The “Car-Fi” V2X gateway prototype developed by EDI is a network device that provides a data transmission functionality with the option to use up to three different data transmission technologies at the data link level – DSRC (IEEE 802.11p, 5.85–5.925GHz), LTE (4G) and LoRa (IoT protocol, 868MHz).
Such devices are intended for V2X applications on streets and roads – they are installed in vehicles and roadside infrastructure devices (V2X or “vehicle to everything” describes the data exchange between one car and another or between a car and a roadside infrastructure device).
The devices may be used for the following purposes:
The IEEE 802.11p DSRC protocol is currently the de-facto standard for V2X data transmission in the EU, the US and Asia. The C-ITS-G5 set of standards issued by ETSI (European Telecommunications Standards Institute) governing communication between intelligent transport systems (ITS) on roads and streets at the data connection level is based on the IEEE 802.11p DSRC protocol among others. It means that roadside devices equipped with this technology could also be used as a platform for the development of future V2X application scenarios, that are already supported by large car manufacturers and will be compatible with applications in other EU countries.
