Trango Broadband Wireless — M900S User Manual Rev. 1A page iv Introduction Section 1 Introduction Your Trango Broadband M900S radio system provides a reliable and robust means to deliver broadband access and wireless Ethernet connectivity to a wide geographic region. This section will familiarize you with basic operational concepts as well as an overview of the hardware and the various components of the M900S system. Overview The M900S is a highly versatile and cost effective outdoor point-to-multipoint solution for wireless broadband service providers enterprise connectivity applications. The M900S delivers 3 Mbps over the air, and operates in the 900 MHz ISM band. Each radio includes an integrated built-in dual polarized (horizontal and vertical) antenna as well as a connector for the attachment of an external antenna such as a yagi or an omni style antenna The M900S system is classified as a Layer 2 multi-point bridge. Authentication of SUs is performed using a secure, proprietary method at the MAC level, and thus all forms of Ethernet traffic and unlimited IP addresses will pass seamlessly over the system. There is no limitation on the number of IP addresses or hardware devices that an individual SU may have physically connected to an M900S radio. Both APs and SUs can be easily configured and managed (either locally or remotely) through built in serial and Ethernet interfaces, along with a web browser provisioning tool for quick set up and deployment. The M900S radios are powered using "Power over Ethernet" for ease and low-cost installation. Both APs and SUs feature a handy "site survey" tool to check for interference. The M900S system consists of two types of radios: Access Points (AP) and Subscriber Units (SU). The AP unit acts as a hub in a star configuration wireless multipoint network supporting up to 126 subscriber units. The AP delivers wireless broadband service (Ethernet connectivity) to one or more SUs according to a proprietary adaptive dynamic polling algorithm called SMARTPolling™ Network operators can co-locate multiple APs at a single cell site, thus increasing the aggregate throughput available at each wireless point of presence (POP). Figure 1-1 Typical Point-to-Multipoint Deployment The M900S AP provides a host of comprehensive tools and functions. The AP typically resides at the center of the point-to-multipoint (PMP) network and performs all management functions including the allocation of bandwidth for all associated SUs. SmartPolling™ Overview One of the major advantages of the M900S system is the ability of the AP to handle multiple SU connections and share the 3 Mbps data throughput very efficiently. Bandwidth allocation is managed by the AP’s SMARTPolling algorithm according to provisioning rules set up by the system administrator. The AP polls each SU in a round robin format to determine if the SU has data to transfer. The SU only transmits the data “upstream” to the AP when the AP gives authorization via a “transmit grant”. The SU parses every “downstream” data packet from the AP and identifies packets intended for it. In order for an SU to communicate with an AP, the system administrator must first add the MAC address and ID number of the SU to the user database in the AP. The SmartPolling algorithm will poll active SUs more often thus making the most efficient use of the 3 Mbps bandwidth. Several other parameters are considered in the SmartPolling algorithm including Committed Information Rate (CIR), Maximum Information Rate (MIR), and Priority Setting. Trango Broadband Wireless — User Manual Access5830 Rev. D Page 1 Introduction Each of the above parameters are set in the AP by the system administrator and cannot be controlled at the SU. These parameters will be covered in greater detail later in this text. When power is first applied to a properly installed SU, it will scan all available channels, searching for an AP with matching Base ID and MAC in its SU Database. The SU will then stop on that channel and respond to the AP using maximum RF power. Before the AP can add the SU to the polling list, it must authenticate the SU by verifying the MAC address, and performing a ranging operation to the SU. Upon successfully locating and ranging the SU, the AP will then add the SU to the normal polling list and, it will adjust the RF transmit power in the SU based on the Target RSSI parameter in the AP. This process is referred to as “power leveling”. Trango Broadband Wireless — User Manual Access5830 Rev. D Page 2 Hardware Overview Section 2 Hardware Overview This section provides detail about each radio in the M900S family. Each radio in the M900S family includes built-in, electronically switchable dual-polarized antennas as well as a reverse polarity SMA connector for the attachment of an external antenna. All units are designed for outdoor installation, powered by Power-over-Ethernet (POE) for ease of installation. The M900S Access Point, as well as the M900S subscriber units provide channels of operation within the 900 MHz ISM band which spans from 902 MHz to 928 MHz. Default channel spacing is 6 MHz, allowing for 4 non-overlapping channels. M900S AP and SU Hardware Components Each radio comes equipped with the radio itself, a power-over-Ethernet (PoE) J-Box, an AC adapter, and mounting hardware. The Access5830 AP (part #M900S-AP) also includes a serial programming cable. Figure -2-1 Basic Components of an M900S Radio Radio (AP or SU) antenna Power Supply (120 VAC-20 VDC) J Box (Power over Ethernet Injector) Serial Programming Cable (AP Only) Figure 2-2 Bottom of Radio picture of bottom of radio w/label for Ethernet Port and LED cover At the bottom of the M900S are two access ports: a twist-on weatherproof cable port for RJ-45 Ethernet (and PoE), and a translucent access cover plug over the unit’s diagnostic LEDs and reset button. The LEDs will be discussed later in this text. The radio’s model number and FCC ID, MAC ID, and Serial # are located on the side of the radio. Trango Broadband Wireless — User Manual Access5830 Rev.

These limits are Figure 2-4 Side of Radio & Location of Reverse Polarity SMA Connector Insert picture of side of radio showing rev. polarity SMA Connector Section 3 Getting Started This section explains how to power your radios, establish TCP/IP connectivity to the radios, as well as how to access the HTTP browser and the command line interfaces. Connections and Power Connection and powering of radios is the same for APs and SUs. ?? 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. Trango Broadband Wireless — User Manual Access5830 Rev. D Page 4 Getting Started Figure 3-1 Wiring Diagram NETWORK OR COMPUTER INDICATES POWER TO RADIO INDICATES POWER TO J BOX CAT-5 USE STRAIGHT-THRU CABLE IF TO HUB, SWITCH OR ROUTER CAT-5 STRAIGHT-THRU CABLE USE CROSS-OVER CABLE IF TO COMPUTER AC POWER 20 VOLT POWER SUPPLY POWER OVER ETHERNET J BOX Both green LEDs on the J-box should be lit, indicating power is present at the J-box as well as the radio. You are now ready to configure the radio via the Ethernet port. Opmode and Radio Management Concepts Proper connections to the radios and careful IP/routing & planning will enable the network administrator to access and manage the radios remotely over the network. Radio management over TCP/IP can be performed from PCs connected to the Ethernet side of each radio. Further, PCs connected to the AP can manage the SU over their wireless connection; and, PCs connected to the SU can manage the AP, provided that switch 7 (TCP/IP for SU) is enabled at the AP. Switches will be covered later in this text. Opmode To fully understand radio management for the Access5830 system, it is important to be familiar with the concept of operation mode or “opmode”. APs can be in one of two opmodes; “OFF” opmode, or “AP” opmode. When in “OFF” opmode, the radio is not transmitting, and it is not attempting to associate with SUs. Alternatively, when in “AP” opmode, the radio is transmitting, and is attempting to associate with SUs. Similarly, SUs have two opmodes: “SU” opmode or “OFF” opmode. Certain functions, such as the site survey function and the SU RSSI function can only be performed while the radio is in opmode “OFF”. See Appendix D – Command Set Reference for a complete listing of commands, and the appropriate opmode(s) for each command. Switch Settings M900S firmware includes several “switches” which are used to set certain operational parameters of the radios. Switch settings can be changed via the HTTP browser interface or the Command Line Interface. For purposes of radio TCP/IP management, the following three switches are important: SU Switch 2 - TCP/IP access to SU from AP side of network requires that the SU’s switch 2 (SW 2 – TCP/IP for AP) be “ON”. Default setting for SW 2 (from factory) is “ON”. Trango Broadband Wireless — User Manual Access5830 Rev. D Page 5 Getting Started AP and SU Switch 5 – In order to utilize the radio’s HTTP Browser interface, switch 5 (SW 5) must be “ON”. Default seting for SW 5 (from factory) is “ON”. SU Switch 6 - TCP/IP access direct to SU from SU side of network requires that switch 6 (SW 6) be “ON”. Default setting for SW 6 (from factory) is “ON”. If SW 6 is off, TCP/IP access to SU from SU the SU side of the network is possible only if SU’s opmode is OFF. AP Switch 5 – TCP/IP access to AP from SU side of network requires that the AP’s switch 7 (SW 7 – TCP/IP for SU) be “ON”. Default setting for SW 7 (from factory) is “OFF”. Browser Interface The HTTP browser interface is a powerful and easy-to-use configuration and management tool. The pages originate from the radio itself, so no additional software is needed on the managing PC other than a web browser. The browser interface’s functionality is a subset of the commands available in the command line interface (CLI). To use the browser interface – the following must be present: ?? An Ethernet connection between a PC and the radio ?? Ethernet PC connection with 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. ? Note: Most pages are similar for Access Points and Subscriber Units. When there are significant differences, both are included in this text. With each page there is a brief description of the major features. For more discussion on any feature see the Command Set Reference, or click the Help hyperlink. Figure 3-2 Browser Interface Login Page Type the password (default trango) and continue. This will bring up the radio’s system information page. Trango Broadband Wireless — User Manual Access5830 Rev. D Page 6 Getting Started Figure 3-3 Web Browser System Information Page Figure 2-3 shows system information for an Access Point. Basic system information for a subscriber unit is similar and is covered in detail later in this text. The following describes the primary features and pages of the HTTP Browser interface: Navigation Column: Each page features a navigation column which runs along the left-hand side of the page. The model number of the radio is listed at the top of the navigation column. On the bottom of the navigation column is the Current Status of the radio including its Base ID, current Opmode, channel, antenna selection, and frequency. The navigation column also features links to each of the following pages: System Information: This page shows most of the basic configuration parameters of the radio. It is the first page shown after login. Configuration: The essential parameters, such as Base ID, channel and polarization are set here. Advanced Setup: The advanced RF parameters, such as transmit power are set here. Site Survey: From here, in Opmode Off, the user can conduct a spectrum analysis. Subscriber Database: This is the page for defining which SUs can associate to the AP. Link Control: This page shows which SUs are associated. This page also provides several tools for evaluating the quality of the wireless link. Command Console: From this page, the user can run any console command which is not interactive (i.e. ipconfig). The results are reported back via HTTP screen. For a complete list of console commands, type "help" or “?” in the entry field. Trango Broadband Wireless — User Manual Access5830 Rev. D Page 7 Getting Started Logout: This link will end the current HTTP session with the radio. Help: The Browser Interface features useful Help pages which explain all listed parameters. To access the help pages click on the Help link. For a complete description on use of the Browser Interface, see Appendix A. Command Line Interface Although most radio functions can be managed via the browser interface, the command line interface (CLI) does provide slightly more functionality. The CLI can be accessed through Telnet. 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 All Trango radios (AP and SU) come factory pre-configured with a default IP address 192.168.100.100. In Telnet, you will be greeted with current hardware and firmware information and prompted for a password. Type in the password and press enter. The factory default password is trango. To terminate a CLI session (Telnet or Serial) type the command logout. Note: Type help, or ? for a listing of all CLI commands. Type helpfor the syntax of a particular command. The majority of the CLI commands will be covered throughout this text as well as in Appendix B on the Command Set Reference. Troubleshooting If you can not telnet into the radio or open an HTTP browser session, check cable connections, ensure proper use of cross-over vs. straight-through cable, ensure PC’s subnet is routable to radio’s IP address. If you can still not access the radio’s management interfaces, consult the troubleshooting guide which is available at www.trangobroadband.com in the Technical Support area of the website. Reset Button M900S APs and SUs feature a reset button (located under the translucent plug which can be pressed with a small object such as a paper clip. Pressing the reset button will reset all of the radio’s parameters (including IP address and passwords) to factory default 192.168.100.100 and password trango. The reset button can be useful if you forget or are unsure of the radio’s IP address/password. Trango Broadband Wireless — User Manual Access5830 Rev. D Page 8 Basic Configuration via Browser Interface Section 4 Basic Configuration via Browser Interface This section describes a few more basic concepts and how to establish a basic wireless link between AP and SU, using the Browser (HTTP) Interface . This section is written to address only the most basic steps in establishing a link in the lab, or a bench-top environment. It is highly recommended to read the other sections of this manual to gain an understanding of all important configuration parameters and procedures prior to deploying any wireless equipment. In this section you will: ?? Learn about AP and SU Basic Configuration Screens and Parameters ?? Populate Access Point’s Subscriber Unit Data Bases (SUDB) with at least one SU. ?? Configure Other Basic AP Parameters ?? Configure Basic SU Parameters ?? Establish a Wireless Link ?? Evaluate Link Quality The Access5830 uses the concept of “association” to indicate that the APs and SUs are communicating. If all parameters are properly set, the AP will begin actively searching for the SUs in its SU database (SUDB). Once an active SU is detected, the authentication and association process will begin. Essentials to Establish a Wireless Link with M900S Series Radios ?? Base ID in AP and SU must match ?? MAC Address of SU must match an entry in the subscriber unit database (SUDB) ?? AP must be in Opmode “AP” ?? SU must be in Opmode “SU” ?? Adequate signal strength must be received at each radio If all of these parameters are met, and if the AP and SU are within range - and properly aligned, the wireless link will automatically establish itself and Ethernet traffic will begin to pass between the radios. Note: This section utilizes the Browser Interface as the configuration tool. For the equivalent CLI commands, see Section 5. Configuring AP Subscriber Unit Database Prior to establishing a wireless link, the user must configure the Subscriber Unit Database (SUDB) in the AP with each SU’s MAC address and related settings. The subscriber unit database includes detailed information about each SU. The user uses the Subscriber Database page to add, modify, and delete SUs. The key information for each SU includes the following: SU ID: User Definable subscriber unit ID (1…8190) TYPE: PR Priority or REG Regular. Priority SUs are favored in the dynamic polling process and thus respond with less latency than regular SUs. Group: SU to SU Group # (1..F in hex) for SU to SU communications. Only SUs with same SU to SU group # may communicate with each another. CIR UP: Committed Information Rate from SU to AP. Minimum upstream rate (measured in Kbps) at which the SU will attempt to deliver bandwidth to the AP. Maximum setting is 3000. CIR DOWN: Committed Information Rate from AP to SU. Minimum rate (measured in Kbps) at which the AP will attempt to deliver bandwidth to this SU. Maximum setting is 3000. MIR UP: Maximum Information Rate from SU to AP. Maximum upstream rate (measured in Kbps) at which the SU will attempt to deliver bandwidth to the AP. Maximum setting is 3000. MIR UP: Maximum Information Rate from AP to SU. Maximum rate (measured in Kbps) at which the AP will attempt to deliver bandwidth to this SU. Maximum setting is 3000. DEVICE ID: MAC address of the SU. The MAC address and BASE ID are the basis for authentication with the AP. Trango Broadband Wireless — User Manual Access5830 Rev. D Page 9 Basic Configuration via Browser Interface . To set up an SU in the SU Database, complete the following steps: 1. Connect to the AP (see Getting Started) and open the Subscriber Database page. 2. Enter SU ID 3. Select: either PRIORITY or REGULAR. 4. If SU will be part of an SU to SU group, enter the SU to SU group number. 5. CIR up: (SU to AP Committed Information Rate) – minimum upstream bandwidth for the SU in Kbps. 6. CIR dn: (AP to SU Committed Information Rate) – minimum downstream bandwidth for the SU in Kbps. 7. MIR up: (SU to AP Maximum Information Rate) – maximum upstream bandwidth for the SU in Kbps. 8. MIR dn: (AP to SU Maximum Information Rate) – maximum downstream bandwidth for the SU in Kbps. 9. Device ID is the MAC Address of the SU 10. Save and Activate changes Important! Always remember to Save and Activate changes, or the SUDB will revert back to its previous state after power cycle or reboot. Trango Broadband Wireless — User Manual Access5830 Rev. D Page 10 Basic Configuration via Browser Interface Configure Other Basic AP Parameters In addition to setting up the SU in the SU Database, the following settings from the AP’s Configuration page must be set (or left at default). Base ID: Four character, alphanumeric, user definable base station ID. Input of BASEID shall be in the format of xxxx. Where x is any character from the set : { 0..9; a..z; A..Z; '!@#$%^&*()_+[]\<>,./?' } . The Base ID is typically assigned to a single AP or a group of APs at a particular cell site. The Base ID in AP must match the Base ID in SU in order for link to be established. This parameter can only be changed while opmode is "OFF". AP ID: User definable AP ID (00-FF). This parameter is for informational purposes only and does not play a role in authentication or the establishment of a working wireless link. This parameter can only be changed while opmode is “OFF”. IP Address, Subnet Mask, Gateway: The IP configuration of this radio for configuration, and network management purposes. Since this is a layer-II device, these parameters do not play a role in the establishment of the wireless link. Default Opmode: Operation mode of the radio after power cycle or reboot. When the radio enters "AP" mode, it will be transmitting. When the radio enters "OFF" mode the radio is not transmitting, but can be accessible via the Ethernet port. The radio can be put into opmode "OFF" regardless of its default opmode by telnetting into the radio within the first 30 seconds after power cycle or reboot. Active Channel/Polarization: The current channel and antenna polarization of this unit when Opmode is "AP". To configure the AP’s other basic settings, complete the following steps: 1. Connect to the AP (see Getting Started) and open the Configuration page. Trango Broadband Wireless — User Manual Access5830 Rev. D Page 11 Basic Configuration via Browser Interface 2. Set Base ID (Must match the SU) 3. Set AP ID (used to identify the AP, not essential to establishing a link) 4. Set IP, Subnet, and Gateway (Not essential for a link) 5. Set Default Opmode to "ON" 6. Set Active Channel 7. Set Antenna Polarization (H or V) or choose E for external antenna 8. Save and Activate Settings 9. Reboot System At this point the AP will begin actively searching for any SU in its SU database. Once an active SU is detected, the authentication and association process will begin. The red LED on the bottom of the AP should be lit, indicating that the radio is in Opmode “AP” and transmitting. Trango Broadband Wireless — User Manual Access5830 Rev. D Page 12 Basic Configuration via Browser Interface Configure Basic SU Parameters In order to establish a working link, the Base ID in the SU must match the Base ID of the AP To set up the SU, complete the following steps: 1. Connect to the SU (see Getting Started) and open the Configuration page. 2. Set Base ID (Must match the AP) 3. Set IP, Subnet, and Gateway (Not essential for a link) 4. Set Default Opmode to "ON" 5. Save and Activate Settings 6. Reboot System (This will terminate your HTTP session) At this point, if all parameters have been set correctly, and if the radios are within range – a wireless link between the AP and SU will automatically become established. LED Summary At this point it is useful to learn about the various LEDs which can be found on the bottom of the radio These LEDs can assist the user in determining radio and link status. It should be noted, however, that in “Survey” mode, no LEDs shall light up except the LNKST and ACTST LEDs. The unit shall have LED indicators to indicate the following: a) 10/100 LED Green: Illuminated when link speed is negotiated at 100 BaseT. It is off when link speed is 10 BaseT. Trango Broadband Wireless — User Manual Access5830 Rev. D Page 13 Basic Configuration via Browser Interface b) ACT LED Red: Link and Activity. Illuminated when a link is established. Will blink when link activity is detected. c) RSSI LEDs (4) In all modes except “Survey”, the unit’s four yellow LEDs shall indicates the level of RF signal being received from a valid AP. Yellow LED 1 (leftmost): On when RSSI is greater or equal to –85 dBm Yellow LED 2 : On when RSSI is greater or equal to –75 dBm Yellow LED 3 : On when RSSI is greater or equal to –65 dBm Yellow LED 4 (rightmost): On when RSSI is greater or equal to –55 dBm. If no signal is detected the LEDs will not be on at all. In addition, these 4 LEDs shall flash once to indicate the 'factory reset' button has been activated. d) ASSOCIATION LED(green): Blinking at: Once every second when unit is powered on but opmode is OFF Twice per second while in SU opmode and scanning for an AP. Solid after unit is associated with an AP. Figure 4-1 Bottom of M900S Radio with LEDs Insert new LED picture here Evaluate Link Quality It takes approximately 60 seconds for the radios to complete the boot-up cycle, which includes switching on the Opmode, handshaking, and association. If the AP is busy servicing many SUs, the association process may take slightly longer. The radio’s firmware includes several useful tools to assist in determining which SUs are associated, and the quality of each link. One method for verifying link quality is by using the Link Control page. Insert Link Control Page Here On this page the user can immediately see which SUs have associated. In the page shown, SU ID# 107 is associated, and SU IDs 11, 22, 33, and 44 are not. Consider "Power Off" status synonymous with "not associated." Powerleveling takes place automatically every time an SU associates, so in most cases it is not necessary to manually run powerleveling. Power leveling is described in the deployment section of this manual. RF Link Loopback Test The RF Link Loopback test in one of the built-in tools for evaluating the quality of the wireless link. Specify an SU ID and time in minutes to conduct the test. The test is prioritized, so it will take precedence over all other traffic. 1600 byte packets are sent and received between the SU and AP at 50 millisecond intervals over the time specified. The success rate, and number of packets in bytes is reported for SU and AP Received. Trango Broadband Wireless — User Manual Access5830 Rev. D Page 14 Basic Configuration via Browser Interface SU Ranging / RSSI Test For specified SU reports the distance from AP in miles, SU Tx Power, SU temperature, and the received signal strength for uplink and downlink. Use a link budget calculator to analyze results. Advanced Setup Page The advanced set up page includes several important parameters including RF TX Power, target RSSI from SU (AP only). This screen also includes the radio’s channel table which can be configured by the user. RF Tx Power: Sets the conducted RF power output of the radio. Highest allowable setting is 26 dBm. Lowest setting is –4 dBm. This value does not include antenna gain. Higher number is more power. RF Rx Threshold: Sets the receive threshold of the radio. The radio will not process signals received below this level, so it is very useful for interference mitigation. For smaller radius of operation use a higher threshold (-75 is higher than -80). Target RSSI from SU: Used by the powerleveling process to automatically adjust the RF output power level of all SUs in a sector so the signal strength from each SU as measured at the AP will be roughly equal. Make sure that all SUs are power leveled after changing this number (See Link Control page). Trango Broadband Wireless — User Manual Access5830 Rev. D Page 15 Basic Configuration via Browser Interface Channel Table: Assigns channel numbers to actual frequencies of operation. Default settings allow the largest number of channels (4) within the band, while still maintaining 6 MHz channel spacing. Other Key Parameters This section describes the remainder of the parameters listed on the System Information page. Most of these parameters are the same for both APs and SUs. Hardware Version: Hardware version is factory-set and can not be changed by user. FPGA Version: Low level field programmable gate array firmware currently loaded on the radio. Normally the FPGA firmware will not require upgrading. Firmware Version: Main firmware. In this example, the version part of the string is 0p1 (v0.1) , the hardware code is H8005, and the remainder of the string is a date code. Device ID: MAC address of the radio. S/N: Serial number of the radio. Telnetd Port: User changeable telnet port of radio. TFTPd: Current status of TFTP daemon. Used for uploading firmware. MIR Threshold: Enable/Disable the Maximum Information Rate (MIR) Threshold. The MIR Threshold is the aggregate throughput on the AP at which the AP will start to enforce CIR rules for SUs. Active Channel: The channel currently being used by the radio. Trango Broadband Wireless — User Manual Access5830 Rev. D Page 16 Basic Configuration via Browser Interface RFRx Threshold: Sets the receive threshold of the radio. The radio will not process signals received below this level, so it is very useful for interference mitigation. For smaller radius of operation use a higher threshold (-65 is higher than -70). Broadcast Packet: This software switch (0) enables/disables the blocking of Ethernet control packet except ICMP and ARP to reduce the amount of unnecessary overhead introduced to the wireless link. SU to SU Communication: If enabled (via switch 3), SUs with matching SU to SU groups (except group 0) can communicate in peerto-peer mode via the AP without the need for a router behind the AP. TCP/IP Service for SU: If enabled, the AP can be accessed via TCP/IP (Telnet or HTTP) from the SU side of the network via the wireless link. Remarks: User definable radio information (i.e. customer name, address of installation, and so on). Maximum 28 characters can be stored Site Survey Page This is a useful tool for detecting interference. It is not meant as a substitute for a Spectrum Analyzer. The radio must be in Opmode "Off" in order to use this feature. Enter the number of minutes desired for the survey, and select the polarization (H or V), or E for external antenna. Click "Start Survey". A survey of the default 4 channels will be performed. Results are reported in dBm per channel as average and peak. A channel is reported to be "Clear" if the peak and average are below the RF Rx Threshold by more than 8 dB. Trango Broadband Wireless — User Manual Access5830 Rev. D Page 17 Basic Configuration via CLI Section 5 Basic Configuration via CLI It is important for users to be familiar with the CLI interface as well as the Browser Interface. This section covers how to utilize the radio’s CLI interface to establish a working wireless link. Much of the information presented here is similar to the information presented in Section 4. In this section, the most common settings are discussed using the CLI. Topics include: ?? Access Point Basic Settings ?? Subscriber Unit Basic Settings ?? Subscriber Unit Database Settings A comprehensive treatment of radio settings is found in the appendix on the Command Set Reference. See “Getting Started” section for description of how to access the radio via Telnet or Serial Interface Access Point Basic Settings After logging onto an AP or SU , it is good practice to type the sysinfo command to see the radio’s basic system information. Example (Access Point): insert AP sysinfo example here Many of these parameters can be changed by the user. A description of each of these changeable parameters, along with the related command is shown in the table below. Important! When changing settings, it is usually necessary to type the save ss command in order to update the radio’s flash memory. If you do not type the save ss command, the setting will be lost the next time the radio is rebooted. The command save ss is equivilent to updateflash systemsetting.
