A communication device comprises one or more sensors configured to generate sensor data, a wireless interface, and a processor. The wireless interface is configured to establish a connection with a remote device according to a short-range wireless communication protocol and to transmit one or more signals to the remote device, the one or more signals representing information configured according to a media format. The processor is configured to determine at least one activity mode based on the sensor data from the one or more sensors on at least one of the communication device or the remote device, and during the transmission of the one or more signals, control the wireless interface to increase a transmit power level to a maximum transmit power level based on the determined activity mode.

Selective direct increase of transmit power level of a wireless communication device to a maximum power level based on detected activity mode or received signal quality

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

A method for generating a geofence includes receiving, at an automated frequency coordination (AFC) system, a geofence request from an AFC device where the geofence request requests to use a licensed radio frequency band and includes one or more operating parameters for the AFC device. The method also includes determining, by the AFC system, whether any of the one or more operating parameters interfere with any licensed devices on the licensed radio frequency band. When none of the one or more operating parameters interfere with any of the licensed devices on the licensed frequency band, the method further includes generating, by the AFC system, based on the one or more operating parameters, a geofence defining an operating boundary for the AFC device to communicate within. The method also includes communicating, from the AFC system to the AFC device, a response to the geofence request where the response includes the geofence.

Reverse geofence feature in an automated frequency coordination system

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 wireless communication device (alternatively, device) includes a processor configured to support communications with other wireless communication device(s) and to generate and process signals for such communications. In some examples, the device includes a communication interface and a processor, among other possible circuitries, components, elements, etc. to support communications with other device(s) and to generate and process signals for such communications. A device generates and transmits a resource and association poll frame (ra-poll frame) to other device(s). The contents of ra-poll frame direct which of the other device(s) is authorized to respond to the device (e.g., authorized device(s)) and the manner in which they are authorized to respond. Authorized device(s) transmit responses that may include association request(s) and/or a resource request(s), among other types of communications. The device then generates and transmits acknowledgement(s) (ACK(s)) indicates successful receipt of any responses from the authorized device(s).

Mechanisms for single user (SU) and multiple user (MU) transmission and association via polling within wireless communications

Coordination and synchronization is performed between two or more wireless network managers (e.g., access points (APs)). A first wireless network manager supports first communications with first other wireless communication devices, and a second wireless network manager supports second communications with those first and/or second other wirelessly case devices. The first and second wireless network managers also support communications with one another to coordinate the first and second communications supported with the first and/or second other wireless communication devices. Examples of coordination include selection of which other wireless communication devices are serviced or in communication with which of the first and second wireless network managers, selection of operational parameters (e.g., modulation coding set (MCS), beamforming, frequency band assignment, channel assignment, scheduling information, transmit power, etc.) for the first and second wireless communication devices, synchronization to a common clock (e.g., using timing synchronization function (TSF)).

Inter-AP coordination and synchronization within wireless communications

A wireless communication device is implemented to include a communication interface and a processor. The processor is configured to process communications associated with the other wireless communication devices within the wireless communication system to determine one or more traffic characteristics of those communications as well as one or more class characteristics of the other wireless communication devices. The processor is configured to classify the communications into one or more access categories based on the one or more traffic characteristics and is configured to classify the other devices into one or more device class categories based on the one or more class characteristics. The processor is then configured to generate one or more channel access control signals based on these classifications. The communication interface of the device is configured to transmit the one or more channel access control signals to one or more of the other devices.

Multiple narrow bandwidth channel access and MAC operation within wireless communications

A wireless communication device includes a communication interface and a processor that operate to generate a first transmission stream by processing first information based on first parameter(s) and a second transmission stream by processing second information based on second parameter(s). In some examples, the second at least one parameter is relatively less robust than the first at least one parameter, and the second information augments the first information when combined with the first information. The wireless communication device then transmits the first transmission stream and the second transmission stream to at least one other wireless communication device. Examples of such parameters include forward error correction (FEC) code, error correction code (ECC), modulation coding set (MCS), modulation type including a mapping of constellation points arranged in a constellation, power (e.g., transmit (TX) power), orthogonal frequency division multiplexing (OFDM) configuration, and/or a multiple-input-multiple-output (MIMO) configuration.

Hierarchical transmission in wireless communications

A communication device includes a processor configured to generate OFDMA packets using various OFDMA packet structures and to transmit such OFDMA packets, via a communication interface, to at least one other communication device. The processor is also configured to receive, interpret, and process such OFDMA packets. One example of an OFDMA packet includes common SIG for two or more other wireless communication devices modulated across all sub-carriers of the OFDMA packet. The common SIG is followed by first SIG and first data for a first other wireless communication device modulated across first subset of the sub-carriers of the OFDMA packet and is also followed by second SIG and second data for a second other wireless communication device modulated across second subset of the sub-carriers of the OFDMA packet. Another example of an OFDMA packet includes the common SIG followed directly by first data and second data modulated as described above.
