I have Verizon service now, and at my house I do not have any reception here(cell dead zone) so I use one of their fem-to-cells. I was under the impression that the airave acted the same way. The Verizon one does not need any cell reception to work, it gets it through the internet (my understanding anyway). The airave I have learned from ting tech support has to have at least one bar to work. Kinda killed my hopes and dreams of saving $150 month on service. I hope this helps somewhat for others in my situation.
