So I did some testing on the Wilson Electronics cellular booster yesterday... Nothing too remote, but I went to a spot I had no service once. The corner of S2 and HWY 79 headed towards Borrego. I sat here one night waiting for Barlow to go to the Borrego Fest. Instead of bars, I had "No Service"... So with the booster powered off, I drove up to the spot, and sure enough, no service, I turned on the booster, and it quickly built its way up to 5 bars (full) and 3G service. I was able to browse the web quickly, and send and receive texts.
Now, with the Model 801201, I've seen people complain that the internal antenna has to be close. So we tested this too.. My wife had her cellphone in the passenger seat, mine was in it's mount on the dash with the internal antenna very close to the mount (very near where I intend to mount it permanently). If she kept her phone away greater than 18" inches from the antenna, it didn't provide any boost in signal for her. You have to have your phone close.
This isn't a problem for me, since I put the phone in it's mount, and I have the hotspot feature, so the internet enabled devices will catch wi-fi through my phone.
Overall, I'm pleased with how well it worked in a semi-remote location. Driving on out to the place I noticed my phone rarely had less than 5 bars... which that drive can be spotty on service (from San Diego to Lake Henshaw)..
