Utility Pole Antennas
A toddler, a baby and a puppy. They all do better when you take them outside for a walk from time to time. It's amazing the things you notice walking. Walking instead speeding at 40 MPH through your 25 MPH neighborhood. I've been noticing antennas.Lets begin our little journey with telephone poles. Ok, utility poles. They are now sprouting antennas of various types. We are really loading up these poor, dead, tar-covered trees.
The photos below were taken within a 1 mile stretch near Palos Verdes Drive North in Palos Verdes Estates, CA.
Cellular sector antennas (painted brown) pointing at Palos Verdes Country Club and Palos Verdes Dr. N. Also note the three small white antennas and radio connected directly to cable. I believe this is an "old" Cox communications PCS cell. Cox Communications sold their PCS business to Sprint. These Cox cable-attached trio antennas are everywhere around Palos Verdes Estates. I suspect they are not in use. Anyone know the story?
Sector antennas aimed at Palos Verdes Drive North. I believe this is Sprint wideband PCS. Also see what looks like an old Ricochet antenna above the PCS antennas.
Close-up
This pole is between two houses, within four feet of a driveway. It might be worth changing wireless providers when there is a cell in your front yard.
Close-up. Time to trim the tree.
This picture is a bit underexposed, but you can see the silhouette of the two Sprint PCS isopole antennas on the right side of the pole and the three old Cox antennas on the cable to the left. This is a Sprint PCS site. There is a phone number for the Sprint Network Operations Center (NOC) on the equipment.
Close-up of the radios mounted on the pole at a height of 7'. I'm surprised by how vulnerable this cell site is. RF cabling is exposed within arm's reach.
So, I'm not surprised to see so many of these micro cells popping up, that was always the vision for cellular communications systems... smaller, lower-level cells as the needs for capacity grow. I am surprised by how physically insecure these cells are. I am surprised that the antennas have trees in their radiation path, that's a problem at 1.9GHz. I guess the cellular providers just have to live with trees in residential areas.

That's...weird
Lots of this going on in Sydney Australia when I was back there recently. Particularly fun are the sites with a 12" microwave dish *and* a mini cell antenna or two. I.e., they apparently take a feed via microwave and then radiate locally for cell phones.
This is the sort of half-assed cellular infrastructure that did not hold up in New Orleans hurricane and flooding.
