Das da ticket!643 viewsA close up of the AT&T Wireless DAS antennas. Note several things:
First, the RF warning sign is on the rear of the antenna, where is cannot be seen by someone approaching the antenna. This is not consistent with the FCC RF safety requirements.
Second, these are dual band antennas. In the far antenna, the cellular band antenna feed is on the right; the PCS band feed is on the left.

NextG Distributed Antenna System Node826 viewsNextG's DAS node located in Encinitas, California. The carrier supported by this node is Cricket Wireless. The DAS equipment manufacturer is Andrew Corporation. This DAS node is a member of Andrew's ION ("Intelligent Optical Network") line of products. The cover at the top of the DAS housing covers a cooling fan.
Under SDG&E rules, this site does not consume enough power to require a power meter; merely a breaker box (located to the right of the DAS node).

Sprint Conducts a Drive Test469 viewsThe tech mounts the omnidirectional antenna to the telescoping mast. Once the antenna is mounted, he'll connect the coax that runs back to the portable PCS transmitter sitting inside the van. Then the tech will elevate the antenna to the desired height, and set the proper output power of the transmitter. With all this done, another tech will drive the streets in the area recording signal strength, latitude, and longitude for later mapping.

PCS-Transmitter-in-a-Box449 viewsWhen a wireless carrier selects a candidate cell site it will usually conduct a 'drive test' to determine actual coverage. The drive test consists of elevating an antenna (here, an omnidirectional antenna) to a predetermined height. Inside the truck is a portable PCS transmitter powering the antenna.
This is a photo of the PCS transmitter used by Sprint in this drive test. What? You thought it would be larger?!

Sprint Conducts a Drive Test475 viewsWhen a wireless carrier selects a candidate cell site it will usually conduct a 'drive test' to determine actual coverage. The drive test consists of elevating an antenna to a predetermined height. Inside the truck is a portable PCS transmitter powering the antenna. In a separate vehicle (call it a 'rover') the carrier will drive the streets around the test site out to a predetermined distance from the site. The received signal level and GPS location information are stored in a portable computer inside the rover.
After the test is concluded, the received signal strength and location information are plotted on a street map. That map then serves to guide the RF engineer to select a final candidate site, and to design the antenna system to cover the desired area without causing unreasonable interference to other cell sites on the same network.
Attached to the left of the antenna (and blowing in the breeze) is a measuring tape used to determine the height of the antenna.

What's that wrapping around the antennas?598 viewsHere's an interesting site (close up in next photo). Notice that there are cars parked in the auto body shop lot directly below the antennas. Perhaps birds like to take aim and, er, hit the cars below. What a clever carrier solution! Put a net around the antennas to keep the birds off.
