  5. Tuncer Baykas, IMU Outreach Motion • The task group directs the chair to work with the WG chair to issue a liaison request to external organizations for input on usage scenarios and technical requirements for expected use of 802.11ah and 802.15.4g sub-1GHz systems. To include requests to WiFi Alliance, 802.11ah Promotion Council, Wi-Sun Alliance, IETF 6lo and lpwan and others at the discretion of the WG and TG chairs. Motion passed
