Methods and apparatus for combined wireless telephony and data communication
of the present invention include providing a Home RF transceiver and a WDCT transceiver
in a common enclosure and synchronizing the operation of the Home RF transceiver
to specific time slots in the WDCT TDM frame. More particularly, the Home RF transceiver
is prevented from transmitting whenever the WDCT transceiver is receiving and is
prevented from receiving whenever the WDCT transceiver is transmitting. This effectively
prevents the Home RF transceiver from interfering with the WDCT transceiver and
vice versa. According to a presently preferred embodiment, synchronization is keyed
to the repeating WDCT TDM frame but is dynamically adjustable based on the actual
use of bandwidth by the WDCT devices. Thus, when there is no telephony traffic,
the Home RF transceiver has full bandwidth. For each WDCT telephone call in progress,
no more than 1/12 of the Home RF transceiver bandwidth is sacrificed. The methods
and apparatus of the invention allow the reuse of key components from existing
standards to provide a combined voice and data base station. The invention also
takes advantage of two proven technologies to achieve its goals.
