Abstract

A PDA telephone comprises a wireless headset and a main hand-held unit. The wireless headset includes a first wireless transceiver, a speaker, and a microphone. The speaker and the microphone are coupled to the first wireless transceiver. The hand-held unit receives, processes, and displays personal organizer information. The hand-held unit includes a second wireless transceiver, an antenna, and wireless telephony circuitry coupled to the second wireless transceiver and the antenna. The hand-held unit is free of a telephone speaker and a telephone microphone. The second wireless transceiver transmits incoming audio signals to and receives outgoing audio signals from the first wireless transceiver. By eliminating the speaker and the microphone from the hand-held unit and instead incorporating these items in the wireless headset, the size, weight, cost, complexity, and convenience and efficiency of use of the PDA telephone are optimized.

Claims
