Patent ID: 6842623

Claim:
A wireless unit comprising: a first communication port; a communication port controller responsive to first data received at said first communication port to buffer said first data; a second communication port configured to couple to an audio input line; a codec responsive to a sampling interrupt to generate a audio sample from available audio data received at said second communication port; a wireless modem responsive to a first signal to encode said first data in a first frame, wherein said first signal is derived from command data received at said communication port, and wherein said wireless modem is responsive to a second signal to encode said audio sample in a second frame; an a radio transceiver responsive to said first signal and to a frame interrupt to transmit a first RF signal frame representing said first frame, and responsive to said second signal and to said frame interrupt to consecutively transmit a second RF signal frame representing said second frame, said radio transceiver receiving no RF signal between said transmission of said first and second RF signal frames.
