American Tower Deploys Outdoor Distributed Antenna System Network in Barrington Hills, IL

American Tower Corporation (NYSE: AMT) today announced that it has deployed an outdoor distributed antenna system (DAS) network in Barrington Hills, Illinois in response to increasing wireless coverage needs. The system was completed in February 2010.

American Tower has designed a multi-carrier system in the Barrington Hills area. American Tower’s outdoor DAS utilizes existing utility poles in the public right-of-way. AT&T is the anchor tenant on the system.

In late 2009, American Tower completed another large-scale outdoor DAS network in Gross Pointe, MI. "Our increasing focus on outdoor DAS networks results from our customers’ unique needs to expand their network coverage in areas where traditional wireless tower sites are not an option. They allow wireless service providers the ability to deliver the coverage they need while balancing community aesthetic demands and zoning requirements,” said Gerard Ainsztein, American Tower’s Senior Vice President of DAS Solutions. "We own and operate approximately 200 in-building DAS networks in malls, casinos and other in-building applications. The offering of outdoor DAS networks has been a logical extension of our well-established in-building DAS networks program as a complementary shared infrastructure solution for our customers.”
