Frequency Bands File and Frequency Bands
Groups
The Frequency Bands Configuration file defines the characteristics of each of the
frequency bands supported by the system. These characteristics include:
Lowest Downlink Frequency
Highest Downlink Frequency
Step (resolution)
Duplex Separation: the difference between downlink (Tx) and uplink (Rx)
frequencies.
Group ID: For certain bands, the relevant SU may use a frequency band that
includes more than one of the discrete bands available for the ODU. The
Group ID defines the Frequency Bands Group, which includes frequency
bands that can be used by SUs served by the ODU using the selected band.
The Frequency Bands Group defines also the range of frequencies that can be
used by the relevant AU.
In the current release, the following Frequency Bands are supported:
