Abstract

New technology is needed to meet the ever growing demand for wireless services. The cellular packet switch (CPS) has been proposed as a distributed switching architecture capable of handling the increasing needs of high-density personal communication systems. The IEEE 802.6 metropolitan area network (MAN) is a possible candidate for the backbone of the CPS. This paper calculates the capacity of the CPS. Given an available bandwidth, an exact expression for the number of cells supported by an IEEE 802.6 MAN is derived as a function of the protocols and rates of occurrence of call setups, handovers, and registrations. To provide insight into the effect of each user, a model of mobility, shown previously to be realistic for a regular grid of streets (a “Manhattan grid”), provides an accurate estimate of the frequency of handovers and registrations. Numerical examples based on CCIR estimates of traffic show how MAN bandwidth gets divided between user and signaling information and how well the signaling message load is distributed between the various processors that make up the CPS.
