CED Broadband Direct:

Broadband Physics, a silicon start-up based in Cupertino, Calif., is focusing its engineering efforts on providing fiber speeds over legacy “last mile” broadband access networks via a modulation scheme called sub-band division multiplexing. SDM leverages Wavelet Mathematics for multi-sub-band signaling, a technique that divides RF spectrum into multiple, equal-sized sub-bands. The result, the company claims, is a digital capacity boost of more than 200 percent compared to existing solutions in “select” last-mile applications, and at one-third the cost.

Broadband Physics said the technology, which targets cable, wireless and satellite networks, entered into its technical execution phase last month. The company demonstrated a working prototype in the lab last year.
