Where Does Automotive Network Data Come From?
2 Answers
Automotive network data refers to the data generated within a vehicle's operating system when equipped with a 4G multi-functional infotainment system or a 4G OBD dongle. The principle is similar to that of a mobile phone SIM card. Different manufacturers offer various preferential policies for connected car services as follows: 1. Roewe RX5: Apart from basic services (such as navigation, real-time traffic updates, and remote vehicle control) and basic data allowance, additional services like audio packages and entertainment packages require participation in promotional activities in the following year to have a chance of obtaining them for free. If no activities are participated in and these services are still desired in the following year, additional fees for the data usage will be incurred. 2. Changan CS95: The policy for Changan CS95 is quite similar, but more straightforward compared to Roewe RX5. It directly divides the data allowance into basic and entertainment categories. Basic function data is free for life, while entertainment functions come with a 3-month complimentary music and radio service plus 600MB of data upon purchase. Any usage beyond this requires additional payment.
As an average car user, I often wonder where the vehicle's internet data comes from. Simply put, it primarily relies on the built-in communication module in the car's system to connect to mobile networks for data. For example, modern cars come with 4G or 5G modems that directly use carrier data for internet access, supporting navigation updates or entertainment features. Additionally, mobile hotspots are quite common—sharing data via Bluetooth or Wi-Fi, eliminating the need for dedicated in-car services. Behind this is the integrated hardware designed by vehicle manufacturers, with some even using satellite assistance to enhance GPS signals. The benefit is convenience, like seamless music streaming on the road, but it's important to watch data limits to avoid overages. Overall, the sources are quite practical and significantly enhance daily driving.
