Autonomous or not, modern vehicles carry several different types of radio equipment on board for fulfilling regulations to support advanced driver assistance systems, but also for convenience applications. Trucks have been connected to public networks (e.g., 4G and 5G) for more than two decades, whereas cars and vans have just recently started to be connected. The “mobile phone” installed in vehicles can be found under several names but the most common is probably telematics gateway.
In a previous “Connected and Automated Vehicles” column [IEEE Veh. Technol. Mag., vol. 18, no. 3, pp. 120–122, Sep. 2023], I elaborated on the costly subscriptions that automotive manufacturers have experienced in the past, leading to onboard applications that use public networks being designed to transfer only the indispensable numbers of data between a vehicle and a back office (or cloud, as it is called today). The telematics gateway also includes a global navigation satellite systems (GNSS) receiver for enabling applications where the position of the vehicle is important.
Mirroring smartphones to the dashboard is a capability that many users expect to be present in modern vehicles today. This mirroring uses either Wi-Fi or Bluetooth.
Other types of radio equipment are wireless key openers, where ultrawideband (UWB) technology is the preferred solution. This UWB radio is already available in modern smart phones, and suddenly, the car owner’s mobile phone can be used as the door opener of the vehicle. UWB offers several advantages, such as increased security but also efficient key sharing applications.
