Examples disclosed herein relate to determining a scale associated with received signal strength indicators (RSSIs). In one example, a computing device receives access point (AP) RSSIs. The RSSIs are determined at APs. The APs are associated with coordinate information. In one example, records are maintained for AP reference pairs. Each AP RSSI can be determined at one AP with reference to another AP. In one example, the computing device determines a scale associated with each record.

Disclosed are techniques for performing ranging operations between an access point and an unassociated mobile device. The techniques can include receiving, at an access point, a broadcast probe request from a mobile device unassociated with the access point. In response to receiving the probe request, it can be determined that the mobile device is capable of performing ranging operations including inspecting the received broadcast probe request. The access point can send a ranging request to the mobile device.

Examples relate to access point signal estimation. In one example, a computing device may: receive a first pathloss value in a first frequency, the first pathloss value indicating a difference in transmit power of a particular access point and a received signal strength observed by a first access point; receive a second pathloss value in the first frequency, the second pathloss value indicating a difference in transmit power of the particular access point and a received signal strength observed by a second access point; receive a third pathloss value in a second frequency, the third pathloss value indicating a difference in transmit power of the particular access point and a received signal strength observed by the second access point in the second frequency; and generate, using the first, second, and third pathloss values, an estimated pathloss between the first access point and the particular access point in the second frequency.

Wi-Fi channels are automatically selected in a WLAN controller based deployment. Scan results received from each of the plurality of access points comprise a list of neighboring access points from the plurality of access points relative to each access point. Responsive to a number of the plurality of access points exceeding a number of non-interfering channels, assigning each of the plurality of access points to a non-interfering channel with sharing of at least one of the non-interfering channels, using a GCA (Graph Coloring Algorithm) in which each color assignment corresponds to a non-interfering channel assignment in order to prevent neighboring access points from sharing a non-interfering channel. Lowest RSSI measurements collected by access points can also be a factor in channel selection.

A cooperative wireless system using a multicast protocol to facilitate coordinating coherent addition and subtraction of wireless signaling or other beams originating from a plurality of antenna units at a target location is contemplated. The system may utilize multicast-based regulation and distribution of transmission control parameters necessary for the antenna units to synchronize the wireless signaling in a manner sufficient to enable the coherent addition and subtraction thereof at the target location.
