摘要： A radio base station performs wireless communication with a wireless terminal. The radio base station includes a directivity pattern specifying unit, a communication unit, and a signal processor. The directivity pattern specifying unit specifies plural directivity patterns. The communication unit receives a search request frame from the wireless terminal, sends to the wireless terminal a search response frame which is a response to the search request frame, with at least one, specified by the directivity pattern specifying unit, of the directivity patterns, and receives a delivery acknowledgment frame for the search response frame from the wireless terminal with the directivity patterns specified by the directivity pattern specifying unit. The signal processor calculates, for each specified directivity pattern, a radio wave intensity of the delivery acknowledgment frame.
