Setting the Synchronization ID
Because of OFDM’s superior multipath performance it is possible for the CPE to falsely synchronize
on an AP from a different sector operating at the same frequency. In order to avoid this type of error,
the APs and CPEs of each sector can have one of two possible OFDM synchronization patterns.
These patterns are orthogonal, thus a CPE with a given Synchronization ID will never synch to an AP
with the other synch. Every CPE in the sector must have the same Synchronization ID as the AP of
that sector.
➧
To set the Synchronization ID
1. From the Main System Menu, select
Radio Configuration
and press Enter .
The Radio Configuration menu appears.
2. Select
Synchronization Id [0..1]
and press Enter . The entry field highlights.
3. Type a 0 or 1 to select the Synchronization ID and press Enter . Factory default is zero (0).
4. Reboot the system to effect the changes. See Reboot Current Image , page 60 .
Setting the RF Center Frequency
Libra 5800 equipment uses Time Division Duplexing (TDD). In TDD, the units transmit and receive
on the same frequency. They alternate in time to provide the duplexing capability. The frequency of
these channels depend on the model of equipment used.
