New cell phone booster review

What's interesting about these new FCC-approved amplifiers is that they're quite smart. They don't provide excess amplification if it's not needed. Which means, that if you're in a relatively high signal area you may not notice too much change to signal strength when you add the amplifier. With my old Wilson Sleek I used to see ~10-20 dBm of increased signal strength regardless of what it was without the device. That's not the case with these newer devices.
