Aspects of the invention relate to a system and a method for monitoring health of a patient by using wireless sensor devices positioned to monitor one or more physiological parameters of the patient, and a gateway device in wireless communication with the wireless sensor devices, the wireless sensor devices and the gateway device forming a wireless body area network. The gateway device includes two or more radio frequency integrated circuits (RFICs) connected in at least a series or a parallel connection and provides multiple frequency channels for receiving sensor data from the wireless sensor devices, where the sensor data is transmitted based on time synchronization signals and an multi-channel adaptive protocol.
