Automotive electronics industry is in constant evolution, making the car always safer, greener and more enjoyable to drive.

Vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communication, collectively referred as V2X, is a wireless technology aimed at increasing road safety and improve traffic management, introducing a new concept of intelligent transport system (ITS), capable to reduce environmental impact.

V2X technology is based on 5.9GHz Dedicated Short Range Communication, a derivative of WiFi specifically defined for fast moving objects. It allows vehicles to communicate their state, such as their position and speed, to surrounding vehicles and infrastructures even in non-line-of-sight condition, such as behind a building or a curve.

Driver awareness of potential dangers on its way, such as crash risk, unsafe overtake, vehicle braking ahead out of line sight, car in blind spot area or road hazard detection, will dramatically improve collision avoidance, and heavily reduce fatalities and injury severity. In addition, the technology will enhance traffic efficiency providing warnings for upcoming traffic congestions, proposing alternative routes and securing an eco-friendly driving, reducing CO2 emission through adaptive cruise control and a smarter transportation management.

Driven by those benefits and the determination to become an key player in this field, ST launched a cooperation with Autotalks for the co-development of a mass-market optimized V2X chipset. Recognized as the V2X chipset market pioneer, Autotalks is bringing in this cooperation their system expertise and know-how of the V2X technology. Leveraging on a robust joint design and ST’s Automotive Quality and Manufacturing machine, Autotalks will release to the market an unique V2X solution. More information @

To deliver a complete high-quality V2X system the co-developed Autotalks V2X Communication processor is combined with ST’s Multi-constellation GNSS receiver, Teseo, that builds a perfect match to ensure a precise positioning accuracy, low latency and a state-of-the-art Dead Reckoning.
