Where Does the Network for Connected Cars Come From?
2 Answers
Through the integration of wireless communication technology and information platforms, services such as real-time navigation, in-depth voice services, and remote vehicle control are achieved. Here is relevant information: 1. SIM Card: Although both car data and mobile data are used by binding a SIM card, the SIM card for vehicles is specially made and built into the multifunctional car system, making it completely invisible. 2. Cannot Connect to Mobile Hotspot: Using a mobile hotspot to provide internet for the car system is not feasible. The onboard WiFi itself is a mobile platform and can only use data or WiFi established by the operator.
I've been driving for years, and the internet connectivity in cars is quite straightforward. It mainly relies on a built-in communication module in the vehicle, which is like a mini router combined with a mobile SIM card. It can directly connect to the cellular network provided by carriers, such as 4G or 5G. This is called eSIM technology. The advantage is that the car automatically connects to the internet as soon as it starts, so I don’t have to worry about hotspots, and it supports real-time navigation updates and remote locking features. The downside is that you might need to pay a monthly subscription fee for data, similar to a mobile phone plan. I’ve seen many new cars equipped with this, and the setup is just a few clicks on the car’s display. Additionally, it can also act as a WiFi hotspot to share with passenger devices, like tablets or laptops. Signal strength varies by location—stable in urban areas but may lag in remote regions. When setting it up, be mindful of security and avoid enabling public sharing mode. Overall, this method is efficient and stable, truly making the car smart.
