Everything is fitted with electronics these days. If you can house a router that’s up and functional, you can get wifi anywhere. Same concept of having Wi-Fi in your car or being out and you use someone’s phone hotspot for internet; you can move around, you just connect to Wi-Fi and stay within range.
