LOS ANGELES--(BUSINESS WIRE)--June 13, 2001

Advanced Communications Technologies Inc. (OTCBB:ADVC) (ACT-US) today announced that the organizers of the TETRA World Congress, that will take place in France in December 2001, have invited representatives of the company's Australian affiliate, ACT Australia, to present at the upcoming conference.

"The invitation followed the very successful presentation at the recent conference in Hong Kong, by Paul Staugaitis, RF team leader for ACT. The essence of the ACT presentation was a discussion of the benefits of SDR and ACT's implementation of certain aspects, over a conventional hardware specific set-up. This naturally including the highlighting of SDR's exceptional flexibility in dynamically reconfiguring networks and allowing for a seamless upgrade path to new technologies," said Roger May, CEO of ACT-US.

"In a major endorsement of the company's authority on this highly topically issue, the organizers of the Hong Kong conference have approached Mr. Staugaitis to present at the TETRA World Congress in France at their expense. We naturally view this move as further recognition and confirmation of ACT's leading role in the development of SDR technologies and of the unique opportunity that ACT has to assume a prominent leadership role in the rapidly evolving development of next generation SDR/3G communications networks. This situation augurs very well for the upcoming commercialization of the SpectruCell operating system platform."

ACT's most recent conference presentations have included presentations at the TETRA Asia-Pacific Congress 2001 in Hong Kong and the IEEE sponsored 2001 International Conference on Third Generation Wireless and Beyond. These two papers gave both a comprehensive account of the benefits of ACT's software defined radio (SDR) technology and an insight into the techniques employed by ACT engineers to achieve the high levels of communications performance exhibited by the SpectruCell software defined wireless mobile network base station.

ACT's most recent presentation was in its home market of the United States where David Lynes, the company's principal engineer, presented a paper on Cellular BTS SDR Framework. While prepared for a more technically inclined audience, the paper provide valuable insights into the world leading advances ACT has made in SDR, and especially in the unique design and implementation of its multiple protocol wireless base station.

"This paper provided a solid demonstration of ACT's technical expertise. It was designed to give attendees a feel for how we have actually gone about achieving the success we've had with SpectruCell to date such as the inclusion of an open interface with a proprietary core. It also included a discussion of the methods we've used to achieve the performance we have using existing componentry in conjunction with ACT's proprietary SDR software.

"As recently as a few years ago the capabilities of the SpectruCell base station were simply not possible due to a lack of processing power. Our research continues to push the boundaries of performance and this paper provided a clear demonstration of our leadership in this field," said May.

May added, "The company firmly believes that this latest conference invitation is a significant confirmation of an official recognition of ACT's leading position in the implementation SDR/3G solutions by the communications industry leaders globally," said May.

About Advanced Communications Technologies

Advanced Communications Technologies is a leader in the field of Software Defined Radio (SDR) that in conjunction with its Australian based affiliate has developed a proprietary, multiple-protocol wireless base station -- SpectruCell. Through eliminating the use of Qualcomm (Nasdaq:QCOM) chipsets, 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.
