Broadband Physics, Inc. announces a new class of broadband last mile modulation called Sub-band Division Multiplexing (SDM). SDM provides fiber speed digital capacity over existing last mile and last yard access networks.
SDM is a multi-band approach that divides the frequency spectrum into sub-bands that are inherently highly independent from each other. The processing is at baseband and can be applied to both wired and wireless media. SDM is highly efficient, highly robust, and highly flexible for delivering digital channel capacities well in excess of today's methods at today's or better prices. SDM has major advantages with its simplicity in overcoming real world non-linear impairments that plague other modulation approaches.
SDM is very well suited for select physical environments that either need to "mine" more digital capacity from existing last mile networks, such as 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 passbands, notches, power, and digital capacity need to change with changing environment, such as power line communications, wireless, and Ultra Wide Band (UWB).
"Broadband Physics is enhancing the ability for delivering impressive speeds over last mile broadband networks," comments David Farber, Professor at the University of Pennsylvania and former Chief Technologist for the FCC. "This will pave the digital roadway further and wider that what we have today."
"Broadband Physics' first patent was issued in 1994. It and our subsequent patents cover the entire multi-sub-band family of modulation. Broadband Physics is committed to standardize SDM for applications that select SDM as the preferred signal transmission method," says Mark Laubach, CEO. "We and our partners are making good progress together."
