Flush Mount Cell Site on PG&E Transmission Pole - San Jose, CA Airport2293 viewsThe interesting point about the cell antennas mounted to PG&E's transmission pole (seen in the right side of the photo) is that the antennas are not out on arms. Usually power companies require carriers to mount antennas on arms to insure adequate climbing space under NESC/CPUC GO95.

NextG Distributed Antenna System Node755 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).

Not too compliant with the FCC OET Bulletin 65 Rules574 viewsThe FCC rules require that where visitors (and even trespassers) are expected, a wireless carrier must protect those members of the general population from RF exposure exceeding the uncontrolled standard. This site does not meet that requirement due to the antennas mounted on the exterior fence of this water tank site.

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 Node429 viewsNextG is a wireless carrier's carrier. They provide fiber links between the BTS and the antenna site using a technology referred to as Distributed Antenna System (DAS). This is a NextG DAS node located in Encinitas, California. The carrier supported by this node is Cricket Wireless. NextG's Cricket network in San Diego County is thought to be the largest deployment of DAS in the U.S.

Multi-carrier cell site and TVRO downlink425 viewsThe multiple carrier tower isn't connected with the TVRO satellite antennas in front, but it makes for a nice picture. This site is located in northern San Antonio, Texas at a very large church facility. An interesting note: The antenna structure registration number shown on the site is, per the FCC's database, cancelled. Interesting!

Sprint Conducts a Drive Test425 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.

Sprint Conducts a Drive Test408 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.
