Parking the Signal149 viewsParking spaces make good sites for BTS cabinets, GPS, and LMU equipment! And parking lot walls are great for mounting panel antennas, especially when the parking lot faces a major freeway. This site is near LAX airport in Los Angeles along the San Diego Freeway at Century Boulevard.
|
|
Church Bell Tower With External Antennas165 viewsThis church bell tower sports multiple panel antennas on the face of the structure, rather then flush or camouflaged inside the tower. Too bad. Certainly not a high quality installation. Spotted in South-Central Los Angeles.
|
|
Spectrasite Co-Lo Multisector at Different Levels232 viewsSpectrasite tower supports a three sector wireless system, with one of the sectors lower than the other two (to help shape coverage). Also, this site supports an omnidirection carrier (the vertical antennas on top of the tower).
|
|
Verizon MTSO San Diego 2 of 2241 viewsThis photo shows Verizon's Mobile Telephone Switching Office and tower in San Diego, California. The microwave antennas connect various cell sites back to this MTSO. Telephone company leased data lines (usually T1 circuits) are another means of connecting remote cell sites back to a MTSO.
|
|
Verizon MTSO San Diego 1 of 2194 viewsThis photo shows Verizon's Mobile Telephone Switching Office and tower in San Diego, California.
|
|
A Real Education214 viewsThis Cingular site is located on the grounds of Fountain Valley (California) High School.
|
|
A New Sign of the Times188 viewsYes, this cell site is sandwiched between two outdoor advertising signs. Yes, two of the three sectors shine THROUGH the signs (with metal rails just in front of the panel antennas).
|
|
Really, really flat vines on this pole!188 viewsA Spectrasite site in Montebello, CA.
|
|
Sprint microcell - Two Sectors411 viewsPole mounted Sprint microcell in Brentwood, California (Parkyns St.). The panel antennas should have been painted brown or green to afford some measure of camouflage. This site is near OJ's former home on Rockingham in Brentwood, California. It's a much nicer area than were he now lives in Nevada.
|
|
Yahoo! What a site!236 viewsThis omnidirection site is in Santa Monica, California. The GPS antenna is the right (north) of the antennas on the roof.
|
|
Single Carrier Monopole230 viewsNot much to say about this site. It's a monopole that happens to be located at the top of a hill next to a water tank.
|
|
Spectrasite in Paramount, California179 viewsYet another Spectrasite installation, this time in Paramount, California (looking north).
|
|
Spectrasite in Paramount, California163 viewsYet another Spectrasite installation, this time in Paramount, California (looking west).
|
|
Hitting the signal out of the park208 viewsSprint's three-sector site is split between one sector on an existing light standard, and two sectors on a pole it installed.
|
|
Cell site and Microwave Relay252 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.
|
|
Sending out the word...to Interstate 10200 viewsYet another church along a freeway that (likely) enjoys income in the thousands-of-dollars-per-month range. This is a Nextel site near San Bernardino, California.
The interesting and unusual element of this site is the placement of the antennas following the rise of the roofline. In a typical configuration, the two outside antennas are used for reception, and the center antenna is used to transmit, and they're all on the same horizontal plane.
|
|
Nextel's Interesting Lattice Tower280 viewsA Nextel site using an interesting lattice tower to support its antennas and microwave antennas.
|
|
Sprint's Drive Test Rover252 viewsThis is a Sprint vehicle used to receive the test signal emitted from the temporary transmitter van. This van drives a predetermined area collecting signal strength data for later mapping.
|
|
Rover's Roof270 viewsOn the roof of the drive test 'rover' is a GPS antenna (the square antenna in the center of the roof), plus two PCS omnidirectional antennas for signal measurement and communications purposes.
|
|
Drive Test Rover Ready To Run221 viewsInside the cab of the drive test 'rover' is a portable computer connected to the output of the PCS signal strength receiver and the GPS receiver. The computer records the data for later mapping. The clipboard holds the predetermined route that the driver of the rover will cover during the test.
|
|
Sprint Conducts a Drive Test249 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-Box239 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 Test272 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.

Equipment Cabinets, GPS and LMU antennas281 viewsCingular's equipment cabinets are mounted in the hardscape area between the curb and sidewalk.
|
|
Close-up of GPS Antenna and LMU Antenna245 viewsCingular's GPS antenna (left) and the LMU antenna are mounted at about the 5 foot level adjacent to the sidewalk. It's amazing that they're still there. Hope no pedestrians walk into the bracket at night.
|
|
Utility Wood Pole Top Mount238 viewsCingular's three sector antenna system is mounted at the top of the utility pole it installed (it has a PBM pole number). The equipment cabinets are located to the right of the pole.
|
|
Tip-to-Tip 1 of 2191 viewsThis equipment cabinets of this site are behind an unlocked gate. Many of the cable conduit pull caps have been removed exposing the site wiring.
Note the antennas mounted in a "tip-to-tip" configuration. A close up of the antennas is seen in an adjacent photo in this gallery.
This site is located in San Francisco and shines signal on US101.
|
|
Tip-to-Tip 2 of 2220 viewsHere are four antennas mounted in a "tip-to-tip" configuration. Notice the faux antenna cover used to blend each of the two vertical antennas on the right side of the pole. Also clearly seen are the antenna downtilt mounts, and pole-mounted pre-amplifiers.
This site is located in San Francisco and shines signal on US101. The equipment cabinets for this site are seen in an adjacent photo in this gallery.
|
|
Flush Mount Cell Site on PG&E Transmission Pole - San Jose, CA Airport211 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.
|
|
Multi-carrier Omnis and Panels214 viewsOn the west side of Interstate 5 in San Diego County, California.
|
|
Multi-Carrier Panels238 viewsJust west of Interstate 5 in San Diego County, California. Notice that anyone can walk up to the ground-mounted panel antennas via the path in the foreground. This site is not fenced.
|
|
Cell Sign201 viewsSpotted in Redwood City, California, this two sector cell site provides spot coverage along the US101.
|
|
Galt High School Doesn't Lack for Signal258 viewsThree out of four light standards at the Galt (California) High School Warrior Stadium are cell sites. Well, that still leaves 25% growth potential!
|
|
Sending out the word...to Los Angeles International Airport212 viewsThis is an AT&T Wireless site just north of LAX. It's a rather poor design Notice (1) the panels just above the roof line; the microwave panel antenna offset from the bell tower; and the cable runs down to the equipment building. A good design element (perhaps the only one) is the use of the brick face on AT&T's pre-fab building.
|
|
City Hall Clock Tower254 viewsIrvine, California's civic center is a sight to behold. The clock tower above the site supports public safety radio antennas, and an omni-direction antenna cell site.
|
|
CEV Hatch with Bench360 viewsThe metal bench sits atop the hatch of a CEV (controlled environmental vault) used to house telecommunications equipment in a large, underground room. How large is large, you ask? CEV's are common, but bench tops aren't.
CEVs come in many sizes, but its common for the size of the room below ground to be measured in hundreds of square feet.
|
|
Guyed Tower - Antennas Vertically Stacked196 viewsThis cell site is on a guyed lattice tower on top of a commercial building in Modesto, California. Notice that the antennas are vertically stacked "tip-to-tip" at the top of the tower.
|
|
A Modest Cell Site?211 viewsThis water tank sports multiple panel antennas. Modesto, California.
|
|
PCS at City Hall214 viewsThis Sprint site at the Redondo Beach, California City Hall also supports public safety radio antennas above and below the panels.
|
|
Building top multi-sector cell site160 viewsPlain vanilla. No "touch of gold" here.
|
|
Building top multi-sector cell site277 viewsYet another roof-top cell site. This is a macrosite adjacent to a major freeway in Los Angeles.
|
|
Top Hat Wireless?196 viewsHere's a different spin on hanging antennas from a pole. The other poles along this strand line are shorter, but AT&T Wireless replaced the existing pole with a taller one to provide room at the top to hang its three sectors of panel antennas.
|
|
Microcell Bolted on Parking Lot Light241 viewsSpotted in Glen Ellyn, Illinois, this microcell site is bolted to the top of an existing parking lot light standard. Notice the equipment mounted in the grass area (hey, guy, open that car door slowly or you might hit something).
|
|
Oil's Well that Emits Well154 viewsOld oil wells can make good cell sites, even when a building has been built around the base!
