ADAPTIX, a pioneer in the development of orthogonal frequency division multiple access (OFDMA) technology, has been granted eight new patents by the governing patent agencies in Japan, Australia, Hong Kong and South Korea. Already possessing an increasingly impressive intellectual property (IP) portfolio focused on OFDMA and related next-generation wireless technology patents in the United States, ADAPTIX continues to build on its global patent portfolio with these new patents.
"We have clearly demonstrated the strength of our wireless broadband-focused intellectual property rights portfolio in the United States," said Byron Young, ADAPTIX Vice President of Marketing and Product Management. "With these newly granted international patents, we expand further on a global IP portfolio that already includes patents granted in mainland China, Mexico and other jurisdictions. The growing ADAPTIX IP portfolio clearly reflects our early involvement in OFDMA development and our independence from third parties for our core technologies."
The Japanese, Australian and Hong Kong patents (2002-535271, 2002211628, 4105278.8) describe, among other features, a Medium Access Control (MAC) layer controlling OFDMA-based cellular networks. The Korean patents (2003-7005079, 2003-7007961, 2003-7007963, 2003-7007962, 2006-7020261) describe, among other features, both MAC over OFDMA and assignment of subcarriers and subcarrier groups (or "clusters") in OFDMA systems.
These inventions, which already have been integrated into ADAPTIX's products, describe important capabilities for both mobile and fixed 4G wireless systems based on OFDMA. Such systems may include, but are not limited to, Mobile WiMAX (IEEE 802.16e), 3GPP's Long Term Evolution (LTE), Next Generation Personal Handyphone System (NG-PHS) and 3GPP2's Ultra-Mobile Broadband (UMB). The patents also demonstrate ADAPTIX's advanced internal technical capabilities and long history of developing leading-edge solutions based on OFDMA and related broadband access technologies.
