FWA interference management: co-channel, PCI conflicts

Co-Channel Interference in FWA

Co-channel interference occurs when neighboring cells transmit on the same frequency, creating overlapping coverage zones where signals compete. FWA subscribers at cell edges are particularly vulnerable because they receive comparable signal strength from multiple cells. Unlike mobile users who move through interference zones, FWA CPE remains stationary in a potentially poor location permanently. Inter-cell interference coordination techniques help by scheduling transmissions on different time-frequency resources in overlapping zones. Advanced methods use coordinated beamforming to steer…
