XtremeSpectrum Issued Fundamental Patent for Ultra-wideband, Formally Establishes Industry's Premier Patent Portfolio.Business Editors/High-Tech Writers 2003 International CES Booth #SH210 LAS VEGAS--(BUSINESS WIRE)--Jan. 9, 2003 Core Technology Patent Resolves Industry's Ultra-wideband Ownership Concerns XtremeSpectrum, the leading provider of ultra-wideband chipsets, announced here, at the Consumer Electronics Show (CES), the issuance of its first formal patent with regard to ultra-wideband technology by the United States Patent and Trademark Office The United States Patent and Trademark Office (PTO or USPTO) is an agency in the United States Department of Commerce that provides patent protection to inventors and businesses for their inventions, and trademark registration for product and intellectual property . With patent number 6,505,032 issued on January 7, 2003, and more than 50 U.S. patents issued, allowed or pending, XtremeSpectrum now holds the premier technology patent portfolio within the ultra-wideband industry. This now patented and award-winning technology is being exhibited in a wireless, multi-stream HDTV (High Definition TV) A set of digital television (DTV) standards that offer the highest resolution and sharpest picture. Although some HDTV sets are available in standard (rather square) screen sizes, the overwhelming majority of sets are wide screen, which eliminates demonstration throughout CES (see related press release issued today by XtremeSpectrum). "When we developed our bi-phase modulated, ultra-wideband technology, we knew that, while it was a different approach than any other company had taken, it was technically superior for high-data rate, multimedia communications," said Martin Rofheart, CEO (1) (Chief Executive Officer) The highest individual in command of an organization. Typically the president of the company, the CEO reports to the Chairman of the Board. of XtremeSpectrum. "Over the past year, many companies have reached the same conclusion and are now implementing bi-phase modulated ultra-wideband products. Many customers have questioned whom in the industry holds the fundamental patents related to commercial ultra-wideband technology. This patent answers that question and provides legal protection against infringement as we move forward with product shipments and customer design-in activities. In addition, this reinforces XtremeSpectrum's position as the leader in the development of commercial ultra-wideband product." About Patent Number 6,505,032 Patent 6,505,032 relates to the way that a wireless signal, using ultra-wideband wireless technology, is communicated. Termed bi-phase modulation, this approach was first developed for ultra-wideband by XtremeSpectrum and implemented in the company's ultra-wideband chipset, Trinity. Trinity became the first commercial ultra-wideband product for multimedia applications when it was announced in June 2002 and is currently the only commercial ultra-wideband product for multimedia applications available. Specifically, patent number 6,505,032 covers voice, data or video signals transmitted using bi-phase modulated ultra-wideband. The patent covers a method of encoding the application data into wavelets See wavelet compression. Wavelets The elementary building blocks in a mathematical tool for analyzing functions. The functions can be very diverse; examples are solutions of a differential equation, and one- and two-dimensional signals. , transmitting a carrierless ultra-wideband waveform via an antenna that includes the wavelets, receiving the carrierless ultra-wideband waveform with an antenna, and decoding the application data from the wavelets. XtremeSpectrum was first to recognize that bi-phase modulated UWB (Ultra-WideBand) A wireless technology that uses less power and provides higher speed than 802.11 Wi-Fi networks or first-generation Bluetooth products. UWB is expected to provide wireless video transmission for home theater systems, cable TV, auto safety and systems would always deliver at least twice the data rate of alternative UWB modulation techniques. This includes the Pulse Position Modulation pulse position modulation: see modulation. (PPM), On-Off Keying On-off keying (OOK) is a type of modulation that represents digital data as the presence or absence of a carrier wave. In its simplest form, the presence of a carrier for a specific duration represents a binary one, while its absence for the same duration represents a (OOK) and Pulse Amplitude Modulation amplitude modulation: see modulation; radio. Varying the voltage of a carrier or a direct current in order to transmit analog or digital data. Amplitude modulation (AM) is the oldest method of transmitting human voice electronically. (PAM) employed elsewhere in the industry. The advantage of bi-phase modulation is a direct result of its superior utilization of the transmitted signal power. This makes the bi-phase ultra-wideband approach superior for high data rate, portable applications such as adding wireless capability to displays (PDP (1) (Plasma Display Panel) See plasma display. (2) (Policy Decision Point) See COPS and XACML. (3) (Programmed Data P , LCD and DLP (Digital Light Processing) A data projection technology from TI that produces clear, readable images on screens in lit rooms. DLP is used in all types of projection devices, from data projectors that weigh only a few pounds to large rear-projection TVs to electronic ) camcorders, digital cameras, and other multimedia capable consumer products. Bi-phase offers several advantages over mono-phase techniques, the most significant of which is a 2x improvement in overall power efficiency. In other words Adv. 1. in other words - otherwise stated; "in other words, we are broke" put differently , bi-phase will always deliver twice the data rate as a function of distance compared to any of the mono-phase systems. This makes the bi-phase ultra-wideband approach superior for high data rate, portable applications such as adding wireless capability to displays (PDP, LCD and DLP) camcorders, digital cameras, and other multimedia capable consumer products. About Ultra-wideband Technology Ultra-wideband is a wireless technology that transmits an extremely low power signal over a wide swath of radio spectrum. Unlike conventional radio systems that operate within a relatively narrow bandwidth, i.e. Bluetooth, IEEE (Institute of Electrical and Electronics Engineers, New York, www.ieee.org) A membership organization that includes engineers, scientists and students in electronics and allied fields. 802.11b, IEEE 802.11a, ultra-wideband operates across a wide range of frequency spectrum by transmitting a series of very narrow and low power pulses. The combination of broader spectrum, lower power and pulsed data means that ultra-wideband causes less interference than conventional narrowband radio solutions, and delivers wire-like performance in an indoor wireless environment. This makes ultra-wideband technology ideal for consumer electronics applications that are increasingly multimedia-rich in content. About XtremeSpectrum Founded in 1998, XtremeSpectrum Inc. is the leading provider of ultra-wideband solutions for the multimedia connectivity industry. Leveraging its patented bi-phase modulation approach, XtremeSpectrum's ultra-wideband digital radios allow multimedia-centric devices, such as displays, set-top boxes, laptops, DVDs, video recorders and digital cameras, to send and receive multiple streams of digital video, audio and data wirelessly, all at extremely low price points and power consumption levels--levels that cannot be reached by existing solutions.
