Abstract
A mobile telecommuncations system has multiple base stations each defining a miniature service zone and capable of communicating with mobile stations present in the service zone over a radio link. Geographically associated ones of the base stations are spaced apart from each other by an area which is not responsive to electromagnetic waves on the radio links, whereby the base stations are allowed to share the same frequency for the electromagnetic waves. The base stations are interconnected to an on-road vehicle telecommunications network which switches communications to the base stations.
