IEEE 802.19 is the Wireless Coexistence Technical Advisory Group (TAG) within the IEEE 802 LAN/MAN Standards Committee. The TAG deals with coexistence between unlicensed wireless networks. Many of the IEEE 802

IEEE 802

IEEE 802 refers to a family of IEEE standards dealing with local area networks and metropolitan area networks.More specifically, the IEEE 802 standards are restricted to networks carrying variable-size packets. IEEE 802 refers to a family of IEEE standards dealing with local area networks and...

 wireless standards use unlicensed spectrum and hence need to address the issue of coexistence. These unlicensed wireless devices may operate in the same unlicensed frequency band in the same location. This can lead to interference between these two wireless networks.

Background

Two unlicensed wireless networks are said to coexist if they can operate in the same location without causing significant interference to one another. One of the first examples of wireless coexistence was between IEEE 802.11

Overview

Currently the 802.19 TAG addresses coexistnece between wireless standards under development within IEEE 802. There are a number of working groups within IEEE 802 which are developing standards for unlicensed wireless network. These include

  Wireless Regional Area Networks (WRAN)

When a new standard (or amendement to a standard) for an unlicensed wireless network is being developed the working group may develop a Coexistence Assurance (CA) document that is reviewed the IEEE 802.19 TAG.

The TAG is currently evaluating the coexistence between IEEE 802.11y and IEEE 802.16h, both operating in the 3650 MHz frequency band.
