Abstract: This disclosure describes, in part, techniques for switching between communication channels in order to reduce latency of data transmissions. For instance, an electronic device may establish a first network connection with a network device and second network connection(s) with other electronic device(s). The electronic device may then send data received from the network device to the other electronic device(s). In some circumstances, the electronic device may establish a new network connection with the network device, such as on a different communication channel and/or use a different network band. In such circumstances, the electronic device may use one or more techniques to establish new network connections(s) with the other electronic device(s) in order to reduce the latency it takes to send the data received from the network device to the other electronic device(s).

Abstract: Techniques for performing high-precision presence detection by establishing and monitoring peer-to-peer communication links between user devices residing in a same physical environment. A user device that resides in the environment may establish communication links with multiple other user devices residing in the environment. The user device may monitor the channel properties for those communication links to detect fluctuations in the channel properties caused by a user moving through a signal of the communication links. In examples where the user device detects fluctuations in channel properties for multiple communication links, the user device may determine that the user had moved though signals of the communication links. The user device may determine that, because the user moved through signals of multiple communication links, the user may be in close proximity to the user device, such as in the same room.

Abstract: Technologies directed to Dynamic Frequency Selection (DFS) channel assessment mechanisms are described. A processing device of a first wireless device identifies a channel identifier corresponding to a first operating channel being used by a first radio of the first wireless device to communicate with a first access point (AP) enabled on a radio of a second wireless device. The processing device identifies multiple devices in proximity to the first wireless device using a second radio. The processing device determines an airtime utilization percentage value for each operating channel of the second radio and determines a number of radar events for each DFS channel. The processing device determines a second channel identifier having a fewest number of radar events and selects a second operating channel for a second AP on the second radio, the second channel corresponding to the second operating channel.

More particularly, an access point (AP) identifies a plurality of multi-user multiple-input multiple-output (MU-MIMO) groups associated with a wireless station (STA).
