Overview Chapter 1 Overview The ATLAS4900 is a point-to-point (PtP) wireless Ethernet transmission system which provides network connectivity at speeds up to 45 Mbps depending on the transmission distance and noise floor. The Atlas4900 utilizes OFDM technology and is designed for use in long range backhaul and wide area data networking applications.
Overview Range vs. Throughput The following table shows approximate maximum ranges (at recommended fade margins) achievable with the ATLAS4900 system using various antenna configurations. Longer ranges are achievable, but will result in lower fade margins.
Overview System Contents Each ATLAS4900-INT kit consists of two P4900M-INT radios, two power-over-Ethernet (PoE) injectors, two AC adapters, port covers, and mounting hardware. A dual-polarized integrated antenna is located behind the radome of the P4900M-INT.
Overview Location of RJ-45/LED Port The RJ-45 connector, diagnostic LEDs, and reset button are located at the bottom of the radio. Functionality of the LEDs is described later in this text. The reset button resets IP address and password back to factory default. Hold the reset button down for 5 seconds (until amber lights flash) while unit is powered on.
Getting Started Chapter 2 Getting Started It is recommended that you first provision and test your the radios on the bench before deploying them in the field. This is a particularly useful exercise for the novice user. Connections and Power • 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).
Getting Started This text covers configuration through the CLI. For HTTP configuration please see Appendix A. Telnet Open a command prompt (DOS) session on your PC. Open a Telnet session by typing: telnet Example: C:>telnet 192.168.100.100 Note: All Trango radios are pre-configured at the factory with a default IP address of 192.168.100.100. You will be greeted with current hardware and firmware information and prompted for a password. Type in the password and press enter.

Getting Started Example: #> sysinfo 2 ********************************* 2 ********************************* [Opmode] off [Default Opmode] off [Active Channel] 1 h [Freq] 4950 MHz [Speed] 24 Mbps [Tx Power] 0 dBm [Power Range] -4..19 dBm [Peer ID] DE1B7850 [Status] disconnected [RSSI] -49 dBm Success.
Configuration Chapter 3 Configuration Key Concepts Prior to configuring the radios it is important to understand several key concepts: Master Unit (MU) The MU is typically considered the primary radio within the link. For management purposes it is recommended to install the MU closest to the head-end of the network. Remote Unit (RU) The RU is typically installed at the remote end of the link.
Configuration Ch# 1 h (4950 MHz) Success. 4. Set default Opmode to ON. #> defaultopmode on Success. 5. Turn Opmode ON. #> opmode on Success. . Remote Unit Configuration Configure the RU in the same manner as the MU. Since the default unit type (utype) is RU, you do not need to set this parameter. 1. Set the Peer ID with the MAC address of the MU. Only use the last 8 digits of the MAC address. #> peerid de1B7842 Success. #> 2. Set channel and polarization.
Configuration The [status] field indicates whether the MU and RU are connected or disconnected. If connected, the MU and RU will automatically start passing Ethernet traffic over the wireless link. Changing IP Address Use the ipconfig command to change the radio’s ip address, subnet mask and gateway. Syntax: ipconfig [ ] Example: #> ipconfig 10.8.2.140 255.255.255.240 10.8.2.129 New configuration: [ip] 10.8.2.140 [subnet mask] 255.255.255.240 [gateway] 10.8.2.
Configuration - Twice per second while in opmode ON and scanning for an MU or RU. - Solid after unit is associated with the RU or MU. RF Link Loopback Test (linktest command) The linktest command tests the throughput and packet error rate (PER) on the current channel for each direction at all speeds and reports results. This command also provides RSSI for both ends of the wireless link. The command can be run from either the MU or the RU.
Configuration 48 54 -75 -73 17 17 7 7 In this example the user sets the power to 19dBm and the speed to 24 Mbps: #> power 19 Execution in progress... . 19 dBm (-4..19) Success. #> speed 24 24 Mbps Success. #> Command Reference Listing The complete command set reference is provided below.

Deployment & Installation Chapter 4 Deployment & Installation Once you are familiar with the basic operation of the radios you are ready for deployment in the field. The deployment process consists of the following steps: • Site Selection • Site survey at MU and RU sites • MU installation • RU installation and antenna alignment • Link test Site Selection Proper site selection for your MU will help ensure a successful deployment.
Deployment & Installation RSSI Command and Antenna Alignment Once the site survey is completed, you are ready to install your radios. Typically it is best to install the MU first. To properly align the radios, use the built-in RSSI tool to achieve maximum signal strength. 1. Ensure MU and RU are in Opmode “ON.” 2. Connect to the RU. 3. Login and type the command rssi. As you read the RSSI, move the antenna in the horizontal and vertical planes until the maximum RSSI reading is achieved 4.
Deployment & Installation Port Plug and Port Plate Prior to deployment, insert the silicone port plug around the Cat-5 Cable and insert into the radio’s port opening. Next, screw the port plate over the silicone plug as shown in the photographs below. Mounting Hardware Radios are supplied with mounting hardware for pole installations. See diagram below for proper use of the mounting hardware. 8.50 MAX 10.00° UPTILT 25.
SNMP Grounding Proper mounting of the radio includes consideration for grounding. Please note that if the radio is attached to a metal pole that 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 radio as in the adjacent diagram. Cabling and Weather Considerations Shielded twisted pair Cat-5 cable is recommended for all installations.
SNMP Chapter 5 SNMP The Atlas supports SNMP (Simple Network Management Protocol). Network management consists of the following 3 categories: configuration, Link and Association monitoring and Alarms. Besides this proprietary Management Information Base (MIB) the Atlas also supports a large part of the MIB-II OIDs. Review the Trango MIB (TRANGO-P5M-MIB.mib) available on our website for the complete listing of all MIB objects available.

Appendix A Command Set Reference Site Survey Page The site survey function measures overall noise floor as well as in-band noise containing data packets. Noise is reported in terms of average and peak dBm for the period tested. The user specifies duration of the test in minutes as well as the antenna port. In this example the site survey function was performed for 1 minute on the vertical polarity.
Appendix A Command Set Reference Link Control The Link Control page features the RF Link Loopback / Speed Test. In this test, the user specifies the transmission rate (in Mbps) in both the local radio and the peer radio as well as the duration time (in minutes) for the test. During the test, the local radio will transmit packets across the wireless link. The peer radio will retransmit equivalent packets back to the local radio.
