George,
That's a kind of a cool gadget.
Still harkens back to the high-gain analog set-up we used in the Phoenix One. It was a 3-watt analog transceiver that I tweaked to a higher performance level + coupled with a high-gain antenna -- but the network was decidedly 0.05G.... I built a splitter that worked pretty well...
The biggest issue I see with the MiFi 2372 is the lack of high-gain antenna and, of course, the lack of nodes out in the backroads. Mike Booth and I keep missing each other -- but truckers are at the forefront of internet access these days -- they require good web connections to assemble their loads. I'll try and connect with him today.
