PISCATAWAY,
N.J., USA, 6 May 2004 The IEEE has approved the start of work
on four projects concerning IEEE 802.15(TM) 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(TM),
"Recommended Practices for Mesh TopologyCapability 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(TM), "Medium Access Control (MAC) and Physical
Layer (PHY)
Specifications: Amendment to MAC Sublayer," will modify IEEE
802.15.3(TM)
to improve the ease of implementation and interoperability.
This will
include minor optimizations while preserving backward compatibility.
In addition, this amendment will correct errors, clarify ambiguities,
and add editorial clarifications. IEEE P802.15.4a(TM), "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(TM),
"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(TM)-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 (IEEE-SA), a global standards-setting
body, develops consensus standards through an open process that
brings diverse parts of an industry together. It has a portfolio
of more than 870 completed standards and more than 400 in development.
IEEE-SA promotes the engineering process by creating, developing,
integrating, sharing and applying knowledge about electro- and
information technologies and sciences for the benefit of humanity
and the profession. For further information on IEEE-SA visit:
