Abstract
As the demand for wireless cellular communication services continues to grow, the struggle for a more efficient use of the frequency spectrum still remains an important issue. Through the use of efficient radio resource management (RRM) techniques the performance of cellular systems may be improved, be it in the form of increased capacity or enhanced quality of service. The RRM techniques that will be evaluated in this work are: signal level-based dynamic channel allocation (DCA) and adaptive antennas. The analysis will be done in the context of the GSM/EDGE radio access network and will include: a comparison with other radio resource management techniques, such as random frequency hopping; evaluation of circuit- and packet-switched services; identification of factors that negatively impact performance; and evaluation of the combined performance of DCA and adaptive antennas.
