AT&T Enhances Mobile Broadband Coverage at World’s Largest JW Marriott

INDIANAPOLIS, Oct. 12, 2011 /PRNewswire/ — As part of its continuing network
investment to support growing demand for advanced wireless devices and services,
AT&T* today announced that it has expanded its mobile broadband coverage at the
JW Marriott Indianapolis Downtown by completing the installation of a new
Distributed Antenna System (DAS) to serve customers throughout the facility.

“We are thrilled to have the reliable wireless service the new DAS provides for
our guests at the JW,” said Scott Blalock, general manager of the JW Marriott
Indianapolis.

A DAS installation consists of several strategically-placed antennas that
distribute AT&T’s wireless network coverage throughout the hotel complex,
providing for more efficient management of wireless capacity in
heavily-trafficked areas. DAS has the ability to provide enhanced wireless
coverage to customers in indoor or outdoor spaces where geographical limitations
- terrain, building construction, etc. – or crowd density might otherwise
prevent an optimal wireless experience. The additional capacity is expected to
help improve call reliability and enable more consistent network access to help
customers make the most of their AT&T devices.

“Indianapolis is known as a world class host of major events, which is why AT&T
is investing here in our wireless network,” said AT&T Indiana President George
S. Fleetwood. “We know how much people rely on their mobile devices when they
are away from home, so it is appropriate that we are expanding the capacity and
improving the reliability of our network at one of the premier hotels in our
city.”

This network improvement is part of AT&T’s plan to invest in the $20-billion
range in its national wireless and wireline networks in 2011. AT&T invested more
than $225 million in its wireless and wireline networks from 2008 to 2010 in the
greater Indianapolis area and nearly $925 million statewide during the same time
period. Already this year in Indiana, AT&T has activated over 20 new cell sites,
upgraded more than 80 existing sites with mobile broadband technology, and
expanded wireless capacity at more than 300 sites.

“We want our customers to have a great network experience whatever they’re doing
- whether making calls, checking e-mail, downloading apps or surfing the
Internet – while in Indianapolis for sporting events, or business and pleasure
all year long,” said Brian Ducharme, vice president and general manager for AT&T
Indiana and Michigan. “We’re committed to our investment in the local wireless
network, and providing enhanced wireless coverage at the world’s largest JW
Marriott is just one way we’re investing in Indianapolis.”

AT&T is an industry pioneer in delivering the benefits of mobile broadband
networks, devices and applications. With the nation’s fastest mobile broadband
network, AT&T provides accelerated mobile data speeds and simultaneous voice and
data capabilities for an amazing wireless voice and data experience. The
company’s recently announced agreement to acquire T-Mobile USA represents a
major commitment to strengthen and expand its network. If approved, this deal
means that AT&T will be able to expand the next generation of mobile broadband -
4G LTE – from its current plan of 80 percent of the U.S. population to more than
97 percent.

AT&T’s mobile broadband network is based on the 3rd Generation Partnership
Project (3GPP) family of technologies that includes GSM and UMTS, the most
widely used wireless network platforms in the world. AT&T has the best
international coverage of any U.S. wireless provider, providing access to voice
service in more than 220 countries and data service in more than 200 countries.

AT&T also operates the nation’s largest Wi-Fi network** with nearly 27,000
hotspots in the U.S. and provides access to nearly 190,000 hotspots globally
through roaming agreements. Most AT&T smartphone customers get access to our
entire national Wi-Fi network at no additional cost, and Wi-Fi usage doesn’t
count against customers’ monthly wireless data plans.

AT&T recently launched “Focus: Indianapolis,” which provides visitors a peek
into AT&T’s wireless network enhancements made since the beginning of the year.
Enhancements include new cell sites, broadband speed upgrades, capacity upgrades
and network connection upgrades. The site also provides a map of area AT&T
stores, a map of area Wi-Fi hotspots, useful tips, a localized Twitter handle
and device reviews. You can visit the site at http://focus.att.com/indy.
