  AT&T Enhances Mobile Internet Coverage In The Detroit Marriott Renaissance

New 4G LTE Distributed Antenna System Provides Additional Wireless Capacity
for Customers

DETROIT, Jan. 4, 2013

DETROIT, Jan. 4, 2013 /PRNewswire/ -- As part of its continuing network
investment to support growing demand for advanced wireless devices and
services, AT&T* has improved its mobile Internet coverage at the Detroit
Marriott Renaissance Center by completing the installation of a new 4G
LTE-capable Distributed Antenna System (DAS). 


A DAS installation consists of multiple strategically-placed antennas that
distribute AT&T's wireless network coverage throughout the Marriott, providing
for more efficient management of wireless capacity in heavily-trafficked areas
including guest rooms, the hotel lobby, ballrooms, guest circulation areas,
meeting rooms, executive offices, fitness club, and more. DAS has the ability
to provide enhanced, more consistent wireless coverage to customers in indoor
or outdoor spaces where geographical limitations – terrain, building
construction, etc. – or crowd density might otherwise prevent the optimal
wireless experience.

"We want our customers to have a great network experience wherever they are,
no matter what they're doing – whether that's making a call, checking email,
downloading apps or surfing the Internet," said Jim Murray, president of AT&T
Michigan. "We're committed to our investment in the local wireless network,
and providing enhanced wireless coverage at Renaissance Center is just one way
that we're investing in Detroit."

The additional capacity is expected to help improve call reliability, boost
data traffic capacity and enable more consistent network access so customers
make the most of their AT&T devices.

This unobtrusive network solution is just one innovative approach AT&T is
taking to ensure it provides a seamless and effortless customer experience.
AT&T's innovation and investment have resulted in the nation's largest 4G
network, covering more than 285 million people with ultra-fast speeds and a
more consistent user experience. That's coverage in 3,000 more 4G cities and
towns than Verizon.^**

AT&T has deployed two compatible 4G technologies to deliver more speed to more
customers, which means AT&T customers can get 4G speeds outside of 4G LTE
areas on 4G HSPA+, unlike competitors, where smartphone customers fall back to
slower 3G technologies when outside of LTE coverage. Our 4G LTE network
delivered faster average download speeds than any of our competitors in
PCWorld's most recent 13-market speed tests.

AT&T's 4G LTE network delivers speeds up to 10 times faster than 3G^***, as
well as multiple innovations that optimize the network for performance. Our
network's radio components are placed close to the antenna at most cell sites,
instead of inside the base station, which helps minimize power loss between
the base station and antenna and, in turn, improves the performance of our 4G
LTE network. The network also is designed with its core elements distributed
across the country, which helps reduce latency, or the delay when using the
Internet, because your request isn't traveling as far.

AT&T's focus to deliver the best possible mobile Internet experience goes
beyond 4G and DAS to embrace additional connection technologies. AT&T
operates the nation's largest Wi-Fi network**** including more than 31,000
AT&T Wi-Fi Hot Spots at popular restaurants, hotels, bookstores and retailers
across the country. 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.

Over the past five years, AT&T invested more than $115billion into operations
and into acquiring spectrum and other assets that have enhanced our wireless
and wired networks. Since 2007, AT&T has invested more capital into the U.S.
economy than any other publiccompany. In a July 2012 report, the Progressive
Policy Institute ranked AT&T No. 1 on its list of U.S. "Investment Heroes."
