About Advanced Communications Technologies

Advanced Communications Technologies Inc. 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, or any other 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 Inc. plans to market these products throughout North, South and Central America.
