The disclosed subject matter includes techniques for wireless communication. In one example, a system includes a processor and a computer-readable memory storage device for storing executable instructions that can be executed by the processor to cause the processor to send a data frame to a client device. The processor can also receive a data-acknowledgment frame from the client device in response to the data frame within a predetermined time after sending the data frame. The processor can also aggregate a response data-acknowledgment frame in response to receiving the data-acknowledgment frame with at least one data frame to form an aggregated frame. The processor can also further send the aggregated frame to the client device and the at least one other client device within the predetermined time after receiving the data-acknowledgement frame.

Wireless data-acknowledgement communication using frame aggregation

Various systems and methods for transmitting data are described herein. In one example, a method includes detecting a plurality of data frames to be transmitted using a shared communication network and selecting a first and a second data frame from the plurality of data frames based on a deadline for each of the plurality of data frames. The method also includes transmitting, via a shared communication network, the first data frame to a first client device and waiting for a predetermined delay period. Additionally, the method includes detecting a data acknowledgement frame from the first client device and transmitting, via the shared communication network, the second data frame to a second client device, the first data frame and the second data frame to be transmitted sequentially. Furthermore, the method includes transferring control of the shared communication network to an external device.

Data acknowledgment to multiple devices

Example apparatus and methods concern establishing, maintaining, managing, or terminating communications between an access point and a client in a wireless network used by a shared, wireless gaming system. An example apparatus may include a first logic configured to control timing for the protocol and a second logic configured to control message exchange for the protocol. Controlling timing and message exchange facilitates reducing contention in the wireless gaming environment. Contention may lead to latency. A user gaming experience may depend on reducing latency. Therefore, reducing latency may produce an improved gaming experience. Controlling timing and message exchange also facilitates reducing power consumption by clients (e.g., accessories, controllers), which in turn facilitates improving battery life for clients.

Wireless gaming protocol

The disclosed subject matter includes techniques for delaying network frames. In some examples, a system for delaying network frames can include a processor and a computer-readable memory storage device for storing executable instructions that can be executed by the processor to cause the processor to identify a network frame to be transmitted to a host device at a client device. The processor can also delay transmission of the network frame to the host device based at least on the network information and a frame deadline.

Wireless communication using delayed frame transmission

A wireless controller includes a handle portion to be held in one or both hands. The wireless controller also includes a gyroscope to output rotation information indicative of rotation of the handle about a steering axis, an accelerometer to output acceleration information, and a magnetometer to output magnetic bearing information. The wireless controller also includes a communication subsystem to wirelessly transmit sensor data to a computing device. The sensor data represents one or more of the rotation information, the acceleration information, and the magnetic bearing information such that the acceleration information is useable to attenuate gyroscopic drift when the handle has a first orientation and the magnetic bearing information is useable to attenuate gyroscopic drift when the handle has a second orientation.

Wireless controller

The disclosed subject matter includes techniques for performing a channel availability check. A method includes initiating, via a processor of a master device, a first connection on a first wireless channel with a subordinate device and transmitting, via the processor, a beacon to the subordinate device. The method includes monitoring, via the processor, the first wireless channel for a first predetermined amount of time for a connection request from the subordinate device in response to the beacon. The method includes performing the channel availability check to detect energy profiles on a second wireless channel for a second predetermined amount of time after the first predetermined amount of time. The processor may cycle between transmitting the beacon and monitoring the first wireless channel and performing the channel availability check on the second wireless channel until a threshold time is exceeded, the connection request is detected, or an energy profile is detected.

Channel availability checks with device monitoring

A system and method for preventing a wireless controller system and WiFi radio system within a game console from interfering with each other. Specifically, the WiFi system is adapted to avoid activating its transmitter during the controller receive times by detecting a signal sent to the WiFi module indicating where the controller receive times occur without an explicit signal indicative of the controller receive times.

RF collaboration method to reduce RF interference with wireless adapter

A mobile device includes a magnetometer. The mobile device is calibrated during application usage by sampling magnetic information received from the magnetometer, recognizing an initial controller orientation signal derived from a first sample of a plurality of samples of the magnetic information and from directional offset data, calculating updated directional offset data based on the plurality of samples of the magnetic information and on the directional offset data, and deriving a calibrated controller orientation signal from a second sample of the plurality of samples of the magnetic information and the updated directional offset data.

Dynamic magnetometer calibration

A computing device receives acceleration information from an accelerometer mechanically coupled to a wireless controller, magnetic bearing information from a magnetometer mechanically coupled to the wireless controller, and rotation information from a gyroscope mechanically coupled to the wireless controller. When the wireless controller is primarily vertical, the computing device determines a rotation angle of the wireless controller by filtering the rotation information using the acceleration information. When the wireless controller is primarily horizontal, the computing device determines the rotation angle of the wireless controller by filtering the rotation information using the magnetic bearing information.

Embodiments related to calibrating a game controller including a magnetometer during game play are disclosed. One embodiment provides a method comprising sampling magnetic information received from the magnetometer, and outputting, to a computing device, an initial game controller orientation signal derived from a first sample of a plurality of samples of the magnetic information and from directional offset data. The method further comprises calculating updated directional offset data based on the plurality of samples of the magnetic information and on the directional offset data, and outputting to the computing device a calibrated game controller orientation signal derived from a second sample of the plurality of samples of the magnetic information and the updated directional offset data.
