[Ham-80211] What is it? (probably off-topic)

"Repeater in a box", nice piece of hardware, but what can we use it for? 
These frequencies are not, I think, within HAM bands, and, if I 
understand, most cell phones are now out of these bands as well....
Seems a shame to take it apart, and just salvage the components...
