This is also used very much at ships, both at sea and on inland waters. They can not be connectable by fibre optical or copper cable.
The only possible way would be the same as used here in Arnhem with trolley buses. They use 600 Vdc= with 1000 Adc= when accelerating on a two line copper cable 4.5 meter above the streets in the whole city even uphill from 5 to 80 meters above sea level! The north of Arnhem.nl is laying in hills and the south of it is in a low polder Betuwe between the rivers Rhine and Waal. In both sections of this city trolleybuses are traveling even big ones with 3 axles with moves independently i.e. like a harmonica. https://commons.wikimedia.org/wiki/File:Breng_5243,_Arnhem_station.jpg I am not sure if they use that cable for communications too? Many international travel companies come here to see how this works.

The same goes for hobby sailors. But the professional inland skippers with bigger ships all have it, and also many expensive yachts for the happy few (big share holders ;-).

That can be done by intelligent hard- and software as used today in domes. I thougt it costs at least 4000 Euro's to get one, and then even a high monthly fee for the data transport. I.e. much higher that ADSL or Fibre prices, especially when you compare that by the given troughput per MegaByte or time period.
Small inland ships use DVB-T1 and/or DVB-T2 DigiTenne for watching tv, and 3G/4G for mobile InterNet and VoIP. Only the richer skippers with bigger ships have satelite dishes in domes. The same goes for passenger ships.
For today my plan was to sail from Delfzijl to Leer via the Ems in Germany, but at the historical ship of a girlfriend yesterday the engine had stopped because of dirty fuel problems near Groningen, so I have to wait until that is repaired to travel by train and foldable Brompton bike to that ship in Delfzijl ;-(. When sailing I am AFK (= Away From Keyboard) and do not watch tv or InterNet.
Henri.
