This paper discusses the importance of reconfiguring the front and backhaul of networks for SDN in 5G networks, and the feasibility of using phased array antennas instead of reflector antennas. It analyzes challenging requirements such as energy consumption and compliance with regulatory radiation masks, and proposes possible solutions and future research directions.
Software Defined Network is one of the key enabling technologies for the upcoming 5G networks. Both the fronthaul and the backhaul of the network must be reconfigurable for SDN to work properly. Phased Array Antennas could add to the backhaul/fronthaul wireless equipment beamsteering capabilities to make it reconfigurable. This paper summarizes feasibility considerations resulting from the desire of replacing the current reflector antenna with phased arrays in the backhaul segment. Energy consumption and compliance with regulatory radiation masks are analyzed and found to represent challenging requirements. Several techniques are also identified as possible solutions to comply with such stringent demands and future research steps are described.
