IEEE okays base-line for possible P1900.4 standard

In its first meeting this month, the IEEE P1900.4 working group approved the content of a baseline document for the standard. The body also elected Soodesh Buljore of Motorola as chairman and Patricia Martigne of France Telecom as vice chairman of the working group.

IEEE P1900.4 or the 'Architectural building blocks enabling network-device distributed decision making for optimised 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 multi-modal devices to make optimal choices among available radio resources," said Buljore, chairman 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."

The group identified three primary use cases for the standard—dynamic spectrum allocation, dynamic spectrum access and distributed radio resource usage optimisation.

The three scenarios aim to improve overall wireless system capacity and QoS in a multiple radio access environment. The system architecture and protocols selected will help optimise radio resource usage by exploiting information exchanged between a network and mobile terminals. This capability for radio resource optimisation extends to the support of multiple, simultaneous links and dynamic spectrum access.

Organisations that have joined the working group include Alcatel-Lucent, BAE Systems, Intel, Kings College London, National Institute of Information and Communications Technologies, Ofcom, Research In Motion, Telefonica I+D, Toshiba, the University of Piraeus and the Universitat Politecnica de Catalunya.

The working group will have its next meeting on March 27-29 in London.
