Augmented Reality (AR) is a concept and a set of technologies for merging of real and virtual elements to produce new visualizations – typically a video – where physical and digital objects co-exist and interact in real time. Most AR applications support real-time interaction with content (AR scene with virtual...
Over the last few years, we watched head-worn virtual and augmented reality devices move from research laboratories to store shelves as the newest platform enabling novel virtual experiences. The big promise of emerging mixed reality (MR) technology is a far deeper immersion into imaginary worlds than is possible with the...

? Today?s C-RAN mobile transport network will not scale to
support additional spectrum and antennas
? Separated fronthaul and backhaul management adds
complexity and cost
? C-RAN functional splits are fixed and static
? An integrated fronthaul/backhaul (Crosshaul) will support
diverse 5G traffic types
? Unified management built on SDN frameworks
? Wireless and wired transport for dense network edge
connections, with path diversity for high reliability

Testbed, hosted by Fraunhofer HHI ? under the 5G
Crosshaul project
? 3 EdgeLink mmW Nodes ? outdoor installation on
buildings within the Fraunhofer and Berlin Technical
University campuses:
? Ranging from 95 to 185 meters distances
? 1 GW + 2 non-GW Nodes
? Multiplexing of Fronthaul and Backhaul traffic over
