摘要：
A system includes wireless sensor devices monitoring a patient, a gateway device providing dual-frequency adaptive protocol time synchronization signals to the sensor devices, the time synchronization signals including a communication frame structure having time slots including two beacon signal time slots and a plurality of data slots, where the sensor devices transmit respective patient data a first time interleaved within a first data slot and a second time interleaved within a second data slot, the first interleaved data transmission and the second interleaved data transmission are each transmitted at respective different frequencies provided to the sensor devices in beacon signals received from the gateway device. The first interleaved data transmission includes both current data and previous data from the at least two wireless sensor devices, and a frequency agility pattern separates adjacent channels by a respective predetermined frequency offset. A method and non-transitory medium are disclosed.
