How many times have you woken up in the morning to find that your smartphone has been updated? These updates can completely change the functionality of your device, making it more comfortable and convenient to use. All of this is made possible by over-the-air transmission (OTA).
The ability to download applications, services and configurations over a cellular or wireless* network is called over-the-air (OTA). When a manufacturer releases a new software or firmware update, it is uploaded to the cloud and made available for download to the target device, subject to owners’ approval. The smartphone is one of the most common devices to use this technology, but it has become an integral technology in many IT industries, including the automotive market.
OTA is found in in-car infotainment systems (IVI), where it provides various updates on the user interface (UI) for navigation systems, digital cockpit functions, throttle speed and help to driving. Its function is not limited to basic software updates, however.
When the automated driving system is activated, the OTA is critical (ADS). To function properly, vehicles on the road must smoothly exchange key data, such as driving speed, change of direction, and sudden response to emergency situations, and all autonomous vehicles and traffic systems must share latest version of software to communicate with each other effectively. . OTA meets these requirements by establishing a network, determining the location of the vehicle and downloading the latest software that complies with the regulations of each country.
Another important feature of OTA is that it collects big data, which helps in the development of better models and solutions for the future. A wide range of data on time-sensitive technical issues is collected in real time, including issues caused by self-driving vehicles, ensuring the eventual arrival of perfect, safe and convenient self-driving vehicles.
Manufacturers and developers are constantly striving to improve OTA and minimize issues caused by unknown variables. The constant modification and evaluation of the core system is what makes this technology more valuable and meaningful.
OTA benefits both manufacturers and customers by saving time, money and effort in deploying new software. Customers no longer need to visit a repair shop for software updates, thanks to the rapid evolution of automakers from manufacturers to technology companies capable of delivering new and better software at scale faster and more cost-effectively via OTA. The convenience and cost-effectiveness offered by OTA is encouraging a growing number of customers around the world to purchase automated electric vehicles.
