Claim:
1. A system comprising: at least two wireless sensor devices positioned to monitor a physiological data of a patient; a gateway device in communication with the at least two wireless sensor devices, the at least two wireless sensor devices and the gateway device forming a wireless body area network; the gateway device configured to provide time synchronization signals to the at least two wireless sensor devices, the time synchronization signals adhering to a dual-frequency adaptive protocol, wherein the gateway device ranks frequency channels based on quality, wherein the rank includes a predictive model that provides an expected performance of each frequency channel; the time synchronization signals including a communication frame structure having a plurality of time slots including two beacon signal time slots and a plurality of data slots; each of the at least two wireless sensor devices configured to transmit respective patient data a first time interleaved within a same first one of the plurality of data slots; and each of the at least two wireless sensor devices configured to transmit respective patient data a second time interleaved within a same second one of the plurality of data slots; wherein a frequency offset is determined by a communication transceiver within the wireless sensor devices as based on a selectivity response characteristic of an internal receiver, the selectivity response characteristic providing a minimum difference in signal strength between a desired signal at a frequency Fa within a wireless body area network (WBAN) and an interfering signal at a frequency Fb from an interfering WBAN at the internal receiver.
