How the Sure Signal
works
The Sure Signal contains a small 3G
transmitter and receiver, which it uses
to connect with registered 3G phones,
laptops with internal 3G modems,
and USB 3G modem sticks,
rather like a Wi-Fi network does.
It then relays calls, emails and internet
access through your existing broadband
connection.
You will get the best results if you
position your Sure Signal as centrally as
possible, and avoid putting it too close
to metal objects or other transmitters
(like Wi-Fi routers).
