one thought about these : this device is located on a utility company
light pole. it's highly unlikely that it belongs to anyone
commercial other than the utility company / or the " city of "
people.

Are we looking at equipment left over from the old Metricom Ricochet
service? Their strateqy was to operate a mesh network in the unlicensed
ISM band. By cutting a deal with the city to use lamposts they could
avoid having to pay the high utility pole attachment fees.

Did they ever serve Irvine, CA?

According to

http://www.ricochet.com/FAQs_Compari...verage%20Areas

the closest market they serve is San Diego.

That's what they looked like to me. I've seen them in Troy, Michigan also.

I'll accept something like that. What frequency range does the
terrestrial signal occupy?

I would have figured something smaller and several of them in a city,
not just one multi-kilowatt transmitter.

XM terrestrial repeaters are usually on large buildings or hills and
they use a several KW Klystron amplifier, which takes a 6ft rack for the
redundant pair. Don't think that is stuffed inside the lamp pole....

I forget the exact frequency, somewhere in the 2GHz range. Xicom makes
the amplifiers.

I am going to guess its a mind control transmitter to make drivers come
to a complete stop rather than a rolling one. Or it might keep vagrants
from washing windshields at intersections by making them consider
getting real jobs. :-). Mike Burch K8MB

I've seen these on some poles in upstate NY also.
Think they are used to signal the electric utility when
the streetlight goes out. You will note the round
power adapter that is sandwiched in-between the
125 VAC photocell which switches on the lamp.
These are a 3-conductor / pole twistlock connector.

Wireless Modem network from the late 90's. Before I retired I lived in San
Francisco a few years, these units were on light poles about one per city
block.
