Abstract

Any sharing between future public land mobile telecommunication systems (FPLMTS) and fixed services must be on the basis of maintaining high reliability and performance for both services. The focus of this article is to examine the following. Can mobile and fixed systems share the same frequency band? How much unwanted signal power is received by each system from the other? How does the unwanted signal power vary as mobile users roam in an area covered by the main-beam and the sidelobes of the fixed service? What effects do the parameters of FPLMTS (transmitter power, bandwidth, etc.) and the parameters of the fixed service (antenna directivity, power, bandwidth, etc.) have on the unwanted signal power levels? How is the unwanted power level affected by the path geometry, in particular fixed service antenna height and propagation conditions (congested areas) between the mobile and fixed stations?.<>
