Nokia makes holographic call over 5G

08 December 2021

Nokia and CityFibre, a digital infrastructure provider, successfully tested a series of simulations over a 5G network including a holographic call.

The company’s established a testbed at the University of Glasgow with three 5G sites backhauled to the core and using 25G passive optic network (PON) to support 5G transport. The fiber runs XGS-PON to carry office traffic, thereby demonstrating co-existence of multiple wavelengths on the PON.

The University of Glasgow is using the 5G testbed to explore business cases for enterprises to exploit and adopt 5G use cases. The test of simulations included the teleoperation of a robotic arm and 6K video streaming over the 5G network.

PON is designed to deliver broadband internet access to a home or office through optical fiber cabling and signals from an internet service provider to the end user. 25G PON is a new standard that expands bandwidth available for 5G signals to get to the home or office.

Nokia’s 25G PON technology includes Lightspan and ISAM access nodes and runs on Quillion-based multi-PON line cards and fiber modems. Depending on which optics are chosen, 25G PON supports symmetrical bitrates of 25 Gb/s in downstream and 25G in upstream and asymmetrical bitrates of 25/10.

The Quillion chipset from Nokia is designed to work with PON technology. The chipset powers Nokia’s 16 port multi-PON line card, which supports both GPON and NG-PON on each port.

"Backhaul connectivity is the real backbone of 5G networks and could be a bottleneck for achieving high end-to-end performance if not well designed to meet demands,” said Muhammad Imran, professor of communications and director of sensing and imaging at University of Glasgow. “In partnership with Nokia and CityFibre, we have demonstrated on our 5G testbed how Nokia’s next-generation 25G PON transport solution can improve 5G user experience by supporting 3D telepresence and remote robotic control use cases.”
