Abstract:
1. A method of enabling a plurality of systems ( 300 - 1 , 300 - 2 , 300 - 3 ) to communicate over a common communication channel wherein each system ( 300 - 1 , 300 - 2 , 300 - 3 ) is configured to enable communication during periodic and essentially temporally contiguous respective frame periods ( 409 - 1 , 409 - 2 , 409 - 3 ) determined essentially asynchronously by each said respective system ( 300 - 1 , 300 - 2 , 300 - 3 ) and having occupied temporal portions of each said frame period ( 409 - 1 , 409 - 2 , 409 - 3 ) comprised of transmission communication periods dedicated to each said respective system ( 300 - 1 , 300 - 2 , 300 - 3 ) and wherein each said frame period ( 409 - 1 , 409 - 2 , 409 - 3 ) has a start and an end that essentially spans the entire temporal bandwidth of said common communication channel, said method comprising the steps of: transmitting during each said frame period ( wherein said step of transmitting at least one type of beacon message additionally comprises the step of transmitting at least one wandering beacon message having a moveable temporal offset from the start of its respective frame period; receiving beacon messages ( processing two or more of said received heavily-coded beacon marker code portions ( determining which received beacon messages uniquely correspond to other said systems according to uniquely defined temporal displacements between said received wandering beacon messages.
