5G E-band Backhaul System Measurements in Urban Street-Level Scenarios

More than half of the mobile backhaul connections are wireless and huge capacity promise of mmW bands is compelling to cope with the increasing data capacity for future 5G system. We reported a backhaul E-band measurement campaign focusing on radio system measurements with the demonstrator developed in the project. The evaluations include the throughput measurement with different modulation coding scheme and hop length in LOS scenario and the link performance in the light obstructed LOS. It is reported that 1 Gbit/s could be supported up to 300 m, and a reliable transmission was possible up to 400 m at the minimum throughput. The accuracy of beam alignment has been evaluated and it could be improved with the help of electrical beam switching function.
