Abstract
The problems involved in the introduction of MCS-12, NTT's second-generation cellular system, are described. These problems primarily lie in achieving the optimum balance between equipment cost and cell size. Existing design models are suitable for single cellular systems. It was proposed that the subscriber capacity model and the system cost model for single cellular systems can be applied to overlaid systems. Using the models, the optimum balance between cell radius and equipment cost can be determined for an overlaid system, so as to achieve the cheapest cost for each subscriber. If cellular systems are to be overlaid, the question of system compatibility cannot be avoided. The effects of the various compatibility schemes are discussed. A case study details the compatibility of NTT's MCS-L2 with the original MCS-L1 analog system.<>
