Description About W-OFDM The Libra system uses Wi-LAN’s patented Wide-band Orthogonal Frequency Division Multiplexing (W-OFDM) technology to process, transmit and receive data in parallel fashion over the air. WOFDM divides a wide RF frequency band into several subchannels that work together to deliver data, similar to splitting a road into several lanes that together can handle more traffic than a single lane.
About Point-to-Multi-Point (P-MP) Systems About Point-to-Multi-Point (P-MP) Systems Two kinds of equipment are required for a wireless P-MP link: Access Point (AP) equipment and Customer Premise Equipment (CPE). AP equipment is located at the service provider’s site and CPE equipment is located at the customer’s site. The LIBRA 5800 P-MP product is available as an AP, a CPE with integrated 23 dBi antenna or an LCPE for connection to higher gain external antennas.
Description The Access Point is responsible for any CPE data management functions. The Libra 5800 AP consists of three parts: 1) AP radio unit, 2) Ethernet Power Inserter with CAT-5 cable (bought separately) and weatherproofing kit (included), and 3) the External Antenna and cable (both bought separately). • LIBRA 5800 AP– The AP is the main piece of radio equipment.

Configuration Radio Configuration You can configure radio settings such as RF station IDs, Sector ID, Synchronization ID, center frequencies transmit power and Base Station modulation type with the Radio Configuration menu. Setting the RF Station ID (P-MP Only) Each AP, CPE or LCPE unit requires a unique RF Station ID to identify it on the network. Every unit must have a unique RF Station ID. No two units in a single sector (i.e. one controlled by a single AP) may have the same ID.
Radio Configuration Setting the Sector ID Each Libra unit can have a Sector ID to identify its AP within the cell on the network. This prevents Libra units from connecting to different APs which may have the same Center Frequency. ➧ To set the Sector ID 1. From the Main System Menu, select Radio Configuration and press Enter. The Radio Configuration menu appears. Radio Configuration OFDM Station Type RF Station Id [1..2047] Sector Id [0..31] Synchronization Id [0..
Configuration Setting the Synchronization ID Because of OFDM’s superior multipath performance it is possible for the CPE to falsely synchronize on an AP from a different sector operating at the same frequency. In order to avoid this type of error, the APs and CPEs of each sector can have one of two possible OFDM synchronization patterns. These patterns are orthogonal, thus a CPE with a given Synchronization ID will never synch to an AP with the other synch.
Radio Configuration The center frequency is a frequency located in the middle of each set of transmit and receive channels and it defines the group of frequencies situated around it. ➧ To set the RF Center Frequency 1. Move the cursor to the Set RF Center Frequency field and press Enter. The entry field is highlighted. 2. Enter the frequency value assigned to this unit in kHz and press enter to effect the changes. The unit does not require rebooting for this change to become effective.
Configuration Setting Tx Power The transmitter power setting enables you to adjust the strength of the transmit signal sent from the Libra unit to the antenna. The range is -3 dBm to 17 dBm. ➧ To set the Tx power 1. From the Main System Menu, select Radio Configuration and press Enter. The Radio Configuration menu appears. Radio Configuration OFDM Station Type RF Station Id [1..2047] Sector Id [0..31] Synchronization Id [0..
Radio Configuration Setting the Modulation Type The OFDM Modulation Type can be selected from among the following possible values: "QAM 16", "QPSK" and "BPSK". The selected type will be added to the next superframe transmitted. ➧ To set the Modulation Type 1. From the Main System Menu, select Radio Configuration and press Enter. The Radio Configuration menu appears. Radio Configuration OFDM Station Type RF Station Id [1..2047] Sector Id [0..31] Synchronization Id [0..
Configuration Remote Station Configuration Menu (P-MP Only) This menu only appears on the Libra 5800 when set up as an AP. When setup as a P-P unit there is only one unit to poll with an id of zero so this menu is not needed. It displays a portion of a larger table. The table row order determines the polling sequence of the units. Changes to the table take effect immediately. The table cannot contain zeros between valid radio ids.
Remote Station Configuration Menu (P-MP Only) Field Name Type Comments Radio Id Variable Integer (1..2048) Identifies a unit to be polled. Values correspond to the RF Station Id field in the Radio Configuration Menu (see page 28). A given ID may be listed more than once, in which case that unit is polled more than once in a single polling cycle. A value of zero (an invalid RF Station ID) means the table entry is not polled.
Configuration IP/MBR Filter Configuration IP filters help ensure that only valid subscribers use the wireless link. IP address filters are actually tables that contain lists of IP addresses and masks on the local Ethernet. If an address is listed in the table, the CPE will pass data packets to and from it. If the address is not defined by one of the filters, the unit will not pass data packets to it or from it. Air IP Address Filter Table xxx.xx.xx.x xxx.xx.xx.x IP xxx.xx.xx.

Troubleshooting Preventative maintenance Administering and maintaining your system properly can prevent many problems and alert you to minor problems before they become serious. Some recommendations follow. • Measure and document system performance at the time of the original installation. • Change menu passwords so that only authorized people can reconfigure the system. See Setting Menu Passwords, page 53. • Maintain the integrity of the system design when adding to or changing a system.
Troubleshooting Troubleshooting areas There are five areas to keep in mind when troubleshooting: 1. Network integrity: The continued performance and reliability of a network depend upon maintaining the integrity of the network. If you change a network’s design, you will affect its operation. Be aware of recent changes to your network. 2. Quality of RF links: Data communication depends first on good RF links.

Appendix B: SNMP MIB Overview Simple Network Management Protocol (SNMP) Management Information Base (MIB) and SNMP Agent software come with each BWS unit. This software lets you configure, monitor, and control units via the Ethernet or air. This lets you easily configure units in remote and hard-to-reach locations, and network managers can avoid or reduce downtime by monitoring network throughput, packet collision rates, and interference.
Appendix B: SNMP MIB Obtaining SNMP Software SNMP network management software is available commercially or as shareware. For instance, you can download a free evaluation copy from www. mg-soft.com. You also require a proprietary MIB file, which you can download from www. wi-lan.com or obtain by contacting Wi-LAN’s Technical Assistance Center. After you download the MIB file, you must compile it with the SNMP compiler.

Appendix D: Linktest and Link Statistics Overview You can test the ability of a link to send and receive data with Linktest. Linktest can be run from an AP or CPE/LCPE in P-MP or from either base or remote in P-P systems. You can also view performance statistics with the MAC Layer Statistics menu.
Appendix D: Linktest and Link Statistics The transmitting (local) unit generates pseudo-random packets of data that it sends to the receiving (remote) unit at the other end of the link. The remote unit compares the packets and measures the BER (bit error rate), RSSI, Fade Margin, Forward Error Correction (FEC) and other statistics. It sends those statistics and the original data back to the local unit. The local unit reads the data and displays the accumulated statistics.
Performing a Linktest Symbol variation within the configured accuracy. The default is 16, meaning the symbol changes every 781 frames, the equivalent of 1E6 bits. A higher var value results in a slower test with more reliable BER statistics. Linktest takes only multiples of 16. For example, if is set to 32, the symbol changes every 390 frames. If it is set to 30, it still changes every 390 frames. If is set to 16, and is set to 7, then the symbol will change every 7,810 frames.
Appendix D: Linktest and Link Statistics R Statistics measured at the Linktest remote L Statistics measured at the Linktest local RSSI Received signal strength indicator. A good value is -60 to -65. The receive sensitivity is -75 for the CPE and -78 for the AP Fade Margin Number of dB by which the received signal strength exceeds the minimum receiver sensitivity. A good value is 15, assuming the RSSI = -60. The higher the fade margin the better.
Appendix E: Bench Configuration Testing Overview This chapter explains how to assemble, configure and test Libra equipment to familiarize yourself with it or to help debug it should problems occur. Equipment will be tested in pairs consisting of an AP and a CPE for a P-MP system or two P-P units (RD’s or ER’s) in a controlled environment such as a lab. Detailed information about configuring Libra units can be found in Configuration, page 27.
Appendix E: Bench Configuration Testing Tools and equipment You will need the following tools and equipment to perform a bench test. 3/16” nut driver Cables: CAT-5 / Power cables with RJ-45 connector (not supplied with units). PC or PDA with a terminal emulation software such as HyperTerminal and network software (ftp and ping) RS-232 cable to connect the PC or PDA to the serial port of the Libra.

Appendix E: Bench Configuration Testing Assembling the Libra Units Once you have assembled either one AP and one CPE (for P-MP) or a base and remote (for P-P) for familiarization, you may use the AP or the Base to bench test any CPEs or remotes that may have problems in the field. This setup can also be used to pre-configure units before field installation or to pre-test units.
Configuring the units Configuring the units This section describes how to set intitial AP and CPE (for P-MP) parameters or base and remote (for P-P) parameters so you can perform bench tests. See Configuration, page 27 for detailed instructions about setting parameters. ➧ Hookup to Configure the Libra 1.
Appendix E: Bench Configuration Testing • Set the RF Station ID as configured in the AP polling list • Set RF Center Frequencies. Choose the same frequency as for the AP configuration. • Select the Synch ID to be the same as that for the AP • Select the Sector ID to be the same as that for the AP • Set IP Address Configuration • Select the Transmit Power Note: In a lab environment the units are physically closely located.
Testing the units Testing the units Test the units to make sure that a basic RF link exists and data can be sent over it. In this section you will complete the following tasks. A) Test the link with Linktest B) Perform some simple network tests Testing the RF link with Linktest In this step, you will test the basic RF link with Linktest. Linktest verifies that a link can send and receive test data. ➧ To test the RF link with Linktest NOTE:In a lab environment the units are physically closely located.

View the MAC Layer Statistics screen at the configuration PC while using ftp to transfer a large file from a PC on the AP side to a PC on the CPE side.
Glossary A absorption Antennas mounted too close to “soft” objects, such as trees, may experience a reduction in signal strength due to absorption. Absorption is most often encountered in antennas installed during fall or winter. The problem does not start until the spring, when leaves appear. Access Hub A group of APs, each serving a group of CPEs. Also called a cell site. Access Point The base station of the BWS network.
Glossary ASCII American Standard Code for Information Interchange. A system used by personal computers to convert letters, numbers and symbols into binary notation. Automatic Frequency Control A method by which the CPEs stayed tuned to the correct frequency for communicating with the AP, despite frequency variations caused by the hardware. attenuation Any loss in signal strength, due to resistance, absorption, capacitance, or any characteristic of the medium or design of the system.
CPE Customer Premise Equipment – the remote or subscriber unit in the Wi-LAN Broadband Wireless Access System. co-location Placing antennas in the same place. One rooftop may host up to six antennas, each attached to a different AP ODU and IDU. coaxial cable A type of wire that has an inner conductor surrounded by an outer conductor. The outer conductor also serves as an electrical shield. collision A collision occurs when two devices send signals over the same medium at the same frequency at the same time.
Glossary dBi dBi is antenna gain referenced to an isotropic radiator. This a theoretical antenna that radiates equally in all directions, like the sun. Wi-LAN references antenna gain in dBi. The conversion factor is 0 dBd = 2.14 dBi dBm A power measurement with respect to one milliwatt. This is an absolute measure of power rather than a relative measure such as a gain or a loss. Default Gateway IP Address This is the address of the gateway from the wireless network to the wired one.
ESD Electrostatic Discharge. Caused by static electricity. ESD Protection should be used to protect electronic components from damage. F fade margin The amount by which the system gain plus the total antenna gain exceed the path loss is called the fade margin. The fade margin is the number of dB that the received signal strength exceeds the minimum receiver sensitivity. FEC Forward Error Correction. A method of correcting data errors without retransmission.
Glossary G Gain The ability of a device to amplify a signal. Gain is the ratio of output power divided by input power, usually expressed in decibels (dB). Gain can also be measured as an absolute value, referenced to an input signal of one milliwatt (dBm). For antennas, gain measures the ability of an antenna to focus a signal and is expressed in dBd (half-wave dipole reference) or dBi (isotropic radiator reference). GPS Global Positioning System.
L LAN A localized network linking computers, servers, printers and other peripheral devices. Typical configuration is within buildings or between closely situated buildings. Line of Sight (LOS): Free Space An unobstructed straight line between two transmitting devices. The transmission path is not established by nor dependent upon reflection, refraction or diffraction. As long as 60 per cent of the first Fresnel zone is clear, then it may be considered almost equivalent to LOS transmission.
Glossary N Near Line of Sight (NrLOS): Suburban NrLOS is a visually-obstructed line of sight between two transmitting devices but a straight line can still be drawn between them. Any combination of reflection, refraction and diffraction on a direct ray between the transmitter and receiver may have occurred. Non Line of Sight (NLOS): Dense Urban No line can be drawn between two transmitting devices. Total visual blockage has occurred between the transmitting and receiving devices.
Orthogonal An adjective that refers to the way the many carrier waves in a W-OFDM system affect each other. The carriers are spaced in such a way that the center frequency of each signal lies in the null spot of its neighbors. This minimizes interference. overhead Anything that reduces the payload capacity of a system is overhead, even if it is useful. Link monitor data determines transmission statistics, but it reduces the message-carrying capacity of the system and is considered overhead.
Glossary Q QAM Quadrature Amplitude Modulation. A kind of modulation that varies signal amplitude. R Reed-Solomon A way of accomplishing Forward Error Correction. Reed-Solomon describes a data block in such a way that errors in the data block can be detected and repaired without retransmission. remote unit A unit that can communicate with a base station or other remote units. A remote unit forms a wireless link between a network segment and a base station. CPEs are the remote units in the BWS system.
SNMP Simple Network Management Protocol. A protocol used 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 exchanging management information in a TCP/IP-based Internet environment. SNMP NMS Trap IP Address This is the address to which all the alarms and event messages are sent.
Glossary VT 100 A terminal emulation system. W WAN Wide Area Network. A network covering a larger area than a Metropolitan Area Network which covers a city. Wind loading A problem of antenna installation and operation. W-OFDM Wideband Orthogonal Frequency Division Multiplexing. A variation on the OFDM modulation scheme that allows greater range with less power, higher data rates, less distortion and greater immunity to interference.
