Abstract :
We present a study of the signal-to-interference-plus-noise ratio and throughput efficiency achievable in a multicellular environment in the presence of smart antennas at the base station receivers. Interference is explicitly taken into account, and different cases are compared. It is seen that the system operates most efficiently with full frequency reuse, even though this requires network-wide synchronism. The effect of lack of synchronization is also studied
