IEEE 802.19 is the designation of a working group within the Institute of Electrical and Electronics Engineers (IEEE) 802 LAN/MAN Standards Committee. The group’s primary mandate is to develop technical specifications that facilitate the coexistence of heterogeneous wireless networks operating in overlapping or adjacent radio‑frequency (RF) spectrum bands.
Scope and Objectives
The working group addresses the challenges that arise when multiple wireless technologies share unlicensed or lightly licensed spectrum, such as interference mitigation, spectrum sharing policies, and coordination mechanisms. Its objectives include:
- Defining coexistence frameworks and protocols that enable disparate wireless systems to operate without detrimental mutual interference.
- Specifying measurement and testing procedures to assess coexistence performance.
- Providing guidance for regulators, manufacturers, and network operators on best practices for spectrum sharing.
Key Publication
The principal output of IEEE 802.19 is the standard IEEE 802.19.1‑2012, titled Coexistence of Wireless Networks. This document establishes a unified architecture, terminology, and set of mechanisms for ensuring that wireless networks—such as those based on IEEE 802.11 (Wi‑Fi), IEEE 802.15 (WPAN/BLE), IEEE 802.16 (WiMAX), IEEE 802.22 (TV White Spaces), and others—can coexist within the same spectral environment.
Relation to Other IEEE 802 Projects
IEEE 802.19 operates alongside other IEEE 802 task groups that develop specific wireless technologies. While groups like IEEE 802.11, IEEE 802.15, and IEEE 802.16 focus on the technical characteristics of individual radio systems, IEEE 802.19 provides cross‑technology considerations to mitigate interference when these systems are deployed in proximity.
Organizational Status
The working group is sponsored by the IEEE 802 LAN/MAN Standards Committee and reports to its Technical Steering Group (TSG). Information about the current activity status of the group (e.g., active, archived, or interim) is not publicly detailed in widely available encyclopedic sources.

Note
The term “IEEE 802.19” refers specifically to the working group and its associated standard series; it is not a standalone protocol or technology. No additional IEEE standards bearing the 802.19 prefix have been published beyond IEEE 802.19.1.
