Abstract

A personal area network (13) includes a plurality of wireless medical devices (12) which monitors physiological patient data and/or deliver therapy to the patient. The medical devices (12)each include a location management module (46) which controls a transceiver (40) to operate according to a operating profile associated with the geographical region in which the devices (12) currently reside. The operating profiles include at least one of transmission frequency, duty cycle, and maximum transmit power as mandated by local regulatory requirements. A wireless hub (10), as part of the personal area network (13), communicates with the wireless medical devices (12) and interfaces them with an infrastructure network (30). The hub (10) includes a location management module (46′) which receives a current geographical position and determines the corresponding geographical region and retrieves an operating profile(s) associated with the region. The hub advertises the operating profile to the wireless medical devices (12).

Claims
