Resumo(s)
The maximisation of system capacity in Mobile Broadband Systems (MBSs) is addressed via an approach for traffic analysis that considers different scenarios for the mobility of terminals and two different types of services: short and long duration ones. For short duration services, the maximum of the new calls traffic linear density occurs for the typical coverage distances, R, of MBS, i.e., 100-350 m, except for the highways scenario, where it occurs for R = 500 m. However, for long duration services, these maxima are obtained for Rs approximately four times the previous values, new calls traffic linear density being 16% lower; feasible values, lower than the optimum ones, are obtained for lower coverage distances in high mobility scenarios. The use of guard channels for handover improves system performance only for short duration services, 2 being the recommended value for the number of guard channels in the considered cases.
