Abstract: A coordinator switching method and corresponding apparatus (20) are provided. One or more candidate coordinators (64) to replace a coordinator (20) of a medical body area network (MBAN) (22) are identified. The coordinator (20) is associated with one or more devices (16, 18) of the MBAN (22). One of the identified candidate coordinators (64) is selected as a destination coordinator. The destination coordinator (64) is requested to replace the coordinator (20) and allocate resources for the devices (16, 18). Acceptance of the request and data identifying the allocated resources for the devices (16, 18) is received from the destination coordinator (64). The devices (16, 18) are instructed to associate with the destination coordinator (64) using the allocated resources.

Abstract: A personal area network (PAN) coordinator (26) of a medical body area network (MBAN) (36) allocates multi-periodic guaranteed time slots (GTSs) to sensor devices (12, 14) of the MBAN (36). The PAN coordinator (26) includes a controller (40) configured to receive a request for a multi-periodic GTS from a sensor device (12, 14) of the MBAN (36). The request includes a period indicating a periodicity with which the multi-periodic GTS is requested. In response to the request, the controller (40) determines a GTS allocation including a starting frame and transmits a descriptor to the sensor device (12, 14). The descriptor includes information to identify the starting frame.

Abstract: A receiver is arranged to receive at least two RF signals (51,52). A first RF signal of the at least two radio frequency signals (S] 5S2) is having a first center frequency, whilst a second signal of the at least two RF radio frequency signals (si,s2) is having a second center frequency, the receiver comprises a frequency shifter (10,11) arranged to shift the first center frequency to the second center frequency and a combiner (12) arranged to combine the frequency shifted first RF signal (S3) with the second RF signal (si) so as to obtain a combined RF signal (s4). The receiver further comprising a frequency down converter (15,16) arranged to frequency down convert the combined RF signal (s4) to a combined lower frequency signal and a demodulator (19) arranged to demodulate the combined lower frequency signal.
