Command Set Summary Getting to Know Your Radio Trango Broadband Wireless — User Manual TrangoLINK Rev. A for F/W Ver. 1.0 Page 1 Chapter 1 Welcome! Your TrangoLINK-10 radio system provides the latest innovations in high speed fixed wireless broadband. TrangoLINK -10 is a point-to-point (PtP) system which provides network connectivity at speeds up to 10 Mbps with a range of 40 miles depending on antenna configuration. TrangoLINK-10 is unique in that it can operate in either the 5.8 GHz ISM band or the 5.3 GHz U-NII band. In this document and within the radio configuration itself, the designators of “ISM” and “U-NII” are used to distinguish between the two bands. The following table shows approximate maximum ranges (at recommended fade margins) achievable with the TrangoLINK-10 system using various antenna configurations. Longer ranges are achievable, but will result in lower fade margins. TrangoLINK-10 system consists of two types of radios: Master Units (MU) and Remote Units (RU). With careful channel planning, (and adequate spacing and shielding) network operators can co-locate up to 22 MUs at a single cell site. The MU and RU conform to maximum radiated power limits as established by the FCC. Getting to Know Your Radio Contents Each TrangoLINK-10 kit comes equipped with two radios, two power-over-Ethernet (PoE) J-Box, two AC adapters, a serial programming cable, and mounting hardware. Dual-polarized internal antennas are included within the Radomes of both the M5830S-MU and M5830S-RU.

Command Set Summary MU/RU Operational Overview Trango Broadband Wireless — User Manual TrangoLINK Rev. A for F/W Ver. 1.0 Page 2 Figure 0-2 Back of Radio Showing where MAC address can be Found Ethernet and Serial Ports At the bottom of the radio are two access ports: a twist-on weatherproof cable port for RJ-45 Ethernet (and PoE), and an access cover (with two screws) for RJ-11 serial port. Most configuration and management tasks can be performed through the Ethernet jack. The access cover also contains a small window which reveals three LEDs. These LEDs provide RF link-status information. These LEDs will be discussed later in this text. Antennas The M5830S-MU and M5830S-RU each include dual polarized antennas. The M5830S-MU-EXT and M5830S-RU-EXT are designed to work with FCC certified external patch style or dish antennas. All of these antennas can be electronically switched between horizontal (H) and vertical (V) polarization. MU/RU Operational Overview TrangoLINK MU is a sophisticated broadband wireless device which provides a host of comprehensive tools and functions. The MU typically resides at the managing end of the network and performs all management functions for the associated RU. In order to make a link more secure, prior to an RU communicating with a MU, the system administrator must first add the MAC address and ID number of the RU to the user database in the MU. When power is first applied to a properly installed RU, it will scan all the channels in its Scantable, searching for an MU. The RU will then stop on that channel and respond to the MU using maximum RF power. Before the MU can wirelessly connect to the RU, it must authenticate the RU by verifying the MAC address, and performing a ranging operation to the RU. Upon successfully locating and ranging the RU, the MU will adjust the RF transmit power in the RU based on the Target RSSI parameter in the MU. This process is referred to as “power leveling”. MUs and RUs look identical. The only way to tell them apart is by the model number printed on the backside product label. This label also contains the MAC ID of the radio as well as the serial #.

Command Set Summary Connections and Power Trango Broadband Wireless — User Manual TrangoLINK Rev. A for F/W Ver. 1.0 Page 3 Chapter 2 Getting Started First unpack your MU and RU. It is recommended to first provision and test the radios on the bench before deploying in the field. This is a particularly useful exercise to the novice user. Connections and Power Connection and powering of radios is the same for MUs and RUs. ?? Connect a Cat-5 (straight through) Ethernet cable (we recommend shielded twisted pair) between the ODU (out door unit) port of the J-box and the RJ-45 connector on the radio. Note that this cable will carry power over Ethernet (PoE). ?? If connecting to a COMPUTER, use a Cross-Over Ethernet cable from the NET port of the J-box to the computer’s Ethernet port. If connecting to a HUB, SWITCH, or ROUTER, use a Straight-Thru cable. ?? Plug the AC adapter into an AC outlet.

You are now ready to configure the radio via the Ethernet port. ? Note: If you can not access the radio management functions via the Ethernet port, it is possible that your PC is not set up with a properly routable subnet. If you forget the radio’s IP address, or for some other reason can not access the radio via the Ethernet port, use the Serial Programming cable (supplied with each TrangoLINK kit) and attach to RJ-11 located behind access cover on bottom of radio.
Command Set Summary Basic Configuration - Concepts and Tools Trango Broadband Wireless — User Manual TrangoLINK Rev. A for F/W Ver. 1.0 Page 4 Basic Configuration - Concepts and Tools The TrangoLINK-10 can be configured using either the Command Line Interface (CLI) or the Web Browser (HTTP) interface. Although both methods are comprehensive and powerful, the CLI method provides slightly more functionality. Both methods of radio configuration require an understanding of the concept of Operation Mode or “Opmode”. Opmode Concept Before logging on to a radio, it is important to understand the “opmode” concept of the TrangoLINK system. MUs and RUs can be in one of two Opmodes; OFF and ON. When in “OFF,” Opmode the radio is not transmitting, and it is not attempting to make a wireless connection. Alternatively, when in “ON,” opmode the radio is transmitting, and is attempting to make a wireless connection. Why is Opmode Important? TCP/IP management access (via the Ethernet port) to a Remote Unit is only possible in opmode “OFF”. However TCP/IP management of a Master Unit is possible in either opmode, On or Off. Also, certain functions, such as the site survey function and the RU RSSI function can only be performed while the radio is in opmode “OFF”. See Appendix – Command Set Reference for a complete listing of commands, and the appropriate opmode(s) for each command. ? Note: Factory Default opmode for both MUs and RUs is “ON”. Default opmode should be changed before radios are deployed. ? Note: Serial management (via the RJ-11 port) is possible on both MUs and RUs regardless of opmode.

Serial Mgmt. Command Line Interface Although most radio functions can be managed via the browser interface, the command line interface (CLI) does provide slightly more functionality. Logging on to the radio via command line interface is covered here briefly, but for a complete listing of all CLI commands, see the Appendix - Command Line Interface.
Command Set Summary Basic Configuration - Concepts and Tools Trango Broadband Wireless — User Manual TrangoLINK Rev. A for F/W Ver. 1.0 Page 5 Telnet Open a command prompt (DOS) session on your PC. Open a Telnet session by typing telnet [ip address of radio] Example: C:>telnet 192.168.100.100 ? Note: All Trango radios (MU and RU) come factory pre-configured with a default IP address 192.168.100.100. You will be greeted with current hardware and firmware information and prompted for a password. Type in the password and press enter. ? Note: The factory default password is trango. ? Note: If you can not telnet into the radio, check cable connections, ensure proper use of cross-over vs. straight-through cable, ensure PC’s subnet is routable to radio’s IP address. To Telnet to an RU, ensure that its opmode is “off”. Serial A Terminal Emulation program (such as HyperTerminal on the Windows operating system) can be used to access the radio’s CLI via the radio’s serial port which is located behind the RJ-11 access cover on the bottom of the radio. A serial programming cable has been provided with each MU for this purpose. The same cable may be used for Remote Units. The terminal program settings are 8-N-1, and Flow control: None. ? Note: To terminate a CLI session (Telnet or Serial) type the command logout. ? Note: Type help, or ? for a listing of all CLI commands. Type help <command> for the syntax of a particular command. Browser Interface The Web browser interface is a powerful and easy-to-use configuration and management tool. Its functionality is a subset of the commands available in the CLI. To use the browser interface – you must have the following: ?? An Ethernet connection between a PC and the radio ?? Setup your Ethernet PC connection to the subnet that is routable to the radio (default IP address=192.168.100.100) ?? A web browser (i.e. Microsoft Internet Explorer) In order to use the browser interface – simply connect the radio to a PC, and type the radio’s IP address into the web browser (i.e. Microsoft Internet Explorer). This will bring up a logon page.

Command Set Summary Procedure to Establish Wireless Link Trango Broadband Wireless — User Manual TrangoLINK Rev. A for F/W Ver. 1.0 Page 10 Chapter 3 Establishing a Wireless Link This section describes how to establish a wireless link between MU and RU, using the command line interface. Procedure to Establish Wireless Link In order to establish a wireless link, the following parameters must be set. 1. The Remote ID, the MAC ID of the RU, must be set in the MU. 2. The MU’s RF Channel and Polarization must exist in the RU’s channel scan table. 3. The Opmode of the MU is on. 4. The Opmode of the RU is on. 5. Adequate signal strength received at each radio. If all of these parameters are met, and if the MU and RU are within range - and properly aligned, the wireless link will automatically establish itself and Ethernet traffic will begin to pass between the radios. To ensure each of these parameters is met, perform the following steps: Master Unit Click the Configuration page link from any page in the Browser Interface. 1. Set IP, subnet, and gateway 2. Fill in the Remote ID with the MAC address of the RU 3. Set channel and polarization 4. Set default opmode to On 5. Update system setting flash memory by clicking Save and Activate Settings
Command Set Summary Basic Diagnostics Trango Broadband Wireless — User Manual TrangoLINK Rev. A for F/W Ver. 1.0 Page 11 At this point the MU will begin actively searching for the RU. Once the RU is detected, the authentication and association process will begin. The RU by default is ready to establish a link. Only the RF channel and polarization need to be chosen. By default it is on channel 1 with horizontal polarization. The default opmode is on. The RED LED on the bottom of the MU should be lit, indicating that the radio is in the on opmode and is radiating RF energy. Association Concept (MU to RU communications) TrangoLINK uses the concept of “association” to indicate that the MUs and RUs are communicating. If all parameters are properly set, the MU will begin actively searching for the RU. Once an active RU is detected, the authentication and association process will begin. ? Note: The RED LED on the bottom of the MU should be lit, indicating that the radio is in opmode “MU” and is radiating RF energy. ? Note: The amber light on the bottom of the RU indicates the relative signal strength (rssi) of the signal received. A steady light indicates a strong signal. A blinking light indicates weaker (although perhaps sufficient) signal strength. Basic Diagnostics In establishing and diagnosing the quality of the link, there several devices on the Link Control page that are especially useful.
Command Set Summary Basic Diagnostics Trango Broadband Wireless — User Manual TrangoLINK Rev. A for F/W Ver. 1.0 Page 12 Remote: The bottom left side of any page in the Browser Interface, under the heading Remote, shows the connection status of the RU. It will also show the Relative Signal Strength (RSSI) of the link RF Link Loopback Test: Sends 1600 byte packets to the RU at 50 millisecond intervals over the time specified and reports the success rate of the packets in bytes. Ranging/RSSI Test: Reports the distance of the link, and the RSSI from the MU to the RU. Power Level Remote Radios: Adjusts the transmit power of the RU to attempt to bring the MU RSSI as close as possible to the Target RSSI. Target RSSI can be adjusted on the Advanced Setup page.
Command Set Summary Site Selection Trango Broadband Wireless — User Manual TrangoLINK Rev. A for F/W Ver. 1.0 Page 13 Chapter 4 Deployment Once you are familiar with the basic operation of the radios you are ready for deployment in the field. The deployment process consists of the following steps: ?? Site Selection ?? Site survey at MU and RU sites. ?? MU installation ?? RU installation and antenna alignment ?? Link test Site Selection Proper site selection for your MU will help ensure a successful deployment. Site selection will depend on a wide variety of factors, but from the radio’s performance standpoint, please consider the following: ?? Path from MU to RU should provide unobstructed line-of-sight (LOS), thus it is advisable to place MU as high as possible on a tall building or tower ?? Ethernet cable limit is 100 meters from Ethernet device (router, switch) to radio ?? Radios should never be deployed without proper grounding ?? Carefully note the antenna coverage pattern for type of MURU deployed ?? Consider nearby sources of interference which could degrade radio performance. Mount radios as far from sources of interference as possible Site survey Both the MU and RU provide a powerful on-board site survey tool. This tool will tell you if there is interference present in the 5.8 GHz or 5.3 GHz band. In order to use the survey tool, the radio must be in opmode “OFF”. The survey can be performed for any specified amount of time (in seconds) and for either the horizontal or vertical polarization. Prior to performing the site survey, place the radio in the installation spot, and aim the radio in the desired direction. After the specified period, the results of this command will provide you with a listing of each channel in the band, the average signal received, and the maximum signal received during the survey period. In general you will be looking for frequencies with signal strength of –85 dBm or lower. If interference is present on various channels, it is recommended that you chose clean channels or alternate polarizations for your deployment. If it is not possible to use a clean channel/polarization combination, there are various methods available to mitigate the affects of interference. These methods include the use of the RFRX THRESHOLD settings, or the use of external shields on the MU. See Example on following page:
Command Set Summary Channel Planning Trango Broadband Wireless — User Manual TrangoLINK Rev. A for F/W Ver. 1.0 Page 14 Channel Planning For installations involving co-location of MU’s, channel planning is of paramount importance. For maximum MU co-location quantities, it is important to assign frequencies of maximum spacing and alternating polarizations for adjacent MUs. Use of the 5.3 spectrum U-NII band as well as the 5.8 spectrum ISM band will allow maximum co-location potential. For very dense deployments of multiple MUs, it may be necessary to use the optional MU Shielding kit in order to mitigate interference from nearby MUs.

See www.trangobroadband.com for additional information on channel planning schemes. Installation Once the site survey is completed, you are ready to install your radios. It is recommended that MUs be installed first. The reason for this is that the RU has a built-in RSSI tool which will help you properly aim the RU at the MU to achieve maximum signal strength. Mounting Hardware Both MUs and RUs are equipped with a universal mounting bracket which can be used for wall or pole installations. See diagram below for proper use of the mounting bracket.

The shield within the Cat-5 cable does not need to be grounded if the radio itself is grounded. It is important to consider that most Cat-5 cable will deteriorate over time if exposed to the weather (especially direct sunlight). It is recommended that installers place all Cat-5 cables inside conduit. Plastic or conduit is sufficient. If metal conduit is used, it is not necessary to use shielded Cat-5 cable. It is imperative that the radio be COMPLETELY SEALED at both the Ethernet port as well as the Serial Port access cover. The contracting weather-proofing clamp at the bottom of the Ethernet port must be securely tightened around the cable if conduit is not used. Proper sealing of the radio will ensure that moisture will not enter the enclosure of the radio. Without proper sealing, moisture may enter the radio and potentially cause damage which will not be covered under warranty. Proper mounting of the radio includes consideration for grounding. Please note that if the radio is attached to a metal pole which is earth-grounded, no other grounding is necessary. If the radio is not earth-grounded via the mounting bracket, you must attach a grounding wire to the grounding stud on the back of the radio as per the adjacent diagram.
Command Set Summary RU Installation and Antenna Alignment Trango Broadband Wireless — User Manual TrangoLINK Rev. A for F/W Ver. 1.0 Page 17 The cable ports are purposely located at the bottom of the radio to minimize the risk of water intrusion. Do not mount the radios upside down. ? Note: The J-Box is not a weatherized device and must be located either indoors or in a weather-protected cabinet. ? Note: It is important to provide strain relief and drip loop for STP Cat-5 cables. RU Installation and Antenna Alignment Once the MU is installed, and aligned in the correct general direction, it is time to install the RU. The hardware installation of the RU is identical to the MU, including considerations for line-of-sight, cable distances, cable type, weather sealing, and grounding. Once the RU is installed and aimed in the general direction of the MU, it is time to perform an RSSI test to determine the signal strength from the MU, and to precisely align the RU antenna for maximum signal strength. RU Antenna Alignment Procedure 1. Ensure MU is in opmode “ON” 2. Connect to the RU from the Ethernet side via the Browser Interface (while in opmode “OFF”) 3. Login and observe the RSSI indicator on the bottom left of the page. As you read the RSSI reading, move the antenna in the horizontal and vertical planes until the maximum RSSI reading is achieved. For short links you can expect an RSSI of –60 dBm or better. For longer links and RSSI of –75 dBm is acceptable. Any RSSI of less than –80 dBm may be too weak for the radios to reliably associate and pass data. 4. If it is not possible to receive an adequate RSSI reading, it may be necessary to reorient the MU (up/down, left/right), to increase the output power of the MU, or to move the RU to a location with better line-of-sight conditions to the MU. 5. Once you are satisfied with the RSSI reading, tighten down the RU in the optimum position. ? Note: The amber light on the bottom of the RU will also indicate RSSI according to the following parameters: RSSI< -80dBm not lit RSSI > -80dBm blinking. RSSI ? -65dBm solid. (blink rate increases with signal strength.) Link Test Ensure the RU’s default opmode is “ON” and that all configuration parameters are correct. Reboot the radio. Once the radio enters opmode “ON”, the authentication process will occur with the MU, and the two radios will begin to associate. From the MU side, use the Link Control page to assess the quality of the link. This was discussed earlier in the Basic Diagnostics section. If all tests show favorable results, the wireless link will automatically begin passing Ethernet traffic between the radios.
Command Set Summary RU Management Trango Broadband Wireless — User Manual TrangoLINK Rev. A for F/W Ver. 1.0 Page 18 Chapter 5 Management In the TrangoLINK system the MU controls most functions of its associated RU. For this reason it is important to consider that you will manage your TrangoLINK system primarily through the MU. Network management can be performed by three methods ?? Browser Interface ?? CLI Appendix – Command Set Reference ?? SNMP Manager Discussed in this section, below. RU Management Most management functions of the RU can be performed by issuing commands from the MU. Presented below are a few examples of these commands: Change the RUs IP, subnet, and gateway: re ipconfig <new ip> <new RUbnet> <new gateway> Example: re ipconfig 192.168.10.10 255.255.255.0 192.168.10.1 A complete description of these commands and many others can be found in Appendix – Command Set Summary. Managing MU from RU side of Network As a security feature, TrangoLINK was designed to prevent users on the RU side of the network from accessing the MU via telnet or HTTP interface. If it is necessary for network administrators to access a MU from the RU side of the network the user must first telnet into a router, or similar device, located behind the MU. Then telnet from the router into the MU. SNMP TrangoLINK supports Simple Network Management Protocol (SNMP) for network management. Network management consists of the following 4 categories: configuration, accounting, alarm, monitoring, and control. These capabilities allow the network operator to provide superior services through higher network availability and integrated accounting system. For more information on SNMP and its uses, you can visit http://www.faqs.org/faqs/snmp-faq/. The Trango SNMP solution supports MIB-II (system only) and the Trango proprietary Management Information Base (MIB). The SNMP agent resides on the MU ONLY. It gathers health and status, performance statistics from all RUs locally, then responds back to the SNMP manager upon request. Users interested in using the SNMP functionality should review the entire TrangoLINK MIB for a complete understanding of its features. The following is an overview of a few of the more commonly used SNMP objects in the TrangoLINK system. Objects for Monitoring and Control su Bandwidth Monitoring ?? suEthRxAvgThroughputLog – Average payload data throughput (in Kbits/sec) received on the Ethernet port over the period specified by suStatisticsSamplePeriod (1 ~ 60 minutes). ?? suEthTxAvgThroughputLog - Average payload data throughput (in Kbits/sec) transmitted on the Ethernet port over the period specified by suStatisticsSamplePeriod (1 ~ 60 minutes). ?? suRfRxAvgThroughputLog - Average payload data throughput (in Kbits/sec) received on the RF link over the period specified by suStatisticsSamplePeriod (1 ~ 60 minutes). ?? suRfTxAvgThroughputLog - Average payload data throughput (in Kbits/sec) transmitted on the RF link over the period specified by suStatisticsSamplePeriod (1 ~ 60 minutes). ?? suRfInOctets – Number of octets of payload transmitted from MU’s RF port. ?? suRfOutOctets – Number of octets of payload received from MU’s RF port.

Cold start – when SNMP agent starts running ?? Link Up – when the MU enters opmode “MU” ?? Link Down – when the MU reboots ?? SU Link Up – when su associates to the MU ?? SU Link Down – when RU disassociates from the MU ?? “MU” opmode Failure – when MU fails to enter opmode “MU” MU and RU Control – SNMP also provides several control capabilities. The majority of the features available on the CLI are also available via SNMP. Here are a few of these features: ?? Add/delete RUbscriber ?? Change channel ?? Set power ?? Set radio sensitivity Review the Trango MIB (trango_P5830Sap_1p0.mib) for the complete listing of MIB Objects. SNMP Setup Trango Broadband provides only the MIB portion of the SNMP Management system. The radios act as individual agents, and it is up the user to provide an SNMP Manager software from a third party vendor. Below is an example of the setup process for SNMPc from Castle Rock™. 1. Unzip trangopkg.zip file to a local temporary directory. 2. Go to your local temporary directory, you will see 4 files shown below. a. trango_P5830Sap_1p0.mib – M5800S AP MIB file b. trango.ico – P5830S AP icon c. autoico.txt – instruction file (Selects Trango icon automatically during initial set-up.) 3. Copy trango_P5830Sap_1p0.mib file to C:\Program Files\SNMPc Network Manager\mibfiles 4. Copy autoico.txt file to C:\Program Files\SNMPc Network Manager\mibfiles 5. Copy trango.ico file to C:\Program Files\SNMPc Network Manager\bitmaps 6. The MIB needs to be compiled into the SNMPc database By default, the Read Community is set to “public”, and Write Community is set to “private” in the MU. The Trap Community is “SNMP_trap”. The manager needs to have the same settings in order to communicate with the MU successfully. ? Note: The Trap Community can not be set via HTTP, and CLI. To send traps from the MU, set the following: ?? trap destination IP (Trango MIB object trapconfig–trapconfigInfo) ?? trap community string (Trango MIB object trapconfig–aptrpTable-AptrpEntry) ?? enable each trap (Trango MIB object traponfig–aptrpTable-AptrpEntry)

A for F/W Ver. 1.0 Page 25 Chapter 7 Glossary A Antenna Gain The gain of an antenna is a measure of the antenna’s ability to direct or focus radio energy over a region of space. High gain antennas have a more focused radiation pattern in a specific direction. AP Access Point. A wireless LAN data transceiver that uses radio waves to connect a wired network with wireless stations. It is the Point in a Point-to-Multipoint system. AP-Centric The Access5830 is a Point to Multipoint system with the access point being the single point and Subscriber Units being the multi-points. It is sometimes referred to as a cell system. See also Base Station. Associated A station is configured properly to allow it to wirelessly communicate with an Access Point. B Base Station Broadcast Packet A single data message (packet) sent to all addresses on the same subnet. C CCK Complementary code keying. A modulation technique used by IEEE 802.11b-compliant wireless LANs for transmission at 5.5 and 11 Mbps. Cell The area of radio range or coverage in which the wireless devices can communicate with the base station. The size of the cell depends upon the speed of the transmission, the type of antenna used, and the physical environment, as well as other factors. D Data Rates The range of data transmission rates supported by a device. Data rates are measured in megabits per second (Mbps). dBi A ratio of decibels to an isotropic antenna that is commonly used to measure antenna gain. The greater the dBi value, the higher the gain, and the more acute the angle of coverage. DHCP Dynamic host configuration protocol. A protocol available with many operating systems that automatically issues IP addresses within a specified range to devices on the network. The device retains the assigned address for a specific administrator-defined period. Domain Name The text name that refers to a grouping of networks or network resources based on organization-type or geography; for example: name.com— commercial; name.edu— educational; name.gov— government; ISPname.net— network provider (such as an ISP); name.ar— Argentina; name.au— Australia; and so on. DNS Domain Name Server. A server that translates text names into IP addresses. The server maintains a database of host alphanumeric names and their corresponding IP addresses. DSSS Direct sequence spread spectrum. A type of spread spectrum radio transmission that spreads its signal continuously over a wide frequency band. E Ethernet The most widely used wired local area network. Ethernet uses carrier sense multiple access (CSMA) to allow computers to share a network and operates at 10, 100, or 1000 Mbps, depending on the physical layer used. EIRP Effective Isotropic Radiated Power F File Server A repository for files so that a local area network can share files, mail, and programs. Firmware Software that is programmed on a memory chip. G Gateway A device that connects two otherwise incompatible networks together. GHz Gigahertz. One billion cycles per second. A unit of measure for frequency.
