Introduction    Trango Broadband Wireless — User Manual Access5830  Rev. D Page 1  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.
Introduction    Trango Broadband Wireless — User Manual Access5830  Rev. D Page 2  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”.
Hardware Overview    Trango Broadband Wireless — User Manual Access5830  Rev. D Page 3  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.

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 M9000S-AP                Rev.

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”.
Getting Started    Trango Broadband Wireless — User Manual Access5830  Rev. D Page 6  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.
Getting Started    Trango Broadband Wireless — User Manual Access5830  Rev. D Page 7  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.
Getting Started    Trango Broadband Wireless — User Manual Access5830  Rev. D Page 8   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 help <command> for 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.
Basic Configuration via Browser Interface    Trango Broadband Wireless — User Manual Access5830  Rev. D Page 9   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.
Basic Configuration via Browser Interface    Trango Broadband Wireless — User Manual Access5830  Rev. D Page 10     . 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.
Basic Configuration via Browser Interface    Trango Broadband Wireless — User Manual Access5830  Rev. D Page 11  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.
Basic Configuration via Browser Interface    Trango Broadband Wireless — User Manual Access5830  Rev. D Page 12   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.
Basic Configuration via Browser Interface    Trango Broadband Wireless — User Manual Access5830  Rev. D Page 13  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.
Basic Configuration via Browser Interface    Trango Broadband Wireless — User Manual Access5830  Rev. D Page 14  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.

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.

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).

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.
Basic Configuration via Browser Interface    Trango Broadband Wireless — User Manual Access5830  Rev. D Page 17  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 peer-to-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.

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.

Informational Parameter   Subscriber Unit Database Settings Once you are familiar with the AP’s basic system information presented above, you are ready to add one or more SUs to the SU database (sudb).  There are three basic commands related to the SU database:  sudb add, sudb cirmir, sudb defaultcirmir, sudb view, and save sudb.  Adding an SU To add an SU to the database, you will need to know the following information:
Basic Configuration via CLI    Trango Broadband Wireless — User Manual Access5830  Rev. D Page 22  1. MAC ID of SU (printed on the back of the SU) 2. Polling priority; either PRIORITY or REGULAR.      ?  Note:   SUs designated as PRIORITY will get polled more often by the AP.  To add an SU to the database, use the following command and syntax:  sudb add <suid> <pr|reg> <device id> suid: SU ID pr: priority user reg: regular user <device id>: xx xx xx xx xx xx in hexadecimal (this is the MAC address of the SU)  Example:  #>sudb add 5 pr F3 3C 50 67 89 D4  In this example an SU ID 5 was added as a Priority SU .  The MAC ID of this SU is F3 3C 50 67 89 D4.  ?  Note:  You can add up to 2000 entries in the SU database.  It is recommended that users not enter any more SU’s than necessary since excessive numbers of inactive SU’s in the database may negatively impact system performance.  CIR / MIR Commands  The default CIR/MIR setting is 3000 kbps  for upsteam and downstream values.  To change the SU’s CIR/MIR settings, use the following command: sudb cirmir <<suid>|all> <cir dn> <cir up> <mir dn> <mir up>  Example: #>sudb cirmir 5 128 256 3000 3000  To change the default CIR/MIR values, use the following command: sudb defaultcirmir <default cir dn> <default cir up> <default mir dn> <default mir up> Example:  #>sudb defaultcirmir 256 256 512 512   To view the entries in the SU database, type the command sudb view.  To save the changes you have made to the SU database, type save sudb  Other important SU database related commands are sudb delete and sudb modify.  See Appendix D for detailed descriptions of these commands.   ! Important!  After updating the SU database, type the command save  sudb to save the SU database.  If you do not save, the sudb file will revert back to its previous state after power cycle or reboot.

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.
Mounting Hardware    Trango Broadband Wireless — User Manual Access5830  Rev. D Page 25   ?  Note:  Access to the radio 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.  ?  Note:  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.  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.  ?  Note:  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.  ?  Note:  It is important to provide strain relief and drip loop for STP Cat-5 cables.
Deployment    Trango Broadband Wireless — User Manual Access5830  Rev. D Page 26   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.   Site selection will depend on a wide variety of factors, but from the radio’s performance standpoint, please consider the following: ?? Path from AP to SU should provide as few obstructions as possible, thus it is advisable to place AP as high as possible on a tall building or tower ?? Ethernet cable limit is 300 feet from Ethernet device (router, switch) to radio ?? Radios require grounding for optimal performance ?? AP provides sector coverage of 60 degrees azimuth and 10 degrees elevation ?? Consider nearby sources of interference which could degrade performance of radio.  Mount radios as far from sources of interference as possible ?  Note:  See Appendix C – RF Primer for more information on site selection. Site Survey Both the AP and SU provide a powerful on-board site survey tool.  This tool will tell you if there is interference present in the 900 MHz ISM  band.  In order to use the survey command, 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 AP.    The survey can be run from either the browser interface or the command line interface.  See Example on following page:  #> survey 30 h Running site survey for 30 secs.  Press any key to stop

It is recommended that APs be installed first.  The reason for this is that the SU has a built-in RSSI tool which will help you properly aim the SU at the AP to achieve maximum signal strength. AP Search and SU Antenna Alignment Once the AP is installed, and aligned in the correct general direction, it is time to install the SU.  The hardware installation of the SU is identical to the AP, including considerations for line-of-sight, cable distances, cable type, weather sealing, and grounding.  Once the SU is installed and aimed in the general direction of the AP, it is time to perform an RSSI (relative signal strength indicator) test to determine the signal strength from the AP, and to precisely align the SU antenna for maximum signal strength.  Although it is possible to rely upon the subscriber unit’s LEDs for alignment, more precise RSSI readings are available from the  command line interface SSRSSI command.    In conjunction with the SSRSSI command, it is also useful to perform the APSEARCH command which will tell you which AP is providing an adequate signal at the location of the SU.  AP Search  1. Ensure AP is in opmode “AP” 2. Run the APSearch command to verify which AP is providing the strongest signal strength. Example: #> apsearch Ch 1 906 MHz h peak -99 dBm avg -96 dBm              v peak -99 dBm avg -97 dBm              e peak -99 dBm avg -97 dBm Ch 2 912 MHz h peak -99 dBm avg -97 dBm              v peak -99 dBm avg -97 dBm              e peak -99 dBm avg -97 dBm Ch 3 918 MHz h peak -99 dBm avg -97 dBm              v peak -99 dBm avg -97 dBm              e peak -99 dBm avg -97 dBm Ch 4 924 MHz h peak -44 dBm avg -45 dBm  B11 A 1  peak -44 dBm avg -45 dBm rx 1545 pkts               v peak –62 dBm avg -75 dBm              e peak -99 dBm avg -97 dBm #>  SSRSSI Command for Antenna Alignment Step 1    Telnet into the SU (while in Opmode “OFF”).  Type command ssrssi <channel> <polarization>    In this example of a survey on horizontal polarization for 30 seconds, the largest amount of energy is detected on channel 4.    The asterisks, ****, indicate the highest amounts of energy detected and correspond to the number of amber colored LEDs lit. In this example, an AP is detected on channel 4, polarization horizontal.  Further, the Base ID is 11, and the AP ID is 1.
Deployment    Trango Broadband Wireless — User Manual Access5830  Rev. D Page 28  Step 2    The telnet session screen will begin a continuous readout of the received signal strength.  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 –80 dBm is acceptable.  Any RSSI of less than –85 dBm may be too weak for the radios to reliably associate and pass data.   Examples: #> ssrssi 2 v Press [space] then [enter] to stop AP  ?  -97 dBm AP  ?  -97 dBm AP  ?  -97 dBm #>  #> ssrssi 6 v Press [space] then [enter] to stop AP  ?  -58 dBm AP  ?  -58 dBm AP  ?  -58 dBm #>  #> ssrssi 6 h Press [space] then [enter] to stop AP 11  -44 dBm AP 11  -46 dBm AP 11  -47 dBm #>  Step 3    If it is not possible to receive an adequate RSSI reading, it may be necessary to reorient the AP (up/down, left/right), to increase the output power of the AP, or to move the SU to a location with better line-of-sight conditions to the AP.  Once you are satisfied with the RSSI reading, tighten down the SU in the optimum position.  To stop the RSSI continuous readout, hit SPACE ENTER.  SU Alignment Using LEDs  The LED RSSI indicators on the bottom of the radio provide a handy alignment tool.   If all four LEDs are lit, the unit is receiving –60 dBm or stronger.  If no LEDs are lit, there is not sufficient signal strength to establish a wireless link.  Lit LEDs   Signal Strength 0 LED  <-85 dBm 1 LED  -85 dBm 2 LED  -80 dBm 3 LED  -75 dBm 4 LED  -70 dBm   Link Management Commands Once the radios are properly aligned for maximum RSSI,  ensure the SU’s default Opmode is “ON” and that all configuration parameters are correct.    Reboot the SU.  Once the SU enters Opmode “ON”, the authentication process will begin, and the two radios will begin to associate.  From the AP side, there are several basic diagnostics commands such as su ping, su status, and su testrflink to ensure that a reliable RF link has been established.  It may take one minute or more for the association process to complete.  This process may take longer if there are many SUs in the sector.  If all tests show favorable results, the wireless link will automatically begin passing Ethernet traffic between the radios. ssrssi 2 v — In this example very little energy was detected, although the AP was in Opmode "AP", since the wrong frequency and polarization were used.   ssrssi 6 v — In this example the right channel was used, but the wrong polarization, so a significant amount of energy was detected, the AP can not be discerned because the SU is looking for energy on a particular frequency and polarization.  ssrssi 6 h — Here, the correct channel and polarization show the most energy, and the SU is able to discern the AP ID.
Deployment    Trango Broadband Wireless — User Manual Access5830  Rev. D Page 29   In establishing and diagnosing the quality of the link between AP and SU(s), there are a few commands which 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 database.  SUs in the SU database will appear by SU ID, classified into one of the following status categories:   Associated, Associating, and OFF.    su live Displays a list of SU’s that are currently associating with the AP (by SU ID).   Example: #> su live -----------    Live   ----------- 88 --> 1 SU  Success.  ?  Note:  In this, and the following, examples the SU ID is 88  su ping <su#> AP will send 10 RF pings to the designated SU ID.  The response from each ping will indicate latency (in micro-seconds) and the strength (RSSI) of the signal received back from the SU for each of the 10 pings.  Note this command will also tell you the distance from the AP to the SU. Example: #> su ping 88 [#Begin] [0088] Ping #0 -> 292 us [-43 dB] Ping #1 -> 288 us [-43 dB] Ping #2 -> 286 us [-43 dB] Ping #3 -> 287 us [-43 dB] Ping #4 -> 287 us [-43 dB] Ping #5 -> 287 us [-43 dB] Ping #6 -> 287 us [-43 dB] Ping #7 -> 287 us [-43 dB] Ping #8 -> 290 us [-43 dB] Ping #9 -> 288 us [-43 dB] suid 88: range[avg/min/max 288/286/292 us] max rssi[-43 dBm] distance[0.1 mi] [#End] Success.  su status <su #>  AP will poll the SU for SU’s current status and will provide information such as SU range from AP, signal strength received at SU from AP, SU temperature, etc. .

AP will send 500 large packets to the SU and the SU will return what it receives to the AP.  Small numbers of errors are inconsequential.  A perfect link (without dropped packets) will yield average throughput over 3,000 kbps.  If heavy packet loss occurs it may be caused by interference or multi-path.  Example: #> linktest 88  [suid] 88 [pkt len] 1600 bytes [# of pkts per cycle] 500 [cycle] 10  0  [AP Tx]500 [AP Rx]500 [AP RxErr]0  [SU Tx]500 [SU Rx]500 [SU RxErr]0    1277ms  3023 kbps 1  [AP Tx]500 [AP Rx]500 [AP RxErr]0  [SU Tx]500 [SU Rx]500 [SU RxErr]0    1278 ms  3019 kbps . . 9  [AP Tx]500 [AP Rx]500 [AP RxErr]0  [SU Tx]500 [SU Rx]500 [SU RxErr]0    1277 ms  3015 kbps  [AP Total nTx]    5000 pkts [AP Total nRx]    5000 pkts [AP Total nRxErr] 0 pkts  [SU Total nTx]    5000 pkts [SU Total nRx]    5000 pkts [SU Total nRxErr] 0 pkts  [AP to SU Error Rate] 0.00 % [SU to AP Error Rate] 0.00 %  [Avg of Throughput]   3002 kbps  su testrflink <su#> This command also checks the integrity of the wireless link from the standpoint of packet loss.  Relative to the Linktest command, however this test does not provide as much detail.  In this test, the AP will send 20 large packets to the SU and the SU will in turn send the same 20 packets back to the AP.  The expected result of an error free link is 20..20..20, indicating (in the following sequence) 20 packets sent from AP, 20 packets received back at AP, 20 packets received at SU.  Any results other than 20..20..20 indicate lost packets, most likely due to interference or inadequate signal to noise ratio.   The “r” is used in this command to repeat the rf link test repeatedly until the user terminates the test by hitting SPACE ENTER. #> su testrflink 8000 r  Press [space] then [enter] to stop [len] 1512 [suid] 8000 [   0] ...........[AP Tx] 20 [AP Rx] 20 [SU Rx] 20 [   1] ...........[AP Tx] 20 [AP Rx] 20 [SU Rx] 20 [   2] ...........[AP Tx] 20 [AP Rx] 20 [SU Rx] 20

For thorough results it is recommended you run the command repeatedly for at least 1 minute or more to determine if packets are passing without error consistently over time.
Management    Trango Broadband Wireless — User Manual Access5830  Rev. D Page 32  Section 8    Management In this section the following topics will be discussed: ?? SU Management from AP ?? TCP/IP SU Management ?? Security ?? SNMP SU Management from AP Network management can be performed by the following methods ?? HTTP Interface       ?? CLI         See Appendix on Command Set Reference ?? SNMP Manager    Discussed in this section, below  The AP provides functionality and several commands which permit the management of associated SUs.  In fact, most  system management functions are performed  by issuing commands from the AP.   Presented below are a few examples of these commands: su <ping|info|status> <suid> su powerleveling <all|suid> su ipconfig <suid> <new IP> <new subnet> <new gateway> su reboot <all|suid> su restart <all|suid> su testrflink <all|suid> [r] su testrflink aptx [<pkt,20..100>] su sw <suid> <sw #> <on|off>  Note:  SU commands issued from the AP will automatically update the SU’s flash memory.  No save ss command is necessary.   As an example, you can change SUs password for a single SU or all SUs in sector:   su password <suid> <pwd> <pwd>   Example: su password 7 hello hello      to remotely change the password on SU#7 to “hello”  As another example, to change the SUs IP, subnet, and gateway:  su ipconfig <suid> <new ip> <new subnet> <new gateway> Type the following: #>su ipconfig 7 192.168.10.10 255.255.255.0 192.168.10.1   In this example SU ID #7’s IP address is changed to 192.168.10.10, the subnet mask is changed to 255.255.255.0, and the gateway is changed to 192.168.10.1.  A complete description of these commands and many others can be found in Appendix on Command Set Summary. TCP/IP of Radio at Other End of Wireless Link As noted in the “Getting Started” section, it is possible to use Telnet and the HTTP interface to manage the SU from the AP side of the wireless connection as long as switch #2 (TCP/IP for AP switch) is turned on at the SU.  To turn on switch 2 (while logged onto the AP) use the following command:  su sw <su-id|all> 2 on  Example:  su sw 2 all on      to turn on switch 2 for all associated SUs.  It is also possible to use Telnet and the HTTP interface to manage the AP from the SU side of the wireless connection as long as switch #7 (TCP/IP for SU switch) is turned on at the AP.  To turn on switch AP (while logged onto the AP) use the following command:  sw 7 on

D Page 33  Loading Multiple SUs into SUDB using DLOAD Command To load a full database of SU entries into the AP database, 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.  0001 0001 3000 9999 0001 de01 0203 --- Subscriber 1 … 0003 0011 5000 9999 0001 de04 0506  0004 0011 0512 9999 0001 de01 0203 --- Subscriber 4 0000 0000 0000 0000 0000 0000 0000 --- End of file indicator ---- ---- ---- ---- --------------   |    ||   |    |         |   |    ||   |    |         |---------- MAC Address   |    ||   |    |-------------------- MIR (Kbps)   |    ||   |------------------------- CIR (Kbps)   |    ||----------------------------- Service level   |    |                              (5: priority user)   |    |                              (1: regular user)   |    |------------------------------ Peer-to-peer group #   |    |                              (1 to F in hex)   |----------------------------------- SU ID (1~8192)                   1. telnet into the AP, run command tftpd on to enable tftp process 2. tftp the file to the AP from your DOS prompt example: tftp <IP of AP> put mySUs.txt 3. telnet into the AP 4. Run command sudb dload to load and activate the database 5. Run command  sudb view to verify the database entries Run command updateflash sudb to write the database to non-volatile memory. SNMP The M900S 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 AP ONLY.  It gathers health and status, 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 Access5830 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 Access5830 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 AP’s RF port. ?? suRfOutOctets – Number of octets of payload received from AP’s RF port.
Management    Trango Broadband Wireless — User Manual Access5830  Rev. D Page 34   AP Bandwidth Monitoring ?? aptrafficEthRxAvgThroughputLog – Average payload data throughput (in Kbits/sec) received on the Ethernet port over the period of 1 minute. ?? aptrafficEthTxAvgThroughputLog –  Average payload data throughput (in Kbits/sec) transmitted on the Ethernet port over a period of 1 minute. ?? aptrafficRfRxAvgThroughputLog – Average payload data throughput (in Kbits/sec) received on the RF link over a period of 1 minute. ?? aptrafficRfTxAvgThroughputLog – Average payload data throughput (in Kbits/sec) transmitted on the RF link over the period of 1 minute. ?? aptrafficEthInOctets – Number of octets of payload received on the Ethernet port ?? aptrafficEthOutOctets – Number of octets of payload transmitted on the Ethernet port ?? aptrafficRfInOctets – Number of octets of payload received on the RF port ?? aptrafficRfOutOctets – Number of octets of payload transmitted on the RF port  Link Status Monitoring –Various traps are defined as follows: ?? Cold start – when SNMP agent starts running ?? Link Up – when the AP enters Opmode “AP” ?? Link Down – when the AP reboots ?? SU Link Up – when SU associates to the AP ?? SU Link Down – when SU disassociates from the AP ?? “AP” Opmode Failure – when AP fails to enter Opmode “AP”  AP and SU 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 subscriber ?? Change channel ?? Set power ?? Set radio sensitivity Review the Trango MIB (trango_m5830sap_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_m900sap_1p0.mib – M900S AP MIB file b. trango.ico – M900S AP icon c. autoico.txt – instruction file (Selects Trango icon automatically during initial set-up.) 3. Copy trango_m900sap_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 AP.  The Trap Community is “SNMP_trap”.  The manager needs to have the same settings in order to communicate with the AP successfully.   To send traps from the AP, 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)  For all the set operations, set object SaveAndActivate at apsystem-apsystemInfo to write the information to FLASH.
