I only had about one bar on the phone and I used one of these for a while before I found a WISP in the area. It worked pretty good, gave me about triple the bandwidth going from about 1.5-2 mbps to 6-7. I plugged it right into the verizon mifi puck and just bridged the wifi it outputs to connect it to my home network. Used a weBoost for inside the house to improve other phone signals and still have that setup, it kind of worked for the puck but the external mimo was a lot better.
Yet I don't think this is what CBS wants people to take away from this. The CBS headline says terrorism and goes on about the government's report confirming but most folks won't even read past that headline.
