Abstract: A method can include, in an access point (AP) configured to control data transfers for associated stations (STAs) in time intervals, storing a unique identifier and quality-of-service (QoS) requirement for each STA of a first set in a nonvolatile memory of the AP. In response to a STA associating with the AP, if the associating STA is in the first set, allocating time for the STA in the time intervals to meet the QoS requirement of the STA without receiving transmitted QoS data from the STA, and if the associating STA is not in the first set, establishing a QoS for the STA having a lower priority than any associated STAs of the first set. Corresponding systems and devices are also disclosed.

Abstract: A method includes transmitting one or more segments of a security certificate on a wireless advertising channel of a peripheral device, where at least one of the segments of the security certificate identifies an authentication server, participating in a public key exchange between the peripheral device and a host device by transmitting a signed public key of the peripheral device, where the signed public key is signed in the security certificate, and transmitting one or more encrypted messages from the peripheral device to the host device via a first secure connection established based on the public key.

Abstract: A device may generate network profile data indicating a set of network parameters detected by the device. The device may encrypt the network profile data and may transmit the encrypted network profile data to a network device, such as a router, or a server. The router or server may analyze the encrypted network profile data to determine if the device is secure. The router of server may perform one or more security measures if the device is not secure.

Abstract: A method can include at a first station in a wireless network, receiving path loss (PL) transmissions from at least a second station, dynamically changing power for transmissions from the first station to the second station based on the received PL information, determining PL values for transmissions received at the first station from other stations, and sending PL transmissions from the first station that include the determined PL values for at least one other station. The PL transmissions are configured to be received by stations of the same wireless network and stations of a different wireless network. Corresponding devices and systems are also disclosed.

Abstract: In general, techniques are described by which to perform secure fine time measurement for wireless communication protocols. An initiating station comprising wireless communication circuitry may be configured to perform the techniques. The wireless communication circuitry may be configured to receive, in accordance with a wireless networking protocol for communicating between the initiating station and a responding station, a first fine time measurement specifying a first time. The wireless communication circuitry may also be configured to receive, in accordance with the wireless networking protocol and for the corresponding first time, a first message integrity code. The wireless communication circuitry may next be configured to authenticate, based on the first message integrity code, the responding station to establish that the fine time measurement is from a trusted responding station.
