TAILIEUCHUNG - In 1999, LBNL asked the area’s cellular carriers to propose a solution to the problem. Cingular Wireless (previously Cellular One and AT&T Wireless) proposed installing an InterReach in-building wireless system. After the IT staff determined that the in-building system wouldn’t interfere with sensitive scientific instruments such as electron microscopes, Cingular got the go-ahead to install it.

Located on a 200-acre site in the hills above the University of California s Berkeley campus and overlooking San Francisco Bay Berkeley Lab is the oldest of the . Department of Energy s National Laboratories. LBNL was founded by Ernest O. Lawrence Nobel prize-winning inventor of the cyclotron which pioneered new areas in atomic and subatomic research. LBNL s main site now consists of more than 100 buildings where some 3 800 research engineering student and administrative personnel conduct unclassified scientific research in a variety of disciplines. The lab s research areas include fundamental studies of the universe quantitative biology nanoscience new energy systems and environmental solutions and the use of integrated scientific computing as a tool for discovery. The Lab is also home to four DOE national user facilities. The problem is that the hill-and-valley topography of the site leads to inconsistent and sometimes nonexistent cellular coverage buildings on hilltops receive good coverage while buildings located in the valleys and sometimes built into hillsides have little or no coverage. It s a large campus and many of our employees have offices in one location and then spend a lot of time in labs at another location so cellular phones had become the primary method of communications said Stephen Nobles a project manager in the IT Infrastructure department at LBNL. We had to find a way to make sure those phones worked. CASE STUDY In 1999 LBNL asked the area s cellular carriers to propose a solution to the problem.
