29. Which Way Tray?472 viewsIt's now January, 2006. The site is active (but without a backup power generator). It seems that the installers missed putting all of the covers on the cable tray. Too bad.

A Tower That Helps Birds!472 viewsThis is American Tower's "Taos Center" tower site in, ah, Taos (New Mexico). It's most unique feature is the federally protected bird's nest on the tower. Here's the sign warning against climbing without permission.

Building side mount omni site468 viewsNotice that the omnidirectional antennas are mounted on the side of the building near the corner. Even more interesting is that the GPS antenna (used for network timing) is mounted in such a way as to be shielded from about 120 degrees of sky (this site faces northwest).

Sprint Conducts a Drive Test468 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.

Co-location cell site - sectorized and omnidirectional461 viewsA single monopole tower can support one or more sectorized carriers. The lower carrier does not use diversity reception (two receive antennas spaced so as to better receive lower power mobile handsets). The upper carrier does use diversity. Usually, in diversity configurations, the two receive antennas are on the outsides of the sector, and the transmit antenna is located inside, adjacent to one of the receive antennas.

Sprint Conducts a Drive Test461 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.

12. Close-up of GPS antenna and top of Cable Tray439 viewsAs noted before, the cables are carefully pulled on to the roof so as to prevent kinks. The GPS antenna provides system synchronization time signals. This location is inferior as it can been seen from the ground. A better location would have been on the roof away from the edge so as to hide this element.
