example B

[0130] At decision block 704, the processor 116 determines whether the next instance B(i) of the beacon signal is sent via the wireless unit 122'. The central node 106 may periodically (via the wireless unit 122' and the wireless interface 122") transmit instances of the non-hopping beacon signal B. Each instance of the beacon signal B(i) may include: a frame of frames corresponding to it number FN(i); and the identification IDCN of the central node 106. Again, the frame tracker 136 can be configured to determine the frame number FN(i). The beacon signal generator 134 can be configured to receive the frame number FN(i) , and periodically generate an instance B(i) of the non-hopping beacon signal B(i), which includes: the frame number FN(i); and the identity IDCN of the central node 106 .

[0131] If the result of decision block 704 is "No" (the next instance B(i) of the beacon signal is not sent), processor 116 waits, eg, flow loops back to the input of decision block 702 . I...

Abstract

The invention relates to a method (for operating an end node). The method comprises: wirelessly receiving an instance B of a non-hopping beacon signal periodically transmitted from a central node; interpreting a block frequency hopping guide (FBHG) according to FN(i) and IDCN, thereby determining that during frame FN(i) A respective set CSET(i) of at least two channels through which an instance of an end node may transmit, respectively; at least pseudo-randomly select at least one channel in said set CSET(i); and utilize said at least one selected A channel wirelessly transmits at least one message from the end node. Each instance B(i) includes: a corresponding frame number FN(i); and the IDCN of the central node. The FBHG establishes: a total of L frames; a channel set CSET for each frame, respectively; and for any two consecutive frames FN(j) and FN(j+1) in the L frames, the corresponding set CSET(j) It is different from CSET(j+1), CSET(j)≠CSET(j+1).
