Patent ID: 8670380

Claim:
An apparatus comprising: a plurality of portable wireless transmitter units; a plurality of digital receiver modules that alternate transmitting wireless synchronization pulses and that receive information from the plurality of portable wireless transmitter units synchronized to the synchronization pulses; a receiver control unit in communication with each of the receiver modules that coordinates transmission of synchronization pulses among the plurality of digital receiver modules in accordance with a predetermined transmission sequence; and a system that receives the information from at least some of the transmitter units through the receiver modules and delivers the information exclusively to an intended predetermined destination wherein each of the plurality of portable transmitter units operate under a common time division multiple access (TDMA) format within a repeating frame defined by the alternating wireless synchronization pulses from each of the plurality of digital receiver modules, wherein each of the plurality of portable transmitter units is assigned to a respective slot of the repeating frame, wherein the receiver control unit receives audio packets within the respective assigned slot from each of the plurality of portable transmitter units through each of the plurality of digital receiver modules and dynamically selects the digital receiver module providing audio packets with the smallest relative number of errors by comparing a bit error rate through each of the plurality of digital receiver modules from each of the plurality of portable transmitter units.
