Abstract
Devices of a personal area network (PAN) use a wireless medium that is shared with a wireless local area network (WLAN). WLAN devices communicate using protocols of the WLAN and PAN devices communicate using PAN protocols allowing for lower power transmissions over the wireless medium relative to transmissions over the WLAN. A PAN coordinator device obtains access to the wireless medium for the PAN devices by signalling a reservation of the medium by the PAN coordinator device, such that the other devices defer use of the wireless medium, including at least one WLAN device, for a reservation period. During the reservation period, the communication is done using the PAN protocol. The signalling can be implicit in that the PAN coordinator device transmits one or more frame using the PAN protocol but that is at least partially understandable by WLAN devices such that they defer upon receipt of one or more of the PAN protocol frames, which may be a standard or modified HCCA-CF poll frame, a CTS frame with an increased duration field, or other variation. A PAN coordinator might also signal an access point to set up a DLS link between the PAN coordinator and itself and use the DLS period for PAN traffic.
