File Downloads And Software Over the Air Updates For the Automotive Industry

Solution Brief

A constant for automobiles with on board computers, and especially for electric cars, and any user of the many products that are part of daily life, is the periodic need to download software and file updates. From the perspective of auto manufacturers, the ability to update their cars software without having customers bring their vehicles to a dealer for these updates is a huge convenience. Plus, these updates can add new features and functionality as well. Each download is a touchpoint opportunity with their customers, who have high expectations for how well this process performs. Provide them with a great download experience and you enhance their desire to remain a customer. But if things go wrong with a download, you will turn them off and risk bad word of mouth. Fortunately, there are download solutions available to solve the challenges unique each download scenario.

Challenges: Continuously Growing Download Sizes

One thing we know for sure is that software file sizes increase with every release as new capabilities and features are added. Over the air updates are primarily driven by electric vehicles, although a few premium model gas cars support this capability. The leader in electric car sales and OTA update capability is Tesla, followed by German, Japanese, Chinese and US auto companies. The update file sizes are typically in the range of 1GB to 2GB, so this update size is not at all challenging for this download solution to support.

 

As a comparison, automotive OTA download sizes are dwarfed by large video games. Many of the big popular games are over 100GB, and a few are much larger. What’s driving the file sizes are the game graphics that get more sophisticated and realistic with each release. The number of players for popular video games ranges from a few hundred thousand into the millions.

 

Adding to the challenge of distributing downloads to a global user base, is ensuring this interaction with your customers lives up to their expectations for a fast and robust experience.

Addressing These Challenges

Top tier Content Delivery Networks (CDNs) are well suited to delivering these massive downloads with their capacity and global reach.
