1. A method of communication between a network hub and at least one network node based on transmitting from the network hub a beacon signal, comprising:
transmitting a beacon frame, corresponding to the beacon signal, during a beacon period, the beacon period beginning at a beacon period reoccurring time;
the beacon frame identifying a beacon shifting sequence index and a beacon shifting sequence phase;
the beacon shifting sequence index:
identifying a specific beacon shifting sequence corresponding to a repeating beacon shifting sequence pattern as a series of beacon shifting sequence phases, each beacon shifting sequence phase
indicating a position within the beacon shifting sequence pattern, and
corresponding to a transmission time offset within the beacon period;
wherein the beacon shifting sequence pattern is a repeating PN (pseudo-random number) sequence selected from: 0,0,0,0, . . . ; 0,1,0,1, . . . ; 0,2,0,2, . . . ; 0,1,2,3, . . . ; 0,1,3,2, . . . ; 0,2,1,3 . . . ; 0,2,3,1, . . . ; 0,3,1,2, . . . ; 0,3,2,1 . . . ;
using a current beacon shifting sequence designated by a current beacon shifting sequence index; and
transmitting the beacon frame in a specific beacon period according to the current beacon shifting sequence based on:
determining a current beacon shifting sequence phase for the beacon frame,
determining a current beacon transmission time offset corresponding to the current beacon shifting sequence and the current beacon shifting sequence phase, and
transmitting the beacon frame at a beacon frame transmission time delayed after the beacon period recurring time by the current beacon transmission time offset,
wherein the beacon frame includes
the current beacon shifting sequence index corresponding to the current beacon shifting sequence, and
the current beacon shifting sequence phase.
