FIELD: wireless communications.
SUBSTANCE: invention relates to wireless communication. Electronic key conveyance system (10) of medical institution (14) includes control point (70). Control point (70) receives one or more electronic keys from coordinator (12) of an MBAN spectrum. Each of the electronic keys authorizes medical institution (14) to use, at least, portion of the MBAN spectrum. System (10) further includes channel regulator (72) generating by processor (80) one or more channel use rules based on the electronic keys. Channel use rules authorize MBAN systems (18, 20, 22) of medical institution (14) to use at least, portion of the MBAN spectrum. Besides, System (10) includes one or more access points and/or ports (74, 76) notifying MBAN systems (18, 20, 22) of presently authorized portions of the MBAN spectrum based on the channel use rules. Electronic key is based on the available spectrum of primary users, like AMT, rules are based on a key and the spectrum already occupied by other MBANs and their nodes. Frequency range of used 802.15.4j is 2,360 MHz to 2,390 MHz or 2,360 MHz to 2,400 MHz. Cognitive radio principles are applied.
EFFECT: technical result is transmitting electronic keys for in-hospital MBAN (medical body area network) systems.
