To highlight its expertise in connected vehicle technology, at last week’s 25th ITS World Congress, Chinese telecommunications giant Huawei Technologies launched the world’s first commercial C-V2X (cellular vehicle-to-everything) roadside unit (RSU) supporting LTE Uu and PC5 concurrence.

Based on 3GPP R14 LTE-V2X technology, Huawei’s RSU is a roadside network device that can support low-latency V2X data broadcasting, enabling intelligent traffic management and automated driving. The technology aims to help road operators, government transportation and public safety departments, industry and operator customers, improve road traffic efficiency and highway safety.

As the world’s first, it successfully supports data exchange over Uu and PC5 interfaces to ensure safe communications. Wired and wireless access modes are used to flexibly connect road facilities, such as traffic signal controllers, facilitating project deployment. Huawei’s RSU also supports the US-based Global Positioning System (GPS) and China’s BeiDou Navigation Satellite System (BDS). Due to the RSU, the latency over PC5 is less than 20ms, and supports 20MHz bandwidth of the 5.9GHz waveband, which is the frequency deployed by most countries for intelligent transportation systems (ITS).
