I live 5 miles north of town. The service outside my house is bad, but good enough to make and receive a call. Inside the house, the service falls just below the level of being usable. Data is out of the question inside and out.I bought the zBoost, hoping to get my outside signal inside, that didn't happen. Like many other people that have reviewed this product, I found that the coverage area isn't 2,500sq/ft its more like 12.56636sq/ft. If my phone was within 2ft of the base station, I had full service and could make calls. Moving further than 6ft from the base station, I would be returned to 1 or none bars.On the bright side, amazon is a rock star dealing with returns, and I still fully back them.For sprint users, which I am a new one. I called and told them about my problem. I qualified as a premier member (pay more than $70 a month or be with sprint for 10+years qualifies you). They were extremely nice and provided a Airave V2 Femtocell tower. The Airave arrived, and after waiting for 2+hours for the unit to configure the mobile portion of the setup, I found I had full, 3g service, everywhere in my house. Any one who is a sprint subscriber, I strongly recommend you don't buy the zBoost and contact sprint about a Airave V2. It requires a high speed connection of 40k up and down, pretty easy bar to meet these days. I am 100% satisfied now, and have healthy, reliable service everywhere in my two story house.If you're a security nut like myself, you can setup the Airave V2 as the DMZ host behind your router. Mine seems to work perfectly in this configuration. Now I don't have to worry about sprint monitoring my network traffic either, its a win win solution.
