    Abstract: A communication relay apparatus of an embodiment includes an antenna, a signal intensity detector, a first search unit, and a second search unit. The antenna forms a beam of radio waves in an arbitrary direction. The signal intensity detector detects an intensity of a signal received by the antenna. The first search unit changes a direction of the beam formed by the antenna within a first range, and detects a direction in which the mobile station is located based on the intensity of the signal detected by the signal intensity detector. The second search unit changes a direction of the beam formed by the antenna within a second range narrower than the first range, and detects a direction in which the mobile station is located based on the intensity of the signal detected by the signal intensity detector.

    Abstract: An apparatus and method for estimating the direction of an RF signal is provided. The apparatus includes an antenna for receiving an RF signal. An electronic compass is configured to, as a pointing direction of the antenna is varied, generate information about pointing directions and pointing angles corresponding to variations in the pointing direction of the antenna. A control unit determines RSSI values at respective pointing angles of the antenna based on a received signal of the antenna and information of the electronic compass depending on the variations, extracts a maximum RSSI value from the RSSI values at respective pointing angles, and stores the maximum RSSI value and a pointing direction corresponding to the maximum RSSI value. A display unit displays the RSSI values at the respective pointing angles and a trajectory of the RSSI values at respective pointing angles under control of the control unit.
