Advanced Communications Technologies -- SpectruCell 3G Multiple Protocol SDR Base Station/Switch Update and Commercial Release.

Business Editors and High-Tech Writers

LOS ANGELES--(BUSINESS WIRE)--July 11, 2001

Advanced Communications Technologies Inc (OTCBB:ADVC) (ACT-US) today announced that the company is on track to deliver its SpectruCell software defined radio mobile wireless base station in first quarter of 2002 and that the company expected to generate initial revenues from the SpectruCell technology in late 2001.

The company's development efforts have recently received a major boost from the formation of an alliance between its Australian based research and development operations and RLM Systems Pty Ltd (RLM), a joint venture subsidiary company jointly owned by Lockheed Martin (NYSE:LMT) and Tenix Australia Pty Ltd.

RLM's high level skill set and experience in building out complex projects provides the ideal complement to ACT's world leading innovation in software defined radio and communications technologies. This powerful combination of leading edge technical resources is expected to provide the company with a significant reduction of the SpectruCell project lead times and is expected to ensure that ACT has the first third generation (3G) ready software defined mobile wireless base station in the market at the end of the first quarter of 2002.

In addition to its commercial applications, ACT is also negotiating initial development of military applications for SpectruCell. This augurs exceptionally well for the company's U.S. operations where military spending on communications in calendar year 2000 alone was in excess of $US16 billion.

ACT is also making significant in-roads towards initial sales of the SpectruCell technology with the upcoming release of the company's software defined radio development tools and development suite. Designed to allow third parties to develop applications for the SpectruCell software defined radio platform, the suite is receiving substantial interest from communications developers of 3G applications who are keen to obtain access to a highly flexible 3G application development platform that is capable of being easily modified via software upgrades to the comply with any evolving predominant 3G protocol. Such flexibility is not currently available in presently available hardware specific 3G development platforms. The first of the 3G development platform technologies within this suite, an analogue to digital converter board, will be available to developers from early August 2001.

The company is also pursuing orders for the SpectruCell base station unit from major U.S. and UK/European based carriers. Negotiations to date have centered around two major network providers in the U.S. mobile market with the company now looking to firm up an order for delivery in early 2002.

SpectruCell -- Virtual /Shared Network Facilities

Perhaps most importantly, SpectruCell's architecture allows it to act as a Virtual Network Operator (VNO). This feature is particularly relevant as many network operators around the world are now looking to share network infrastructure in order to reduce the network roll out costs associated with supporting 3G services. The use of SpectruCell's VNO capabilities essentially means that a network operator can provide network support for other carriers on the one network infrastructure regardless of whether those providers are using different protocols or spectrum. This provides an exceptional level of network functionality and generates significant time and cost savings.

The exceptional flexibility of the SpectruCell base station has generated significant interest from carriers who are looking for solutions to help them deal with difficulties arising from both spectrum shortages and the myriad of communications standards that prevail in the U.S. and U.K. mobile communications market.

Protection of the company's significant intellectual property is naturally paramount and to this end the company is ensuring that its research and development operations file a steady stream of patent applications. To date these filings have centered around innovative technologies ranging from methods for implementing communications protocols (GSM, CDMA, etc) on a software defined radio platform to the core design of a software radio platform itself. A key patent filing has recently been delayed due to the complexity of the claim, however the company expects to make additional filings in the next seven days. Full details will be announced upon lodgment of the respective claims.

About Advanced Communications Technologies

Advanced Communications Technologies, in conjunction with its Australian based affiliate ACT (Australia) Pty Ltd, is a leader in the field of Software Defined Radio and has developed a proprietary, multiple-protocol wireless base station -- SpectruCell. Through eliminating the use of Qualcomm (Nasdaq:QCOM) chipsets and protocol specific hardware, and by conducting all signal processing in software, SpectruCell provides for simultaneous support of multiple mobile communications protocols (CDMA, WCDMA, UMTS, GSM & 3G) all in the same base station. Support for additional protocols is achieved through the uploading of additional software modules.

By implementing the company's SpectruCell technology, network providers will be able to maintain service to their existing customer base and preserve the full utilization of their existing network infrastructure while at the same time securing a highly flexible migration path for evolving 3G-based protocols such as WCDMA and UMTS. SpectruCell is complemented by several other wireless technologies currently under development in Australia. Advanced Communication Technologies plans to market these products throughout North, South and Central America.
