From: David Spinadel <david.spinadel@xxxxxxxxx> The FCC are clarifying some soft configuration requirements, which among other include the following: 1. Indoor operation, where a device can use channels requiring indoor operation, subject to that it can guarantee indoor operation, i.e., the device is connected to AC Power or the device is under the control of a local master that is acting as an AP and is connected to AC Power. 2. Concurrent GO operation, where devices may instantiate a P2P GO while they are under the guidance of an authorized master. For example, on a channel on which a BSS is connected to an authorized master, i.e., with DFS and radar detection capability in the UNII band. See https://apps.fcc.gov/eas/comments/GetPublishedDocument.html?id=327&tn=528122 Add support for advertising Indoor-only and GO-Concurrent channel properties.
