Abstract
Synchronized UWB piconets for SOP (Simultaneously Operating Piconet) performance. A common backbone (either wired or wireless) is employed that provides a common CLK (clock signal) to all of the various PNCs (piconet coordinators) of various piconets that may operate within a sufficiently close region such that interference could undesirably occur. By providing a very reliable CLK signal from a common backbone to all of the PNCs of the various piconets operating within a substantially close proximity to one another, very precise synchronization may be ensured for all of the communications performed therein. The various piconets may then even operate using TDMA (Time Division Multiple Access)—whose performance would be substantially compromised without effective synchronization. In addition, combined TFC (time frequency code) and TDMA may also be employed to support the communications therein thereby providing even another degree of orthogonality that provided by TDMA alone.
