Abstract
A medical body area network (MBAN) system comprises network nodes intercommunicating via short range wireless communication. A primary user database contains information pertaining to usage of a restricted spectrum by primary users wherein the MBAN systems are secondary users of the restricted spectrum. An electronic key generation engine comprises a digital processing device configured to generate an electronic key (E-key) indicative of whether the MBAN system is allowed to use the restricted spectrum based on content of the primary users database. An MBAN application server is configured to distribute the E-key to the MBAN system. The MBAN system includes a spectrum control sub-module comprising a digital processor configured to select an operating channel or frequency for the short range wireless communication based at least in part on whether the E-key authorizes the MBAN system to use the restricted spectrum.
