23 AV FOCUS Virtual Reality
display amid the Hermitage’s 18th-century grandeur and employ a mix of virtual reality, haptic technology and robotics, using the 5G test network in the 3500 MHz frequency band that has been supplied by Rostelecom. One demonstration, for example, shows the restoration of a work of art – a statue, in this case – using a remote-controlled robotic arm. The arm, gripping a delicate restorer’s brush, is operated remotely. It serves to illustrate how 5G’s low bit rate, low-latency characteristics could enable restoration experts to conduct art restoration work with a high degree of accuracy from anywhere in the world. It is a window into a future where an expert in London might be able to restore a painting that is in Sydney. On the other hand, another use case demonstrates the remote learning possibilities for 5G. In this one, an art master uses a remote-controlled robotic arm to show students precision techniques for restoring works of art. Both demonstrations use a 4K video stream that is transmitted to VR glasses. This creates the effect of real presence for both the teacher and the students.

Petersburg gives visitors a glimpse into the future. The exhibition consists of a 5G trial zone, which showcases innovative applications that are combined with immersive technologies and run on 5G networks. People often regard 5G networks as a cure-all for every type of technological woe – like the hypothetical cold fusion of nuclear reaction – that will bring about an IOT (Internet of things) paradise. However, it’s hard to deny that 5G, when it’s rolled out widely, is going to be a game changer for everything, from latency to reliability and from battery life to data access. When exactly 5G will arrive is a moving target, and will vary from country to country, or region to region within countries. But it will come. And the 5G trial zone at the Hermitage Museum offers a snapshot of what might be possible in the future. Opened in May 2018 and running until the end of the year, the 5G trial zone is sponsored by Ericsson and Russian digital services provider, Rostelecom. The 5G use cases, open to the public, are put on
