Factory default Configuration
From the factory, the APs/BHMs and SMs/BHSs are all configured to
not transmit
on any frequency. This
configuration ensures that equipment operators do not accidentally turn on an unsynchronized module.
Site synchronization of modules is required because
modules:
o
cannot transmit and receive signals at the same time.
o
use TDD (Time Division Duplexing) to distribute signal access of the downlink and uplink frames.
when one module transmits while an unintended module nearby receives signal, the transmitting
module may interfere with or desense the receiving module. In this context, interference is self-
interference (within the same network).
