93, that's where I'd be concerned. I'd ask to do a trial run with it and make sure it works in your house (and other main places you'd consider taking it).
In my first apartment with it, there was only one corner of the living room it worked in.
We're in the center of the coverage area. We've got three towers around us, and the signal sucks.
It is often slow, and sometimes there is no connection.
It is awful.
