Popular P25 Public Safety Waveform Ported to Spectrum's Software Reconfigurable Radio

BURNABY, BRITISH COLUMBIA, May 27 (MARKET WIRE) --
Spectrum Signal Processing by Vecima (TSX: VCM) ("Spectrum"), an advanced
communications equipment supplier, announced today a partnership with
Communications Research Centre Canada (CRC) to port the Association of
Public-Safety Communications Officials (APCO) Project 25 (P25) public
safety waveform to Spectrum's flexComm(TM) SDR-4000 software
reconfigurable radio. P25 is the latest addition to Spectrum's expanding
waveform portfolio. This waveform is the most popular and widely used
public safety waveform in North America. Supporting this waveform on a
software reconfigurable radio allows military and other users to more
easily communicate with public safety personnel to better co-ordinate
joint emergency efforts. A demonstration of this implementation is
provided at CANSEC 2009, in Ottawa, and features an industry standard P25
radio talking over-the-air to an SDR-4000.

"Spectrum continues to expand its waveform portfolio, offering its
customers more options and applications available with its software
reconfigurable technologies," said Mark Briggs, VP Marketing at Spectrum.
"We are pleased to continue working closely with CRC to provide our
markets with software defined implementations of waveforms critical to
both military and civil user communities."

"CRC selected the SDR-4000 because it provided the comprehensive
hardware, software, and environment required for the P25 port," said
Claude Belisle, VP Satellite Communications and Radio Propagation branch
of CRC. "The SDR-4000 also supported the entire Software Communications
Architecture (SCA) software operating stack that was critical in making
this project successful."

The SDR-4000 has been proven to support implementations of military
waveforms, such as the Joint Tactical Radio System (JTRS) Wideband
Networking Waveform Orthogonal Frequency Division Multiplexing (WNW
OFDM), Soldier Radio Waveform Electronic Warfare (SRW EW), and Single
Channel Ground and Airborne Radio System (SINCGARS). Adding a public
safety waveform such as P25 lays the foundation for interoperability
between military and civil agencies.

About the SDR-4000

The SDR-4000 is a multi-purpose software reconfigurable transceiver that
combines heterogeneous processing including digital signal processors
(DSP), general purpose processors (GPP) and field programmable gate
arrays (FPGA). The SDR-4000 is packaged in a small 3U CompactPCI(R)
form-factor and is available in air-cooled for benign environments or
conduction-cooled packages for deployments in harsh environments. The
SDR-4000 is available with a real-time operating system, hardware
abstraction layer, and CRC's SCARI Software Suite, a complete development
environment for the SCA. For more information on the SDR-4000, please

About the P25 Implementation

P25 is a suite of system standards that define digital radio
communications system architectures addressing the needs of public safety
and government organizations. P25 involves digital land mobile radio
services for local, state/provincial and national public safety
organizations and agencies.

The implementation includes the Phase I Common Air Interface (CAI) in
Conventional mode at 9.6 kbps. This air interface works with 12.5 kHz
channels, allowing the transmission of data or coded voice with the
Continuous 4 level FM (C4FM) modulation format. The MAC sublayer performs
encapsulation and imbeds frame synchronization information, according to
the CAI specification. The Logical Link Control (LLC) sublayer includes
both voice and data packets processing, along with their respective
interleaving and error correction schemes as specified in the CAI. The
implementation is fully compatible with, and has been fully tested under,
the SCA framework.

Spectrum and CRC will be demonstrating P25 running on the SDR-4000 during
the CANSEC tradeshow happening May 27-28, 2009 in Ottawa, ON. Please

sales@spectrumsignal.com to find out more.
