My microcell covers about 5000 sq feet there's not a place in my house that I don't get five bars, when I walk outside the signal slowly falls to about then 3 bars at the street then switches to the local cell. My Wi-Fi from the RG though stay connected until I drive down the street on my Iphone.

I do have everything on AT&T but no word if I get any discounts on the unlimited calling, unless I get it free I wouldn't get unlimited calling doesn't make sense. I'd just spend that 20 bucks on a bigger cell plan then I could use the minutes anywhere. I would say if you have a very weak signal or want to ditch the landline this is a good investment, otherwise save your money.

Great blog from a guy here in Charlotte who installed the very first day http://jasonnash.wordpress.com/2009/09/22/review-of-the-att-3g-microcell/
