They generally come with a high gain antenna which can pull signal in much further away than your typical cell phone can. 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. It's never really using the cell tower at all. They have some other information on them also it seems.īasically 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. I found this to be an OK comparison, http //9/att-microcell-vs-cell-phone-booster/ 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. It's not just to take signal from outside and put it inside, you can have the whole system outside, and sit the phone near it and you will get more signal. A cell signal repeater or cell phone booster takes the outside signal, and then amplifies it. Mildly late to the party but there seems to be some misinformation in this thread, not entirely the poster(s) fault either. If you have high speed internet keep in mind you might be able to VOIP and not rely on spotty signal. calls get missed or dropped at times but its not bad (and i have a landline also so no big deal). i used to get 0-1 bars, after the update i get 0-3. every phone company has this as a dead zone as well. I'm at the very edge of a deadzone myself and besides what i said above there isnt much to do about it. my signal got boosted by 1-2 bars when i did this.

One thing i do recommend is to download the latest list of towers in your area. most major office buildings have such devices.

normally they are used to provide buildings with 'inside coverage' because steel and concrete can kill coverage. if you have zero signal the repeater will have zero signal. Signal repeaters (which i think is what you looked at) are good at providing a signal in the general area provided they have a signal themselves. pretty good way to increase your chance of brain cancer by using those. the few that do work also magnify the signal past the limits set forth by phone manufacturers. The antenna-like devices you put in phones generally do not work.
