How Does Automotive Network Data Traffic Work?

[DiLorenzo]

Automotive network data traffic refers to the data usage within a vehicle's operating system, which is enabled by installing a 4G multi-functional vehicle head unit or a 4G OBD dongle. The principle is similar to that of a mobile phone SIM card. Different manufacturers offer various promotional policies for connected car services, as outlined below: 1. Roewe RX5: Apart from basic services (such as navigation, real-time traffic updates, remote vehicle control, etc.) and basic data allowance, additional services like music packages and entertainment packages require participation in promotional activities in the following year to potentially receive them for free. If no activities are participated in and these services are still desired, the corresponding data usage fees must be paid separately. 2. Changan CS95: Changan CS95's policy is quite similar, but more straightforward compared to the Roewe RX5. It divides the data allowance into basic and entertainment categories. Basic function data is free for life, while entertainment functions come with a 3-month free trial of music, radio, and 600MB of data upon vehicle purchase. Any usage beyond this will require additional payment.

I think most of the car's internet data comes through the built-in cellular module. When I listen to music or use real-time navigation while driving, it functions like a mini phone with a SIM card automatically connecting to the carrier network, consuming data rapidly. I often share my phone's Wi-Fi hotspot with the car to save money and control data usage. Car manufacturers usually provide some basic data allowance, but exceeding it may incur charges, so I always check the settings before trips to avoid waste. Interestingly, this data isn't just for entertainment—it also enables software updates and emergency calls, making driving safer and smarter. With future upgrades to 5G, response times will be faster, but I also need to be mindful of privacy to prevent sensitive data leaks. Overall, managing these connectivity options can significantly enhance the daily driving experience.

I believe the source of automotive network connectivity relies on hardware mechanisms. Simply put, it's the vehicle's built-in modem connecting to mobile networks and converting signals into data transmission. When I activate the vehicle system, the data is used for real-time maps or remote control apps. If the SIM card establishes a stable connection with cell towers, it functions reliably. Users can also share mobile hotspot internet with the car for greater flexibility and cost savings. Notably, data throughput depends on network speed (4G or 5G) – faster speeds enable quick movie downloads or game loading, but usage monitoring is essential to avoid overage fees. Leveraging public Wi-Fi for large downloads or selecting appropriate data plans is advisable. Overall, this technology enables vehicle connectivity, and future V2X integration promises smarter, more efficient operations.

Data usage primarily comes from in-car or mobile sharing services. For instance, when I use the connected car app to control the air conditioning or update software, it consumes data by connecting to the cellular network. Automakers typically provide limited free data, and users need to subscribe to a data plan once the limit is exceeded. I recommend choosing a suitable plan to save costs. From a privacy perspective, data transmission is encrypted for security protection.
