This highly anticipated reference implementation for SCA v2.2 is scheduled for completion by November 2004 and will be certified by the Joint Tactical Radio System (JTRS) Joint Program Office (JPO). In addition, a one-channel push-to-talk application will be available to help promote increased proficiency for designers/developers working with the reference implementation, and also to demonstrate the functionality of the SCA.
"A JTRS-compliant reference implementation is important because it allows radio developers to work from a blueprint that already passes DoD muster," said Allan Margulies, Chief Operating Officer, SDR Forum. "Another benefit is that the reference implementation is written in Java, which provides an alternative implementation to the other languages in which the SCA is being developed."
The SDR Forum-CRC reference implementation will provide the wireless industry with a common interpretation of version 2.2 of the SCA, which will help ensure radio interoperability between manufacturers. Once the reference implementation is developed -- complete with JTRS certification and push-to-talk application -- it will be made available to SDR Forum members for a six-month period, after which, it will be available to the entire industry to download from the SDR Forum and CRC Web sites.
"This is an exciting effort because the SCA is a key element of SDR technology as it promotes communications interoperability and air interface portability between manufacturers, two essential aspects for the military and public safety organizations," said Claude Belisle, Manager of the Advanced Radio System Research group at CRC. "The full potential of the SCA can only be reached if the industry first starts out with a proper building block -- a well-defined, cost-effective and time-efficient reference implementation." Belisle also noted that CRC will collaborate with an international team to develop v.2.2 that includes Rohdes and Schwarz, ISR Technologies, Ecole Technologies Superieures, Mercury Computer, NASA and JTRS.
Note to developers:
The SDR Forum/CRC collaboration to develop the industry's first Java-based, open source reference implementation for version 2.1 of the SCA is available for free on the CRC's website (www.crc.ca/rars) and has received more than 7,000 downloads to date.
About the SCA
Developed under the DoD's Joint Tactical Radio System (JTRS) program with key input provided by the SDR Forum, the SCA is a set of specifications that describes the interaction between software and hardware components of an SDR and provides software commands to control its function. The SCA supports the JTRS mission to ensure that SDR devices from different manufacturers can effectively and efficiently communicate with each other.
About the Software Defined Radio Forum
The Software Defined Radio Forum is an international industry association dedicated to supporting the development and deployment of software defined radio systems that enable flexible and adaptable architectures in advanced wireless systems. The membership of the SDR Forum spans commercial, defense, and civil government organizations, and includes wireless service providers, network operators, component and equipment manufacturers, hardware and software developers, regulatory agencies, and academia. Presently numbering more than 100 organizations, the SDR Forum's membership includes major commercial wireless players from Asia, Europe, and North America. The SDR Forum's administrative office is headquartered in Denver, Colorado. Additional information is available on the SDR Forum website at www.sdrforum.org.
About the Communications Research Centre Canada (CRC)
CRC is the Canadian government's primary laboratory for research and development (R&D) in advanced telecommunications. R&D is used for public policy purposes and to strengthen the Canadian economy through technology and knowledge transfer. Under its four research branches (Terrestrial Wireless, Satellite Communications and Radio Propagation Research, Broadband Network Technologies and Broadcast Technology), CRC specializes in taking an interdisciplinary approach to longer-term R&D in wireless systems, radio fundamentals, communication networks, photonics and interactive multimedia.
