Description
Summary:Due to the availability of large contiguous bands in excess of several gigahertz in the millimeter wave spectrum, millimeter wave communications will play a key role in 5G - the next generation mobile networks. The applicability of simple air interfaces without the need for complex techniques for optimized spectrum utilization make mmW carrier frequencies a preferred solution to cope with the huge traffic demand. The smaller wavelength enables usage of large antenna arrays supporting strong beamforming gains that compensate for the higher path loss at mmW frequencies and thus allow for a deployment of cellular access networks in dense urban outdoor scenarios. This work focuses on a real-time software demo of a 5G mmW network in a Chicago model operating at 73 GHz. The propagation effects and implemented channel model is based on measurements performed at 73 GHz. The 5G demo illustrates the dynamic cell re-routing caused by terminal and scatterer mobility in a 3D view of the dense urban street scenario and computes all relevant key performance indicators derived using a detailed RRM model. The key feature of this 5G mmW demo is the modeling of in-band wireless backhaul techniques to foster realistic deployments of mmW access nodes including inexpensive wireless backhaul links to the egress point(s) within the same band.
