Hi Dennis,
I found the origin of the video on this site:

I think it is essentially the same set up as Judy uses, but the router and "air card" are combined together in one box and packaged together with a special antanna system. The antenna may be the most interesting part. Antennas are a mystery to me, but the system they are using with two separate antennas (transmit and recieve?) is unlike anything I have seen before. You understand antennas much better because of your ham interests. They are claiming something like 20 to 30 mile range. They only provide the hardware to trasmit a mobile WiFi signal. You would have arrange for the cell service from Verizon or Sprint etc. Sounds like the same package as the one that Judy has with Verizon.
Anyway, we hope that you and Mary Kay are keeping well. We were sorry to hear of the loss of your furry friend, we have been along that path too many times, and you have our sympathy.
