IEEE 802.11 Coexistence SC scope

The IEEE 802.11 WG agreed on the scope of the IEEE 802.11 Coexistence in May 2017 as:

• Discuss the use of PD, ED or other 802.11 coexistence mechanisms with the goal of promoting fair use of unlicensed spectrum
• Promote an environment that allows IEEE 802.11ax fair access to global unlicensed spectrum

The close down criteria for the IEEE 802.11 Coexistence SC was agreed to be when:

• It is determined that the SC is unlikely to make further progress towards its goals; OR
• IEEE 802.11ax completes Sponsor Ballot
