We have a holiday house in the mountains in Burgundy (France). Every summer, when we came there, we felt cut off from the rest of the world, as there was no signal in the house. When we needed to make a call or to connect to the Internet, we had to go outside and look for mobile connection for hours. This summer we finally have decided to end up with the poor mobile signal reception and ordered a signal booster NS-150 at MyAmplifiers which was meant to boost gsm and 3G signal.
Once the booster received, we proceeded to its installation which resulted to be much easier than we expected. Before installing the receiving antenna, we used the Cell Info mobile application to determine which of the available masts in the area gave the best signal of our provider. As a rule there are several masts to choose from and the app gives you all the data you need plus a clear indication of the direction in which to point the receiver antenna. In our case we put the antenna high up in the loft, so we did the app signal test twice, on the ground and six meters up in the loft. This resulted in two masts in almost opposite directions being the best candidates. So, once we had the antenna put up, we turned it first in the direction of one, then the other of the two and checked signal strength as emitted by the amplifier in the rooms below before fixing the antenna towards the strongest signal of the two.
We now have a steady signal strong enough for uninterrupted phone calls and internet use, still subject to light variations in strength, but far better than before. In an old house with thick walls like ours, it pays to position the amplifier centrally, for instance in a hall, and at door height, so as to give best reception in most rooms.
