Реферат: A communications apparatus comprises a power amplifier configured to amplify a signal for transmission, a controllable switch coupled to an output of the power amplifier, an omnidirectional antenna coupled to a first output of the controllable switch, an antenna array coupled to a second output of the controllable switch, the antenna array comprising a plurality of antennas configured to form the signal into a beam of transmitted signals, the beam having a directional bias with respect to a location of the communications apparatus, and a controller. The controller is configured to control the controllable switch to switch a between a first mode of operation of the communications apparatus in which the signal for transmission from the output of the power amplifier is fed to the omnidirectional antenna, and a second mode of operation of the communications apparatus in which the signal from the output of the power amplifier is fed to the antenna array.
