摘要:
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.

摘要:
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.
