Abstract
A wireless communication method and protocol for wireless RF transmission of audio data from a plurality of wireless RF devices (portable parts PP) to a wireless RF receiver device (fixed part FP) using a full slot DECT protocol. The FP broadcasts in each frame, a multiplex of control information to the plurality of PPs. The PPs receive the multiplex of control information, and extract control information intended for each individual PP from the multiplex of control information. Preferably, the PPs are synchronized to transmit audio data in respective time slots covering both time slots in first and second half of the frame. This allows a high number of PPs to be connected to one FP still at a high audio quality with low latency, since both the normal uplink and downlink parts of the DECT frame are used for audio data transmission. This allows the method to be used for a conference call system of a high number of wireless microphone devices, or a live performance wireless microphone and/or musical instrument sound system or the like.
