to create a drip loop. Leaving some slack in the cord lets water run away from the connections at each end. Use only a weatherproof power cord, such as the cord that ships with the HiveAP 28.5.Strip the other end of the power cord and wire it directly to a power source, such as a junction box that has a service disconnect switch that you can use to turn the power on and off. Also, because the HiveAP 28 does not have short-circuit (over current) protection built into it, it relies on the protection provided by the power source to which you connect it. Ensure that the protective device, such as a circuit breaker, is not rated greater than 15A. Furthermore, if you need to install the HiveAP 28 in a wet or damp location, the AC branch circuit that is powering it must be provided with ground fault protection (GFCI), as required by Article 210 of the National Electrical Code (NEC).Note: To prevent damage to the HiveAP 28 or power injector when using PoE to provide power, connect the Ethernet cable from the power injector to the HiveAP 28, and connect the injector to a power jack before applying power.Note: When the HiveAP acts as a mesh point and does not use the Ethernet port, cover the Ethernet port with a connector cap to prevent water intrusion and possible safety hazards.Note: When the HiveAP receives power through PoE, cover the power connector with a connector cap to prevent water intrusion and possible safety hazards.Note: The HiveAP 28 must be grounded. Do not operate it unless there is a suitably installed ground conductor. Contact the appropriate electrical inspection authority or an electrician if you are uncertain that suitable grounding is available.

$Deployment Guide 37 HIVEAP 28 PRODUCT OVERVIEWAntennasThe HiveAP 28 includes two detachable single-band antennas with 8dBi gains (802.11b/g) and two detachable single-band antennas with 10dBi gains (802.11a). These antennas are omnidirectional, providing fairly equal coverage in all directions in a toroidal (donut-shaped) pattern around each antenna. When the antennas are vertically positioned, coverage expands primarily on the horizontal plane, extending horizontally much more than vertically. See Figure3, which shows the toroidal pattern emanating from a single vertically positioned antenna. Note that when high gain antennas are added, the torus shape becomes somewhat elongated or compressed. If the HiveAP 28 is mounted higher than 20 feet the center of the torus curves inward so that the connection quality, directly underneath the center of the HiveAP 28, becomes compromised.To change coverage to be more vertical than horizontal, position the HiveAP so that the antennas are on a horizontal plane. You can also resize the area of coverage by increasing or decreasing the signal strength. Figure 3 Omnidirectional Radiation PatternThe pairs of antennas operate concurrently in two different frequency ranges: 2.4GHz (IEEE 802.11b/g) and 5 GHz (IEEE 802.11a). Using two different frequency ranges reduces the probability of interference that can occur when numerous channels operate within the same range. Conceptually, the relationship of antennas and radios is shown in Figure4. (For information about attaching the antennas to the HiveAP 28, see "Attaching Antennas" on page42.)Figure 4 Antennas and Radios\Note: The HiveAP 20 uses interface interface radio antenna external command to enable an external antenna attached to it. Entering this command on the HiveAP 28 disables the antenna on the opposite side of the device from the radio to which the interface is linked and results in a loss of diversity.Note: To show the shape of radiation more clearly, this illustration depicts the coverage provided by only one active antenna and is not drawn to scale.The omnidirectional antennas radiate equally in all directions, forming a toroidal pattern.HiveAPThe two 802.11b/g antennas link internally to Radio 1 and broadcast in the 2.4 GHz frequency range.802.11a Main Antenna 802.11b/g Main Antenna802.11b/g Auxiliary Antenna 802.11a Auxiliary AntennaThe two 802.11a antennas link internally to Radio 2 and broadcast in the 5 GHz frequency range.Radio 1RF 802.11b/g2.4 GHzRadio 2RF 802.11a5 GHz$

Chapter 3 The HiveAP 28 Outdoor Platform38 AerohiveMOUNTINGTHE HIVEAP 28 AND ATTACHING ANTENNASUsing the mounting accessories (available separately) you can mount the HiveAP in various locations:•"Pole Mount" on page39 – Mount the HiveAP 28 on a pole such as a street light.•"Strand Mount" on page40 – Suspend the HiveAP 28 from a cable or phone line.•"Surface Mount" on page41 – Mount the HiveAP 28 on a flat surface such as a wall or beam.You can mount the HiveAP 28 in any of these locations as long as the object to which you mount it and the attaching screws can support its weight (9 lbs., 4.08 kg).After mounting the HiveAP 28, attach the antennas as explained in "Attaching Antennas" on page42.Before you mount the HiveAP 28 and attach antennas, read the following warnings and cautions:•To install the HiveAP 28, you must be a qualified installation professional, licensed or certified in accordance with local regulations.•Use lightning arrestors and ground both the HiveAP 28 and any separately mounted antennas.•Do not connect or disconnect antennas or cables from the HiveAP 28 during periods of lightning activity.•If you need to place the HiveAP 28 in an explosive environment, such as in an oil refinery, mine, or any place where there is flammable gas, it must first be encased in an ATEX enclosure.•To comply with RF (radio frequency) exposure limits, do not place antennas within 6.56 feet (2 meters) of people.•Do not locate antennas near overhead power lines or other electric light or power circuits, or where they can come into contact with such circuits. When installing antennas, take extreme care not to come into contact with these circuits, which might cause serious injury or death. For proper installation and grounding of the antenna, refer to national and local electrical codes: NFPA (National Fire Protection Association) 70, National Electrical Code Article 810 (U.S.); Canadian Electrical Code, Part I, CSA 22.1 and Section 54 (Canada); and if local or national electrical codes are not available, refer to IEC (International Electrotechnical Commission) 364, Part 1 through 7 (other countries).•To prevent damage, avoid over-tightening the connectors, nuts, and screws used to mount the HiveAP 28 and antennas.

Deployment Guide 39 MOUNTINGTHE HIVEAP 28 AND ATTACHING ANTENNASPole MountTo mount the HiveAP 28 to a pole with a 1.5-inch diameter, you need two sets of the L-shaped brackets, two 2" U-bolts, saddle clamps, and the nuts, bolts, and washers shown in Figure5. You also need a wrench to tighten the nuts and bolts securely.Figure 5 Attaching the HiveAP 28 to a Pole1.Align two of the holes in the shorter end of the bracket with two of the holes in the HiveAP, insert the two bolts through the washers and bracket, and screw them into the holes in the HiveAP 28 chassis, using a wrench to tighten the bolts so that the bracket is securely attached.2.Holding a saddle clamp against the inside of the long end of one of the L-shaped brackets, slip a U-bolt around the pole and thread it through the two holes in the saddle clamp and L-shaped bracket.3.Thread a split washer and 5/16-18 nut to each end of the U-bolt, and tighten them with a wrench to secure the U-bolt firmly to the pole.Note: Repeat this step to attach the other bracket to the HiveAP. However, this time, place the long end of the bracket in the opposite direction of the first one for better stability. For example, if you attached the first bracket with its long end positioned toward the outside edge of the device, install this second bracket with the long end of the bracket toward the middle.Note: One of the holes in the bracket is arc-shaped so that you can adjust the angle of the mounted device if necessary.Note: Repeat steps 2 and 3 to attach the other U-bolt and saddle clamp to the remaining L-shaped bracket and secure the HiveAP 28 to the pole.Í¿¼¼´» Ý´¿³°Ê»®¬·½¿´ Ð±´» øïòëŒ ¼·¿³»¬»®÷ îŒ ËóÞ±´¬Í°´·¬ É¿-¸»®-ëñïêóïè Ò«¬-ÔóÍ¸¿°»¼ Þ®¿½µ»¬ïñìóîð Þ±´¬-¿²¼Í°´·¬ É¿-¸»®-Þ·®¼Ž-óÛ§» Ê·»©Í·¼» ª·»© ±º ¬¸» Ø·ª»ßÐ îè ³±«²¬»¼ ¬± ¿ -¬®»»¬ ´·¹¸¬Note: For clarity, only one post mounting set is shown in the illustration.

Chapter 3 The HiveAP 28 Outdoor Platform40 AerohiveStrand MountThe HiveAP 28 outdoor platform can also be mounted on a cable or strand of wire as shown in Figure6. When mounted on a wire strand, use 90-degree N type adapters (not included) to orient the antennas vertically. If you do not use the adapters and orient the antennas horizontally, the area covered will be far less. Figure 6 Clamping the HiveAP 28 to a Wire StrandTo mount the HiveAP 28 on a wire or strand, you need a wrench and two 1/4-20 bolts, split washers, strand clamps, and 90-degree type N adapters. In the following instructions, you use only the 2.4 GHz antennas.1.Position the HiveAP 28 so that its long side (with three holes at each end) is underneath a cable or wire strand running lengthwise along the upper side of the chassis (for the proper orientation, see the inset in Figure6).2.Place the strand clamp over the wire and use the 1/4-20 bolt and split washer to secure the strand between the clamp and chassis.3.Attach the 90-degree type N adapters to the two 2.4 GHz antenna connectors and then attach the antennas to the adapters so that the antennas face downward.

Deployment Guide 41 MOUNTINGTHE HIVEAP 28 AND ATTACHING ANTENNASSurface MountYou can use the mounting plate to attach the HiveAP 28 to any surface that supports its weight (9 lbs., 4.08 kg), and to which you can screw or nail the plate. First, mount the plate to the HiveAP 28, and then attach the plate to the surface, as shown in Figure7. Note that the screw heads that you attach to the wall or surface must be small enough for the keyholes on the mounting plate to slip over them.Figure 7 Mounting the HiveAP 28 on a WallTo mount the HiveAP 28 to a surface like a wall, you need two mounting plates, four 1/4-20 x 1/2" flat head screws, four screws (no bigger than 5/16"), and a screw driver: 1.Align the ridged edge of one of the mounting plates with two of the holes located on the underside of the HiveAP 28, and use two 1/4-20 x 1/2" flat head screws to secure the plate against the HiveAP 28. Then attach the other mounting plate to the HiveAP 28 in the same way.2.Attach four 5/16" screws to a wall or beam. They must be 8 1/8" (206 mm) apart vertically and 7 7/8" (200 mm) apart horizontally to accommodate the keyholes on the mounting plates.3.Guide the keyholes over the screws fastened to the wall and push downward after the screw heads have cleared the keyholes.Note: Because the metal in a wall can degrade the radio signal pattern, Aerohive recommends using sector antennas instead of omnidirectional antennas when mounting the device on a wall.ë ÙØ¦ îòì ÙØ¦é éñèŒîðð ³³Ì±° ±º É¿´´ë ÙØ¦ îòì ÙØ¦Ó±«²¬·²¹ Ð´¿¬»ïñìóîð ¨ ïñîŒ Ú´¿¬ Ø»¿¼ Í½®»©-Þ·®¼Ž-óÛ§» Ê·»©Í·¼» ª·»© ±º ¬¸» Ø·ª»ßÐ îè ³±«²¬»¼ ±² ¿² »¨¬»®·±® ©¿´´Guide the screws fastened to the wall through the keyholes in the mounting plates.Attach four screws to a secure object such as a wall or beam.

You also need a second plate with another set of screws.

Chapter 3 The HiveAP 28 Outdoor Platform42 AerohiveAttaching AntennasYou can connect the antennas directly to the HiveAP 28 or mount them separately. Although connecting the antennas directly to the device typically provides better performance, in some cases the location of the HiveAP might not be a good location for the antennas; for example, if the HiveAP 28 is mounted on a reinforced concrete wall that interferes with radio coverage. In such cases, mounting the antennas separately in a more open location can improve coverage; however, bear in mind that cables introduce loss into the overall signal strength and that the longer the cable connecting the antennas to the HiveAP 28, the greater the loss will be.Connecting Antennas Directly to the HiveAP 28The two 2.4 GHz and two 5 GHz antennas that ship with the HiveAP 28 have male Type N connectors that you can connect directly to the female Type N antenna connectors on the HiveAP 28. You can also use self-amalgamating PTFE (polytetrafluoroethylene) tape, which is available separately from Aerohive, to create a waterproof seal at the points of attachment.To attach the antennas: 1.Remove the antenna connector covers from the HiveAP 28 (leave the covers on any connectors that you do not plan to use), and make sure that the surface of the connectors on the HiveAP 28 and the connectors on the antennas are clean.2.If you are using PTFE tape, wrap the tape around the threads on the HiveAP 28 antenna connectors as follows:2.1.Starting at one end of the threads on one of the connectors, stretch the tape and wrap it in half-lap layers until you cover the threads completely.2.2.Wrap the tape in the opposite direction to bring it back onto itself for one full wrap.2.3.Place one thumb on the tape at the point of termination and stretch the tape until it breaks.2.4.Repeat the preceding steps to cover all the connectors to which you will attach antennas.3.Connect the 2.4 GHz antennas to the 2.4 GHz antenna connectors. (To tighten an antenna, turn the antenna base cap—the textured metal band that encloses the connector—clockwise over the tape-covered threads of the HiveAP antenna connector.)Their connections are now sealed and waterproof.4.Repeat the preceding steps to connect the 5 GHz antennas.Mounting Antennas SeparatelyIn addition to connecting antennas directly to the HiveAP 28, you can also mount them separately and run a cable between the antennas and the device. Use either male-to-female cables with Type N connectors or use male-to-male or female-to-female cables with cable gender changers. (The antennas have male Type N connectors and the HiveAP 28 has female Type N connectors.)Note: Cover any unused antenna connectors with a connector cap to prevent water intrusion and possible safety hazards.Note: Using cables to mount antennas separately causes some signal loss and using a cable gender changer can cause even more. The amount of loss varies from product to product, so refer to the documentation accompanying the cables and gender changer you use for information. To minimize loss, Aerohive recommends using LMR400 cables and using the shortest cables possible.

Deployment Guide 43 MOUNTINGTHE HIVEAP 28 AND ATTACHING ANTENNASYou can mount antennas at the top of a pole as shown in Figure8 and Figure9, or to a flat surface. If you must mount the antenna lower on a pole, the pole must be nonmetallic—such as one made from a hard plastic like PVC (polyvinyl chloride)—so that it does not distort the signal. Aerohive recommends that antennas be installed away from power lines and obstructions that can interfere with radio coverage.For each antenna that you mount, you need an attachment clamp, a 1 3/8" bolt and nut, a V-bolt, two washers and two nuts, a hose clamp, and two wrenches.Figure 8 Securing an Antenna to an Attachment Clamp1.Insert the 1 3/8" bolt through the attachment clamp and screw a nut loosely onto its end.2.Place the antenna base cap inside the attachment clamp.3.Using a pair of wrenches, tighten the nut to the bolt until the clamp grips the base cap firmly.Figure 9 Mounting an Antenna to a Pole4.To mount the antenna on a nonmetallic pole, place the attachment clamp against the pole, thread the V-bolt through the holes on the attachment, the washers, and nuts, and use the wrenches to tighten the nuts to the bolt. (Optional) For added stability, fasten the top of the antenna to the pole with the hose clamp.To mount the antenna directly to a flat surface, run bolts or screws (not included) through the two holes in the attachment clamp, and fasten them firmly to the surface.ß¬¬¿½¸³»²¬ Ý´¿³°Þ¿-» Ý¿°ß²¬»²²¿ï íñèŒ Þ±´¬ Ò«¬Use one wrench to hold the nut in place and the other to tighten the bolt.Insert the antenna into the clamp until it grips the base cap.Insert the bolt through the attachment clamp and hold it in place with the nut.

Chapter 3 The HiveAP 28 Outdoor Platform44 Aerohive5.Make sure that all the antenna and cable connectors are clean. If you are using PTFE tape, wrap the tape around the threads on the HiveAP 28 antenna connectors as explained in "Connecting Antennas Directly to the HiveAP 28" on page42.6.Assuming that you are using male-to-female cables, connect the female Type N connector on the cables to the male connectors on the antennas.7.Connect the male Type N connectors on the cables to the female antenna connectors on the HiveAP 28.DEVICE, POWER,AND ENVIRONMENTAL SPECIFICATIONSUnderstanding the range of specifications for the HiveAP is necessary for optimal deployment and device operation.

Deployment Guide 47 HIVEAP 340 PRODUCT OVERVIEW10/100/1000 Mbps PoE Ports The two 10/100/1000-Mbps Ethernet ports—ETH0 and ETH1—support IEEE 802.3af and 802.3at PoE (Power over Ethernet) and receive RJ-45 connectors. The HiveAP can receive power through one or both Ethernet connections from power sourcing equipment (PSE) that is compatible with the 802.3af standard and forthcoming 802.at standard. (If you connect the HiveAP to a power source through the power connector and PoE ports simultaneously, the device draws power through the power connector and automatically disables PoE.)You can configure ETH0 and ETH1 as two individual Ethernet interfaces, combine them into an aggregate interface to increase throughput, or combine them into a redundant interface to increase reliability. You can connect the HiveAP 340 to a wired network or to a wired device (such as a security camera) through these ports using bridging. They are compatible with 10/100/1000Base-T/TX and automatically negotiate half- and full-duplex connections with the connecting device. They are autosensing and adjust to straight-through and cross-over Ethernet cables automatically. For details, see "Ethernet and Console Ports" on page48.Power Connector The 48-volt DC power connector (0.625 amps) is one of two methods through which you can power the HiveAP 340. To connect it to a 100 – 240-volt AC power source, use the AC/DC power adaptor that is available as an extra option. Because the HiveAP does not have an on/off switch, connecting it to a power source automatically powers on the device.Console Port You can access the CLI by making a serial connection to the RJ-45 console port. The management station from which you make a serial connection to the HiveAP must have a VT100 emulation program, such as Tera Term Pro© (a free terminal emulator) or Hilgraeve Hyperterminal® (provided with Windows® operating systems). The following are the serial connection settings: bits per second: 9600, data bits: 8, parity: none, stop bits: 1, flow control: none. For details, see "Ethernet and Console Ports" on page48.Reset Button The reset button allows you to reboot the device or reset the HiveAP to its factory default settings. Insert a paper clip, or something similar, into the Reset pinhole and press the reset button. To reboot the device, hold the button down between 1 and 5 seconds. To return the configuration to the factory default settings, hold it down for at least 5 seconds. After releasing the button, the Power LED goes dark as the system reboots. Then it pulses green while the firmware loads and the system performs a self-test. After the software finishes loading, the Power LED glows steady green.To disable the reset button from resetting the configuration, enter this command: no reset-button reset-config-enable Pressing the button between 1 and 5 seconds will still reboot the HiveAP, but pressing it for more than 5 seconds will not reset its configuration.Note: The rear surface of the HiveAP 340 is used for heat dissipation to reduce the internal temperature. Consequently, it can become hot, so use caution when handling it.Component Description

Chapter 4 The HiveAP 340 Platform48 AerohiveEthernet and Console PortsThere are three ports on the HiveAP 340: two RJ-45 10/100/1000Base-T/TX Ethernet ports and an RJ-45 console port.The pin assignments in the PoE (Power over Ethernet) Ethernet ports follow the TIA/EIA-568-B standard (see Figure2). The ports accept standard types of Ethernet cable—cat3, cat5, cat5e, or cat6—and can receive power over this cable from power sourcing equipment (PSE) that is 802.3af-compatible. If you use cat5, cat5e, or cat6 cables, the HiveAP 340 can also support 802.3at-compliant PSE. Such equipment can be embedded in a switch or router, or it can come from purpose-built devices that inject power into the Ethernet line en route to the HiveAP. Because the PoE ports have autosensing capabilities, the wiring termination in the Ethernet cable can be either straight-through or cross-over.Figure 2 PoE Wire Usage and Pin AssignmentsÛÌØðPin T568A Wire Color1White/Green2Green3White/Orange4Blue5White/Blue6Orange7White/Brown8Brown(View of the ETH0 PoE Port on the HiveAP 340)8 1Pin NumbersPin T568B Wire Color1White/Orange2Orange3White/Green4Blue5White/Blue6Green7White/Brown8BrownT568A-Terminated Ethernet Cable with an RJ-45 Connector802.3af Alternative A(Data and Power on the Same Wires)802.3af Alternative B(Data and Power on Separate Wires)802.3at Wiring OptionsPin Data Signal MDI MDI-X MDI or MDI-X 1 2 3 41Transmit +DC+DC–– – –DC1+DC1–DC1+DC1–2Transmit -DC+DC–– – –DC1+DC1–DC1+DC1–3Receive +DC–DC+ – – –DC1–DC1+DC1–DC1+4(unused) – – –– – –DC+ DC2+DC2+DC2–DC2–5(unused) – – –– – –DC+ DC2+DC2+DC2–DC2–6Receive -DC– DC+ – – –DC1–DC1+DC1–DC1+7(unused) – – –– – –DC–DC2–DC2–DC2+DC2+8(unused) – – –– – –DC–DC2–DC2–DC2+DC2+MDI = Medium dependent interface for straight-through connectionsMDI-X = Medium dependent interface for cross-over (X) connectionsThe PoE ports are auto-sensing and can automatically adjust to transmit and receive data over straight-through or cross-over Etherneconnections. Likewise, they can automatically adjust to 802.3af Alternative A and B power delivery methods. Furthermore, when theAlternative A method is used, the ports automatically allow for polarity reversals depending on their role as either MDI or MDI-X. In 802.3at, the 1/2 and 3/6 wire pairs connect to DC source 1 and 4/5 and 7/8 pairs to DC source 2 in PSE. Although the exact polarity depends on the PSE design, the HiveAP 340 Ethernet ports can support all possible options.T568B -terminated Ethernet Cable with an RJ-45 ConnectorT568A and T568B are two standard wiring termination schemes. Note that the only difference between them is that the white/green + solid green pair of wires and the white/orange + solid orange pair are reversed.For straight-through Ethernet cables—using either the T568A or T568B standard—the eight wires terminate at the same pins on each end.For cross-over Ethernet cables, the wires terminate at one end according to the T568A standard and at the other according to T568B.

Deployment Guide 49 HIVEAP 340 PRODUCT OVERVIEWSmart PoEThe HiveAP 340 applies the Aerohive concept of smart PoE to adjust power consumption as necessitated by varying levels of available power. If the HiveAP needs more power than is available, it first disables the ETH1 interface. If it still needs more power, it switches from 3x3 MIMO (Multiple In, Multiple Out) to 2x3 (see "MIMO" on page53). In rare cases when further power conservation is necessary, the HiveAP then reduces the speed on ETH0 from 10/100/1000 Mbps to 10/100 Mbps. Finally, in the event that there is a problem with the PoE switch or Ethernet cable, the HiveAP disables its wireless interfaces and returns its ETH0 and ETH1 interfaces to 10/100/1000 Mbps speeds. Through the application of smart PoE, the HiveAP 340 can make power usage adjustments so that it can continue functioning even when the available power level drops.Aggregate and Redundant InterfacesBy default ETH0 and ETH1 act as two individual Ethernet interfaces. When both interfaces are connected to the network and are in backhaul mode, the HiveAP transmits broadcast traffic only through ETH0. The HiveAP transmits broadcast traffic through ETH1 only when ETH0 does not have network connectivity. When both Ethernet interfaces are connected to the network and are in access mode, then the HiveAP transmits broadcast traffic through all the access interfaces: ETH0, ETH1, and all wireless subinterfaces in access mode.In addition to using ETH0 and ETH1 as individual interfaces, you can combine them into an aggregate interface (agg0) to increase throughput, or combine them into a redundant interface (red0) to increase reliability. The logical red0 and agg0 interfaces support all the settings that you can configure for Ethernet interfaces except those pertaining to physical link characteristics such as link speed. See the sections below for configuration information.Aggregate InterfaceYou can increase throughput onto the wired network by combining ETH0 and ETH1 into a single logically aggregated interface called "agg0". The aggregate interface effectively doubles the bandwidth that each physical interface has when used individually. In this configuration, both Ethernet ports actively forward traffic, the HiveAP applying an internal scheduling mechanism based on the source MAC address of each packet to send traffic through the aggregate member interfaces. To configure an aggregate interface, enter the following commands:interface eth0 bind agg0interface eth1 bind agg0In addition to configuring the HiveAP, you must also configure the connecting switch to support EtherChannel. For example, the following commands bind two physical Ethernet ports—0/1 and 0/2—to the logical interface port-channel group 1 on a Cisco Catalyst 2900 switch running Cisco IOS 12.2:Switch#conf tSwitch(config)#interface port-channel 1Switch(config-if)#switchport mode accessSwitch(config-if)#spanning-tree portfastSwitch(config-if)#exitSwitch(config)#interface fastEthernet 0/1Switch(config-if)#switchport mode accessSwitch(config-if)#channel-group 1 mode onSwitch(config-if)#spanning-tree portfastSwitch(config-if)#exit

In this mode, only one Ethernet interface is actively forwarding traffic at any one time. If eth0 is active and eth1 is passive and eth0 loses its connection, the HiveAP switches over to eth1. To configure a redundant interface, enter the following commands:interface eth0 bind red0 primaryinterface eth1 bind red0The interface that you specify as primary is the one that the HiveAP uses when both interfaces have network connectivity. Because the HiveAP uses eth0 as the primary interface by default, it is unnecessary to specify "primary" in the first command above. However, it is included to make the role of eth0 as the primary interface obvious. Interface Selection for the Default RouteIn cases where there are multiple active interfaces in backhaul mode, the HiveAP uses the following logic to choose which interface to use in its default route: •If there is an Ethernet interface and a wireless interface in backhaul mode, the HiveAP uses the Ethernet interface in its default route.•If there are multiple Ethernet interfaces in backhaul mode, the HiveAP chooses which one to use in its default route in the following order:•It uses red0 or agg0 if one of them has at least one member interface bound to it and its link state is UP.•It uses ETH0 if neither red0 nor agg0 has any member interfaces and the link state for ETH0 is UP.•It uses ETH1 if neither red0 nor agg0 has any member interfaces, the link state for ETH0 is DOWN, and the link state for ETH1 is UP.Note: No extra configuration is necessary on the connecting switch or switches to support a redundant interface.

Insert the RJ-45 connector into the HiveAP 340 console port, and attach the DB-9 connector to the serial (or COM) port on your management system. The management system must have a VT100 terminal emulation program, such as Tera Term Pro© (a free terminal emulator) or Hilgraeve Hyperterminal®(provided with Windows® operating systems).

Chapter 4 The HiveAP 340 Platform52 AerohiveStatus LEDsThe five status LEDs on the top of the HiveAP 340 indicate various states of activity through their color (dark, green, amber, and red) and illumination patterns (steady glow or pulsing). The meanings of the various color + illumination patterns for each LED are explained below.Power•Dark: No power•Steady green: Powered on and the firmware is running normally•Pulsing green: Firmware is booting up•Steady amber: Alarm indicating a firmware issue has occurred•Pulsing amber: Firmware is being updated•Steady red: Alarm indicating a hardware issue has occurredETH0 and ETH1•Dark: Ethernet link is down or disabled•Steady green: 1000 Mbps Ethernet link is up but inactive•Pulsing green: 1000 Mbps Ethernet link is up and active•Steady amber: 10/100 Mbps Ethernet link is up but inactive•Pulsing amber: 10/100 Mbps Ethernet link is up and activeWIFI0 and WIFI1•Dark: Wireless interface is disabled•Steady green: Wireless interface is in access mode but inactive•Pulsing green: Wireless interface is in access mode and active•Steady amber: Wireless interface is in backhaul mode but inactive•Pulsing amber: Wireless interface is in backhaul mode and active•Alternating green and amber: Wireless interface is in backhaul mode and is searching for other hive membersAntennasThe HiveAP 340 can accept up to six detachable dipole antennas. The three shorter antennas are designed for the 5 GHz band and have a 2-dBi gain. The three longer antennas are designed for the 2.4 GHz band and have a 4.9-dBi gain. These antennas are omnidirectional, providing fairly equal coverage in all directions in a toroidal (donut-shaped) pattern around each antenna (see Figure4 on page28). For greater coverage on a horizontal plane, it is best to orient the antennas vertically. So that you can easily do that whether the HiveAP chassis is mounted horizontally or vertically, the antennas hinge and swivel (see Figure5 on page53.)Although hive members automatically adjust their signal strength according to their environments, you can resize the area of coverage by increasing or decreasing the signal strength manually by entering the interface { wifi0 | wifi1 } radio power <number> command, where <number> can be from 1 to 20 and represents a value in dBm.

Deployment Guide 53 HIVEAP 340 PRODUCT OVERVIEWFigure 5 HiveAP 340 AntennasMIMOMIMO (Multiple In, Multiple Out) is a major WLAN advancement introduced in the IEEE 802.11n standard in which multiple RF links are formed on the same channel between the transmitter and receiver simultaneously. To accomplish this, the transmitter separates a single data stream into multiple spatial streams, one for each RF chain (an antenna + various digital signal processing modules linked to the antenna). The transmit antennas at the end of each RF chain then transmit their spatial streams. The recipient’s receive antennas obtain streams from all the transmit antennas. In fact, due to multipath, they receive multiple streams from each transmit antenna. The receive antennas pass the spatial streams to the digital signal processors in their RF chains, which take the best data from all the spatial streams and reassemble them into a single data stream once again (see Figure6).Figure 6 2x2 MIMO (2 Transmit Antennas x 2 Receive Antennas)ë ÙØ¦ ß²¬»²²¿ º±® ×ÛÛÛ èðîòïï¿ñ²Ô»²¹¬¸ ©¸»² º«´´§ »¨¬»²¼»¼æ ë ïëñïêŒ øïë ½³÷îòì ÙØ¦ ß²¬»²²¿ º±® ×ÛÛÛ èðîòïï¾ñ¹ñ²Ô»²¹¬¸ ©¸»² º«´´§ »¨¬»²¼»¼æ é éñèŒ øîð ½³÷The base of the antennas hinge up to 90 degrees so that you can orient the antennas independently of the orientation of the HiveAP chassis.

$Chapter 4 The HiveAP 340 Platform54 AerohiveIn previous 802.11 standards, access points and clients each employed a single set of components, or RF chain, for transmitting or receiving. Although two antennas are often used for diversity, only the one with the best signal-to-noise ratio is used at any given moment, and that antenna makes use of the single RF chain while the other antenna remains inactive. A significant improvement that MIMO introduces is to permit each antenna to have its own RF chain and for all antennas to function simultaneously. For the HiveAP340, you can connect up to three antennas per radio and configure the radio to use two or three transmit chains and two or three receive chains.1Using two or three transmit and receive chains simultaneously increases the amount of data that can flow across the WLAN and accelerates the processing of that data at each end of the wireless link.Another major aspect of MIMO is how it turns multipath signals from a curse to a boon. As a radio signal moves through space, some objects reflect it, others interfere with it, and still others absorb it. The receiver can end up receiving multiple copies of the original signal, all kind of muddled together. However, the digital signal processors in the multiple receive chains are able to combine their processing efforts to sort through all the received data and reconstruct the original message. Furthermore, because the transmitter makes use of multiple RF chains, there is an even richer supply of signals for the receive chains to use in their processing. To set the transmit and receive RF chains for a radio profile, enter the following commands:radio profile <name> transmit-chain { 2 | 3 }radio profile <name> receive-chain { 2 | 3 }There are two sets of antennas—three antennas per set—that operate concurrently in two different frequency ranges: 2.4GHz (IEEE 802.11b/g/n) and 5 GHz (IEEE 802.11a/n). Using two different frequency ranges reduces the probability of interference that can occur when numerous channels operate within the same range. Conceptually, the relationship of antennas and radios is shown in Figure7.Figure 7 Antennas and Radios\The wifi0 interface links to radio 1 (frequency range = 2.4 GHz for IEEE 802.11b/g), and the wifi1 interface links to radio2 (frequency range = 5 GHz for IEEE 802.11a). These interface-to-radio relationships are permanent.When deciding how many antennas to use, consider the types of wireless clients—802.11n only, 802.11g/n, 802.11b/g/n, or 802.11a/n—the area needing coverage, and the RF environment.1.The convention for presenting the configuration of transmitting and receiving MIMO RF chains is TxR. For example, a HiveAP 340 radio functioning in access mode might be configured to use two RF chains for transmitting and three for receiving. In that case, its configuration can be presented as "2x3". In general, the number of receive antennas is equal to or greater than the number of transmit antennas.Î¿¼·± ïÎÚ èðîòïï¾ñ¹ñ²îòì ÙØ¦Î¿¼·± îÎÚ èðîòïï¿ñ²ë ÙØ¦îòì ÙØ¦ øß÷îòì ÙØ¦ øÞ÷îòì ÙØ¦ øÝ÷ë ÙØ¦ øß÷ë ÙØ¦ øÞ÷ë ÙØ¦ øÝ÷ÎÐóÍÓß Ý±²²»½¬±®-ÎÐóÍÓß Ý±²²»½¬±®-Cut-away view of the HiveAP 340 to show the relationship of the antennas and the two internal radios$
