A few days ago, Ericsson, South Korea's SK Telecom and BMW successfully completed the leading 5G field mobile test and completed multi-vehicle 5G test. A 5G test network was deployed on the BMW car test track in Yeongjong Island, South Korea. Together with SK Telecom, Ericsson deployed network slicing and 5G wireless network infrastructure, and the test network covered a complete track of the BMW Driving Center. The trial showed that 5G will be able to support V2X services, and V2X requires low latency and high consistency for two-way communication.
Alex Jinsung Choi, chief technology officer and head of R&D at SK Telecom, said: "5G not only provides faster data transfer speeds. It will create more powerful services and bring unprecedented value to users. Today's 5G car networking technology The demonstration is the first step towards fully automated driving in the next 5G era."
The test environment is based on the Ericsson 5G field test network, which includes multiple wireless transmission points on the 28 GHz band to cover the entire test track and the UEs installed in each car. Tests show that throughput is always stable at the Gbps level with a latency of only a few milliseconds. When the speed exceeds 100km/h, an uninterrupted connection is achieved by using beam tracking and beam transmission at different transmission points. Based on Ericsson's wireless access network and core network system solutions, the tested 5G performance enables multiple vehicle networking use cases such as augmented reality and virtual reality, obstacle control and inter-vehicle communication.
Thomas Norén, Head of Networking Products at Ericsson, said: "Ericsson is working with the world's leading operators and ecosystem partners to drive 5G – including today's quasi-5G standard field testing and standardization activities with global standards organizations and industry partners. Etc. Through this test, 5G technology and commercialization go further, especially for vehicle networking applications."
This test enabled a number of new 5G important features, including multi-site, multiple transmission points, MU-MIMO, and running multiple terminals in the millimeter-wave band. The test demonstrates beam tracking and beam movement between different 5G access points in high-speed motion.
Ericsson is supporting a number of cooperation agreements with global operators through industry-leading 5G test systems, enabling operators to continuously measure new applications through the corresponding 5G test environment.
