ArrayComm Announces New Features for Its Intelliwave WLL System; Greater Flexibility and Price Competitiveness for Wireless System Operators.

SINGAPORE--(BUSINESS WIRE)--June 2, 1998--ArrayComm, a U.S.-based manufacturer of leading-edge wireless telecommunications products, has expanded the capabilities of its IntelliWave(TM) wireless local loop (WLL) system.

The recent system enhancements further enable wireless operators to expand new markets in less time, with greater flexibility, and with lower installation and maintenance costs.

ArrayComm will exhibit a live IntelliWave system at the CommunicAsia'98 show in Singapore from June 2-5 (Booth No. 6L4-01).

"Our IntelliWave system has earned high marks in numerous installations worldwide for its performance, high capacity and reliability, and all at very low cost," stated Karl Martersteck, president and chief executive officer of ArrayComm. "The latest system advancements make it even easier for wireless operators to address the unique, changing needs of each market they serve."

Based on ArrayComm's adaptive digital signal processing technology, the innovative IntelliWave system offers high-capacity, high-quality access to the public network at a fraction of the cost of today's wireless and wireline technologies. It is powered by the IntelliCell(R) processor, which intelligently combines signals from antenna arrays to provide dramatic increases in signal quality, spectral efficiency and coverage over local loop systems based on conventional wireless access technologies.

The recent system enhancements include:

Choice of Single-line or 4-line Subscriber Units

While the Single-line SU serves an individual residence/business, the Four-line SU provides four separate subscriber line connections, each with its own phone number. Each subscriber line supports up to five devices (telephones, fax machines, etc.). Both units now feature 64 kbps data capability, high voice quality (32 kbps ADPCM, G.721), choice of indoor antenna or optional high-gain antennas and battery backup (optional).

Payphone Interoperability

Due to the flexibility of ArrayComm's system architecture, a new software enhancement enables ArrayComm Subscriber Units to perform wireless payphone service (at purchaser's request).

Added Choices in Base Station Software

Already established as a high-capacity service leader, ArrayComm now offers three new software releases to address changing operator needs for small, medium and large cell sizes. Newly released scalable configurations accommodate 30-, 60-, 120- and 155-channel configurations. This enhancement enables operators to optimally configure for excellent service and best price performance at various subscriber loading levels.

Expanded Operations Management System Capabilities

ArrayComm offers a remote operations, maintenance and control (OM&C) capability through its comprehensive IntelliWave Management System (IMS). Its scaleable architecture and standard SNMP-based user interface put all pertinent maintenance, operating and configuration information at the operator's fingertips. Designed to avoid surprises and downtime, the system can instantly remedy problems and forewarn of potential trouble before failure occurs. Control over a network of base stations is provided through two components:

Site Controller -- Featuring a full suite of configuration, alarm and performance-measurement capabilities, the IntelliWave Site Controller has an interface layer that allows easy integration with other existing management systems. Because it uses simple network manager protocol (SNMP), the managed information is also accessible to full-scale network management systems.

Craft Interface -- Typically run on a laptop computer, the Craft Interface provides an easy, task-oriented user interface for maintaining the Base Station parameters and the subscriber database. For complete flexibility, the Craft Interface can connect directly to the Base Station or to the Network Interface Unit (NIU). Used to manage the WLL system resources, the Craft Interface features easy operation, conspicuous alarm notification, and user-friendly displays.

Software Provisioning from the OMC gives operators the ability to modify subscriber information, such as adding and dropping subscribers or changing phone numbers, all with a high level of security.

Over-the-Air Software Download dramatically reduces system costs by avoiding the need for a site visit in the event of an upgrade.

"With the IntelliWave WLL system, subscriber distribution is not an issue," stated Peter Carson, ArrayComm's vice president of Business Development. "As is typical for the markets it serves, the system accommodates constant change in the subscriber base, but without the extensive frequency management and engineering headaches associated with traditional sectorized systems. And the latest remote maintenance features are a perfect complement to the system's dynamic channel allocation capabilities."

ArrayComm is the global leader in smart antenna-based wireless communications solutions. Its revolutionary IntelliCell(R) processing platform combines an innovative digital signal processing system with antenna arrays to dramatically enhance wireless system performance and economics for operators of PCS, cellular and wireless local loop networks. The technology greatly enhances voice quality and minimizes interference, and can simultaneously support multiple users on the same radio channel with adaptive, "virtual wire" connections. IntelliCell technology, on which ArrayComm has extensive patent coverage, is compatible with all wireless standards and forms the basis of the IntelliWave(TM) wireless local loop (WLL) system.

With headquarters in San Jose, Calif., ArrayComm has offices in Japan, India, France and Argentina. The company's IntelliCell-PHS technology is now in commercial use in DDI Pocket Telephone's network, which serves over 4 million customers in Japan. In addition, the company's systems have been deployed in Malaysia, the Philippines and Brazil. From the IntelliCell processor to innovative wireless local loop systems, ArrayComm is helping make high-quality wireless communications truly affordable for mass markets worldwide.
