I tried to use some European Products and I dont care what Chipset the used but when the Train goes up to 230khp (who is very slow) the Gateways drive insane and find not Network anymore.
The same for a longer Tunnel after that no Signal even my Phone show me a full Bar.
So what I looking for is:
a) Cellphone Voice Call -> VoIP not Analogue Phone Port
b) Stable SW who support the use onboard Trains the have contentious Internet.
c) Disable, Disallow 2G Connection to use only 3G, LTE Connection
d) Fast and relayable connection on fast Trains. There Wifi Connection suck a lot. With my Phone the Connection is more stable and faster. So I want to Stream IP Data over LTE and need a Stable Connection.
I saw about VPN Tunnel. Its possible that the Gateway establish a VPN Connection?
