ArrayComm Inc. announced it received a U.S. patent for its Spatial Division Multiple Access intelligent antenna technology-the brains behind the company’s IntelliCell products. The company also announced its IntelliCell Wireless Local Loop system is commercially available.
IntelliCell uses spatial and temporal parameters to decipher antenna signals. Installed in a base station, the IntelliCell software and hardware platform uses multiple antennas and digital signal processing to yield improved performance and reduce equipment and buildout costs for 1900 MHz wireless networks, said the company. Systems equipped with SDMA can extend base station range, increase system capacity, improve signal quality and create greater network flexibility, according to ArrayComm.
The IntelliCell WLL system is comprised of a processor that is embedded in a base station, a low cost subscriber unit, a flexible E1- or T1-based network interface and a comprehensive element manager. IntelliCell’s Spatial Channel feature enables same cell frequency reuse.
Also, IntelliCell’s processing and 32 kilobit-per-second adaptive differential pulse code modulation (ADPCM) technology brings wireline voice quality to wireless networks, ArrayComm said.
The first generation of SDMA was invented in the 1980s by Richard Roy III, ArrayComm’s chief technical officer, and Bjorn Ottersten, director of research and development, said Marty Cooper, the company’s chairman and chief executive officer.
In related news, ArrayComm announced it will implement an IntelliCell WLL in India, based on the Personal HandyPhone System standard, through a consortia including National Radio and Electronics Co. Ltd. (NELCO) and Nichimen Corp./Nichimen America Inc. NELCO is providing equipment and Nichimen is providing financial support in the project.
