The repeater will allow you to greatly expand its scope. Used successfully for the phone captures up inside a lodge in aliminium frame located 30 meters from the base. The base being located on the other side a U-shaped part or is the téphonique arrival and the internet box. The wave had to be spread by being hindered by thick walls. This repeater placed on the other side of the U solved the problem receiving handset away from the base. Only defect that obviously its price is more expensive than many phones! A buy only if you do not have a choice. Good shopping on Amazon.
