CHAPTERREVIEW DRAFT—CISCO CONFIDENTIAL1-1Cisco Aironet 1520 Series Outdoor Mesh Access Point Hardware Installation GuideOL-12632-031OverviewThe Cisco Aironet 1520 Series Outdoor Wireless Mesh Access Point (hereafter called the access point) is a wireless device designed for wireless client access, point-to-point bridging, point-to-multipoint bridging, and point-to-multipoint mesh wireless connectivity. The access point is a standalone unit that can be mounted on a streetlight pole, building wall, overhang, or a cable strand.access pointThe access point model LAP1522 supports two radios (2.4-GHz and 5-GHz). The access point provides client access and without the need for a license. The 5-GHz radio is dedicated to backhaul operations to reach a wired network and the 2.4-GHz radio is used for wireless clients. The access point can support 6 to 54 Mbps data rates. The access point model LAP1524 supports up to four radios operating in the 2.4-GHz, 4.9-GHz, and 5-GHz frequency bands. The access point provides client access and without the need for a license. The 5-GHz and 4.9-GHz radios are dedicated to backhaul operations to reach a wired network and the 2.4-GHz radio is used for wireless clients. The access point can support 6 to 54 Mbps data rates.The access point is manufactured in three configurations: cable, pole mount, and mesh. The cable configuration has three antenna connectors on the top of the unit, can be mounted to a cable strand, and supports power-over-cable (POC). The pole mount configuration supports two antennas on the top and bottom of the unit. It can be mounted to a pole or building wall and supports fiber-optic networks and several power options. The Mesh configuration has two antennas on the top and bottom of the unit. It can be powered by AC and only supports wireless backhaul communications to reach the wired network. It does not support hard-wired communications (cable, fiber-optic, or Ethernet) to a wired network.The access point can also operate as a relay node for other access points not directly connected to a wired network. Intelligent wireless routing is provided by the patented Adaptive Wireless Path Protocol (AWPP). This enables each access point to identify its neighbors and intelligently choose the optimal path to the wired network by calculating the cost of each path in terms of signal strength and the number of hops required to get to a controller.The access point is configured, monitored, and operated through a Cisco wireless LAN controller (hereafter called a controller) as described in the Cisco Wireless LAN Controller Configuration Guide. The Deployment Guide: Cisco Mesh Networking Solution describes how to plan and initially configure the Cisco mesh network, which supports wireless point-to-point, point-to-multipoint, and mesh deployments. The controllers use a browser-based management system, a command-line interface (CLI), or the Cisco Wireless Control System (WCS) network management system to manage the controller and the associated access points. The access point supports hardware-based advanced encryption standard (AES) encryption between wireless nodes to provide end-to-end security.This chapter provides information on the following topics: • Hardware Features, page 1-2 • Network Deployment Examples, page 1-11

REVIEW DRAFT—CISCO CONFIDENTIAL1-7Cisco Aironet 1520 Series Outdoor Mesh Access Point Hardware Installation GuideOL-12632-03Chapter 1 Overview Hardware FeaturesDual Radio OperationThe access point supports 2.4-GHz and 5-GHz radios using external antennas (see “External Antennas”).The LAP1522 model supports simultaneous dual-radio operation using a 2.4-GHz 802.11b/g radio and a 5-GHz 802.11a radio.The 5-GHz radio can operate in either the upper industrial, scientific and medical (ISM) 5.8-GHz band or the public safety 4.9-GHz band. The 5-GHz radio supports one antenna and is used for backhaul operations to the controller. Note The 4.9-GHz band requires a license and can only be used by qualified public safety operators as defined in section 90.20 of the FCC rules.The 2.4-GHz radio supports two or three antennas for multi-input, single output (MISO) operation. The access point uses two or three receivers to support maximum ratio combining (MRC) to enhance receiver performance. MRC is a technique that combines the signals from multiple receivers in a manner to optimize the signals. MRC can provide up to 3 dB of increased receive signal strength with two receive antennas or up to 5 dB with three antennas. External AntennasThe access point supports up to three N-type radio frequency (RF) antenna connectors on the top of the unit and two on the bottom of the unit. The number of active antenna connectors depends upon the access point configuration (see Antenna Connector Locations, page 1-5). All access point configurations supports multiple 2.4-GHz antennas for MISO operation, but only one 5-GHz antenna. When using the optional Cisco compact omnidirectional antennas, the 2.4- and 5-GHz antennas connect directly to the access point. The Cisco omnidirectional antennas use vertical polarization. WarningOnly trained and qualified personnel should be allowed to install, replace, or service this equipment. Statement 1030The access point has been designed to operate with the antennas listed below and with a maximum gain of 8 dBi for 2.4 GHz and 17 dBi for 5 GHz. Antennas not in this list or with a higher gain are strictly prohibited for use with the access point. The required antenna impedance is 50 ohms. To reduce potential radio interference to other users, the antenna type and its gain should be chosen so that the equivalent isotropically radiated power (E.I.R.P.) is not more than required for successful communication.Caution For directly mounted antennas, you must not add weatherproofing around the antenna connectors because the antenna drain holes might be blocked and damage the antenna.

REVIEW DRAFT—CISCO CONFIDENTIAL1-9Cisco Aironet 1520 Series Outdoor Mesh Access Point Hardware Installation GuideOL-12632-03Chapter 1 Overview Hardware FeaturesCaution To provide inline PoE, you must use the 1520 power injector (AIR-PWRINJ1500-2=). Other power injectors, PoE switches, and 802.3af power sources cannot provide adequate power, which can cause the access point to malfunction and cause over-current conditions at the power source. Caution The 1520 power injector (AIR-PWRINJ1500-2=) must be used in an indoor environment only.Note In the cable configuration, the cable modem is activated only when the access point is powered by POC or external 12 VDC power. When using only PoE power, the cable modem is deactivated.Caution When the access point is installed outdoors or in a wet or damp location, the AC branch circuit that is powering the access point should be provided with ground fault protection (GFCI), as required by Article 210 of the National Electrical Code (NEC).The Ethernet cable from the power injector to the access point (PoE-in port) must be not less than 10 ft (3.1 m).The AC power cord options are listed below: • 40-ft (15.2-m) power cord for light pole installations in the US and Canada. One end of the power cord is terminated with an access point AC power connector, and the other end is terminated with an AC plug (AIR-CORD-R3P-40NA=). • 4-ft (1.2-m) streetlight power tap adapter for light pole installations in the US and Canada (AIR-PWR-ST-LT-R3P=).Ethernet PortsThe access point supports a PoE-in port and a PoE-out port. The access point’s PoE-in port uses an RJ-45 connector (with a liquid tight adapter) to link the access point to the 10/100/1000BASE-T network. The Ethernet cable is used to send and receive Ethernet data and to optionally supply inline 56-VDC power from the power injector. The access point’s PoE-out (10/100/1000BASE-T) port uses an RJ-45 connector (with a liquid tight adapter) to provide LAN connectivity and IEEE 802.3af power to a single peripheral customer device, such as a camera or sensor gateway. The PoE-out port should not be connected to a switch or hub.Note The PoE-out port is disabled when the access point is powered by the power injector.The Ethernet MAC addresses is printed on the bottom of the access point under the LEDs (refer to the “Finding the Product Serial Number” section on page XIV).

The access point senses the Ethernet and power signals and automatically switches internal circuitry to match the cable connections.Caution To provide inline PoE, you must use the 1520 power injector (AIR-PWRINJ1500-2=). Other power injectors, PoE switches, and 802.3af power sources cannot provide adequate power, which may cause the access point to malfunction and cause possible over-current conditions at the power source.Cable ModemThe access point cable configuration contains an internal cable modem for connection to the cable network from the pole-mounted cable lines. The access point can be powered using the 40-to 90-VAC (quasi-square wave AC) power provided by the cable network. Note The access point uses a Scientific Atlanta DPC2100 cable modem board and 4015821 RF splitter. The cable modem supports these main features: • Data Over Cable Service Interface Specifications (DOCSIS) 2.0 • Backward compatibility with existing DOCSIS 1.1 and 1.0 networksMetal EnclosureThe access point uses a metal enclosure that can accommodate both indoor or outdoor operating environments and an industrial temperature operating range of –40 to 131°F (–40 to 55°C). The access point complies with NEMA 4 and IP67 requirements.Optional HardwareSome of the access point hardware options are listed below: • Fiber-optic module and take-up reel kit (GLC-FE-100BX-URGD=)—Small form-factor pluggable (SFP) module for connection to fiber-optic lines. The take-up reels are used to store excess fiber-optic cable by wrapping the cable around the reels. –Single strand fiber bidirectional optical transceiver –1.3 (transmit) /1.5 (receive) micrometer wavelength division multiplexing (WDM) function –100 Mb/s data rates –LC receptacle –Supports up to 15.5 mi (25 km) of fiber-optic cable. • Pole mount kit (AIR-ACCPMK1520=)—provides hardware for mounting the access point to a metal or wood pole, such as a streetlight pole. • Strand mount kit (AIR-ACCSMK1520=)—provides hardware for mounting the access point to a cable strand.

The access point provides 5-GHz backhaul capability to link with another access point to reach a wired network connection or to provide repeater operations for other access points. The access point plays one of two primary radio roles: a root access point (hereafter called a RAP) or the access points that relay their wireless connections to the controller are called mesh access points (MAPs). When the access point has a wired Ethernet, fiber-optic, or cable connection to the controller (through a switch), the radio role is called a RAP. A RAP is a parent node to any bridging or mesh network. A controller can support one or more RAPs, each one parenting the same or different wireless networks. There can be more than one RAP for the same mesh network for redundancy. Both RAP and MAP access points can support wireless clients using the 2.4-GHz radio.Note The access point must be configured as a RAP in the controller, whereas the MAP role is a default setting.When the access point does not have a wired Ethernet, fiber-optic, or cable connection to the controller, the radio role is called a MAP. The MAPs have a wireless connection (through the backhaul interface) to other MAPs and finally to a RAP with an Ethernet or cable connection through a switch to the controller. MAPs can also have a wired Ethernet connection to a local LAN and serve as a bridge endpoint for that LAN (using a point-to-point or point-to-multipoint bridge connection).

REVIEW DRAFT—CISCO CONFIDENTIAL1-12Cisco Aironet 1520 Series Outdoor Mesh Access Point Hardware Installation GuideOL-12632-03Chapter 1 Overview Network Deployment ExamplesWireless BackhaulThe access point supports wireless backhaul capability using the 5-GHz radio to bridge to another access point to reach a wired network connection to a controller (see Figure 1-5). The access point connected to the wired network is considered a RAP in this configuration. The remote access point is considered a MAP and transfers wireless client traffic to the RAP for transfer to the wired network. Lightweight access point protocol (LWAPP) control traffic is also transferred over this bridged link.Figure 1-5 Access Point Backhaul ExamplePoint-to-Point Bridging The access points can be used to extend a remote network by using the 5-GHz backhaul radio to bridge the two network segments as shown in Figure 1-6. To support Ethernet bridging, you must enable bridging on the controller for each access point.Figure 1-6 Access Point Point-to-Point Bridging Example148438(5.8 Ghz) (2.4 Ghz)148440

By default, this capability is turned-off for all access points. To support Ethernet bridging, you must enable bridging on the controller for each access point.Wireless client access can be provided over the bridging link; however, if bridging between tall buildings, the 2.4-GHz wireless coverage area might be limited and possibly not suitable for direct wireless client access.Figure 1-7 Access Point Point to Multipoint Bridging Example148439

REVIEW DRAFT—CISCO CONFIDENTIAL1-14Cisco Aironet 1520 Series Outdoor Mesh Access Point Hardware Installation GuideOL-12632-03Chapter 1 Overview Network Deployment ExamplesMesh NetworkThe access points are typically deployed in a mesh network configuration. In a typical mesh deployment, one or more RAPs have a wired network connection through a switch to a controller. Other remote MAPs without wired network connections use the backhaul feature to optimally link to a RAP that is connected to the wired network. In the mesh network, the links between the access points are referred to as the backhaul links.Intelligent wireless routing is provided by the patented Adaptive Wireless Path Protocol (AWPP). This enables each MAP to identify its neighbors and intelligently choose the optimal path to the RAP with the wired network connection by calculating the cost of each path in terms of signal strength and the number of hops required to get to a controller.Figure 1-8 illustrates a typical mesh configuration using MAPs and RAPs.Figure 1-8 Typical Mesh Configuration Using Access Points155631IP

REVIEW DRAFT—CISCO CONFIDENTIAL2-6Cisco Aironet 1520 Series Outdoor Mesh Access Point Hardware Installation GuideOL-12632-03Chapter 2 Mounting Instructions Safety InformationWarningDo not locate the antenna near overhead power lines or other electric light or power circuits, or where it can come into contact with such circuits. When installing the antenna, take extreme care not to come into contact with such circuits, because they may cause serious injury or death. For proper installation and grounding of the antenna, please refer to national and local codes (for example, U.S.:NFPA 70, National Electrical Code, Article 810, Canada: Canadian Electrical Code, Section 54). Statement 1052Caution Before connecting or disconnecting a power cord, you must remove AC power from the power cord using a suitable service disconnect.For additional important safety instructions for AC power cords, refer to the AC Power Cords for Cisco Aironet 1520 Series Outdoor Mesh Access Points document that shipped with your AC power cords.For safety and to achieve a good installation, please read and follow these safety precautions:1. Select your installation site with safety, as well as performance in mind. Remember: electric power lines and phone lines look alike. For safety, assume that any overhead line can kill. 2. Call your electric power company. Tell them your plans, and ask them to come look at your proposed installation. 3. Plan your installation carefully and completely before you begin. Successful raising of a mast or tower is largely a matter of coordination. Each person should be assigned to a specific task and should know what to do and when to do it. One person should be in charge of the operation to issue instructions and watch for signs of trouble.4. When installing the access point and antennas, remember:a. Do not use a metal ladder.b. Do not work on a wet or windy day.c. Do dress properly—shoes with rubber soles and heels, rubber gloves, long sleeved shirt or jacket.5. Use a rope to lift the access point. If the assembly starts to drop, get away from it and let it fall. 6. If any part of the antenna system should come in contact with a power line,do not touch it or try to remove it yourself. Call your local power company. They will remove it safely. If an accident should occur, call for qualified emergency help immediately.

REVIEW DRAFT—CISCO CONFIDENTIAL2-7Cisco Aironet 1520 Series Outdoor Mesh Access Point Hardware Installation GuideOL-12632-03Chapter 2 Mounting Instructions Avoiding Damage to Radios in a Testing EnvironmentAvoiding Damage to Radios in a Testing EnvironmentThe radios on outdoor units (bridges) have higher transmit power levels than radios on indoor units (access points). When you test high power radios in a link, you must avoid exceeding the receiver’s maximum receive input level. At levels above the normal operating range, packet error rate (PER) performance is degraded. At even higher levels, the receiver can be permanently damaged. To avoid receiver damage and PER degradation, you can use one of the following techniques: • Separate the omnidirectional antennas by at least 2 ft (0.6 m) to avoid receiver damage or by at least 25 ft (7.6 m) to avoid PER degradation.Note These distances assume free space path loss and are conservative estimates. Required separation distances for damage and performance degradation levels in actual deployments are less if conditions are not non line-of-sight. • Reduce the configured transmit power to the minimum level. • Use directional antennas, and keep them away from each other. • Cable the radios together using a combination of attenuators, combiners, or splitters to achieve a total attenuation of at least 60 dB.For a radiated test bed, the following equation describes the relationships among transmit power, antenna gain, attenuation, and receiver sensitivity:txpwr + tx gain + rx gain - [attenuation due to antenna spacing] < max rx input levelWhere:txpwr = Radio transmit power leveltx gain = transmitter antenna gainrx gain = receiver antenna gainFor a conducted test bed, the following equation describes the relationships among transmit power, antenna gain, and receiver sensitivity:txpwr - [attenuation due to coaxial components] < max rx input levelCaution Under no circumstances should you connect the antenna port from one access point to the antenna port of another access point without using an RF attenuator. If you connect antenna ports, you must not exceed the maximum survivable receive level of 0 dBm. Never exceed 0 dBm, or damage to the access point can occur. Using attenuators, combiners, and splitters having a total of at least 60 dB of attenuation ensures that the receiver is not damaged and that PER performance is not degraded.

REVIEW DRAFT—CISCO CONFIDENTIAL2-8Cisco Aironet 1520 Series Outdoor Mesh Access Point Hardware Installation GuideOL-12632-03Chapter 2 Mounting Instructions Installation GuidelinesInstallation GuidelinesBecause the access point is a radio device, it is susceptible to common causes of interference that can reduce throughput and range. Follow these basic guidelines to ensure the best possible performance: • For information on planning and initially configuring your Cisco Mesh network, refer to the Deployment Guide: Cisco Mesh Networking Solution. • Perform a site survey before beginning the installation. • Install the access point in an area where structures, trees, or hills do not obstruct radio signals to and from the access point. • The access points can be installed at any height, but best throughput is achieved when all the access points are mounted at the same height. We recommends installing the access points no higher than 40 feet to allow support for wireless clients on the ground.Note To calculate path loss and to determine how far apart to install access points, consult an RF planning expert.Site SurveysEvery network application is a unique installation. Before installing multiple access points, you should perform a site survey to determine the optimum use of networking components and to maximize range, coverage, and network performance.Consider the following operating and environmental conditions when performing a site survey: • Data rates—Sensitivity and range are inversely proportional to data bit rates. The maximum radio range is achieved at the lowest workable data rate. A decrease in receiver sensitivity occurs as the radio data increases. • Antenna type and placement—Proper antenna configuration is a critical factor in maximizing radio range. As a general rule, range increases in proportion to antenna height. However, do not place the antenna higher than necessary, because the extra height also increases potential interference from other unlicensed radio systems and decreases the wireless coverage from the ground. • Physical environment—Clear or open areas provide better radio range than closed or filled areas. • Obstructions—Physical obstructions such as buildings, trees, or hills can hinder performance of wireless devices. Avoid locating the devices in a location where there is an obstruction between the sending and receiving antennas.

REVIEW DRAFT—CISCO CONFIDENTIAL2-9Cisco Aironet 1520 Series Outdoor Mesh Access Point Hardware Installation GuideOL-12632-03Chapter 2 Mounting Instructions Installation GuidelinesBefore Beginning the InstallationBefore you begin the installation process: • Ensure that a site survey has been performed. • Ensure that your network infrastructure devices are operational and properly configured. • Ensure that your controllers are connected to switch trunk ports. • Ensure that your switch is configured with untagged access ports for connecting your access points. • Ensure that a DHCP server with Option 43 configured is reachable by your access points, or manually configure the controller information in the access point (for additional information, refer to the “Configuring DHCP Option 43” section on page F-1). • Become familiar with the access point installation components (see the “Becoming Familiar with Access Point Installation Components” section on page 2-9).Becoming Familiar with Access Point Installation ComponentsThe access point is designed to be installed in an indoor or outdoor environment, such as an interior wall or ceiling or the exterior roof overhang of a tall building or a streetlight pole.

One or more of your access points must be reconfigured as a RAP. The RAPs connect to a wired Ethernet link through a switch to the controller. The MAPs use their wireless backhaul interface to connect to a RAP to reach the controller.Follow these steps to configure a RAP on the controller GUI:Step 1 Log into your controller using a web browser.Step 2 Click Wireless. When your access point associates to the controller, your access point’s name appears in the AP Name list.Step 3 Double-click your access point’s name. Step 4 Find Mesh Information, and choose Root AP by clicking the drop down arrow in the AP Role field.Step 5 Click Apply.Step 6 Repeat Steps 2 through 5 for each RAP.Step 7 Log out from your controller, and close your web browser.Configuring a Bridge Group NameThe bridge group name (BGN) controls the association of the access points to a RAP. BGNs can be used to logically group the radios to avoid different networks on the same channel from communicating with each other. This setting is also useful if you have more than one RAP in your network in the same area.If you have two RAPs in your network in the same area (for more capacity), we recommend that you configure the two RAPs with the same BGN, but on different channels.The BGN is a string of ten characters maximum. A factory-set bridge group name (NULL VALUE) is assigned during manufacturing. It is not visible to you, but allows new access point radios to join a network of new access points. The BGN can be reconfigured from the Controller CLI and GUI. After configuring the BGN, the access point reboots.The BGN should be configured very carefully on a live network. You should always start from the farthest node (last node) from the RAP and move towards the RAP. If you start configuring the BGN in a different location, then the access points beyond this point (farther away) are dropped, as they have a different BGN.
