Welcome!
Your Trango Broadband Access5830 radio system provides the latest innovations in high speed fixed wireless broadband. The Access 5830 is a point-to-multipoint (PMP) system which provides network connectivity at speeds up to 10 Mbps with a range of 10 miles or beyond depending on antenna configuration. The Access5830 is unique in that it can operate in either the 5.8 GHz ISM band or the 5.3 GHz U-NII band.
The Access5830 system consists of two types of radios: Access Points (AP) and Subscriber Units (SU). The AP will deliver wireless broadband service to one or more SU’s according to a proprietary polling algorithm called SMARTPolling™. Each AP can associate with and deliver service to up to 512 SU’s. With careful channel planning, (and adequate spacing and shielding) network operators can co-locate up to 22 AP’s at a single cell site.
The AP and SU conform to maximum radiated power limits as established by the FCC.
Band AP Max EIRP Approximate max range (AP to SU)
5.8 GHz ISM Band 36 dBm 6 Miles (allowing for 10 dB fade margin)
5.3 GHz U-NII Band 30 dBm 2 Miles (allowing for 10 dB fade margin)
In this document and within the radio configuration itself, the designators of “ISM” and “U-NII” are used to distinguish between the two bands.
Getting to Know Your Radio
Contents
Each Access 5830 radio comes equipped with the radio itself, a power-over-Ethernet (POE) J-Box, an AC adapter, and mounting hardware. The Access5830 AP (part # M5830S-AP-60) also comes with a serial programming cable. Dual-polarized internal antennas are included within the radome of the AP and the short range SU (Part #M5830S-SU).

APs and SUs look identical. The only way to tell them apart is by the model number printed on the backside product label. This label also contains the MAC ID of the radio as well as the serial #.
Ethernet and Serial Ports
At the bottom of the Access5830 are two access ports: a twist-on weatherproof cable port for RJ-45 Ethernet (and POE), and an access cover (with two screws) for RJ-11 serial port. Most configuration and management tasks can be performed through the Ethernet jack. The access cover also contains a small window which reveals three LEDs. These LEDs provide RF link-status information and will be discussed later in this text.
Antennas
The Access5830 AP and SU each include dual polarized patch antennas built in behind the plastic radome cover. These antennas can be electronically switched between horizontal (H) or vertical (V) polarization.
AP/SU Operational Overview
The Access5830 AP is a sophisticated broadband wireless device that provides a host of comprehensive tools and functions. The AP resides at the center of the point-to-multipoint (PMP) network and performs all management functions including the allocation of bandwidth allocation for all associated SU’s. As such, we refer to The Access5830 is an “AP-Centric” system.
One of the major advantages of the Access5830 system is the ability of the AP to handle multiple SU connections and share the 10 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 unit acts as a hub in a star configuration wireless multipoint network supporting up to 512 subscriber units. The AP unit, hardwired to a network point of presence, polls each subscriber unit 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.

When power is first applied to a properly installed SU, it will scan all the channels in its scantable, searching for an AP that is sending transmit grants for this particular SU. 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. This process involves sending a special command to the SU and getting an instantaneous reply from the SU.
Upon successfully locating and ranging the SU, The AP will then add the SU to the normal polling list and level the RF transmit power level from the SU to set a good signal-to-noise ratio at the AP.
The AP uses several parameters to determine how often each SU is polled for data, and the conditions of any data transfer, as follows:
1) Committed Information Rate (CIR)
2) Maximum Information Rate (MIR)
3) Priority
4) Poll response timeout
All the above parameters are set in the AP by the system administrator and cannot be controlled at the SU. It should also be noted that the MAC table located in the AP is dynamic and stores up to 2000 entries. There is no limitation on the number of IP addresses or hardware devices that an individual SU may have physically connected to it.

Getting Started
First unpack your AP and at least one SU. It is recommended that novice users first provision and test the radios on the bench before deploying in the field.
Connections and Power
Note: Connection and powering of radios is the same for AP’s and SU’s.
• 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). See appendix for PoE pinout diagram for this J-Box to radio connection.
• If connecting to a COMPUTER, use a Cross-Over to the computer’s Ethernet port.
If connecting to a HUB, SWITCH, or ROUTER, use a Straight-Thru
• Plug the AC adapter into an AC outlet.

Note: If you cannot access the radio management functions via the Ethernet port, use the Serial Programming cable (supplied with AP) and attach to RJ-11 located behind access cover on bottom of radio.
Basic Configuration
The Access5830 can be configured using either the Command Line Interface (CLI) or the Web Browser (HTTP) interface. Although both methods are comprehensive and powerful, the CLI method provides slightly more functionality. Regardless of which method is chosen, it is important to gain a good understanding of the major CLI commands available. The entire CLI Command Set Reference is available in a separate document. This user manual focuses on the CLI for radio configuration and management.
The CLI is accessible via telnet session (through Ethernet port) or via the serial port using Hyper-terminal.
If you would like to use the Hyperterminal via PC serial port, use settings 8-N-1 Flow control: None.
Opmode Concept
Before logging on to a radio, it is important to understand the “opmode” concept of the Access5830. AP’s can be in one of two opmodes; “OFF” opmode, or “AP” opmode. When in “OFF” opmode the radio is not radiating RF energy, and it is not attempting to associate with SU’s. “AP” opmode is the normal operating mode of the AP which is used when radiating RF energy and associating with SU’s.
Similarly, SU’s have two opmodes: “SU” opmode or “OFF” opmode.
Opmode is important to understand for the following reason:
You can log onto an AP via Ethernet port (telnet or http browser) regardless of Opmode. However, you can only log onto an SU (via the Ethernet port) when it is in Opmode “OFF”. Factory default opmode is “SU”, however, while booting, the SU will wait 30 seconds before entering opmode “SU”. During this 30 second window, you can log onto the SU while it is in opmode “OFF”. Once you log onto the SU, the progression to opmode “SU” will stop, and the unit will remain in opmode “OFF”. If accessing the SU via the serial programming cable, you can log onto the unit weather it is in opmode “OFF” or opmode “SU”.
Also, certain commands, such as the site survey command (ssurvey) and the SU RSSI command (ssrssi) can only be performed while the radio is in opmode “OFF”. See Appendix 1 Command Set Reference l for a complete listing of commands, and the appropriate opmode(s) for each command.

HTTP Browser Interface
The HTTP browser interface is an easy-to-use configuration and management tool. 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 screen.
Type the password (default trango) and continue. This will bring up a screen similar to the following:
For more information on the HTTP browser interface, please see Appendix 3, or refer to the online HELP button on the browser screen.
Logging On to your Radio via Telnet.
Open a command prompt (DOS) session on your PC. Open a Telnet session by typing
telnet [ip address of radio]
You will be greeted with current hardware and firmware information and prompted for a password. Type in the password and press enter.
All Trango radios (AP and SU) come factory pre-configured with a default IP address
192.168.100.100. The default password is trango.
Prior to deployment you will want to change the password and assign a unique IP address to each radio.

Access Point Set Up and Configuration
It is recommended to set up the AP prior to setting up the SU’s. In the process of configuring the AP, you will:
1. Review and modify basic system information such as Base ID, RF Channel, etc.
2. Add SU’s to the Subscriber Unit Database (SUDB).
Logon to the AP and to receive a comprehensive snapshot of the system’s status, type the command sysinfo. The result appear similar to:
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. Please note that in order to save any changes to persistent storage, you must type the command: updateflash systemsetting. If you do not update the flash, settings will be reset after reboot.
