When a network becomes very large or very dense, it will be more exposed to self-interference and the performance of the system starts degrading.
A careful frequency planning can strongly decrease a network’s self-interference. Several techniques can be used to minimize the effect of self-interference.
Several techniques can be used to minimize the effect of self-interference. One of the most effective ways to limit self-interference is with GPS Synchronization. The ePMP ABAB Frequency Reuse Deployment paper outlines the advantages of GPS synchronized networks and describes self-interference scenarios in systems deployed with ABAB 4-sector and 2-channel reuse configurations. The paper suggests specific methods for decreasing self-interference and optimizing performance.
