By connecting the 12dB Signal Antenna directly to a telephone system you won't require a landline anymore.
Provide better reception in those rural areas that everyone travels too, yet carriers do not build enough towers there.
Even in areas of poor network coverage, optimal reception can still be achieved by using a directional antenna with higher antenna gain.
All the functions of your telephone system will continue to function (i.e. caller ID display, speed dial etc.)

If the landline connection becomes interrupted (lines become clogged), the 3G network can provide you with an effective backup system
Easy installation and configuration.
