My office has just done some rearranging of where people are working and several managers have got moved to our basement level where there is next to no cell signal. Since the managers are from our finance department they are willing to spend the cash on a booster, and its my job to find one.

Does anyone know of a good, reliable cell phone extender that can do the job. Ideally, I'm looking for one that will work with all the major phone networks, Verizon, Sprint, AT&T, but if I need to be restricted most of the people that need this are on Verizon, which I can make my Pre roam if I have to.

Thanks for any recommendations.
