Introduction

The strategic cooperation of Budapest University of Technology and Economics (BME) and Nokia Labs Hungary was initiated in 2020 establishing the BME - NOKIA 5G Research & Innovation Network. BME’s 5G experimental network is suitable for the latest radio technology research and the development, and testing of 5G applications and services. Based on Nokia’s easily scalable, private 5G platform, the network supervision is entirely controlled by the university. With the 5G test network, BME is the center of 5G R&D in the academic sector in Hungary and ready to collaborate with national and international enterprises engaged in telecommunications and development of 5G applications. Areas of research and application focus on virtual/augmented/mixed reality (VR/AR/MR), the Artificial Intelligence (AI), a telepresence, the Internet of Drones, the Industry 4.0, the IoT, the remote medical diagnostics and telemedicina állnak.

What is 5G technology?

The 5G technology is the most advanced, fifth generation mobile telecommunication technology. Besides the radical improvement of the capabilities of the mobile services in many sectors – vehicle industry, transportation, manufacturing, agriculture, medical services, energy sector, commerce, media and entertainment businesses - 5G technology enables the development of new, innovative and in many cases, disruptive services and business models.

Benefits of 5G Technology

Why 5G technology is necessary?

Due to the massive increase of mobile subscriptions and the demand for broadband services, the introduction of the 5th generation mobile telecommunication technology has become necessary. In 2015 the number of mobile subscriptions already exceeded the world population, and 2/3 of the mobile broadband services are mobile broadband internet subscriptions. Without 5G technology, the quality of mobile internet services would decline limiting the digital transformation.

Benefits of 5G technology

The performance of 5G technology for broadband cellular network significantly exceeds the capabilities of the previous mobile generation (4G). Besides providing significantly higher bandwidth and lower latency, 5G technology was designed to meet the high demands of industrial applications. Therefore, in addition to offering better user experience for individuals, 5G is also expected to significantly boost economic output. 5G technology will expectedly create an innovation wave and substantially affecting the competitiveness and technological development of the world’s regions and individual countries.

6G technology

5G technology has just started recently, but 6G is already in the spotlight of research, and in some developed countries 6G R&D programs have been already initiated. The most significant one is the Finnish 6G Flagship RD program.
The 6G Flagship program is a national R&D program of Finland, coordinated by the Oulu University collaborating with Nokia. The EU is also preparing for 6G technology and in the Horizon Europe R&D program - like the H2020 5G PPP initiative – launched the „Smart Networks and Services” (SNS) European Partnership Programme in 2022 with 900 million Euro funding.
In order to increase the competitiveness of the Hungarian economy, it is of high importance to establish the national 6G ecosystem and foster the connection of the Hungarian R&D institutions and innovative companies to the global and European 6G R&D programs.

Demos

Videoconference on 5G network

Peter Ekler – David Sik – David Deak – Sandor Dilong

The demo presents video streaming technology on 5G network. Within the demo a multiplayer video system is demonstrated, with multiple clients joining simultaneously to the videoconference, without compromising the quality and speed of the video transmission. Over 5G network the solution provides significantly better video quality compared to the previous mobile networks. The demo supports the creation of multiple rooms, so the participants can join any of them, and video calls are displayed in the form of a grid, so all participants can appear on the same screen.

Car tracking and convoy functions on 5G

Peter Ekler – David Sik – Balazs Radetzky – Norbert Urban

When using and tracking a vehicle, the quality of the network and the lowest possible delay are particularly important, since this is the only way to realize real-time tracking and any service based on it. In the demo, a car tracking system was developed supporting convoy functions as well. The demo shows how accurately the vehicles can share data and position in the case of a 5G network, as well as how accurately the distance between the cars can be maintained. Besides, the information flow is also presented in the demo. In case the first vehicle detects an obstacle on the road, it can be demonstrated how quickly and accurately it can notify the cars behind it in the convoy using 5G network.

Mixed reality and virtual 3D ping-pong on 5G network

Peter Ekler – David Sik – Flora Petrok – Peter Orosz – Domoks Kiss – Mate Rezsek

The aim of the first game is that how accurate a complex 3D game can be implemented on a 5G network. The demo shows a classical ping- pong game that is implemented such a way that on the screen a ping pong table with rackets are seen in 3D and the rackets are represented by 5G smart phones held in real hands. The phones with their sensors inside, function as rackets and send their position via 5G to a central server on real time, so that the position and location of the rackets change in real time on the playing field. The demo clearly illustrates, this game can work in real time via 5G, while the game becomes unenjoyable if you use previous mobile technologies. In the other game, two players can play ping- pong where the table, the rackets, and the ball exist only virtually. The players wear VR headsets, which have stereo cameras, so players can see their surroundings as well. The table, the rackets and the ball only seen in the VR headsets. The players movements are localized with the VR headsets and synchronized on the 5G network so that both players can see each other’s rackets and the movements of the ball in real time.

UAV video transfer via 5G network

Laszlo Blazovics – Marton Gotzy

The aim of the demo is to use a drone flying outdoors to demonstrate the capabilities of 5G-based network communication, primarily low latency. During the demonstration, the high-definition camera attached to the drone transmits a continuous video stream to a ground unit, which it also monitors through the camera connected to it. Both the ground and aerial video streams are shown and watched simultaneously.

Immersive Remote Driving Distance Test: Hajdúszoboszló-Budapest (176 km)

Domokos Kiss

We have a model car in our lab (BME Q building, Budapest) while our colleague is driving it from an exhibition in Hajdúszoboszló (distance by air is 176 km). The remote driving station is connected via 4G/5G mobile network. A 3 DOF movable camera is mounted on the car; its orientation is synchronized with the operator's head movement. The head orientation, steering, and throttle commands are streamed from the remote station to the vehicle, while the live video stream of the onboard camera is streamed back. The experienced E2E latency is almost neglectable, resulting in a comfortable remote driving experience.

BME 5G Laboratory

As part of the BME – Nokia 5G Research and Innovation Network, a 5G Laboratory was established in the room B236, Building Q to provide space for 5G use case developments, demonstrations, teaching and laboratory activities, and 5G innovations. The indoor 5G services are available in the 5G Laboratory and also in the adjacent corridors and experimental labs to support R&D, teaching and experimental activities of the students and the researchers. Using test SIM cards provided by Vodafone, besides to the indoor 5G network, the researchers can reach outdoor commercial mobile services as well.
