Iospan Wireless Expands Intellectual Property Portfolio for Multiple Antenna Technology.Business Editors/High-Tech Writers SAN JOSE, Calif.--(BUSINESS WIRE)--Jan. 28, 2002 Iospan Wireless, Inc., the leader in wireless broadband multiple antenna technology, today announced that it has been issued a patent 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 (USPTO USPTO abbr. United States Patent and Trademark Office ) for optimizing the use of multiple antennas in a wireless system. This brings Iospan's total number of patent claims to over 1600, with over 40 patents issued, pending and licensed, and solidifies Iospan's leadership role in developing, delivering and enabling innovative wireless communications products and services employing Multiple Input, Multiple Output (MIMO (Multiple Input/Multiple Output) Pronounced "my-mo," it is the use of multiple transmitters and receivers (multiple antennas) on wireless devices for improved performance. ) technology. "As the pioneer of MIMO technology, Iospan Wireless has put a great amount of emphasis on our technology development program," stated Levent Gun, Iospan Wireless' president and 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. . "Iospan's extensive intellectual property holdings are a tribute to our accomplishments and highlight the wide applicability of our AirBurst air·burst n. Explosion of a bomb or shell in the atmosphere. Noun 1. airburst - an explosion in the atmosphere blowup, detonation, explosion - a violent release of energy caused by a chemical or nuclear reaction (TM) technology to virtually any type of wireless system -- wireless LANs, portable wireless, and mobile wireless." Iospan Wireless' latest patent win focuses on the company's ability to provide broadband wireless systems with a method of controlling communication parameters in a wireless channel utilizing multiple antennas. More specifically, this patent covers the performance optimization of multiple transmit antennas. Iospan's MIMO-OFDM MIMO-OFDM Multiple In, Multiple Out-Orthogonal Frequency Division Multiplex multiple antenna technology dramatically improves system spectral efficiency, which extends coverage, increases capacity and enhances Quality of Service (QoS) in wireless systems. This method can be employed in virtually any type of wireless communications system, using multiple access techniques including OFDM (Orthogonal Frequency Division Multiplexing) A digital transmission technique that uses a large number of carriers spaced apart at slightly different frequencies. , TDMA (Time Division Multiple Access) A satellite and cellular phone technology that interleaves multiple digital signals onto a single high-speed channel. For cellular, TDMA triples the capacity of the original analog method (FDMA). , CDMA (Code Division Multiple Access) A method for transmitting simultaneous signals over a shared portion of the spectrum. The foremost application of CDMA is the digital cellular phone technology from QUALCOMM that operates in the 800 MHz band and 1.9 GHz PCS band. , FDMA (Frequency Division Multiple Access) The technology used in the analog cellular telephone network that divides the spectrum into 30 kHz channels. See TDMA, CDMA and CDPD. FDMA - frequency division multiple access , TDD, and FDD. Earlier this month Iospan Wireless announced successful field trials of the world's first MIMO-OFDM Non-Line-of-Sight (Non-LOS) fixed broadband wireless system. These trials demonstrate the ability of MIMO-OFDM-enabled AirBurst technology to enable the deployment of next-generation broadband wireless services. AirBurst technology is designed to allow service providers to quickly deploy broadband wireless services for both residential and business applications that will successfully compete with existing broadband technologies on cost, coverage, and capacity. Iospan Wireless is partnering with leading solutions vendors to enable service providers with Non-LOS, mass-deployable broadband wireless access solutions. Iospan Wireless offers AirBurst(TM) chipsets, reference designs and board-level solutions to wireless OEMs interested in creating broadband wireless systems designed for the residential and business markets. Iospan's AirBurst is the only technology that currently meets all of the IEEE 802.16.3 channel models for fixed wireless applications. Iospan Wireless is continuing field trials of its MIMO-enabled AirBurst technology through early 2002, demonstrating the benefits of its technology to broadband wireless systems integrators, equipment manufacturers and wireless service providers. Note to Editors and Analysts: Members of the press and analyst community interested in learning more about MIMO-OFDM are invited to contact the company to arrange an in-person demonstration of Iospan's technology live from the site of their Bay Area field trials.
