ABSTRACT:
A wireless communication system capable of communicating by a frequency hopping method, includes a base unit that can be connected to an external telephone circuit and multiple handsets that can communicate wirelessly with the base unit. A hopping table of the base unit stores a hop frequency data array B for communications between the base unit and a selected handset. A hopping table of each handset stores hot frequency data arrays H1 and H2 for communications between two handsets in addition to the hop frequency data array B possessed by the based unit. During communications between the base unit and a handset, communications between handsets are possible by using the hop frequency data arrays H1, H2.
