Abstract: A fleet of high altitude platforms (HAPs) arranged to provide information services to a service area, each SHHAP comprising at least one phased array antenna and in communication with a telecommunications backhaul system, the service area comprising at least 100,000 items of user equipment (UE), and wherein the service area comprises a non-uniform data requirement distribution, comprising areas of both higher and lower data rate requirements, and wherein the SHHAPs are positioned with a non-uniform spacing such that the SHHAPs are positioned closer together over areas of higher data rate requirements than over areas of lower data rate requirements.

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.
