Several of our street lights have this antenna & box affixed to them. Anybody know what they are, or are used for? I seem to remember some wireless data service from many years back expanding into metro areas before going bust- leftovers from them? From the name on the boxes, it's Metricom, who went under in 2001. Still up, 9 years later? Or has some other organization taken over these boxes and repurposed them?
