Abstract: In an example embodiment, the orientation of a wireless device, such as an access point (AP) can be determined based on the location of neighboring wireless devices and the observed angle of arrival of signals from the wireless device at the neighboring wireless devices. For example, the angle of orientation can be determined by comparing an observed angle of arrival with the known actual angle between wireless devices. If a plurality of wireless devices measures the signal, the mean or median of the difference between observed angle of arrival of a signal from the wireless device with the actual angle for the plurality of wireless devices may be employed to determine the angular orientation.

Abstract: A device and method for tracking satellites and handing off from one satellite to another includes a linear phased array antenna capable of generating and receiving a radio signal beam and electronically pointing the beam, a first motor for tilting the antenna to mechanically point a radio signal beam generated with the antenna, a second motor for spinning or rotating the antenna to mechanically point the beam, and a controller for controlling the electronic and the mechanical pointing of the beam. The directions of the electronic and mechanical pointing of the beam is performed by selecting a certain angular profile for the second motor from the start point to the end point of the path and calculating a path of a satellite to be tracked from a start point to an end point.

Abstract: A communication system and method for controlling an antenna pattern is disclosed. The communication system may be situated on a mobile station, a base station, or a combination thereof. The communication system comprises a smart antenna module, a speed sensor, and a beam steering module. The smart antenna module may be situated on the mobile station, the base station, or a combination thereof. The smart antenna module generates at least one initial antenna pattern. The speed sensor is configured to determine a speed of a mobile station. The beam steering module generates an operating antenna pattern that is different from the initial antenna pattern. The operating antenna pattern is affected by changes in the speed of the mobile station.

Abstract: An incoming radio wave is received by array antenna elements which constitute an array antenna, and the correlation between the received data of some array antenna elements is calculated to form a correlation matrix which is not affected by the additive noise at each antenna element. Then a noise subspace is obtained from the correlation matrix by a simple linear operation based on the partition of an array response matrix and is used to estimate the direction of signal (i.e., radio wave) impinging on the array antenna. Because the evaluation of all correlations between the array data received by array antenna elements is not needed, and the eigendecomposition process is avoided, the computational load of the proposed direction estimation technique is reduced, and the noise insensitivity is improved.
