7 GPS Description
This section provides a description of the Global Positioning System (GPS).
Note: Even if there is a single isolated BS with multiple sectors the GPS is
required.
The third-party GPS antenna is a rugged, self-contained GPS receiver and antenna that receives
a universal GPS satellite clock signal. The GPS connects to the BSDU. The GPS synchronizes
(based on frequency hopping) multiple Base Stations, ensuring that the entire Airspan WiMAX
network operates with the same clock based on a universal satellite clock signal. This is crucial in
eliminating radio frequency ghosting effects.
