Introduction Section 1 Introduction Your Trango Broadband M915S radio system provides a reliable and robust means to deliver broadband access to a wide geographic region through wireless Ethernet connectivity. This section will familiarize you with basic operational concepts, as well as an overview of the various components and hardware of the M915S system.
Introduction The M915S radios are powered using "power-over-Ethernet" for ease and low-cost installation. A single Cat-5 cable caries both Ethernet and DC power to the radio. Both APs and SUs feature a handy "site survey" tool to check for interference, as well as RSSI tools for optimizing antenna positioning. The M915S also features variable receiver threshold, full power control, dual polarized antennas, and various link diagnostic tools.
Hardware Overview Section 2 Hardware Overview This section provides details about each radio in the M915S family. The M915S-SU and M915S-AP include builtin, electronically switchable, dual-polarized antennas, as well as a reverse polarity SMA connector for the attachment of an external antenna. Both units are designed for outdoor installation, and are powered by powerover-Ethernet (POE) for ease of installation.
Getting Started Trango Broadband Wireless MODEL: M915S-AP Rev.
Getting Started • 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.
Getting Started Several functions, such as the site survey function and the SU RSSI function, can only be performed while the radio is in a particular Opmode. See Appendix A – Command Set Reference for a complete listing of commands, and the appropriate Opmode(s) for each command. Switch Settings M915S firmware includes several “switches” that 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.

Basic Configuration via Browser Interface Section 4 Basic Configuration via Browser Interface This section describes a few more basic concepts, as well as how to establish a wireless link 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.
Basic Configuration via Browser Interface CIR DOWN: Committed Information Rate from AP to SU. Minimum downstream data 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 data 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.
Basic Configuration via Browser Interface 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. Enter Device ID (MAC Address of the SU). 10. Save and Activate changes.
Basic Configuration via Browser Interface 2. Set Base ID, or choose the default Base ID of 0000. (Must match the SU.) 3. Set AP ID (00-FF HEX), or choose the default, which is last two bytes of MAC Address. 4. Set IP, Subnet, and Gateway, or leave at default settings. Keep in mind, if you change the IP Settings of the radio, you will loose your HTTP session when you Save and Activate Settings. 5. Choose Active Channel (1-4). 6.
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 set in the AP. SU Basic Setup: 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, or leave at default settings. Keep in mind, if you change the IP Settings of the radio, you will loose your HTTP session when you Save and Activate Settings. 4.
Basic Configuration via Browser Interface LED Summary At this point it is useful to learn about the LEDs that can be found on the bottom of the radio. These LEDs can assist the user in determining radio and link status. RSSI LEDs (YELLOW) - In all modes except "Survey," the unit's four yellow LEDs indicate the level of RF signal being received from a valid AP. ASSOCIATION LED (GREEN) Blinking once every second in Opmode "OFF" (AP and SU).
Basic Configuration via Browser Interface Link Control Page 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. On this page the user can immediately see which SUs have associated. In the page shown, SU ID# 1 is associated, and SU ID 17 is not. Consider "Power Off" status synonymous with "not associated.
Basic Configuration via Browser Interface SU Ranging Test This test reports the SU’s distance from the AP in miles, received signal strength for uplink and downlink, and SU Tx Power. Use a link budget calculator to analyze results. Advanced Setup Page The Advanced Set up page includes several important parameters including RF TX Power, RF RX Threshold, Target RSSI from SU (AP only), and Channel Table. RF TX Power: Sets the conducted RF power output of the radio. Highest allowable setting is 26 dBm.
Basic Configuration via Browser Interface 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 cannot be changed by the user. FPGA Version: Low-level field programmable gate array firmware currently loaded on the radio. Normally the FPGA firmware will not require upgrading.
Basic Configuration via Browser Interface Site Survey Page The Site Survey page provides a useful tool for detecting and measuring interference. 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, V, or E (for an 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.
Basic Configuration via CLI Section 5 Basic Configuration via CLI This section covers how to utilize the radio’s CLI interface to establish a working wireless link. In this section the most basic settings using the CLI are discussed. Topics include: • Access Point Basic Settings • Subscriber Unit Database Settings • Subscriber Unit Basic Settings See Appendix A − Command Set Reference for a complete listing of the CLI commands.
Basic Configuration via CLI AP SYSTEM INFORMATION PARAMETERS AND RELATED COMMANDS AP Parameter Description Related CLI Command AP ID This parameter provides a set apid (00-FF in HEX) unique number for each AP. If Target AP is specified on SU, Example: #>set apid 33 the SU can only authenticate with the specified AP. The default AP ID is the last two bytes of the MAC address. Opmode Current Opmode of the radio. opmode on y This sets the radio to Opmode “ON.
Basic Configuration via CLI AP SYSTEM INFORMATION PARAMETERS AND RELATED COMMANDS AP Parameter Description Related CLI Command MIR Threshold (Kbps) User specified MIR Threshold. mirth [<0..3, Mbps>] To specify total throughput level that the AP will serve only Example: #>mirth 2 CIR (committed information rate) to associated SUs. When MIR Threshold is disabled, the AP will serve MIR for all its SUs.
Basic Configuration via CLI AP SYSTEM INFORMATION PARAMETERS AND RELATED COMMANDS AP Parameter Description Related CLI Command turned on, multiple SU’s within the same sector (meaning associated to that AP) can communicate with each other, provided they have the same SU2SU group number. TCP/IP for SU This software switch (7) when sw 7 [] (default is on) on, allows users on the SU side Example: #>sw 7 off of the network to telnet or HTTP into the AP.
Basic Configuration via CLI #>sudb cirmir 5 128 256 3000 3000 In this example, SU #5’s CIR downstream was set to 128, and its CIR upstream to 256. MIR upstream and downstream were set to 3000. To change the default CIR/MIR values, use the following command: sudb defaultcirmir Example: #>sudb defaultcirmir 256 256 512 512 To view the entries in the SUDB, type the command sudb view.

Please note that if the radio is attached to a metal pole that is earth-grounded, no other grounding is necessary.
Mounting Hardware Installation Notes Access to the radio’s RJ-45 Port and LED status lights are purposely located at the bottom of the radio to minimize the risk of water intrusion. Do not mount the radio upside down. The J-Box is not a weatherized device, and must be located either indoors or in a weather-protected cabinet. Shielded twisted pair Cat-5 cable is recommended for all installations unless the cable is placed in metal conduit.
Deployment Section 7 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 • Channel Planning • SU Antenna Alignment • Link Management Commands Site Selection Proper site selection for your AP will help ensure a successful deployment.
Deployment Example:\ #> survey 2 v Press [space] then [enter] to stop 880 882 884 886 888 890 892 894 896 898 900 902 904 906 908 910 912 914 916 918 920 922 924 926 928 930 932 934 936 938 940 942 944 946 948 950 MHz MHz MHz MHz MHz MHz MHz MHz MHz MHz MHz MHz MHz MHz MHz MHz MHz MHz MHz MHz MHz MHz MHz MHz MHz MHz MHz MHz MHz MHz MHz MHz MHz MHz MHz MHz Ch 1 Ch 2 Ch 3 Ch 4 peak peak peak peak peak peak peak peak peak peak peak peak peak peak peak peak peak peak peak peak peak peak peak peak peak peak
Deployment In conjunction with the RSSI command, it is also useful to perform the apsearch command that will tell you which AP is providing an adequate signal at the location of the SU. AP Search 1. 2. Ensure AP is in Opmode “On.” Run the apsearch command to verify which AP is providing the strongest signal strength. In this example, an AP is detected on channel 1, polarization horizontal. Further, the Base ID is 1234, and the MAC address is 00 01 DE 15 5C D0.
Deployment 3 LED 4 LED -65 dBm -60 dBm Collocation and Channel Planning With proper channel planning and adherence to installation guidelines, multiple M915S APs may co-exist and operate interference-free on the same tower or building. The main consideration when collocating APs is to ensure at least 10 ft. of vertical separation. See the diagram below for collocation spacing, and a suggested channel plan.
Deployment In establishing and diagnosing the quality of the link between the AP and SU(s), there are a few commands that are especially useful. All of these commands are performed at the AP. A summary of these commands follows: su Displays the status of all SUs in the AP’s SUDB. SUs in the SUDB will appear by SU ID, and are classified into one of the following status categories: Associated, Associating, and OFF. Example: #> su [Priority] 88 [0] [1] [2] [3] 88 [4] [5] [Associating] [Power Off] Success.
Deployment Success. [ip] 192.168.100.120 [subnet] 255.255.255.0 [gateway] 192.168.100.
Management The “r” is used in this command to repeat the RF link test repeatedly until the user terminates the test by hitting SPACE ENTER. Example: #> su testrflink 88 r Press [space] then [enter] to stop [len] 1512 [suid] 88 [ 0] ...........[AP Tx] 20 [AP Rx] [ 1] ...........[AP Tx] 20 [AP Rx] [ 2] ...........[AP Tx] 20 [AP Rx] [ 3] ...........[AP Tx] 20 [AP Rx] [ 4] ...........[AP Tx] 20 [AP Rx] [ 5] ...........
Management Section 8 Management Section Topics: • Radio Management Access using TCP/IP • SU Management from the AP’s command set • SNMP Radio Management Access Via TCP/IP The IP Address of an M915S radio is for management purposes only. The IP address is not used for purposes of routing or passing traffic. Users should take care to set appropriate IP schemes for all management activities including upgrading the radio’s firmware.
Management Loading Multiple SUs into the SUDB using DLOAD Command To load a full database of SU entries into the AP’s SUDB, you need to create a subscriber database in ASCII text file format. As shown below, each row represents all information for one SU. Each column is an information field, which includes: SU ID, SU to SU group, service level, CIR, MIR, and MAC address.
Management The Trango SNMP solution supports MIB-II (system only) and the Trango proprietary Management Information Base (MIB). The SNMP agent resides on the AP ONLY. The AP gathers health, status, and performance statistics from all SUs locally, then responds back to the SNMP manager upon request. Users interested in using the SNMP functionality should review the entire M915S MIB for a complete understanding of its features. The M915S MIB is available for download at: http://www.trangobroadband.
Management 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. 2. Unzip trangopkg.zip file to a local temporary directory. Go to your local temporary directory, you will see 4 files shown below. a. b. c. d. 3. 4. 5. 6. trango_M915Sap_1p0.mib – M915S AP MIB file trango.
