I've seen several of these devices attached to the street light poles
in Irvine, CA. Clearly there is some kind of radio inside the box, but
what is their purpose?

Could also be a microcell for cellphones. Ours are usually mounted about
halfway up the pole.
I can't make out the blak dome above. It may be a photocell to turn lighting
on at dusk, or perhaps a GPS antenna. If GPS, then the unit may be a DGPS
transmitter.
