The cell phone provider AT&T will move its SLAC-based cell phone tower from its temporary location behind Building 50 to its permanent home, with its antennae on the roof of the building. Construction is scheduled to begin soon and last into May. Tear-down of the old tower will not begin until the new site is operational, so as not to interrupt AT&T's service. SLAC employees should expect to see subcontractors working around Building 50 during the months of April and May.

"AT&T always intended the current tower to be temporary, and now they are following through to put a permanent tower in place," said Les Cottrell, SLAC's manager of computer networks and telecommunications and project manager for the AT&T project. "They want to do this right."

In 2008, SLAC management approached AT&T about joining the cell phone carriers T-mobile, Sprint and MetroPCS in providing a cell phone tower on the SLAC campus. The cell phone tower's antennae receive signals from cell phones and broadcast them to the carrier's nearest mobile telephone switching office, where they are connected to the service provider's backbone network. The signals going to and from the antennae can be interrupted by buildings or other obstructions, so they are usually placed high above the ground. In addition, each antenna can handle only a limited number of user signals, so the cell phone towers must be spaced close enough together to support the local volume of users.
