We're getting some new street lights and have noticed they have little
antennas on the top.

What is it for?


It's so they can be switched on and off remotely.


and report back to base when they are "broken". Apparently, it costs less
to pay extra for all the electronics in the lamps than send a man around
once week to check. (Except the checking probably got "cut")

they communicate using a Zigbee mesh network, if you wanna look that up

Thanks!
