DJI Mavic Mini RC Transmission

I am new to drones, so if this is a daft question please forgive me.

I have recently bought a MM. Great drone! My ‘issue’ I seem to have is the method of connection from the RC to the drone. I get the bars, like a phone signal with RC next to it, however most of the videos I have viewed online have WiFi style signal. Am I missing something, or doing something wrong? Or is it nothing to be worried about?
Thanks in advance.
