Co-location cell site - sectorized and omnidirectional527 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.

RF on the Roof526 viewsThis commercial building in Tarzana, California shows how to poorly plan a roof by sticking almost anything (antenna wise) on the roof. A very poor (or good, depending on your view) example of how not to plan a rooftop.

Penthouse external mounted site525 viewsThis is a plain, externally mounted cell site on a commercial office building. Note the GPS (timing) antenna well above the roof line, which might have been mounted at the roof level to minimize its visibility from ground level without impairing its function.

Lots of BTS Equipment in the Sidewalk Area523 viewsHere's a close-up photo of the AT&T Wireless BTS in the public right-of-way (sidewalk). Notice how tall the equipment stack is (about 6').

Sprint Conducts a Drive Test523 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.

CellSign Updated523 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).

Take me to the Opera!523 viewsThe BTS cabinets for the multi-carrier sites (on parking lot lights) at the Santa Fe Opera in Santa Fe, New Mexico.

Cell site and Microwave Relay522 viewsThis site is not a mobile telephone switching office (MTSO). Rather, its an aggregation point for microwave backhaul from other wireless sites. Verizon and Nextel are co-located here.
Why red and white? This site is located adjacent to the Ontario, California airport.

Blessed Be This Cell Site521 viewsAT&T's monopole at the Calvary Community Church in Phoenix sports not one; not two; but three crosses mounted at the corners of the radomes. Quite an interesting design!

Sprint Conducts a Drive Test519 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.
