DRAFT: 4/22/04 Contact: Karen McCabe, IEEE Marketing Manager +1 732-562-3824, [email protected] IEEE APPROVES START OF FOUR WIRELESS PERSONAL AREA NETWORK STANDARDS PROJECTS Projects Address Mesh Topologies, Enhancements for High-Speed WPANs, and an Alternate PHY for Low-Speed WPANs PISCATAWAY, N.J., USA, __ April 2004 – The IEEE has approved the start of work on four projects concerning IEEE 802.15™ wireless personal area network (WPAN) standards. These projects involve a wireless mesh topology standard for WPAN devices and alterations to the high-rate WPAN standard so it supports new wireless multimedia uses more effectively. Two other projects were started for ultra-low-power WPANs: one will create an alternate PHY and the other will correct and extend the base standard. IEEE P802.15.5™, “Recommended Practices for Mesh Topology Capability in Wireless Personal Area Networks (WPANs),” will provide an architectural framework for interoperable, stable and scaleable wireless mesh topologies for WPAN devices. Mesh topologies can extend network coverage without increasing transmission power or receiver sensitivity. They also can improve reliability via route redundancy, easier network configuration and longer device battery life. IEEE P802.15.3b™, “Medium Access Control (MAC) and Physical Layer (PHY) Specifications: Amendment to MAC Sublayer,” will modify IEEE 802.15.3 to improve the ease of implementation and interoperability. This will include minor optimizations 2 while preserving backward compatibility. In addition, this amendment will correct errors, clarify ambiguities, and add editorial clarifications. IEEE P802.15.4a™, “Wireless Medium Access Control (MAC) and Physical Layer (PHY) Specifications: Alternate Physical Layer Extension for Low Rate Wireless Personal Area Network (WPAN),” will provide an alternate WPAN PHY to meet evolving user needs for ultra-low-complexity, ultra-low-cost, ultra-low-power WPAN communications. It will provide for precision ranging accurate to one meter or less, improved communication range, improved link robustness and the ability to support mobility. It also will continue to support coexisting networks of sensors, controllers, and logistic and peripheral devices in multiple, compliant co-located systems. IEEE P802.15.4-REVb™, “Wireless Medium Access Control (MAC) and Physical Layer (PHY) Specifications for Low Rate Wireless Personal Area Networks (WPAN),” will revise the IEEE 802.15.4™-2003 standard to remove ambiguities. It also will extend the base standard by adding a method for shared time-base distribution and supporting new frequency allocations in Europe, China and Japan. These projects are sponsored by the IEEE Computer Society. About the IEEE Standards Association The IEEE Standards Association, a globally recognized standards-setting body, develops consensus standards through an open process that brings diverse parts of an industry together. These standards set specifications and procedures based on current scientific consensus. The IEEE-SA has a portfolio of more than 870 completed standards and more than 400 standards in development. Over 15,000 IEEE members worldwide 3 belong to IEEE-SA and voluntarily participate in standards activities. For further information on IEEE-SA see: http://www.standards.ieee.org/. About the IEEE The IEEE has more than 300,000 members in approximately 175 countries. Through its members, the organization is a leading authority on areas ranging from aerospace, computers and telecommunications to biomedicine, electric power and consumer electronics. The IEEE produces nearly 30 percent of the world's literature in the electrical and electronics engineering, computing and control technology fields. This nonprofit organization also sponsors or cosponsors more than 300 technical conferences each year. Additional information about the IEEE can be found at http://www.ieee.org. # # #
