Interference Potential of FSS and BWA on the Extended C-Band
Abstract: The Indonesian
government has allocated the 3.3-3.4 GHz band, which is adjacent to the
extended C-band 3.4-3.7 GHz, for Broadband Wireless Access (BWA) services. The
country has been using the extended C-band for Fixed Satellite Service (FSS).
This research shows the interference potential between the two systems if an
adjacent band is allocated for them. Using a clutter loss of 10 dB and site shielding
of 40 dB, a BWA network consisting of 57 base-stations will potentially
intefere an FSS with probability 56.16% if the protection distance used is 1.55
km. The interference potential will decrease to 0% if the protection distance
is increased to 3 km. With a BWA network consisting of 20 base-stations, the
interference probability is 10.72% and 0% for a protection distance of 1.55 km
and 2 km, respectively. With this
interference potential it is urgent that Indonesia enforces interference
mitigation techniques to protect FSS from disruptive interference.
