Phone as wifi hotspot plus wifi router

The idea is very simple: A high gain wifi antenna and router like Ubiquiti Bullet M2 is mounted on the boat or camper. Its web interface is used for connecting to distant wifis.

A smartphone receives the GSM cellular network and works as a wifi hotspot in tethering mode. When this network is needed, the only thing to do is calling the Bullet’s web interface and switching to the phone’s network.
