Wi-fi standard is approved
On September 11, 2009 the IEEE finally ratified 802.11n technology, a wi-fi standard that has been utilised for many years.
The IEEE’s Standards Board ratified the IEEE 802.11n-2009 amendment, defining mechanisms that provide significantly improved data rates and ranges for wireless local area networks (WLANs). The new amendment to the IEEE 802.11 base standard is designed to help the data communications industry address the escalating demands placed on enterprise, home and public WLANs with the rise of higher-bandwidth file transfers and next-generation multimedia applications. The IEEE claims WLANs based on IEEE 802.11 are widely deployed, with more than 1 million units shipping per day.
The IEEE 802.11 standard defines how to design interoperable WLAN equipment that provides a variety of capabilities including a wide range of data rates, quality of service, reliability, range optimisation, device link options, network management and security.
More than 400 individuals from equipment and silicon suppliers, service providers, systems integrators, consultant organisations and academic institutions from more than 20 countries participated in a seven-year effort leading to IEEE 802.11n’s ratification. Publication of the amendment is scheduled for mid-October.
"This was an extraordinarily wide-ranging technical challenge that required the sustained effort and concentration of a terrific variety of participants. When we started in 2002, many of the technologies addressed in 802.11n were university research topics and had not been implemented," said Bruce Kraemer, chair of the IEEE Wireless LAN Working Group. "The performance improvements achieved via IEEE 802.11n stand to transform the WLAN user experience, and ratification of the amendment sets the stage for a new wave of application innovation and creation of new market opportunities."
Paul Nikolich, IEEE 802 LAN/MAN Standards Committee chairman, congratulated everyone involved in the 802.11n process, pinpointing Kraemer’s contribution. "[Kraemer’s] strong leadership has been instrumental from the start," he enthused, adding: "The amendment will enable a dramatic leap forward in WLAN scalability with only a modest associated rise in costs for the industry and end users."
