Introducing a communication solution that supports 5G V2X sidelink communication standards
Providing APIs required for transmitting and receiving 5G V2X application service data

Etiforce successfully completed the world's first 5G-V2X sidelink sensor data sharing demonstration.

Etiforce held a demonstration of its 5G-V2X platform SIRIUS (hereinafter referred to as SIRIUS) and unveiled three demos at the Pangyo Gyeonggi Startup Campus on the 31st of last month.

Vice President Lee Kang-min explained, “Sirius is a communication solution and communication equipment that supports the 5G V2X sidelink communication standard,” and “It is a platform that can implement and demonstrate the 5G V2X application services and use cases that customers ultimately want.”

Vice President Lee Kang-min explained Sirius, who could be said to be the main character of the event.

He said, “If you want to provide a service using 5G V2X, you need to send data to verify and implement the service,” and “At this time, a communication platform that can send and receive service data is absolutely necessary, and Sirius performs this function.”

In addition, Etiphos provides a customer-friendly API required to send and receive application service data through Sirius, allowing for easy integration.

EDM (ETTIFOS Diagnostic Monitor) is Etifos' own softwareIt is a Windows-based software tool as a wearable product. It can monitor and analyze the functions of the 5G V2X sidelink modem and protocol stack operating within Sirius in real time. It is a solution that allows customers to optimize services and analyze and verify quality using Sirius and EDM.

The three demos demonstrated on this day are: △ A demo of exchanging 4K video footage via Sirius equipment using the 5G V2X protocol, △ A demo of exchanging lidar data via Sirius using the 5G V2X protocol, and △ A demo showing the communication performance of 5G V2X.

▲ Demo of transmitting and receiving 4K video footage using 5G V2X protocol through Sirius equipment

The 4K video data sharing demo showed live video data of 3840 x 2160 pixels in size from a webcam shooting the inside of the event venue encoded into MPEG-2 TS and then transmitted using the 5G V2X protocol using Sirius equipment. The demo was prepared with a speed of 55 Mbps, modulation of 64 QAM, bandwidth of 20 MHz, numerology of 1, and SCS of 30 kHz. They demonstrated object recognition using an object recognition algorithm called Yolo using data transmitted via 5G NR V2X.

▲ Demo of exchanging lidar data via Sirius using 5G V2X protocol

The lidar data demo was configured to play back pre-recorded lidar data. The lidar data was provided by Chungbuk National University AVLAB. Velodyne lidar 16-channel data was converted to a format called PointCloud2 and the converted data was transmitted using the 5G sidelink protocol. This was received and the actual lidar image was visualized and displayed. Looking at the parameters of the 5G V2X communication section in this demo, the speed is 55 Mbps, the modulation is 64 QAM, the bandwidth is 20 MHz, the SCS is 15 kHz, and the numerology is 0. The biggest significance of this demo is that even autonomous vehicles that are not equipped with lidar can receive data from the infrastructure or lidar installed on vehicles that are equipped with lidar and apply the data to autonomous driving.

▲ Demo showing the performance of 5G V2X communication

A demo showing the communication performance of 5G V2X showed that 90Mbps can be achieved when 256QAM modulation is applied in 20MHz Bandwidth. The latency is only 4.5ms. This is a significant increase over the transmission capacity that WAVE, LTE V2X can transmit at 27Mbps in 10MHz.

“We will present different functions in June and November 2023,” said Hong Seung-soo, Etiforce’s managing director. “In June, we will present 5G Rel. “Groupcast, a newly defined connection method, will be released in 16, and unicast will be released in November,” he said.

Meanwhile, at the event that day, experts continued to make presentations that V2X technology is essential for autonomous driving in urban areas.

Lim Ki-taek, head of the Mobility Platform Research Center at the Korea Institute of Electronics and Technology (KEIT), said, “V2X communication technology must be applied for autonomous driving at Level 4 or higher,” adding, “The only technology that can transmit sensors, surrounding vehicles, and infrastructure information in real time to cars driving at high speeds is V2X technology.”

Professor Jeong Gu-min of Kookmin University said, “V2X is essential for autonomous driving in urban areas because it can overcome dilemma zones, such as where it is difficult for drivers to decide whether to proceed through an intersection when the signal turns yellow, and provide objective information and judgment in situations that are difficult for people to make intuitive judgments.”
