Trango Radio Features
The Trango FOX 5800 SU offers the same throughput and all popular management features of the Access5830 Subscriber Unit (SU/CPE).
Other than the obvious hardware differences, the TrangoFOX SU differs from the Access5830 SU in the following areas:
- TrangoFOX with internal antenna has 5.8 GHz range of 4 miles vs. 6 miles for Access5830 SU.
- TrangoFOX radios are not dual-band. They are available as either 5.8 GHz or 5.3 GHz.
- TrangoFOX does not have a serial port.
- TrangoFOX features a IP/Password reset button.
- TrangoFOX has 4 alignment LEDs
- TrangoFOX with internal antenna has azimuth beamwidth of 30° vs. 18° for Access5830 SU.
CIR stands for Committed Information Rate and MIR stands for Maximum Information Rate. CIR is the minimum bandwidth to be allocated to a given subscriber unit (SU). If there is idle bandwidth available on the access point (AP), then any given SU's bandwidth can go as high as its MIR. CIR and MIR are specified at the AP in the subscriber database.
Trango has developed a patentet adaptive algorithm called SMARTPolling™ that breaks up 1 second into much smaller intervals of time and during those intervals it polls each SU to check if the Commited Information Rate (CIR) is being satisfied. If the CIR is not being used, any unused bandwidth goes into the overall bandwidth pool and other SUs have the opportunity to use this bandwidth. SMARTPolling™ also feature Dynamic RF Packet Sizing which allows the optimal use of bandwidth per sector/cell.
Power leveling is a feature that allows the AP to maintain the same radio signal reception level of multiple SU's regardless of the distance between the AP and each SU. Power leveling is achieved by automatically turning up the power for the units that are farther away from the AP and turning down the power for the units that are closer to the AP. The AP will perform power leveling with all the SU(s) in a sector automatically when they try to associate with it. Manual power leveling is needed after issuing an su restart or SU reboot command from the AP. This feature reduces interference between the cells.
The Access5830 Broadband Access system provides inherent security features due to its proprietary design. For a more detailed discussion of data security on the Access5800 and 5830, see Security Features of Access5830 - Broadband Wireless Access System.
This table consists of a list of channels and the corresponding polarization the SU will try to communicate with the AP(s) after its link with an AP is lost. There is a switch called Auto Scan at the SU to enable/disable this feature. The first channel with polarization in the scan table is used when the SU is powered on.
CIR and MIR settings can be used to limit bandwidth to specific subscriber units.
You will see 0 throughput and 20.0.0 on the SU
Most Ethernet broadcast packets can be blocked from either direction, AP to SU or SU to AP, to reduce the non-payload traffic with the exception of ARP and DHCP packets. This feature is meant to improve network performance. There is a switch called Block Broadcast Packet at both the AP and the SU to enable/disable this feature. The factory default is on.
