Verizon wireless updating cell towers
climbing a tree, or standing on a ridge or your roof? You can get a little more signal with a high-gain directional antenna, but not tons.
Plus it has the added benefit of being mounted outside, most likely on your roof.
if you have zero signal the repeater will have zero signal. every phone company has this as a dead zone as well.
normally they are used to provide buildings with "inside coverage" because steel and concrete can kill coverage. one thing i do recommend is to download the latest list of towers in your area. i used to get 0-1 bars, after the update i get 0-3.
They work well, rather or not you want one of these over a microcell (commonly misrepresented as a "Cell phone booster") is up to the persons needs. They have some other information on them also it seems.
Basically a microcell can broadcast a signal further depending on the booster used but on average they do, but it's not using legit cell signal, it's just creating a cell signal from the device, which is then routed through your home internet. No signal areas could be totally dead and zero signal at all however with signal so close to you it's unlikely, when using a signal repeater or booster you don't use your phones antenna.
While in the Verison store, the tech typed in an * or # number to bring my phone into synch.
