    摘要： According to one embodiment, a wireless communication apparatus in a first wireless system is provided with first, second and third units, and a controller. The first unit transmits frames over a frequency channel using a short or long IFS as compared with a specific one used in a second wireless system with a communication range wider than the first wireless system. The second unit receives frames over the channel. The third unit determines an error characteristic in the received frames and/or a busy status of the channel. The controller controls at least either one of whether to change the frequency channel or not, and whether to change a duration of an interframe space or not.

    摘要： According to one exemplary embodiment, a communication apparatus includes: a measurement module which measures reception power of each field; a determination module which determines whether the reception power is within a range; a calculator which calculates a gain using the reception power if the reception power is not within the range; an adjuster which adjusts a field according to one of an initial gain and the calculated gain; a selector which selects a field length according to the number of field adjustments by the adjuster; and a transmitter which transmits information regarding the field length. When the number of the adjustments is lower than a first threshold value, the selector selects a first value, and when the number of the adjustments is equal to or higher than the first threshold value, the selector selects a second value that is higher than the first value, as the field length.

    摘要： A wireless communication system includes a transmitter and a receiver. The transmitter transmits signals to a receiver at a transmission interval. One of the signals is an association request signal. The transmitter includes a transmitting unit. The transmitting unit transmits the signals except the association request signal at the transmission interval of a first time interval, and transmits the association request signal at the transmission interval of a second time interval. The first time interval is different from the second time interval. The receiver includes an antenna, a receiving unit and a wake-up determining unit. The antenna receives the signals. The receiving unit performs receiving processing for the signals. The wake-up determining unit determines whether or not the signal is the association request signal based on the transmission interval. The wake-up determining unit activates the receiving unit if the signal is the association request signal.
