Claim:
1. A wireless communication apparatus for a vehicle comprising: a receiver receiving information transmitted from each of a plurality of external communication apparatuses via a wireless communication, the plurality of external communication apparatuses being located outside of a host vehicle to which the wireless communication apparatus is provided; a distance calculation section calculating a distance between the host vehicle and each of a plurality of outside targets based on position determination information under a condition that the information transmitted from each of the plurality of external communication apparatuses includes the position determination information, the plurality of outside targets being located around the host vehicle and being provided with the plurality of external communication apparatuses, respectively, and a position of each of the plurality of outside targets being specified based on the corresponding position determination information; a reception frequency changing section decreasing an information reception frequency of the receiver in accordance with an increase in the distance between the host vehicle and one of the plurality of outside targets, which is located closest to the host vehicle; and a communication section communicating with a display apparatus, wherein the display apparatus includes a screen that displays the position of each of the plurality of outside targets and a position of the host vehicle in accordance with the position of each of the plurality of outside targets and the position of the host vehicle, and the position of each of the plurality of outside targets is determined based on the corresponding position determination information received by the receiver; and a display state determination section determining whether the position of each of the plurality of outside targets is in a display state or in a non-display state on the screen of the display apparatus based on display state information that is acquired by the communication section from the display apparatus; wherein the reception frequency changing section decreases the information reception frequency of the receiver in a case where the display state determination section determines that the position of each of the plurality of outside targets is in the non-display state compared with a case where the display state determination section determines that the position of each of the plurality of outside targets is in the display state.
