1. A method for polarization aligned transmission towards a receiver device, the method being performed by a mobile wireless device, the mobile wireless device comprising an antenna array, the method comprising:
obtaining, based on analysis of an image of the receiver device as captured by an image capturing unit, information pertaining to an orientation of an antenna of the receiver device towards which a signal is to be transmitted; and
transmitting the signal from the antenna array towards the receiver device using a wave, the wave having its polarization aligned, based on the orientation of the receiver device, with the antenna of the receiver device, the signal transmitted in a beamformed pencil beam by beamforming weights being applied to antenna elements of the antenna array, and the beamforming weights determined by orientation and direction of the antenna array relative to the orientation and direction of the antenna of the receiver device and relative distance between the mobile wireless device and the receiver device.
