Abstract: A method for maintaining a connection of mobile user equipment to a core network, and a communication network are disclosed. The method comprises the steps of providing a multi-channel communication link between a user equipment at a first location and a plurality of aerial vehicles, determining that the user equipment is moving whereby a loss of connectivity via the multi-channel communication link may occur, and subsequently, via a handover step, transferring communication between the user equipment and a core network from communication via the multi-channel communication link to communication via a single channel communication link provided by a respective aerial vehicle.

Abstract: The use of phased array antennas in ground based or low altitude user equipment linked to high altitude aerial platforms also utilizing sparse phased-array antennas (uniform and non-uniform), which enables the delivery of information services, including telecommunications, earth observation, astronomical and positioning services with higher data rates, lower weight, power consumption and sidelobe levels than for other antenna arrangements.
