Broadband Physics Awarded Patent for Sub-band Division Multiplexing

Broadband Physics, a fables semiconductor start-up based in Cupertino, California, was awarded a U.S. patent entitled “Method and Apparatus for Signal Transmission And Reception” for its novel approach of using wavelet mathematics for Sub-band Division Multiplexing, a new digital signal transmission ‘modulation’ method. The company said Sub-band Division Multiplexing (SDM) is suited for select physical environments that either need to “mine” more digital capacity from existing last mile networks. Examples include 180+Mbps digital channel speeds over cable networks, for the same costs as today’s 30Mbps digital channels; or where dynamic software controlled use of RF passpands, notches, power, and digital capacity flexibility is needed to meet many different provisioning scenarios or changing environments, such as power line communications, select twisted pair applications, wireless, and potential future Ultra Wide Band (UWB) scenarios.
