Our cell phones have been almost useless this past year. Our home is quite remote, so it's no great surprise - yet the degraded signal is a problem. Both calls and texts have been missed, and some text replies arrive a day too late to be of much value.
We recently picked up a signal booster, in our case a WeBoost 3G device for residential use. First tests were not great, but eventually I rigged up a test-spot with a consistently decent signal. Today I crawled under the house and rerouted a coaxial cable that once went to a satellite dish. I pulled it to the other side of the house where cell towers are most prevalent, and mounted the antenna high on the side of our home. Once the inside antenna was set up, both our signals was pretty much at maximum strength!
So we have improved from a home where two indoor spots gave us occasional signals to excellent reception in several rooms and our deck as well. Much better!
