Title: ParkerVision Receives Fifth Wireless Patent
Date: 7/24/2001; Publication: PR Newswire;
Further Strengthens D2D Intellectual Property Position

 

JACKSONVILLE, Fla., July 24 /PRNewswire/ –
ParkerVision, Inc. (Nasdaq: PRKR) today received its fifth U.S. patent for its unique Direct2Data(TM) wireless semiconductor technology, which is in the process of being commercialized for the wireless LAN and cellular markets.

 

U.S. Patent 6,266,518, which was issued to ParkerVision by the United States Patent & Trademark Office, contains 99 claims, including 9 independent claims, and cites over 600 references. It is part of ParkerVision’s overall intellectual property strategy, which includes 5 U.S. patents and more than 80 other patents pending in the United States and throughout the world.

 

The new patent further strengthens ParkerVision’s intellectual property claims for its unique radio frequency (RF) receiver architecture (Patent 6,601,551), which provides efficient direct down-conversion in a single step from a modulated RF carrier to baseband. The new patent focuses on features of the D2D technology that result in higher signal-to-noise (S/N) ratios across a wide range of frequencies. Such favorable S/N ratios enable the production of higher quality receivers and transceivers that are capable of satisfying a wide range of communication standards, for products such as wireless LAN cards and cellular telephones.

 

“This patent is important to us as it amplifies more of Direct2Data’s inherent advantages and further protects our unique direct conversion architecture,” stated David Sorrells, Chief Technical Officer. “A key focal point of ParkerVision’s latest patent is to demonstrate how energy sampling and matched filter theory can simultaneously coexist to facilitate higher levels of system integration in demanding standards based applications such as cell phones and wireless LAN devices. This patent disclosure represents the next step in explaining why Direct2Data is a superior radio frequency transceiver platform and does not suffer from the shortcomings of traditional direct conversion approaches.”

 

ParkerVision, headquartered in Jacksonville, Florida, designs, develops and manufactures communications technology platforms and products for the wireless and video industries. The video division is engaged in the design, development and marketing of automated video camera control systems and automated live production systems for broadcasting and webcasting.

 

ParkerVision is a leader in direct conversion radio technology. Its patented D2D(TM) radio communications technology enables the development of advanced, highly integrated products for a wide range of wireless and wired radio-based devices. D2D’s innovative RF technology simplifies wireless electronics, resulting in smaller, cost-effective, high-performance wireless communications products.
