Abstract: Disclosed is a communication device and method for estimating a more accurate vertical position or altitude of a communication device using atmospheric pressure measurements. In one embodiment, a first communication device comprises a pressure sensor for measuring local atmospheric pressure at the first communication device and a transceiver for communicating with a second communication device, wherein the transceiver may be operable to receive barometric calibration information for calibrating a local atmospheric pressure measured at the first communication device and/or to transmit the measured local atmospheric pressure to the second communication device. The first communication device may further comprise a processor for estimating an altitude using the measured local atmospheric pressure and received barometric calibration information.

Abstract: A wireless transmitter and receiver are used in a wireless telecommunication system and method including antennas having at least one antenna element with a relatively narrow beamwidth at both the transmitter and receiver for high data rate communication. The antenna element provides beam coverage in both azimuthal and elevational directions, and a processor is operatively connected to the antenna and is capable of determining a suitable communication path with respect to the at least one antenna element and predetermined communications conditions.
