The Cost-Effective Benefits of OTA Testing for Automakers in 2024

The automotive industry is constantly evolving, requiring automakers to stay on top of the latest technology and trends to remain competitive. One of these trends is more connected vehicles, i.e. autonomous driving. An important part of ensuring reliable connectivity of these connected vehicles is Over-the-Air (OTA) testing. By running OTA tests regularly, automakers can identify and fix issues before they become major problems. This helps to reduce the cost of production, speed up time to market and improve the overall quality of their vehicles. 

What is OTA testing?
Over-the-air (OTA) testing is a crucial methodology employed to evaluate the performance and reliability of wireless devices, particularly those integrated with embedded antennas. This technique simulates real-world scenarios to assess the device’s ability to transmit and receive signals effectively under various conditions. OTA testing plays a pivotal role in ensuring the seamless operation of wireless devices, particularly in complex environments like vehicles.

Benefits of OTA testing
OTA testing can be done at different instances during product development, which allows automakers to identify and fix issues before they become major problems. This helps reduce production costs, as automakers can avoid costly repairs and recalls.

The OTA testing helps to ensure that the vehicles have reliable connectivity, which is crucial for customer satisfaction and loyalty. In a McKinsey & Co report, they highlight that 37% of car consumers are willing to change car brand due to bad connectivity, which indicate the importance of this topic.

OTA testing also goes beyond basic signal transmission and reception; it also simulates various real-world conditions that can impact wireless communication. These conditions may include movement, interference, and changes in environmental factors. This ensures that the DUT can operate reliably in the challenging environments it will encounter in the real world.

Conclusion
OTA testing is not merely a testing process; it is a strategic investment that automakers cannot afford to ignore. By embracing regular OTA testing at their own site, automakers can get a multitude of benefits, including reduced costs, accelerated time to market, enhanced vehicle performance, improved connectivity and safety, and the ability to embrace technological advancements. Therefore, OTA testing will undoubtedly play an increasingly pivotal role for car manufacturers who aim to reach their customers’ expectations in connectivity for 2024 and beyond.

And since our society becomes more connected every day, the expectations for vehicles will only get higher each year. Automakers responsibility is to make sure vehicles are tested properly during the whole product development, to maintain safety and reliability. process top priority. By performing these OTA tests regularly, with for example RanLOS test system, automakers can not only reduce the cost of production and improve the overall quality of their vehicles, but they can also contribute to a safer and better connected society. 

Data and Sources

• In a survey by McKinsey & Company, 37% of car consumers reported that they would be willing to switch car brands due to bad connectivity.
• According to a report by Statista, the global market for OTA testing is expected to reach $10 billion by 2027.
