The connector auto-negotiates the level requirements; it automatically sets the network media support level. Note: Cabling between 10/100baseT nodes is usually through a network hub. To make a direct 10/100baseT connection between a 300-24 and a PC, use a standard ethernet crossover cable. DB9 Serial Port (configuration management) Enables you to configure the 300-24 using the RS-232 Serial Port Interface. Only Data Transmit, Data Receive, and Ground are used (pins 2, 3, and 5 respectively) - straight-through cable. Antenna Connector Enables you to connect an antenna to the 300-24. You must use an N-Type connector for all antennas. Note: All antenna installation work shall be carried out by a knowledgeable and professional installer. Ground Screw Enables you to attach a bared 18 gauge or better ground wire to ground the unit. You would use this grounding when the ground provided by the power cable is not adequate or does not meet the user’s installation requirements. Get Started Grounding the 300-24 If the power cable used in your installation does not have adequate grounding, or if the grounding does not meet your installation requirements, you will need to ground the unit using the ground screw located on the back of the unit. This might occur if you you are installing the unit on a rack, where solid chassis grounds are mandated by the installation specialists. The ground wire should be 18 gauge or better and the other end of the wire should be connected to the rack in the case of a rack mounted installation, or to the customer’s facility grounding system. Following is an enlarged view of the ground screw identified in The Back Panel on page 7: Rear View ground screw Side View ground screw hole for ground wire When you ground the unit, you need to insert the ground wire into the hole for the ground wire and then tighten the ground screw to secure the wire. With a separate ground installed, the 300-24 may have a better earth ground than the local AC power outlets; an isolation transformer or laptop PC may be required if ground loop noise becomes troublesome. Proper electrostatic precautions must be followed. Version 1.1 - 01/04/00 Completing Pre-Installation Overview Before you install the I.WiLL™ 300-24 Access Point (300-24) you must perform certain preliminary steps to ensure an effective and reliable wireless link. These steps include: • gathering your required installation tools, accessories, and power supplies • determining the physical layout of your planned link • planning your antenna and fade margin requirements • pre-configuring the stations • bench testing the units in a controlled environment Each of these steps is described in this section. Installation Requirements Before you install the 300-24, you should have the following tools and accessories available: • • • • • • • 10-32 x 3/4 Phillips oval head screws with plastic cup washers (Hammond P/N 1421 A for rack mount) 50 ohm coaxial cable (outdoor installation site) Allen Hex Driver/Allen Key 5/64" Robertson No. 0 screwdriver EPROM extractor for PLCC package EPROM extractor for DIP package Nut driver 3/16" Ensure that the 300-24 shipping package contains the following items: • • • • • • • • • Version 1.1 - 01/04/00 rubber duck antenna N-Type male to TNC female adaptor (for installing the rubber duck antenna) DB9 adaptor (F) to 6 cond (RJ11) power supply cord straight-through ethernet cable (RJ45) crossover ethernet cable (RJ45) DB9 (M) to DB25 (F) adaptor RJ11 serial port cable (14’ modular plug) RS-232 DB9 serial cable Completing Pre-Installation • I.WiLL™ 300-24 Access Point Installation and Configuration Guide • Wi-LAN Documentation CD • Warranty Card If any of the above items are not included in the 300-24 shipping package, please contact Wi-LAN customer support. See Customer Support on page 3 for information on how to contact Wi-LAN. Planning the Physical Layout Before you install the units, you must determine the physical locations for each component of your 300-24 system. When you plan the physical layout, you will need to: • use a GPS, map, or other distance measurement method to determine the physical distance between each unit You must have a professional installer assess and calculate the following: • the antenna mast height requirements and fade margins • the cable requirements including routing, between antenna and unit • the fade margin to determine the reliability of your wireless link • the weatherproofing requirements Determining the Physical Distance Between Sites Due to the high frequency and low output powers permitted in the ISM band, no obstructions can be tolerated between two antennas. You should use lightening arrestors to ground your outdoor antenna, cables, and support structures. 10 Before you install the units, use a mapping method to determine the distance between your sites. When you determine the distance, you must check the radio path to identify any obstructions in the site path between radio locations. You can contact a Wi-LAN applications engineer to confirm that you have planned an effective radio layout. See Customer Support on page 3 for more information about contacting Wi-LAN. Working with Antennas If you are installing the unit in an indoor setting, the antenna packaged with the unit will be sufficient for indoor wireless communications. If you are installing the unit in an outdoor location, a professional installer must calculate the required mast height to ensure effective communication between your radio links. When installing an outdoor antenna, the professional installer should consider: • the required height of the antenna to ensure a clear line-of-site between the RF links • regulatory restrictions, such as height, on antenna mast usage in the identified location • obtaining permission from building owners if you intend to install your antenna on a rooftop • potential wind load and ice loading impact on the antenna • grounding requirements. The antenna must be properly grounded for lightening in accordance with the relevant electrical code for the installation location. See Working with Antenna Gain on page 19 or see the 300-24 Product Specification for more information about installing and selecting antennas in outdoor locations. Version 1.1 - 01/04/00 Pre-configuring the Stations Determining Cable Requirements If you are installing the antenna in an outdoor location, you will require 50 ohm coaxial cable to connect the unit to the antenna. You must minimize the length of the cable between the unit and antenna; the longer the cable length the greater the dB loss. You must calculate the required cable lengths before you install the 300-24. Notes: • You should use surge suppressors at the point of cable entry into the building. • All cabling work must be carried out by a professional installer. Working with Fade Margins Once you’ve identified the physical locations of your antennas, the height of the antennas, and the cable length required, you can calculate the fade margin for your wireless link. The fade margin enables you to predict the reliability of your wireless link. See Calculating Path Loss on page 22 for more information about fade margins. Note: The fade margin work must be carried out by a professional installer. Assessing the Weatherproofing Requirements Use surge suppressors at the point of cable entry into your building. All 300-24 units must be located in a weatherproof environment with an ambient temperature between 0º and 30º Celsius. You must consider the building, heating, and air conditioning requirements to ensure that the unit operates within these conditions. Pre-configuring the Stations Typically, the physical layout of a 300-24 system involves significant distances between units. To ensure the efficiency of your wireless links you must pre-configure the following: • a base station • remote stations • the polling list You must assign each 300-24 unit a unique RF Station ID and configure the polling list before the unit will function properly. These steps must be completed and verified before you install any units. Pre-configuring Stations See Configuring Using the Menus on page 31 for instruction on using all of the configuration menus. Version 1.1 - 01/04/00 You must designate each 300-24 unit as a base or remote station and assign each 300-24 unit with a unique RF Station ID. 11 Completing Pre-Installation Differences Between the Remote and Base Station Menus The options that appear in the Main System menu vary depending whether you configured the 300-24 unit as a base station or as a remote station.

Version 1.1 - 01/04/00 15 Completing Pre-Installation Bench Testing the 300-24 Before you deploy the 300-24 unit into a network configuration, you should familiarize yourself with the equipment by bench testing the unit in a controlled environment. The receiver portion of the 300-24 unit is extremely sensitive, and the high sensitivity of the radio receiver can make testing in small environments difficult. Close proximity of the transmitter will overwhelm the radio’s receiver. When you conduct your bench test, ensure that there is five feet between the two units. You will need the following equipment to bench test the unit: • 2 x portable or laptop computers with functioning 10/100 Ethernet adaptors • 1 x 5 feet RG58 cables (terminated N Male x SMA Female) • 1 x 5 feet RG58 cables (terminated N Male x SMA Male) • 1 x 60 dB attenuation @ 2.44 Ghz (can be accommodated by 2 x 30 attenuators) • 1 x straight-through RS232 cable DB9 x DB9 • 2 x Ethernet crossover cable To bench test the 300-24 1. Use one of the Ethernet crossover cables to set up a peer-to-peer network between the two PCs. 2. Verify network operation by transferring a file between the two PCs. 3. Pre-configure each of the 300-24 units. Refer to Pre-configuring the Stations on page 11 for instructions on pre-configuring the units. 4. Insert the attenuation between the two RG58 cables. 5. Connect the opposite ends of the cables to each 300-24 unit. This creates a controlled path between the units of a known path loss. 6. Perform the link test between the two units. Refer to Viewing the MAC Layer Statistics on page 39 and Appendix B: Monitor and Test Links on page 75 for information about link tests. Using the required cables and attenuation for this bench test, the fade margin should be 32 dB (± 3 dB). 7. Finally, connect each PC to the 300-24 devices via the Ethernet cables. 8. Transfer a file using the same file transfer protocol used in step 2. The systems are now tested and configured for deployment into the network system. 16 Version 1.1 - 01/04/00 Determining the RF Link Overview This section provides details about how to obtain the maximum range from your RF link. The effectiveness and reliability of your RF link depends on the following: • antenna gain • distance between antennas and obstructions in the RF path • above-ground height of the antennas • length and type of coaxial cable connecting the 300-24 and the antenna The above factors are used to calculate your link budget. The link budget calculation indicates if your radio link is feasible over a given distance and path and if your RF link meets regulatory requirements. Link budgets are typically expressed in decibel (dB) format. Calculating the Link Budget Specific calculations must be completed to determine your link budget. This section describes the calculations and includes definitions of the terms and variables used in the calculations. The following dB terms are used in this section: Term Description dB Decibel. A relative measure of power used to specify power gains and losses. The difference in power P1 and P2 expressed in dB is: P1 dB = 10 × log ------- P2 Version 1.1 - 01/04/00 dBd The gain or loss of an antenna reference to a standard dipole. Gain of a Standard Dipole = 2.14 dBi. dBi The gain or loss of an antenna referenced to an isotropic (theoretical point source) radiator. This measure is used with only antennas, as it quantifies gain or loss of a physical radiator with respect to a theoretical one. dBm A power measurement referenced to one milli-Watt. This is an absolute measure of power rather than a relative measure such as a gain or a loss. 17 Determining the RF Link Link Budget Variables You will use the following variables when you calculate the link budget: Variable Description System Gain The maximum path loss that the system can support for usable data transmission. ERP (Effective Radiated Power) The power radiating from an antenna taking into account the output power from the transmitter, connector losses, cable losses, and the antenna gain. Sensitivity The minimum signal strength required for usable performance. Expressed in dBm. Antenna Gain Gain of the antenna over a dipole (dBd) or theoretical (dBi). Propagation Loss The signal loss experienced as it travels through the air. Expressed in dB. Cable Loss The signal loss experienced as it passes through the coax cable. Expressed in dB. Path Loss The total loss from one end of the path to the other. This includes propagation losses, cable losses, and any other losses that impact the system performance. Working with System Gain Proper path planning ensures that each end of the RF link receives sufficient signal power to maintain a desired Bit Error Rate (BER). The system gain of a radio system is the difference between the transmitted power and the receiver’s sensitivity threshold. See Link Budget Variables on page 18 for definitions of these terms. Using this relationship, the system gain of the 300-24 is: 18 Formula: System Gain = Tx Power - Rx Sensitivity Variables: Tx Power Receiver Sensitivity = Calculation: 93dB = 15dBm - -78dBm More info: To ensure reliable communications, the system gain plus all antenna gains must be greater than the sum of all losses. For a reliable link it is recommended that the system gain plus all antenna gains be greater than the sum of all losses by a factor of 13dB. This factor is known as the Fade Margin. 15dBm -78dBm nominal for quasi-error free (BER 10-9) operation Version 1.1 - 01/04/00 Calculating the Link Budget Calculating ERP (Effective Radiated Power) Unlike the Tx output power of the devices, ERP is subject to both antenna gain and cable losses. ERP is the power radiating from an antenna taking into account the output power from the transmitter, the connector and cable losses, and the antenna gain. Because many antennas can provide a directional gain, the effective radiated power can increase. Losses, such as cable losses can subtract from this amount. You calculate the ERP as follows: Formula: ERP = Tx Power (dBm) - Cable Losses (dBm) - Connector Losses (dBm) + Antenna Gain (dB) Note: The FCC regulatory body has set the ERP limit to +36dBm for fixed point-to-point applications per FCC 15.247(b)(3)(i). Industry Canada RSS-139, Annex B specifies the maximum transmitter output at +30dBm, with a maximum EIRP (Equivalent Isotropically Radiated Power) at +36dBm for multi-point configurations and a maximum EIRP of +53dBm only for licensed point-to-point applications. In accordance with ETS 300-328 for 2.4GHz RLANs, the maximum EIRP shall not exceed +20dBm, with a maximum SPD (Spectral Power Density) not exceeding +10dBm/MHz. Confirmation is required with the relevant European national radio communications local authority for deviations from this specification. Note: All ERP work must be completed by a professional installer. Working with Antenna Gain To ensure the best range and interference suppression, the external antenna should be directional, focusing the radio energy in one direction (toward the other end of the link). The direction can be azmuthal or a horizontal radiation angle. A directional antenna focuses the RF energy to the intended station rather than omni-directionally. This reduces interference from other systems that are operating at the same frequency. Note: In some situations, you may want to use an omni-directional antenna in your system design. For example, you would use an omni-directional antenna for a base station with remote sites situated in a 360º path around it. When you select an antenna, pay particular attention to the gain specification. When you select an antenna for a remote station, select an antenna with a gain that provides at least 13dB Fade Margin. Antenna gain is specified in either dBi or dBd. When an antenna is specified in dBd, add 2.14dB to the value to convert it to dBi. Note: All antenna gain work must be completed by a professional installer. Version 1.1 - 01/04/00 19 Determining the RF Link Calculating Propagation Loss The propagation loss is the attenuation (reduction) in RF signal energy as it travels through space. In most wireless systems, losses through space are the major contributor to signal attenuation. When you know the intended installation locations of the base and remote stations, determine the physical line of sight distance and then calculate the RF attenuation as follows: Formula: Attenuation (dB) = 100dB + 20log(dkm) where: dkm = Distance in Kilometers 100dB = Pathloss Constant Note: The FCC regulatory body has set the ERP limit to +36dBm for fixed point-to-point applications per FCC 15.247(b)(3)(i). Industry Canada RSS-139, Annex B specifies the maximum transmitter output at +30dBm, with a maximum EIRP (Equivalent Isotropically Radiated Power) at +36dBm for multi-point configurations and a maximum EIRP of +53dBm only for licensed point-to-point applications. In accordance with ETS 300-328 for 2.4GHz RLANs, the maximum EIRP shall not exceed +20dBm, with a maximum SPD (Spectral Power Density) not exceeding +10dBm/MHz. Confirmation is required with the relevant European national radiocommunications local authority for deviations from this specification. Note: All propagation loss work must be completed by a professional installer. Working with the Fresnel Zone It is essential to locate your antennas at maximum above-ground height to ensure the most effective and reliable link. Achieving maximum above-ground antenna height means that: • all ground-based obstructions are cleared from the line-of-sight path • the Fresnel Zone is clear of obstructions 20 Version 1.1 - 01/04/00 Calculating the Link Budget The Fresnel Zone is the expansion of the RF signal radio angles in the vertical plane near the middle of the RF path. Following is a basic illustration of the Fresnel Zone concept: First Fresnel Zone Line of Sight The maximum Fresnel Radius indicates that this path must be kept clear of obstructions. Fresnel R adius G round The Fresnel radius is calculated as follows: Formula: Fresnel Zone Radius = 3.4 × d km + ----------- metres 8.12 Calculating Cable Loss Installations involving cable runs longer than a few feet must use highquality, low loss shielded coax. The wireless link is subject to implementation losses such as cable and connector losses. The two primary coaxial cable specifications for the 300-24 are: • cable must be 50 ohms nominal impedance • cable must be of a low loss type Generally, cable losses are specified in dB/foot or dB/meter. Following is an example of cable loss ratings: Cable Type dB/foot dB/meter LMR400 0.0684 0.220 LMR600 0.0441 0.142 Notes: • When you calculate path loss, you should add 1dB at each end of the link to compensate for connector losses in addition to the cable loss value. • All cable loss work must be completed by a professional installer. Version 1.1 - 01/04/00 21 Determining the RF Link Calculating Path Loss Path loss describes the total RF attenuation throughout the system from Tx antenna to Rx antenna. This includes the losses as the RF signal travels through space plus Tx and Rx cable loss, and Tx and Rx connector loss. Use the following formula to calculate path loss: Formula: Path Loss = Tx and Rx Cable Loss + Tx and Rx Connector Loss + Propagation Loss Once you know the path loss, you can compare the value to the system gain value. If the system gain value is greater than the path loss, the link is feasible. See Working with System Gain on page 18 for more information about system gain. Note: All path loss work must be completed by a professional installer. Total antenna gain is: Tx Antenna Gain + Rx Antenna Gain 22 Working with the Fade Margin The amount that the system gain plus the total antenna gain exceeds the path loss is called the Fade Margin. The Fade Margin is calculated as the number of dB that the received signal strength exceeds the minimum receiver sensitivity. You require some level of Fade Margin for any wireless system. The Fade Margin compensates for RF path fading due to weather conditions or nearby objects that induce multi-path signaling. The Fade Margin for the 300-24 is a minimum of 13dB. The sum of the cable losses, connector losses, propagation losses, and the 13dB required Fade Margin should be less than the system gain value of 93dB. Note: All fade margin work must be completed by a professional installer. Version 1.1 - 01/04/00 Link Budget Example Link Budget Example Putting everything together, you must satisfy the following equation to have a successful link: The values for cable and connector losses in this example are only for illustration. You will need to work these out for your specific installations. or Fade Margin ≥ System Gain + Antenna Gain - Propagation Loss Cable Losses - Connector Losses where: System Gain = Tx Power - Rx Sensitivity Antenna Gains = Tx Antenna Gain + Rx Antenna Gain Cable Losses = Base Cable Losses + Remote Cable Losses Connector Losses = Base System Connector Losses + Remote System Connector Losses Variables: Version 1.1 - 01/04/00 System Gain + Antenna Gain ≥ Propagation Loss + Fade Margin + Cable Losses + Connector Losses Formulas: Desired Fade Margin 13dB Tx Power Rx Sensitivity Tx Antenna Gain Rx Antenna Gain Propagation Loss for desired range of 1km Tx Cable Losses (2m LMR400) Rx Cable Losses (2m LMR 400) Tx Connector Losses Rx Connector Losses 15dBm -78dBm 9dB 15 dB 100 + 20 × log 〈 1〉 = 100dB .44dB .44dB .5dB .5dB Variable Calculations: System Gain = 15dBm - -78dBm = 93dBm Antenna Gains = 9dB + 15dB = 24dB Cable Losses = .44dB + .44dB = .88dB Connector Losses = .5dB + .5dB = 1dB Fade Margin Calculation: Fade Margin = 93dB + 24dB - 100dB - .88dB - 1dB = 15.12dB Analysis: We have achieved the goal of a Fade Margin ≥ 13dB. 23 Determining the RF Link Verifying a Link Budget You need to verify the link budget in both directions: base station to remote station and remote station to base station. To verify the link budget calculations, from the 300-24 user interface, measure the Received Signal Strength Indicator (RSSI), Null Depth, and the Fade Margin. Note: The effects of multi-path are not the same in both directions of a link and you need to verify the link budget in both directions. Following are descriptions of the link statistics you need to measure: Term Description Null Depth The difference in strength between the strongest and weakest OFDM carriers. A Null Depth of more than a few dB indicates the receiver is experiencing multi-path effects which are partially canceling the signal. If the Null Depth is more than 3dB, it should be compensated by moving the receiving antenna or increasing the antenna gain. RSSI A numeric indication of the received signal strength in dBm. Reviewing the Link Statistics See Viewing the MAC Layer Statistics on page 39 for more information about the MAC Layer Statistics window. Once you set up the link and select the Mac Layer Statistics window in the user interface, you can measure the RSSI, Null Depth, and Fade Margin to ensure that the link is functioning properly. See Appendix B: Monitor and Test Links on page 75 for more information about monitoring link statistics after the system installation is complete. You need to measure: • Null Depth • Bit Error Rate (BER) Interpreting the Null Depth When you interpret the link statistics, you need to subtract the Null Depth from your budgeted Fade Margin. For example, if you budgeted a 13dB Fade Margin, and you have an indicated Null Depth of 3dB and an indicated Fade Margin of 10dB, then your calculations were correct. Budgeted Fade Margin = Indicated Null Depth + Indicated Fade Margin where: 13dB = 3dB + 10dB For small Null Depths, you will typically proceed with a reduced Fade Margin as long as the number of uncorrected errors is zero, or is incrementing very slowly during peak traffic periods. 24 Version 1.1 - 01/04/00 Verifying a Link Budget Interpreting Bit Error Rate (BER) The BER after Reed-Solomon Forward Error Correction (RS FEC) can be computed from the number of uncorrected byte errors and the total number of frames received. The following constants are used in the calculation: • 1536 bytes per frame • 8 bits per byte • 1.25 bit errors per uncorrected byte error (on average) From these values, the following formula is structured: BER = 1.25 x Uncorrected Bytes / (Number of Frames x 1536 x 8) You need to accumulate approximately 80 byte errors, or 100 bit errors, to receive statistically significant results. The final test of a good link, is when the BER on the monitoring computer is 10-9 or better. Version 1.1 - 01/04/00 25 Determining the RF Link 26 Version 1.1 - 01/04/00 Installing Base and Remote Stations Overview Once you have determined the RF link and configured the units, you can install the 300-24 units at the site locations. Installing the Antenna If your antennas will be located on a support structure, or on top of a tower, you should have a professional tower worker complete the antenna installation. When you install the antenna, ensure that: If you are using rubber duck or rubber dipole antennas, they should be pointed vertically (up). • • • the antennas for the system have the same polarity (vertical or horizontal). all connectors attaching the coaxial cable to the antenna are properly weatherproofed. a drip loop is formed at the building entrance, to prevent water flowing down the coaxial cable from entering the installation building. • the coaxial cable is secured to the supporting structure at one meter intervals. This will prevent wind damage and frost loading problems. • the antenna is firmly attached to the mast to prevent it from falling, yet has some flexibility so that you can move the antenna to fine-tune antenna position. • the coaxial cable is connected to the antenna and to the antenna port on both sides of the link (base and remote stations). Note: All antenna installation work must be completed by a professional installer. Powering Up the Units Before you power up the units, ensure that the AC Power Level Switch on the back panel of the unit is set correctly. An incorrect power level setting can cause serious damage to the unit when it is powered up. When you successfully power up the unit, the Power LED on the front panel will initially be orange, and then change to green. See Front Panel LEDs on page 6 for more information about the LED display. You need to verify that your hardware and software revision numbers match those on the data list shipped with the unit. If the numbers do not match, contact Wi-LAN customer support. See Contacting Customer Support on page 3 for more information about contacting Wi-LAN. Version 1.1 - 01/04/00 27 Installing Base and Remote Stations To verify the revision numbers 1. Access the Configuration menus using Telnet or RS-232. See Accessing the Menus on page 31 for more information about accessing the Configuration menus and logging into the system. 2. Access the System Revision Information window and verify that the hardware and software revision numbers shown in the window match those on the data list shipped with the unit. See Viewing System Revision Information on page 35 for more information about viewing the System Revision Information window. Verifying the RF Port You can connect two units together back to back via an RF cable to verify the RF port. You need to ensure that: • you have at least 70dB of RF attention between the RF ports of the two units. • the units are at least 10 meters apart. • you connect a 30dB attenuator directly to each RF port to minimize cross-talk between units. • the attenuators have at least a 20dBm power rating. • you add another 10dB of attenuation between the units, either at one end or in between the units. To verify the RF port 1. Access the Configuration menus and verify the following: 28 Verify that... For more information see... The IP addresses are unique for each unit. To set the Internet IP address on page 52. The IP Masks are the same for both units. To set the Internet IP mask on page 52. The MAC addresses are unique for both units.

Version 1.1 - 01/04/00 Powering Up the Units Verify that... For more information see... The host computers connected to the units have unique IP addresses with respect to themselves and the units. Setting the Internet IP Address on page 52. 2. From each end of your two unit connection, ping the unit from the wire and wireless sides. 3. From each end of your two unit connection, telnet to the unit from the wire and wireless sides. If you can successfully communicate to all units through ping and telnet, your RF port is verified. Fine-tuning Antennas The link statistics display in real time. Any changes to the antenna position are immediately represented in the link monitoring screen. You can fine-tune the antennas by generating consistent steady traffic through the 10/100BaseT port at one end and then, at the receiving end, connecting a PC via the RS-232 to monitor the link statistics. You can ping the computer to create steady traffic. Ensure that the link statistics show an adequate Fade Margin and that the Null Depth is less than 4dB. See Appendix B: Monitor and Test Links on page 75 for information about monitoring the link statistics. Reposition the antennas until the required link statistics values are achieved. Once the antennas have been adjusted to maximize performance, you can secure them properly to the support structures. Note: All antenna fine-tuning must be completed by a professional installer. Completing the Installation Connections Once the antennas are properly positioned, you need to connect the 300-24 to its LAN segment. You complete this connection as you would connect a PC to a LAN segment. Note: Cabling between 10/100baseT nodes is usually through a network hub. To make a direct 10/100baseT connection between a 300-24 and a PC, use a standard crossover cable. You must swap pins 1 & 3 and 2 & 6. Once the connection is complete, the 300-24 unit is ready for network traffic. Version 1.1 - 01/04/00 29 Installing Base and Remote Stations Installing the Units on a Rack You can mount the 300-24 unit in a rack. The face plate and hardware for rack installations is included in the 300-24 shipping package. Following is an illustration of how to attach the face plate to the 300-24: The unit is designed for installation in a 19 inch rack that is 3U high. 30 Version 1.1 - 01/04/00 Configuring Using the Menus Overview This section includes some general information about: • accessing and modifying the configuration settings • working with the configuration menus to define your 300-24 system settings You can use the following methods to access and configure the 300-24 units: • Telnet • RS-232 Management Port • SNMP See Using SNMP on page 65 for information about using SNMP. You can configure any unit as a base or a remote station. Each system configuration includes only one base station, however it can include multiple remote stations. If you need a true wide area network where all sites pass all data packets, the base and remote stations need to communicate directly with each other. Every station will receive and decode all packets and a true LAN/WAN network is created from individual segments. Navigating the Configuration Menus You use the keyboard keys to highlight and apply configuration options in the configuration menus. See Conventions Used in this Guide on page 2 for descriptions of the menu selection conventions used in this guide.

Version 1.1 - 01/04/00 63 Configuring Using the Menus 64 Version 1.1 - 01/04/00 Using SNMP Using the Wi-LAN SNMP MIB Included with each I.WiLL™ Access Point 300-24 unit (300-24), is a Simple Network Management Protocol (SNMP) permitting configuration, monitoring, and control of: • base stations via the ethernet • remote units via the air Units in remote and hard-to-reach locations can be easily configured, and network managers can avoid or reduce downtime by monitoring network throughput, packet collision rates, and interference. SNMP is a protocol you can use to remotely manage a network element by polling, setting terminal values, and monitoring network statistics and events. It is the de-facto internet work management standard, designed to provide a mechanism for the exchange of management information in a TCP/IP-based internet environment. SNMP consists of the following three elements: Version 1.1 - 01/04/00 SNMP Element Description Manager This element is installed on the network’s host computer and is controlled by the network administrator. From the host, the Manager configures Agents, or polls Agents for information. Agent The Agent runs on each unit. An Agent accepts configuration commands from the Manager and collects network and terminal information specified in the MIB. Management Information Block (MIB) The MIB is a database which is accessed by a specific set of commands that you can execute using the SNMP Manager. There is a standard MIB and a Wi-LAN customized MIB that stores information relevant to the operation of a wireless network. 65 Using SNMP Using the Wi-LAN MIB Object Identifier Nodes All OID (Object Identifier) nodes in the private Wi-LAN MIB are numbered 1.3.6.1.4.1.2686.n where n is a private Wi-LAN MIB node number or branch of numbers. This number is used in the nodes in the following pages. All nodes containing statistical information are cleared on powerup and reset. Values in all writeable nodes are stored in Flash memory and are retained until overwritten by the administrator, even following power down or reset. 66 Version 1.1 - 01/04/00 Version 1.1 - 01/04/00 Wi-LAN MIB Object Identifier Nodes Following are descriptions of the nodes in the MIB for the 300-24: Address/Node Object Type Syntax Access Description 1.1.1 1.3.6.1.4.1.2686.1.1.1 defaultImage INTEGER R/W File descriptor id of Image to boot on hard drive. 1.1.2 1.3.6.1.4.1.2686.1.1.2 ipAddr IpAddress R/W ENET/OFDM bridge IP address. 1.1.3 1.3.6.1.4.1.2686.1.1.3 ipMask IpAddress R/W ENET/OFDM bridge IP mask 1.1.4 1.3.6.1.4.1.2686.1.1.4 macAddr PhysAddress R/W ENET interface MAC address 1.1.5 1.3.6.1.4.1.2686.1.1.5 gatewayIpAddr IpAddress R/W Default Gateway IP address 1.1.6 1.3.6.1.4.1.2686.1.1.6 snmpNmsIpAddr IpAddress R/W SNMP NMS IP Address (Trap Destination) 1.1.7 1.3.6.1.4.1.2686.1.1.7 routingType INTEGER (1, 3) R/W IP Routing Type: Bridge (1), Filter (3) 1.1.8 1.3.6.1.4.1.2686.1.1.8 stationType INTEGER (1, 2) R/W OFDM Station Type: Base-Stn (1) or Remote (2) 1.1.9 1.3.6.1.4.1.2686.1.1.9 radioId INTEGER (0..1023) R/W RF Station Identifier 1.1.10 1.3.6.1.4.1.2686.1.1.10 networkId INTEGER (0..1023) R/W RF Network Identifier 1.1.11 1.3.6.1.4.1.2686.1.1.11 centerFreq INTEGER R/W RF Center Frequency (2.410, 2.415, 2.430, 2.440, 2.450, 2.465, 2.470) 1.1.121.1.21 1.3.6.1.4.1.2686.1.1.12 to 1.3.6.1.4.1.2686.1.1.21 vector1 to vector 10 INTEGER (0..65535) R/W RF Randomization Vector 1 to RF Randomization Vector 10 1.1.22 1.3.6.1.4.1.2686.1.1.22 userPassword DisplayString (Size 0..31) R/W System Login User-Level Password 1.1.23 1.3.6.1.4.1.2686.1.1.23 superPassword DisplayString (Size 0..31) R/W System Login Supervisor-Level Password 67 Using the Wi-LAN MIB Object Identifier Nodes Node # Version 1.1 - 01/04/00 Address/Node Object Type Syntax Access Description 1.1.24 1.3.6.1.4.1.2686.1.1.24 autoLogoutMins INTEGER R/W Input Inactivity Auto-Logout Timeout (minutes) 1.1.25 1.3.6.1.4.1.2686.1.1.25 ethernetAccess INTEGER (0, 1) R/W Enable/Disable Configuration Access Via Ethernet: Disabled (0), Enabled (1) 1.1.26 1.3.6.1.4.1.2686.1.1.26 wirelessAccess INTEGER (0, 1) R/W Enable/Disable Wireless Configuration Access: Disabled (0), Enabled (1) 1.1.27 1.3.6.1.4.1.2686.1.1.27 publicName DisplayString (Size 0..31) R/W SNMP Public Community Name 1.1.28 1.3.6.1.4.1.2686.1.1.28 privateName DisplayString (Size 0..31) R/W SNMP Private Community Name 1.1.29 1.3.6.1.4.1.2686.1.1.29 ipFilterTable SEQUENCE of IpFilterEntry NA The list of IP Filter Table entries. 1.1.29.1 1.3.6.1.4.1.2686.1.1.29.1 ipFilterEntry IpFilterEntry NA An IP Filter entry containing the IP address and mask of the filter. 1.1.29.1.1 1.3.6.1.4.1.2686.1.1.29.1.1 ipFilterIndex INTEGER RO The 1-relative index of the filter in the table. 1.1.28.1.2 1.3.6.1.4.1.2686.1.1.28.1.2 ipFilterAddr IpAddress R/W The IP Filter net or host IP address. 1.1.28.1.3 1.3.6.1.4.1.2686.1.1.28.1.3 ipFilterMask IpAddress R/W The mask applied to the filter host or net address. addr & mask = host or net number.

All link mode statistics appear in the MAC Layer Statistics window. See Viewing the MAC Layer Statistics on page 39 for detailed information about the window. You need to monitor the following three link mode statistics: • • • Received Signal Strength Indicator (RSSI) Null Depth Fade Margin Monitoring RSSI The RSSI is the strength of the received signal in dBm (decibels referenced to a milliWatt). When monitoring the RSSI, ensure that it meets the following statistical criteria: RSSI Element Required Measurement Noise Floor -95dBm Signal to Noise Ratio 17dBm for quasi error free operation Quasi Error Free 1 error in 109 bits after forward error correction RSSI Required for Quasi Error Free Operation -95dBm + 17dBm = -78dBm Receiver Sensitivity -78dBm In a real application, a fade margin is required to allow for rain fading or other reception anomalies. See Monitoring Fade Margin on page 76 for more information. At the other extreme, the receive signal strength cannot be greater than -45dBm or the receive LNA will saturate. If the RSSI is greater than -45dBm you must add sufficient attenuation at the remote site to bring the RSSI down to an acceptable level. Note: Check the back of the 300-24 unit for a label identifying that a RSSI Correction Factor has been applied to the unit. If so, apply the following correction factor: Actual_RSSI = RSSI - RSSI_Correction_Factor Version 1.1 - 01/04/00 75 Appendix B: Monitor and Test Links Monitoring Null Depth The Null Depth is the ratio in dB between the strongest OFDM carrier and the weakest carrier. A Null Depth of greater than 0 dB indicates that there is no multipath reception. Some multipath is usually present in your link, however adjustments to the position or location of the receive antenna at the remote site can minimize the Null Depth. In some cases, you cannot adjust the antenna position and location of the receive antenna at a remote site. Monitoring Fade Margin The Fade Margin is the receive power in excess of the minimum required for error free operation. See Monitoring RSSI on page 75 for information about receive power. Fade Margin is computed for you using the following formula: Formula Fade Margin = RSSI - Null Depth - Receiver Sensitivity Example Variables RSSI Null Depth Receiver Sensitivity Fade Margin Calculation Fade Margin = -62dBm - 3dB - -78dBm Fade Margin = 13dB -62dBm 3dB -78dBm 13dB Thus, we have verified that the correct Fade Margin of 13dB is displayed. Note: Check the back of the 300-24 unit for a label identifying that a Fade Margin Correction Factor has been applied to the unit. If so, apply the following correction factor: Actual Fade_Margin = Fade_Margin - Fade_Margin_Correction_Factor Performing a Link Test Linktest is a diagnostic tool for setting up and diagnosing links. Typically, you use linktest when you: • initially set up a remote • diagnose a problem link Linktest generates pseudo-random packets of information that are transmitted to the station ID provided. The unit, or station ID, compares the pseudo-random data and accumulates bit errors, RSSI, Fade Margin, and Forward Error Correction (FEC) statistics. These statistics and regenerated pseudo-random data are sent in a packet back to the originating unit. The originating unit then compares the pseudo-random data and at approximately one second intervals, displays the accumulated statistics in the configuration menus. Before you start a linktest, you need the station ID of the base station. See Setting the RF IDs and Center Frequency on page 58 for information about viewing station ID settings. 76 Version 1.1 - 01/04/00 Performing a Link Test To start a linktest 1. At the remote station from which you are performing the linktest, access the configuration menus. See Accessing the Menus on page 31 for more information about accessing the menus. 2.

Version 1.1 - 01/04/00 81 Appendix C: Upgrading Software 82 Version 1.1 - 01/04/00 Glossary agent In a SNMP context, the agent runs on each unit. An agent accepts configuration commands from the manager and collects network and terminal information specified in the MIB. antenna A device which takes electromagnetic energy from a circuit or wire and radiates it into space rather than confining it. antenna gain Gain of the antenna over a dipole (dBd) or theoretical (dBi). attenuation Any loss in signal strength, due to resistance, absorption, capacitance, or any characteristic of the medium or design of the system. bandwidth The span in hertz, that the information-bearing signal occupies or requires, or the difference in hertz between the lowest and highest frequencies of a band. baud A measurement unit which defines the number of symbols per second (or signaling units per second). BER Bit Error Rate. A percentage of bits per million, showing the number of bits in error compared to the data bits actually sent. Version 1.1 - 01/04/00 83 Glossary cable loss The signal loss experienced as it passes through the coax cable. Expressed in dB. channel The width of the spectrum band taken by a radio signal, usually measured in kilohertz (kHz). chip rate Chip rate signifies the time occupied by that single frequency. Also the period of a code clock, or the output of a code generator during one clock interval. coaxial cable A type of wire where the inner conductor is surrounded by an outer conductor. The outer conductor serves as an electrical shield. collision The situation that exists when two users try to send a signal over the same medium at the same time, and the signal uses the same frequencies. CRC Cyclic Redundancy Checksum Code. Based on mathematical theories, the CRC allows a small number of checking bits to show whether the overall stream of bits has any errors in it. dB Decibel. A relative measure of power used to specify power gains and losses. The difference in power P1 and P2 expressed in dB is: P1 dB = 10 × log ------- P2 dBd The gain or loss of an antenna referenced to a standard dipole. Gain of a Standard Dipole = 2.14 dBi. dBi The gain or loss of an antenna referenced to an isotropic (theoretical point source) radiator. This measure is used with only antennas, as it quantifies gain or loss of a physical radiator with respect to a theoretical one. dBm A power measurement referenced to one milli-Watt. This is an absolute measure of power rather than a relative measure such as a gain or a loss. DB9 A D-shaped connector with 9 pins. 84 Version 1.1 - 01/04/00 E EEPROM Electrically Erasable Programmable Read-Only Memory. Non-volatile memory. ERP Effective Radiated Power. The power radiating from an antenna taking into account the output power from the transmitter, connector losses, cable losses, and the antenna gain. ETSI European Telecommunications Standards Institute. fade margin The amount that the system gain plus the total antenna gain exceeds the path loss is called the fade margin. The fade margin is calculated as the number of dB that the received signal strength exceeds the minimum receiver sensitivity. Fresnel Zone The Fresnel Zone is the expansion of the RF signal radio angles in the vertical plane near the middle of the RF path. IEEE Institute of Electrical and Electronics Engineers. interference Any signal that tends to hamper the normal reception of a desired signal. ISM Industrial, Scientific, and Medical. It is the license-exempt radio band in North America and some European countries. It is also referred to as part 15.247 in the FCC regulation that defines the parameters for use of the ISM band in the U.S., including power outputs, spread-spectrum, and noninterference. MAC Address Media Access Controller Address. Alphanumeric characters that uniquely identify a network-connected device. Management Information Block See MIB. manager When used in SNMP, this element is installed on the network’s host computer and is controlled by the network administrator. From the host, the manager configures agents, or polls agents for information. Version 1.1 - 01/04/00 85 Glossary MIB Management Information Block. The MIB is a database which is accessed by a specific set of commands that you can execute using the SNMP Manager. There is a standard MIB and a Wi-LAN customized MIB that stores information relevant to the operation of a wireless network. OID nodes Object Identifier Nodes. These are the individual nodes in a MIB. See SNMP and MIB. path loss The total loss from one end of the path to the other. This includes propagation losses, cable losses, and any other losses that impact the system performance. propagation loss The signal loss experienced as it travels through the air. Expressed in dB. RF System of communication employing electromagnetic waves propagated through space. Because of varying characteristics, radio waves of different lengths are employed for different purposes and are usually identified by their frequency. RS-232/422/423/485 Standards for serial communications, which define the voltages, currents, data rates, and other factors about the signals to be used, as well as single-ended, differential, and multi-drop operation. sensitivity The minimum signal strength required for usable performance. Expressed in dBm. SNMP Simple Network Management Protocol. A protocol you can use to remotely manage a network element by polling, setting terminal values, and monitoring network statistics and events. It is the de-facto internet work management standard, designed to provide a mechanism for the exchange of management information in a TCP/IP-based Internet environment. spread spectrum Any of a group of modulation formats in which a RF bandwidth much wider than necessary is used to transmit an information signal so that a signal-to-noise improvement may be gained in the process. 86 Version 1.1 - 01/04/00 system gain The maximum path loss that the system can support for usable data transmission. W-OFDM Wide-band Orthogonal Frequency Division Multiplexing. A modulation scheme that encodes data inside a radio frequency signal. OFDM sends a high-speed signal concurrently on different frequencies. This allows for very efficient use of bandwidth and provides for robust communications that can transmit through interferences, such as occurring noise and stray and reflected signals, that can encumber radio communications.
