How many times have you awoken in the morning to find that your smartphone has been updated? These updates can completely change the features of your device, making it more comfortable and convenient to use. This is all made possible by over-the-air transmission (OTA).
The ability to download applications, services, and configurations over a cellular or wireless network* is referred to as 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 on the target device, subject to the owners’ approval. The smartphone is one of the most common devices to use this technology, but it has become an integral technology across many IT industries, including the automotive market.
OTA is found in in-vehicle infotainment (IVI) systems, where it provides various updates on the user interface (UI) for navigation systems, digital cockpit functions, acceleration speed, and driving assistance. Its function, however, is not limited to basic software updates.
When the Automated Driving System is activated, OTA is critical (ADS). To function properly, vehicles on the road must smoothly exchange key data, such as driving speed, direction change, and sudden response to emergency situations, and all autonomous vehicles and traffic systems must share the most recent version of software to communicate efficiently with one another. OTA meets these requirements by establishing a network, determining the location of the vehicle, and downloading the most recent software that complies with each country’s regulations.
Another important feature of OTA is that it collects big data, which aids in the development of better models and solutions for the future. A wide range of data on time-sensitive technical issues is gathered in real-time, including problems caused by autonomous vehicles, ensuring the eventual arrival of perfect, safe, and convenient autonomous vehicles.
Manufacturers and developers alike 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 automakers’ rapid evolution from manufacturers to tech companies capable of delivering new and better software globally in a faster and more cost-effective manner via OTA. The convenience and cost-effectiveness provided by OTA are encouraging an increasing number of customers worldwide to purchase automated electric vehicles.
