Gps Gsm Antenna
Why GPS antenna is used in CDMA network and not in GSM network ?.?
other than sync. purpose
CDMA technology works on spread spectrum, It is not FDMA / TDMA for differentiating customer sigmals , it uses noise .. ie, Each individual signal is sampled with a walsh code or PN code on a real time basis… since clock is a very important factor it needs to have a backup clock sync .. so in cases the clock from the MSC is intrupted by any means , the CDMA BTS will use the GPS to provide alternate clock sync… Thats why only cdma n/w has GPS receiver
