Abstract
Official abstract text for this publication.
A system and method for minimizing or preventing interference between wireless networks is disclosed. A network hub broadcasts a beacon signal within repeating beacon periods. The position of the beacon signal shifts within each beacon period based upon a predetermined pseudo-random sequence. The beacon signal includes data identifying the current beacon shift sequence and the current phase of the sequence. Neighboring hubs independently or jointly determine and broadcast their own beacon shift sequences and phases for their respective networks from a predetermined list. Nodes connected with the network hubs are assigned allocation intervals having a start time that is set relative to the beacon signal. The start time and duration of the allocation interval wraps around the beacon period if the allocation-interval would otherwise start or continue in a next beacon period.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for transmitting a beacon signal, comprising: generating a beacon frame to be transmitted in a beacon period, the beacon period beginning at a beacon period reoccurring time, the beacon frame comprising a beacon shifting sequence identifier and a beacon shifting sequence phase, the beacon shifting sequence identifier indicating a specific beacon shifting sequence comprising a repeating series of beacon transmission time offsets, and the beacon shift…
