Teletraffic characteristics of cellular communication for different types of vehicle motion

The cellular-communication systems of the future will be required to provid e multimedia services to users moving about in a variety of ways (on foot, in automobiles etc). Different forms of motion have different characteristi cs. The characterization of the different forms of motion and their effects on telecommunications traffic is important in the planning, design and ope ration of mobile communication networks. The characterization of the motion of various platform types (inter-city buses, recreational vehicles, freigh t trucks, and taxis) based on measurements using Global Positioning System is presented in this paper. The measured characteristics of motion are then used to evaluate teletraffic statistics such as cell cross-over rate and c ell dwell time by overlaying hypothetical cell systems on the measured loci of vehicles. Self-similarity was discovered in the cell dwell time charact eristic of the taxis.
