A wireless communication device identifies an access point for a wireless network. The device initiates a connection procedure to establish a wireless connection between the wireless communication device and the access point, and the connection procedure includes: (i) selecting a degraded set of uplink transmission quality parameters that correspond to a higher signal-to-noise (SNR) ratio than a baseline set of uplink transmission quality parameters, and (ii) transmitting messages from the wireless communication device to the access point during the connection procedure according to the degraded set of uplink transmission quality parameters. The wireless network connection can be established between the wireless communication device and the access point as a result of completion of the connection procedure, despite the wireless communication device transmitting messages to the access point during the connection procedure according to the degraded set of uplink transmission quality parameters.

Establishing and terminating wireless links

An access system for a wireless local area network is provided. The access system initiates operation in a first frequency band of a plurality of frequency bands of the wireless local area network to provide one or more wireless client devices of the wireless local area network with access to a wireless wide area network. The access system also processes one or more association requests received in the first frequency band to identify one or more associated wireless client device. The access system also determines whether each of the one or more associated wireless client devices supports a second frequency band. The access system also sends a request to the one or more associated wireless client devices to transition from the first frequency band to the second frequency band based on determining that each of the one or more associated wireless client devices supports the second frequency band.

Intelligent band selection for wireless access point

A Bluetooth Low Energy (BLE) device may collect one or more resolvable public identifiers from one or more wireless devices, each of the resolvable public identifiers indicating whether a user associated with a respective one of the wireless devices is a possible virus carrier. The BLE device may generate a timestamp for each of the collected resolvable public identifiers, each timestamp indicating a time at which a corresponding resolvable public identifier was received by the BLE device. The BLE device may share the collected resolvable public identifiers and their corresponding timestamps with a paired device. The BLE device may receive, from the paired device, an indication of whether one or more of the collected resolvable public identifiers is associated with a possible virus carrier. The BLE device may be included within or attached to one of a bracelet, neckless, a belt, watch, a smartwatch, or a key fob.

Wireless contact tracking

Methods and devices are described for wireless communications associated with a multidimensional algorithm for roaming. In one aspect, an access point (or like device) transmits a beacon signal. The access point receives, from a station in receipt of the beacon signal, a probe signal including at least one metric. The access point transmits a response signal based at least in part on the received probe signal, the response signal including information associated with the at least one metric.

Multidimensional algorithm for roaming

A method for determining a frequency usage pattern of one or more satellites includes receiving, at data processing hardware, identifications of one or more satellite communication frequencies used by a satellite at corresponding locations of the satellite along a non-geostationary satellite orbit. The method includes determining, by the data processing hardware, a pattern of frequency usage by the satellite at the corresponding locations of the satellite. The method also includes instructing, by the data processing hardware, communication between a high altitude platform and a ground terminal using an identified satellite communication frequency during a non-interfering period of time based on the pattern of frequency usage by the satellite. The high altitude platform has an altitude lower than the satellite.

Reusing frequencies among high altitude platforms

Methods, systems, and devices are described for power conservation in a wireless communications system. In embodiments, power conservation may be achieved by adaptively controlling power modes of a wireless communication device, using a modulation and coding scheme (MCS) value as a factor for guidance. According to one aspect, the device may be in a reception mode. While in a first power mode, the device may receive control information for incoming data that is being transmitted via a transmission frame. The control information may be located in a first portion of the frame with the data following in a second portion of the frame. The control information may include or otherwise indicate an MCS value corresponding to the MCS applied to the incoming data. Based on the MCS value, the device may be adaptively switched to a second power mode for receiving the incoming data.

Adaptive control of RF low power modes in a multi-rate wireless system using MCS value

Methods, systems, and devices are described for power conservation in a wireless communications system. In embodiments, power conservation may be achieved by adaptively controlling power modes of a wireless communication device, and implementing lower power modes with various modes of the device. According to one aspect, the mode of the device may be a beacon monitoring mode or a delivery traffic indication message (DTIM) mode. In such a mode, the device may receive a portion of a beacon in a first power mode. The device may transition to a second, different (e.g., higher) power mode using information contained in the received portion of the beacon as guidance.

Adaptive control of RF low power modes in a multi-rate wireless system using device mode

A phased-array antenna assembly includes an antenna board stack, a radome configured to cover the antenna board stack, and a casing configured to support the antenna board stack. The antenna board stack includes a central core, a bottom antenna unit defining a bottom thickness between a bottom surface of the central core and a bottom end of the antenna board stack, and a top antenna unit defining a top thickness between a top surface of the central core and the top end of the antenna board stack that is substantially equal to the bottom thickness. The bottom antenna unit includes two spaced apart bottom metal layers each associated with a different distance from the axis of symmetry. The top antenna unit includes two spaced apart top metal layers each associated with a corresponding one of the distances from the axis of symmetry associated with the bottom metal layers.

Methods, devices, and apparatuses are described for wireless communications using a multidimensional algorithm for roaming. In one aspect, an initial set of candidate access points (APs) is produced by a station using a roaming scan. The initial set may be identified based at least in part on an initial metric (e.g., beacon signal strength). A probe signal may be transmitted by the station to at least one of the candidate APs in the initial set and information may be received in response to the probe signals. The station may then identify a reduced set from the initial set based at least in part on the received information, where the reduced set is used to select a target AP. At least one additional metric may be identified and the probe signal may be configured to obtain information corresponding to the additional metrics. This information may be used by the station to select the candidate APs in the reduced set.

Systems, methods, and devices for communicating with a second apparatus in a wireless communications network are described herein. In some aspects, a first wireless communication unit is configured to communicate with the second apparatus via a first wireless protocol. The first wireless communication unit may transmit a first message to the second apparatus. A second wireless communication unit is configured to communicate with the second apparatus over a communication link via a second wireless protocol. The second wireless communication unit may be further configured to disconnect the communication link if the first wireless communication unit does not receive a second message from the second apparatus within a predetermined amount of time after transmission of the first message.

Systems and methods for secure high-speed link maintenance via NFC

A method, an apparatus, and a computer program product for wireless communication are provided in connection with reducing interference between NFC communications and other coexisting RAT based communications. In one example, a communications device may include an interface that is equipped to detect that a NFC communication and a coexisting RAT communication are to occur within a threshold time of each other, determine whether the communications will interfere with each other beyond a threshold level of interference, and align timing for the NFC communication and the RAT communication upon a determination that the communications will not interfere with each other beyond the threshold level of interference. In another example, a communications device may include an interface that is equipped to detect that a NFC subsystem has established a NFC connection, and provide a message to another RAT subsystem to establish a link or perform a handover.

Methods and apparatus for coordinating communications between a NFC radio and other coexisting RAT radios

In a multi-radio user equipment (UE) various techniques may be used to buffer communications for a first radio access technology (RAT). A low channel quality for a second RAT is reported. An indication to halt downlink communications of the second RAT based on the reported low channel quality is received. The buffered communications by the first RAT when the second RAT downlink communications are halted are transmitted. An indication to the second RAT is sent to resume normal channel quality reporting.
