Multi-mode radio telephone with velocity sensing mode selection
A radio telephone (200) is operable in a cordless telephone system or in a cellular telephone system. The telephone (200) incorporates circuitry to detect user velocity so that when the user travels more quickly the telephone automatically transfers from cordless mode, which is the preferred mode, to cellular mode. This prevents the degeneration in communication quality which frequently occurs when a user of a cordless system travels faster than walking pace.
