(TSX:SSY)(NASDAQ:SSPI) today announced at MILCOM 2006 the availability of its flexComm™ SDR-4000 Tactical Military Communications (MILCOM) Rapid Deployment Platform (TMRDP). This platform equips quick response teams with an integrated platform designed for the rapid development and deployment of tactical MILCOM applications. The commercial-off-the-shelf SDR-4000 TMRDP provides full "RF to Ethernet" functionality of a software defined radio (SDR) with support for the Software Communications Architecture (SCA) in a single 19" rack. It integrates Spectrum's high performance SDR-4000 wireless modem, a DRT4001 RF front-end by Digital Receiver Technology, Inc. (DRT), a GPS receiver and all the software necessary for tactical MILCOM deployments.

"The SDR-4000 TMRDP is the latest in our family of integrated platforms targeted for military radio developers that require "RF to Ethernet" functionality in a single subsystem and want a fast path to deployment," said Mark Briggs, Vice President, Marketing at Spectrum Signal Processing. "Customers can use this off-the-shelf platform to develop and deploy their complex tactical MILCOM applications, allowing their in-house resources to focus on deployment-critical functionality."

The SDR-4000 TMRDP is ideally suited for tactical MILCOM applications including ground vehicular, airborne and shipborne systems, tactical data links, beamforming and multiple input/multiple output (MIMO) systems, as well as verification and validation.

The SDR-4000 TMRDP includes the following functionality:

- Spectrum quicComm™ hardware abstraction layer

- A real-time operating system with an integrated development environment

- A CORBA Object Request Broker (ORB)

- An SCA Core Framework

- An RF control application program interface (API) to manage all functionality of the RF subsystem

- A comprehensive set of processor-to-processor data flows and a system data flow example with digital down-converter (DDC) and digital up-converter (DUC). The system software example provides receive coverage from the RF input, through the signal processing chain and transmit coverage from signal processing to RF output. All data flow software examples include source code.
