    Sammanfattning : Quality of Service in Mobile Cellular Networks is an increasinglyimportant research field. Society is demanding higher datatransmission rates and better reception than ever before. As the generations of wireless protocols, e.g, 3G-5G, are going toward shigher data rates, their cell range, or reception area is however constantly decreasing. LÄS MER

    Sammanfattning : In telecommunications in general and in GSM in particular, the handover is a feature that guarantees a smooth transition of a call from one base station - that is for the purpose of this project an antenna - to another. In the recent ten years, the amount of data traffic through mobile telecommunications has doubled annually, putting an enormous strain on the network and forcing operators to upgrade with more and more base stations and new features.
