UWB - Over Cable TV

802 Planet reports that at the annual CableLabs Summer Conference earlier this month in Keystone, Colorado, ultrawideband (UWB) chipset developer Pulse~LINK showcased its technology for cable operators.

Pulse~LINK transmits high definition television content over cable and powerline. "It transmits across the entire cable bandwidth -- not wirelessly -- showing that it coexists with the television signals that are already there," said PulseLINK representatives.

The demonstration consisted of industry standard off-the-shelf CATV equipment beginning at the ìCable Operatorís head-endî where the UWB signal was injected into a standard RF combiner, then modulated onto a fiber optic cable for transmission to a ìfiber field nodeî where the
RF content was demodulated for transmission through more than 1000 feet of coax cable and two ìfield amplifiers.î

The signal was then sent through multiple RF splitters and into a ìdigital living roomî where both the UWB HDTV broadcasts and standard cable broadcasts were displayed simultaneously.
