Frequency-plan for a frequency-hopped mobile cellular radio-communication system

摘要

The system includes an operation and maintenance centre which uses software to transmit the frequency plan to be applied on the ground to the various controllers. Each controller is in charge of a predetermined group of base stations via wire channels. The controls are driven so the correct frequencies are assigned to each cell, according to the pattern which the cell is in. At each base station the adapted controls are connected to a transceiver. The frequency plan is a superposition of those belonging to several systems, which each have a different number of cells per pattern.
