— Transmitter power control has proven to be an efficient method to control interference and to improve spectrum utilization in cellular and personal communication systems. Previous results have shown that a significantly higher capacity may be reached, even if the system is subject to (practical) power constraints. Since in most cellular systems a duplex link is required, adequate transmission...

This paper presents a c omparison of channel allocation schemes for mobile c ellular networks. Three schemes have been evaluated: Fixed Channel Allocation (FCA), Dynamic Channel Allocation (DCA) and Channel Allocation with Space a nd Time Variations (CA STV). The third scheme uses information about mobile users profiles for getting adaptability to traffic fluctuations. Results were obtained u s...

This paper introduces a joint planning and management optimization approach for cellular networks to limit energy consumption while guaranteeing QoS and minimizing operators Capex and Opex. The modeling framework shows that an effective energy-efficient operation depends on the planning decisions. Conversely, it also shows that planning with energy management operation in view yields more versa...

The cell size in mobile networks is decreasing to accommodate more users in the same bandwidth. Smaller cell sizes increase the number of handoffs between cells and the probability of encountering a cell with more users than the bandwidth can accommodate. Packet techniques can reduce the work that is performed in a handoff and reduce the probability of losing a connection in an over populated c...

− Location Management is the procedure of keeping track of and locating Mobile Terminals (MT’s) in mobile radio communication system so that calls arriving for them can be routed correctly to their current location. The main aim of the Location Management is to track the MT’s using minimum overhead traffic. Since the radio bandwidth is a scarce resource in mobile radio communication systems, it...

In cellular communications there are two primary communication links between the cell’s central basestation and the users, the uplink (or reverse link) and the downlink (or forward link). The former refers to the flow of information from the users to the basestation, and is a problem which has been and is still today the subject of much debate. The downlink, however, receives less attention, si...
