ABSTRACT:
The cellular system for transmitting information by radio between an infrastructure and mobiles constrained to travel on a determined path comprises stationary transceiver stations and at least one transceiver carried by each mobile, which transceivers are controlled in such a manner that, while a mobile is in a given cell, exchanges between the mobile and the transceivers allocated to the cell take place on two different frequencies in alternation during two successive radio cycles.
