American Tower Deploys In-Building Distributed Antenna System
American Tower upgrades system to meet the needs of a major national carrier

BOSTON, Jan 31, 2011 (BUSINESS WIRE) --

American Tower Corporation (NYSE: AMT) today announced that it has deployed and is now operating its first 700 MHz Long Term Evolution ("LTE") Multiple In Multiple Out ("MIMO") In-Building Distributed Antenna System ("DAS") network at the Las Vegas Hilton in Las Vegas, Nevada in coordination with the launch of a major wireless carrier's 4G LTE network. This represents American Tower's first in-building LTE MIMO network out of more than 200 DAS installations.

American Tower deployed the network to support the carrier's keynote address highlighting their vision for LTE 4G wireless technology and the rollout of new 4G devices at the 2011 Consumer Electronics Show ("CES") in Las Vegas. This project represents not only a milestone of new technology, but also of process and efficiency, as it required significant coordination and was completed in less than four weeks with minimal disruption to hotel operations. This was achieved by implementing MobileAccessVE, a network solution which allowed American Tower to utilize existing cabling from the legacy DAS network.

"We were pleased to deliver this DAS network in time for an important industry event and 4G product debut," said Gerard Ainsztein, American Tower's Senior Vice President of DAS Solutions. "This has been a very exciting project, and we are proud to have played a part in helping a major national customer share their advanced 4G wireless network with the consumer electronics industry."

In addition to the 700 MHz LTE MIMO installation at the Las Vegas Hilton, American Tower recently completed another DAS installation in the Kansas City Convention Center in Kansas City, MO in December of 2010. These installations add to the company's growing portfolio of over 200 in-building and outdoor DAS networks.
