Ricochet, the wireless ISP, used a system like this. Ricochet went out of
business around 2001. One of their transmitters was on a light pole in my
neighorhood up until about a year ago when a development removed it. I was
on Ricochet and it worked real well. They just could not sustain the
business. Maybe someone changed the frequencies of some of their old
transmitters.

It could have also been an early attempt at a TIS service, employing
multiple 
low-power transmitters to cover a given area.

Some time ago, someone provided a link to a company that sells these kinds
of 
low-power "repeaters" to permit Part 15 compliant emitters to be placed such

that many miles of road can be covered, or a whole town, etc. The major 
drawback of the system (IMHO) is that it uses an ISM freq in the 13Mhz band
(NBFM) 
to relay the station audio to the Broadcast-Band repeaters. (AM or FM.) They

were not cheap.

I wonder if these streetlight units we are discussing are remnants of an 
operation like this. Apparently, it went belly-up long ago and the
transmitters 
were all just left in place to rot.
