SuperCapacity AdaptaCell Base Station Is Revolutionary and Unparalleled in Performance

Melbourne, FL, August 20, 2002 - AirNet Communications Corporation (NASDAQ: ANCC), the technology leader in software defined base station products for wireless communications, today announced that it has successfully demonstrated its SuperCapacity AdaptaCell® base station utilizing ArrayComm, Inc.'s IntelliCell® adaptive array technology. More than ten potential customers and wireless experts from around the world attended this landmark field trial at AirNet.

Invited operators and experts participated in a progressive sequence of field tests that have confirmed the significant cost, capacity and performance benefits of the SuperCapacity AdaptaCell base station. Simultaneous adaptive and non-adaptive wireless calls under identical conditions were made repeatedly in the presence of interfering signals. In all cases, the adaptive calls significantly outperformed the non-adaptive calls. During testing, the SuperCapacity AdaptaCell base station yielded improved interference mitigation of up to 30 dB on the uplink and up to 22 dB on the downlink. Based on these tests, an operator could expect to see real world interference mitigation improvement that is up to 1,000 times better than interference mitigation on their GSM and high speed data networks.

“This technology is revolutionary and will significantly improve capacity, call quality and data rates for many operators who are congested and at the physical limits for performance in their networks,” said Glenn Ehley, president and CEO of AirNet. “In addition, this technology is far more cost-effective than any other solution previously adopted because it reduces by up to six times the number of cell sites needed for high speed data applications. We have now successfully demonstrated to the world a solution that many thought could not be accomplished.”

“ArrayComm is delighted to have participated in this historic occasion,” said Sam Endy, chief operating officer of ArrayComm. “With the delay in 3G network deployments, demand for increased capacity, coverage, and performance will continue to increase. We believe the SuperCapacity Base Station, with its broadband Software Defined Radio architecture and incorporating ArrayComm’s IntelliCell adaptive array technology, is a compelling and cost-effective solution for GSM networks – the largest cellular market in the world.”

One of the primary benefits of the SuperCapacity base station is that AirNet's solution provides high-speed data over the entire existing cell area. Competitors' solutions only provide high-speed data in part of the existing cell, requiring operators to install up to six times as many cell sites to cover the same area to achieve service uniformity. In addition, the improved throughput of the new SuperCapacity base station enables it to handle dramatically more traffic through any given cell, maximizing the use of the operator's radio spectrum. This capacity improvement will enable operators to significantly increase the number of users within their coverage area, and provide additional high-speed services - without adding new base stations or towers.

“The combination of our broadband, SDR architecture and the adaptive antenna array technology dramatically increases the network’s spectral efficiency - resulting in tremendous increases in system performance. In order to support capacity demands on traditional wireless systems, operators run into significant levels of interference between cells, which results in service degradation such as dropped calls. Our solution rejects interference, and the radio performance translates into higher service quality in the network,” commented Thomas R. Schmutz, vice president of Engineering for AirNet.

Mr. Schmutz went on to comment that operators will be able to improve the quality of the voice and the speed and range of data communications on their networks. Traditional systems are prone to interference because they have to transmit signals over a wide area to locate the end user. Their dispersed approach means most of the signal power is wasted. In contrast, adaptive array technology reduces interference, improves voice quality, and conserves signal power by focusing and receiving energy only in desired locations. AirNet’s broadband, SDR platform is the only cost-effective architecture to allow this technology breakthrough for 2G, 2.5G and 3G deployments.
