IEEE amends wireless, municipal network standards

To promote interoperability for access points in wireless local area networks (WLANs) and help users evaluate wireless municipal area network (WMAN) products, the Institute of Electrical and Electronics Engineers Standards Association (IEEE-SA) announced July 30 that it has approved amendments to two wireless networking standards.

To promote interoperability for access points in wireless local area networks (WLANs) and help users evaluate wireless municipal area network (WMAN) products, the Institute of Electrical and Electronics Engineers Standards Association (IEEE-SA) announced July 30 that it has approved amendments to two wireless networking standards.

The first, IEEE 802.11F, sets specifications so access point devices from different vendors in IEEE 802.11 WLANs can interoperate. The other, IEEE 802.16/Conformance01, allows end-users to evaluate how well a product designed for IEEE 802.16 WMAN conforms to the standard.

IEEE 802.11F, entitled ”Recommended Practices for Multi-Vendor Access Point Interoperability via Inter-Access Point Protocol Across Distribution Systems Supporting IEEE 802.11 Operations,” adds definitions for access points and distribution systems absent from the IEEE 802.11 standard.

The lack of such definitions in the base standard allowed for flexible distribution system and access point design, but access point devices having different approaches often could not interoperate across a distribution system. This has impeded the growth of the WLAN market. IEEE 802.11F corrects this by specifying the information exchange needed between access points so distribution systems with different access points can work together.

Meanwhile, IEEE 802.16/Conformance01, entitled ”Protocol Implementation Conformance Statement (PICS) Proforma for 10-66 GHz WirelessMAN-SC Air Interface,” contains a document to be filled out by product suppliers who claim to implement the standard. This conformance statement allows end-users to evaluate how well a product meets their requirements. The statement is in accord with ISO/IEC Standard 9646-7 (1995) and ITU-T X.296, which provide conformance specifications for base stations and subscriber stations based on the 10-66 GHz air interface in IEEE 802.16.

Both IEEE 802.11 and IEEE 802.16 standards are sponsored by the IEEE Computer Society.
