The voice call was made to an off-the-shelf Qualcomm CDMA PCS handset and was processed on the company's SpectruCell SDR multiple protocol wireless base station. Perhaps most importantly, the call was made without the use of any protocol specific hardware or Qualcomm chipsets.

This successful demonstration complements the company's recently demonstrated support for a CDMA data call on a SDR platform and expands the SpectruCell wireless base station's CDMA capabilities to full two-way support for voice. Importantly in completing the voice call ACT has demonstrated the ability to combine the voice codec and CDMA chip rate processing into the SpectruCell multiple protocol wireless base station. 

Generally, this voice coding is not done at the base station but is conventionally conducted in separate transcoder units. Accordingly, this demonstration is a strong validation that with SpectruCell functionality, it is now technically possible to build more distributed networks through using software radio technology. The demonstration also convincingly confirms that software radio is able to handle CDMA chip rate processing and voice coding simultaneously on the same compact platform.

``ACT's list of world's first technical achievements continues to expand at a very rapid rate'', said Roger May, CEO of ACT-USA. ``These demonstrations prove that we have a viable and definitive solution for mobile carriers looking to implement CDMA and evolving 3G protocols in a SDR environment. Going forward, industry indications suggest that this will clearly be the preferred way to implement the CDMA protocol. 

Given that the system is software based, parameters such as the search space and user density can be easily updated in the field which gives the network operator tremendous flexibility. Existing hardware based implementations of CDMA do not provide an ability to allow for these changes without significant cost because of the potential for substantial network downtime due to the necessity for extensive hardware replacement upgrades to achieve such changes. 

Apart from the inherent flexibility SDR base stations will afford the mobile network operator, the fact that the SpectruCell SDR multiple protocol base station can provide this support without any Qualcomm CDMA chipsets provides significant potential to generate very substantial savings in licensing fees typically due to Qualcomm when rolling out CDMA networks''.

Designed from the outset as a device capable of simultaneously supporting multiple communications protocols, ACT's SpectruCell SDR base station will offer a myriad of cost savings and operational advantages for network operators. 

Perhaps most significantly, such advantages would include the ability to provide virtual or shared network support. Under this shared network configuration multiple carriers can share the one network infrastructure with the SpectruCell operating system handling multiple protocols and even different bands of spectrum all within the same base station/network infrastructure.

May added, ``The potential savings expected to be generated by SpectruCell's virtual/shared network capabilities are immense. By multiple carriers co-locating on the one SpectruCell network, individual carriers can eliminate costly duplication of network infrastructure thereby ensuring that each mobile network operators can still provide a distinctly unique SDR service with shared cell sites and infrastructure at a much lower establishment cost''.

Video of World First Demonstration of CDMA Support on an SDR Platform

A video clip of the company's latest achievement of two way CDMA voice support is available at http://www.act-aus.net/scdemo this video has been broken into four segments to aid downloading.

ACT's original demonstration of the establishment of a CDMA data call to a handset from the SpectruCell SDR base station can be viewed in a video clip located at http://www.act-aus.net/video/scdemo.html (the video requires Quicktime 5, a download link for the program is provided on ACT'S website).

ACT has lodged numerous patent applications to protect its SpectruCell technology and has recently filed formal blocking patent applications covering the core operating system process for implementing CDMA on a SDR platform under the Patent Cooperation Treaty which provides patent protection in 89 member countries.

``Given the rapidly evolving recognition of the many advantages of SDR technology and the increasing support SDR is gaining from industry regulators like the FCC, it is becoming increasingly evident that the company is extremely well positioned to capitalize on the substantial asset of the protected Intellectual Property that is capable of generating significant income. This should place us in a ''Qualcomm like model`` powerful competitive position as other communications equipment and base station manufacturers seek to expand the integration of software defined radio technology into their product lines'', said May.

About Advanced Communications Technologies

Advanced Communications Technologies Inc. (ACT) is a world leader in the development of software-defined radio (SDR), an innovative technology that allows for exceptional flexibility in commercial and military wireless communications. The Company's flagship product - SpectruCell, is a SDR multiple protocol wireless base station consisting of hardware and software, that enables network providers to install a single base station and configure it to any or all protocols (GSM, CDMA, UMTS, W-CDMA, etc). Without SpectruCell, network providers would need to install separate base stations for each desired protocol. SpectruCell is supported by several patent filings that bypass the large majority of Qualcomm's patents on CDMA via hardware solutions.
