Abstract
A wireless communication apparatus includes an acquisition unit, a calculation unit, a selection unit, and a notification unit. The acquisition unit acquires location information of a first terminal and a second terminal that perform terminal-to-terminal communication without using a base station. The calculation unit calculates a distance between the first and second terminals based on the acquired location information of the first and second terminals. The selection unit selects a frequency to be used for the terminal-to-terminal communication based on the distance calculated by the calculation unit. The notification unit notifies the first and second terminals of a start of the terminal-to-terminal communication and the selected frequency.
