An electronic key conveyance system (10) of a medical institution (14) includes a control point (70). The control point (70) receives one or more electronic keys from a coordinator (12) of an MBAN spectrum. Each of the electronic keys authorizes the medical institution (14) to use at least a portion of the MBAN spectrum. The system (10) further includes a channel regulator (72) generating by a processor (80) one or more channel use rules based on the electronic keys. The channel use rules authorize MBAN systems (18, 20, 22) of the medical institution (14) to use the at least a portion of the MBAN spectrum. Even more, the system (10) includes one or more access points and/or ports (74, 76) notifying the MBAN systems (18, 20, 22) of presently authorized portions of the MBAN spectrum based on the channel use rules. The electronic key is based on the available spectrum of primary users like AMT, the rules are based on a key and the spectrum already occupied by other MBANs and their nodes. The frequency range of used 802.15.4j is 2360 MHz to 2390 MHz or 2360 MHz to 2400 MHz. Cognitive radio principles are applied.
