There r more than few DTHome providers, but now they have switched via broadband internet
This broadband internet method is 100% safe, because it's signals does NOT depend on weather,broken cables,or very heavy rain.
Internet signals are stables,depending on yr network providers
In the South Pacific ,signals via cables are the best ,mbps is over 90
ADSL 2+ is 7-25 Mbps
ADSL 1 telephone line internet is below 4mbps
Now days I have read that mobile, iPads tablets can excess internet wifi signals within
A home of about 20 metres.but beyond 20metres, u must use wifi repeaters in each room
So the internet signals r upgraded as they gies along the line to another room
In the South Pacific, v use the home power supply power point to transmit
Wifi signals to another rooms.
