Tuesday, August 30, 2011

OFDMA inventions improve user experience in 4G wireless systems

Carrollton, TX -- ADAPTIX Inc., a pioneer in the development of orthogonal frequency division multiple access (OFDMA) technology, announced today that it has been awarded two new U.S. patents relevant to 4G and other wireless technologies.

U.S. Patent 8,005,479, entitled “Method and Apparatus for Adaptive Carrier Allocation and Power Control in Multi-Carrier Communication Systems,” was issued on Aug. 23, 2011, and describes methods for wireless frequency carrier allocation in conjunction with dynamic power control. Power control in wireless systems is an important feature for minimizing interference between subscribers while maximizing handset battery life, thereby greatly improving the overall user experience.

U.S. Patent 8,010,118, entitled “Systems and Methods for Making Channel Assignments to Reduce Interference and Increase Capacity of Wireless Networks,” is being issued today, and details methods in which wireless systems may optimize available bandwidth for use by multiple subscribers using their connected devices.

“ADAPTIX is very pleased to have been awarded these two new patents,” said Byron Young, vice president of marketing and technology. “The concepts and methods covered by these patents provide an excellent basis for how 4G wireless networks may more effectively manage frequency allocation and power control in real-world conditions. The net result is a more robust and faster user experience.”


ADAPTIX, Inc. is an award-winning technology company long recognized in the industry as one of the first developers of cutting edge OFDMA-based mobile wireless systems.
