A medical system includes one or more medical body area network (MBAN) systems. Each MBAN system includes one or more MBAN devices which acquire and communicate patient data with a hub device via short-range wireless communication. The communication of the patient data via the short-range wireless communication is within a predefined spectrum. The hub device receives patient data communicated from the one or more MBAN devices and communicates with a central monitoring station via a longer range communication. A MBAN channelization scheme defines one or more overlapping channels in the predefined spectrum and a MAC parameter dynamically enables or disables access to each defined channel. A channel regulator manages the MBAN utilization of the predefined spectrum by setting the MAC parameter to dynamically enable/disable the one or more predefined MBAN channels within the predefined spectrum.
