Birds on Blue Unique Cell Site Design - Public Art461 viewsThis public art cell site was designed by Ron Pekar and Sandy McDaniel; brought to life by Esteban DuPont's CellTech Wireless, sponsored by Crown Castle, and authorized by the City of San Diego. This is a wonderful result for a great collaboration. Located at CA905 and Beyer Blvd in San Diego.

Sprint Conducts a Drive Test460 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 Test447 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.
