Traveling with a now 10 year old, internet next to staying overnight at some cool places is very, very important !
During our 2019 trip I managed to operate the small WiFi repeater that I normally use for the Parrot Bebop 2 Drone to boost the signal. A s a Wifi repeater creating our own bridged private network around the car. Riding smoothly on the free or occasional paid internet connections that we encounter while traveling with all the connected devices.
Back home I dived into the connectivity puzzle
As boat owners often make use of the harbour Wifi connection when docked or off harbour 3G/4G LTE for online connections. I bumped into the TELTONIKA RUT240 4G LTE ROUTER. It operates on multivoltage, has 3 and 4G as well as WiFi. Can be configured as a private gateway / repeater. Thus fully complying with our needs. For starters it will operate with the standard antennas, but I might create an external antenna from a spare telescopic pole that is not used anymore.
