IEEE 802.11 Coexistence SC scope

The IEEE 802.11 WG revised the scope of the coexistance standing committee in September 2025 as follows:

Purpose

The Standing Committee (SC) is established to review and address matters related to the coexistence of IEEE 802.11 with other technologies operating in the same or adjacent spectrum, including other IEEE 802 technologies.  

Responsibilities

• Review and Discussion: The SC reviews and discusses materials and issues concerning coexistence between IEEE 802.11 and other relevant technologies including but not limited to other 802 technologie
• Advisory Role: The SC provides advice and recommendations to the IEEE 802.11 Working Group (WG) and its subgroups on matters of coexistence.
• Support in Inter-Group Coordination: The SC provides the competence to support to the IEEE 802.11 WG in formulating and developing responses to comments received from other IEEE 802 WGs regarding coexistence between IEEE 802.11 and their respective, other WGs’ technologies.
• Reporting: The SC reports on its activities and discussions to the IEEE 802.11 WG, e.g., by providing summaries of key discussion items during the WG closing plenary.
