Well done. How about the actual operational needs.
To pick a simple example. Tetra works on the TGV, GSM doesn't


GSM could, GSM is now possible on airliners using cells on the aircraft
linked up to satellite or down to ground stations, and GSM is regularly
used on sea going Ferries using similar systems.

A more practical example is when i was in Hong Kong in 2002 i was using
GSM all over their MTR underground railway.
Obviously if the public have GSM down there, so did the staff and any
emergency services.

Tetra is a badly conceived and applied standard that should never have
existed and only does because of the vast amounts of money and
bureaucracy dedicated to it.

But quite why?..

Dolphin has proved it to be a commercial failure.

Dolphin was never planned properly, never worked as it should have done,
and no one understood it and what it could and couldn't do;!;..
