Our guide to navigate 5G and V2X airwaves

In our explanatory videos, we show how different types of connections can work together in the V2X ecosystem to make traffic safe and efficient.

A diverse infrastructure operates along the roads which combines mobile networks with vehicle-to-everything (V2X) roadside units and other radio technologies to offer traffic participants safety and efficiency solutions.

We made a short video about network technologies used in Intelligent Transport Systems, including long-range 5G services for general infotainment services and short-range V2X messaging for almost real time information sharing that is essential for life saving services. 

Everyone is talking about 5G and V2X

Cars use the same 4G or 5G mobile network for long-range connections as mobile phones. And when it comes to mobiles, it’s worth keeping in mind that these devices have been seen as a distraction for years, it’s not necessarily good to build road safety on that.


While 4G and 5G works well in distributing general weather news and traffic information, short-range V2X messages are essential for safety. These low latency V2X messages are transmitted in the 5.9 GHz band directly between V2X roadside and on-board units.

However, the two V2X and 5G do not have to be treated completely separately. An interesting connection between the V2X and the 5G infrastructure is that V2X roadside devices may give a helping hand for 5G mobile network operators, providing a space for 5G radio equipment.

The more information sensors and networks provide, the better decisions we can make

This topic is huge. If you want to dive deep into the details, as Laszlo Virag, our CTO did in a recent webinar hosted by ITS America, take a look at the recording below. Laszlo shows us the present and future evolution of 3GPP mobile network standards, how mobile phones could fail to work as a pedestrian safety gear in a critical traffic situations, and he talks about how data fusion, the combination of 5G, V2X and different sensors can be crucial in road safety.

Commsignia’s devices use pieces of information coming from navigation services like Waze, TomTom, Here, Google Maps, and other pieces from short-range messages delivering information from roadside sensors, cameras and V2X-equipped vehicles. All we need to do is to combine this data in a smart way to provide accurate and timely warnings to traffic participants.
