Evaluation of Co-existence interference between CDMA 1900MHz & WCDMA 2100MHz

[riyantoyadi]

Spectrum is a scarce resource and with increase in tele-density and subscriber numbers, there is
need for additional spectrum. In the 1900MHz band, there is an overlap of spectrum (1930MHz-
1980MHz) between CDMA & WCDMA systems. However, there is 1900MHz-1910MHz paired
with 1980MHz -1990MHz band that is exclusively used by CDMA/EVDO.
There are deployments in the 1900MHz band for WCDMA & CDMA systems [Example:
Philippines]. Coexistence of different cellular communication systems that share the same
frequency band is becoming one of the most efficient ways to use the spectrum

Thanks n Rep still needed

very good to know abaout interference
