UWB is not limited to RF applications. Work is already under way to demonstrate UWB over coaxial cables. Because coax is a shielded media, FCC spectral restrictions do not apply. Early results suggest maximum data rates of 2 Gbps over 1500 to 2000 feet of cable and through repeaters. If successful, UWB could ride over the existing infrastructure, with data rates up to a few gigabits per second, without interfering with legacy connections. Work with twisted-pair (that becomes an antenna) demonstrates 10 Mbps to 30 Mbps over as much as 20,000 feet. Another application for UWB wireless LANs is cable TV distribution throughout the home.
