SIR Estimation in Hexagonal Cellular Networks With Best Server Policy
The evaluation of the Signal to Interference Ratio (SIR) in cellular networks is of primary importance for network dimensioning. For static studies, which evaluate cell capacity and coverage, as well as for dynamic studies, which consider arrivals and departures of Mobile Stations (MS), the SIR is always an important input. Contrary to most of the analytical works evaluating SIR, the authors assume in this paper that the MS is attached to the best server, i.e., to the Base Station (BS) from which it receives the highest power. This is a more realistic policy compared to the classical one that considers MSs to be attached to the nearest BS.
