12. WiFi vs. 5G

Why do users prefer WiFi over 4G cellular data?
----

WiFi is free and pretty fast with higher data transfer rate. 4G unlimited data is expensive and bit rate is also lower.

I am not using wireless tablet or iPhone. The only service that I would use is working with laptop connected to 4G network anywhere. However paying both cellular phone and 4G wireless stick is expensive. I am not sure if Bluetooth of a cellular phone could pair with a laptop, then offers 4G Internet to the laptop?

Nokia plans to integrate cellular services to a car's control center? Could they offer [WiFi] Internet to the car by connecting the 4G networks using Bluetooth of the cell phone? Btw, if they could offer WiFi in the car, many in-car passengers would use the services.
