IEEE Begins Standard To Optimize Radio/Spectrum Usage In Wireless Networks

Source: IEEE
Piscataway, NJ -- The IEEE P1900.4 Working Group, which will create a standard to optimize radio usage and improve the overall capacity and quality of service of wireless systems in a multiple radio access technologies environment, held its first meeting on February 6 to 8 in Madrid, Spain.

The group approved the content of a baseline document for IEEE P1900.4 at the meeting and elected Soodesh Buljore, PhD, of Motorola as chair and Patricia Martigne of France Telecom as vice-chair. The meeting was hosted by Telefónica Investigación y Desarrollo and was attended by regulators, operators, equipment manufacturers and those in academia involved in next-generation radio and spectrum management for wireless communication networks.

The next working group meeting will occur March 27 to 29 in London, England. IEEE P1900.4 is being developed within the IEEE Standards Association Corporate Standards Program, which offers a streamlined, corporate-focused approach to standards development. The standard is scheduled for completion in February 2009.

IEEE P1900.4, "Architectural Building Blocks Enabling Network-Device Distributed Decision Making for Optimized Radio Resource Usage in Heterogeneous Wireless Access Networks", will address the functional architecture of the overall system, information exchange, and seamless handover between a network and the devices using it.

"In addressing these areas, the standard will provide much needed procedures that allow multimodal devices to make optimal choices among available radio resources," said Soodesh Buljore, Chair of the IEEE P1900.4 Working Group. "It also will let such devices use several of these resources simultaneously to improve the efficiency and capacity of the composite network."

Three primary use cases were identified at the Madrid meeting - dynamic spectrum allocation, dynamic spectrum access, and distributed radio resource usage optimization. These scenarios are intended to improve overall wireless system capacity and quality of service in a multiple radio access environment. The system architecture and protocols selected will help optimize radio resource usage by exploiting information exchanged between a network and mobile terminals. This capability for radio resource optimization extends to the support of multiple, simultaneous links and dynamic spectrum access.

Organizations that have joined the IEEE P1900.4 Working Group include Alcatel-Lucent, BAE Systems, France Telecom, Intel, Kings College London, Motorola, National Institute of Information and Communications Technologies, Ofcom, Research In Motion, Telefónica I+D, Toshiba, the University of Piraeus and the Universitat Politècnica de Catalunya.

IEEE P1900.4 is sponsored by the IEEE Communications Society and the IEEE Electromagnetic Compatibility Society. IEEE is taking a leading role in defining dynamic spectrum access and cognitive radio standards since March 2005, with the initiation of IEEE P1900.1 which defines standard terms and definitions. Two other standards projects, P1900.2 and IEEE P1900.3 address interference and coexistence as well as conformance evaluation of modules respectively.
