Abstract: Examples include classifying high frequency radio signals. Some examples include receiving a fast Fourier transform (FFT) of a high frequency radio signal, determining a first signal strength at a first guard frequency bin, determining a second signal strength at a second guard frequency bin, and determining a third signal strength at a direct current carrier frequency bin. Examples also include classifying the high frequency radio signal based on the first signal strength, the second signal strength, and the third signal strength.

Abstract: Embodiments are directed to interference-aware link-rate adaptation for wireless communication. An embodiment of a storage medium includes instructions to operations including receiving data regarding wireless signals received by an access point, the access point to provide Wi-Fi communication, the wireless signals being communicated in an unlicensed radio spectrum; performing spectral analysis of the received wireless signals to identify a channel of an LTE (Long-Term Evolution) signal; and upon determining that energy level of the LTE signal is below an energy detection (ED) level and that the channel is a primary Wi-Fi channel for the access point, adapting a link rate for the access point based on channel state information for the channel.

Abstract: Embodiments are directed to multi-user virtual reality over wireless networks. An embodiment of a storage medium includes instructions for receiving a request at a network device for a virtual reality (VR) operation, the VR operation to serve VR client devices utilizing a wireless communication network; obtaining statistics regarding the wireless communication network and the VR client devices, the statistics including data transmission rates and data transmission quality; exposing the statistics to a server to assist with optimization of the wireless communication network; and facilitating optimization of the wireless communication network for multi-user VR operation based at least in part on the statistics.

Abstract: A method of adjusting a communication link of a client device of a wireless local area network is described. The method includes monitoring two or more communication links between two or more client devices and a network device in a wireless local area network. The two or more client devices including a first client device and a second client device. The method also includes detecting a degradation in a first communication link between the first client device and the network device. The communication link degradation is not detected in a second communication link between the second client device and the network device. The method further includes determining the degradation in the first communication link is caused at least in part by interference from cellular network communications. The method includes adjusting one or more parameters of the first communication link without affecting the second communication link in response to determining the degradation is cause at least in part by the interference from the cellular network communications.
