A method is presented for dedicating and allocating frequency channels to control and data frames in a WiFi local area network system. The method comprising dedicating a frequency channel in a frequency band, determining by a station the dedicated frequency channel, transmitting by the station a probe request frame in the dedicated frequency channel, receiving by the station a probe response frame in the dedicated frequency channel.

Method of dedicating frequency channel for probing or for data

A method of determining a station distance includes a station transmitting a first message including a message frame; the station measuring a first departure time of the message frame; the station receiving a second message in response to the first message, the second message including an acknowledgement (Ack) frame including a first arrival time at which the message frame arrived and a second departure time at which the Ack frame departed; the station measuring a second arrival time at which the Ack frame arrived; and the station determining the station distance from the first departure time, the second arrival time, the received first arrival time, and the received second departure time.

Apparatus, system and method of estimating a distance between a first station and a second station

A next generation device is provided. The next generation device is configured for communicating within a wireless network including an access point (AP) supporting the next generation device. The next generation device includes a shorter Slot Time for medium access than legacy devices.

Method and apparatus for wireless communication

A communication device capable of transmitting data on a communications channel, the communications channel capable of being shared with a number of stations, the communication device being configured to determine a back-off period, the back-off period being a period of time for which the communication device delays transmission of data after determining that the communications channel is idle, wherein the communication device is configured to determine the back-off period in such a way as to favor a decrease in the back-off period in response to an increase in the number of stations.

Transmitting data

Managing access to a time-slotted communications medium by masking interrogatory codes that are contained in signals demarcating time slots of the medium and comparing the masked interrogatory codes against masked response codes. Access to the medium is dependent on the outcome of these comparisons.

Controlling stations' access to a communications medium

A system for transmitting data from two or more data streams on a communication channel between two or more devices. Roughly described, the data from each data stream is transmitted on the channel in the form of data packets, at least one data packet of one or more of the data streams being transmitted in between the data packets of the other data streams. The system is characterized in that the system comprises means to generate or process data packets for at least one of the data streams for transmission, the generated or processed data packets having a size below a certain value. Collisions between data packets of different data streams are thereby reduced.
