Influence of handover hysteresis on bitrate in LTE network

Konrad Połys

Abstract


In wireless networks users are switched between base station basing on signal strength or other metrics. To optimize users’ handover between base stations commonly used is hysteresis. It reduces the number of unnecessary, very short handovers. In this paper we have evaluated influence of handover hysteresis on the number of handovers and average bitrate which is derived from signal-to-noise ratio. The results show that proper handover margin can notably reduce the number of unnecessary handovers almost without reducing the throughput of network.
