Ultra Wideband (UWB) technology developer Pulse-LINK, today announced the development of UWB over-wire applications. According to Pulse-Link, this effectively doubles the bandwidth available to Cable Television (CATV) systems with data capacities exceeding one gigabit. The development of UWB-Cable is an application that functions within recently approved (2/14/02) FCC parameters for ultra wideband, which were designed to be initially conservative to avoid interference.
Pulse-LINK stated that the use of UWB in this particular application requires no modification of existing cable infrastructures. It is designed to function over existing wired infrastructures without interference or degradation to TV, data and voice services. Pulse-LINK said that using UWB in this manner can enable such applications as High Definition TV (HDTV), Video-on-Demand (VoD), Interactive Television(iTV), T-Commerce (Television Commerce), Gaming, Voice over IP (VoIP), and substantially increased Internet bandwidth over cable.
"Ultra Wideband technology is not just for wireless communications anymore," states Bruce Watkins, President and COO of the San Diego-based Pulse-LINK. Although the two-year old company continues to be a leader in the development of UWB technology for wireless communications, Pulse~LINK's over-wire technology offers immediate application of UWB. "We believe we are the only company with an extensive body of Intellectual Property in the over-wire application of UWB technology and have been extremely tight-lipped about this innovation until our foundation Patent Portfolio was completely in place." The Company anticipates its UWB wired and wireless technologies integrating perfectly to provide a seamless broadband delivery and networking experience throughout the home and office.
Pulse~LINK Founder and Chief Technology Officer John Santhoff states, "Pulse~LINK's UWB over-cable initiative is a direct outgrowth of our UWB wireless efforts. The amount of bandwidth that this technology is capable of delivering over wired media has exceeded our original expectations. We are very excited and look to see this technology applied in many ways never envisioned for UWB." He adds, "Given the fact that multi-billion dollar wired industries already exist while wireless is still in its infancy and crowded with competing technologies, we are extremely happy to be bringing our exclusive UWB over-wire technology to market now. The wired and wireless versions of UWB are perfect complements to each other."
Pulse~LINK reported that it is currently conducting ongoing demonstrations for potential partners of its Pulse~LINK UWB-Cable to validate its technology for use across existing Hybrid Fiber Coax System (HFCS) architectures used by the cable television industry. UWB-Cable signals are introduced using inexpensive equipment at the cable head-end and extracted at the customer premises with end user-installed equipment that operates seamlessly with most existing and deployed digital set-top boxes. The Pulse~LINK technology does not interfere with or degrade television, high-speed Internet, voice or other services already provided or projected by the CATV industry. Existing CATV networks supply information and content using signals referenced in the frequency domain. CATV channels typically occupy 6 MHz in the US and 8 MHz in Europe.
Pulse~LINK UWB-Cable supports international standards for cable television such as NTSC, PAL and SECAM. The Pulse~LINK UWB-Cable technology could enable the means of bringing digital bandwidth to over two hundred fifty million cable subscribers on older legacy systems worldwide.
Ultra Wideband is a means of tranmitting data that does not use an RF Carrier for its signal. Data is transmitted using time and amplitude modulated pulses of less than one nanosecond in duration. UWB proponents emphatically state that the technology can co-exist with carrier frequencies without interference. The technology currently can deliver hundreds of megabits of data, with theoretical capacity in the Gigabit range. The broad spectral nature of UWB pulses also allows these wireless communications to penetrate walls and obstacles better than existing technologies that are based on narrow bands of carrier frequency, and the extremely short timing between UWB pulses can provide positional accuracy on UWB devices to within one-centimeter resolution.
Pulse~LINK, Inc. was founded in June, 2000. The Company has almost eighty issued and pending patents pertaining to Ultra Wideband wired and wireless communications technology. In May, 2001, Pulse~LINK acquired the assets and intellectual property of another Ultra Wideband technology company, Fantasma Networks, which was located in Silicon Valley.
