</div>I just went up the construction scaffolding at 16th/mission and read<br>
the labels on the devices. The big ones seem to be 4.9 GHz to 5.8 GHz<br>
repeaters for the public safety cameras. The little ones are made by<br>
a firm named novalab and are labelled with FCC ID XMPNL72742. I don't<br>
know what they are, but searching around it looks like streetline, the<br>
parking meter people, use a 900 MHz mesh network which is probably<br>
compatible with that hardware.<br>
