12. Close-up of GPS antenna and top of Cable Tray586 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.

Co-location cell site - sectorized and omnidirectional578 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.

11. Cables are now in the Cable Tray575 viewsWe're getting closer! Notice that the cables make a gentle (less than 90 degree) bend at the bottom of the ladder where it connects to the tray in the hallway. Bending cables too much can kink them. Kinking can cause excessive signal transmission losses. Not a good thing! Also notice that the GPS antenna is now installed--quite visibly--at the top of the cable tray on the roof. More in the next photograph...

CellSign Updated575 viewsThis AT&T wireless site has been modified since the last time we photographed it. Search for "Pico" to find the original site configuration. Originally, this was a single band site; now this is a dual band site. The boxes adjacent to the amplifiers are called "tower mounted amplifiers" (TMAs).
|
|
External co-location monopole574 viewsOne way a co-location wireless site is created is by externally-mounting the cables and antennas to an existing monopole. This example shows what can happen when the added cables are not covered or otherwise specified to minimize visual impact.
The carriers at this site are Verizon Wireless and AT&T Wireless (now Cingular Wireless).

Sprint Conducts a Drive Test570 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.

21. Huh? What Happended to the Concrete Pad?559 viewsIn a surprising twist, the concrete pad has been hammered out and new frames and conduits installed. What gives? According to the work crews, it seems that the generator pad was installed 90 degrees off. Go back in the gallery and look and you'll see what I'm talking about. Because of the little error, weeks were apparently lost in site activation...not to mention $$$ (which I didn't, okay?).

Sprint Conducts a Drive Test551 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.
