ArrayComm introduces high capacity IntelliCell WLL system; patented technology improves signal quality, spectral efficiency and base station range.

SAN JOSE, Calif.--(BUSINESS WIRE)--June 5, 1996--ArrayComm Inc., a Silicon Valley-based telecommunications firm, announced the availability of its IntelliCell wireless local loop (WLL) system, based upon the company's revolutionary adaptive wireless communications technology.

The system is comprised of a base station embedded with the IntelliCell processor, a low cost subscriber unit, a flexible, E1- or T1-based network interface and a comprehensive element manager. The IntelliCell processor combines signals from multiple antennas to produce dramatic increases in signal quality, spectral efficiency and base station coverage.

The system combines the benefits of IntelliCell processing and the proven 32 Kbps adaptive differential pulse code modulation (ADPCM) technology to deliver wireline voice quality. The IntelliCell base station, whose bandwidth is scaleable in 300 KHz increments, operates in the 1900 MHz frequency band and can serve more than 2,000 high-usage WLL subscribers per 10 MHz of spectrum.

"Operators in developing countries are embracing wireless local loop systems to expeditiously address the tremendous demand for telecommunications," stated Martin Cooper, chairman and CEO of ArrayComm. "ArrayComm's WLL system will help them meet this demand in a highly cost-effective manner, particularly where spectrum is already limited."

The company's breakthrough Spatial Channel feature, introduced for the first time in the IntelliCell WLL system, enables same-cell frequency reuse in order to achieve its high spectral efficiency and low cost per subscriber. The IntelliCell base station and subscriber units have flexible, programmable architectures, enabling many system upgrades and enhancements to be implemented in software only.

The number of antennas, radios and voice channels in the base station can be scaled independently, enabling an operator to grow with the needs of its evolving subscriber base. Because the IntelliCell system is self-optimizing and features dynamic channel allocation, radio and site planning are minimized.

Worldwide telephone penetration is currently at 11%, and less than 5% in many developing countries. At the same time, the global infrastructure is growing at 40% per year. Cooper believes that the WLL will account for more than half of this growth by the year 2000.

"ArrayComm is uniquely positioned with its adaptive WLL system to take advantage of this expected growth," Cooper pointed out. "We are developing strategic relationships with local manufacturers, distributors and operators throughout the world in order to meet the unique need of specific WLL markets." Trials of the IntelliCell WLL system are planned during the course of this year.

ArrayComm is the leading global source of adaptive wireless communications solutions. The company's revolutionary IntelliCell processor is at the heart of ArrayComm's wireless access solutions. IntelliCell technology, which is compatible with all of the world's leading wireless standards, combines ArrayComm's innovative digital signal processing platform with multiple antennas to enhance base station performance and system economics.

This unique approach to wireless access enables cellular, PCS and wireless local loop networks to realize unparalleled increases in signal quality, capacity and coverage, by automatically adapting to the complexities of the RF environment and continuously enhancing users' signals in real time. From the IntelliCell processor to innovative wireless local loop systems, ArrayComm is helping to make high-quality wireless communications truly affordable for mass markets worldwide.
