CubeSat-Based 5G Cloud Radio Access Network: A novel paradigm for on-demand anytime-anywhere connectivity

Abstract:

5G networks are expected to become the main infrastructure for security verticals such as disaster relief, humanitarian aid, and governmental and defense communications. In the case of defense services, especially, there are complex areas where coverage and connectivity are not reliable or are completely absent. Thus, the deployment of drones as mobile base stations (BSs) also needs a system designed for reliable backhaul based on satellites. However, a baseband unit (BBU) [devoted to baseband signal processing at the radio access network (RAN)] on drones is not a flexible solution and may require great power supply and processing capabilities, which a drone can hardly host. The work we discuss here studies and designs a cloud RAN system based on mobile BSs and CubeSats, where BBUs are virtualized on low-cost satellites. In particular, the work takes advantage of a split of virtual BBUs to virtualize upper layers on CubeSats, while guaranteeing the satisfaction of technical requirements.
