Today’s Mobile Devices Mobile Device Evolution Driving Data Growth More capable Smartphones means more engagement with devices Legacy Mobile Devices Today’s Mobile Devices Phone Calls Email Limited Web Browsing Complex Applications Streaming Video Extension of Office PC Smartphones, Branded Computing Devices, and Emerging Devices AT&T has experienced unprecedented mobile Internet growth … 25,000% wireless data increase over last 5 years As smartphones have become more capable, customers have enjoyed using their devices more Older mobile devices didn’t have as many capabilities and were used mainly for placing calls, there was some email functionality, but there were no compelling applications. They had lower processing speed, smaller capacity, and they were more bulky. Today, phones have incredible processors, great resolution, and can support vary innovative applications and can even be used as an extension of an office PC. The increased usability and functionality of these devices combined with a proliferation of data driven applications has resulted in huge data consumption. This is confirmed with the data traffic on our network up around 25,000% over the last 5 years between 2007 and 2012.

Investing in Our Future…and Yours Evolving the network to provide you the best mobile Internet experience Investment >$98 billion invested in our wire line and wireless networks over the past five years (2008-2012) In 2012, invested nearly $20 billion, including more than 160,000 wireless network improvements Expect to invest in the range of $21 billion in 2013 In 2012, announced three year $14B investment plan with Project Velocity IP (2013-2015) To support increasing data consumption and continuing network evolution, AT&T continues to invest in our wireless network. -$98 billion wireline and wireless investment over the past five years, more than any other public company In 2012, we invested nearly $20 billion in our wired and wireless networks, including more than 160,000 wireless network improvements, including: (T-Mobile only $4B in 2012 http://online.wsj.com/article/SB10001424052970203918304577241042653586170.html) Added 766,000 Square Miles of 4G coverage Installed 849 Distributed Antenna Systems (public and enterprise) Deployed 81,000 new antennas Grew to more than 33,000 AT&T Wi-Fi Hot Spots in service Launched an initiative to deploy more than 10,000 macro sites, 1,000 distributed antenna systems Investment in our wireless and wireline networks is expected to be in the range of $21 billion in 2013, with about 60 percent of that to be spent on wireless. In late 2012, AT&T announced Project Velocity IP, which included plans to significantly expand and enhance our wireless and wireline IP broadband networks to support growing customer demand. As part of the investment plan, AT&T will boost capital spending by about 16 percent to $22 billion a year for the next three years to upgrade the wireless and wireline networks. AT&T's Project VIP consists of several initiatives, including: Enhance and expand wireline IP network to 57M customer locations, covering 75% of customer locations in wireline service area by YE 2015 Expand fiber network to reach an additional 1M business customer locations by YE 2015 And from a wireless perspective, initiatives include 1) 4G LTE expansion, with plans to expand to cover 300 million people by the end of 2014 Spectrum Densification & Small Cell Technology Wireless is our number one investment priority and we are working relentlessly to provide our customers with the most capacity, best coverage, and highest mobile Internet experience.

Now Available in 325 Markets The Nation’s Fastest 4G LTE Network Dual-layered 4G technologies for the best overall broadband experience Now Available in 325 Markets AT&T 4G LTE reaches more than 200 million people* More than double number of people covered in 2012 (vs. year-end 2011) Expect to cover 300M people by year-end 2014 4G network covers more than 292 million people Nation’s largest 4G network Virtually 100 percent of AT&T’s wireless network covered by HSPA+ Over 90 percent of mobile data traffic runs over enhanced backhaul Customers still have access to fast 4G speeds with HSPA+ when they go outside of a 4G LTE area AT&T delivers 4G using two complementary technologies — LTE and  HSPA+ with expanded backhaul – to deliver a widespread, ultra-fast and more consistent 4G experience. LTE: Deployed the nation’s fastest 4G LTE in 325 markets, reaching more than 200 million people. -More than double the number of people covered in 2012 vs. year-end 2011. -Plans to expand 4G LTE to 250 million people by year-end 2013 and to 300 million by year-end 2014. -AT&T LTE supports average data rates of 5-12 Mbps in the forward link, and 2-5 Mbps in the reverse link. -LTE technology also offers lower latency, or the processing time it takes to move data through the network. HSPA+: Complementing our 4G LTE network is HSPA+ with expanded backhaul, which enable 4G speeds. Typical download speeds range from approximately 2 Mbps up to 6 Mbps where AT&T has enhanced backhaul connections in place. Virtually 100 percent of AT&T’s wireless network is covered by HSPA+ We are rapidly expanding Ethernet and fiber to cell sites nationwide -- adding new cell sites weekly – and almost 90 percent of our mobile Internet traffic on expanded backhaul.  With LTE and HSPA+, AT&T has the nation’s largest 4G network covering more than 292 million people as well as the nation’s fastest 4G LTE network. As our 4G LTE footprint continues to grow, customers with compatible devices outside of 4G LTE areas will still have access to consistently fast mobile Internet speeds through HSPA+ for a widespread, ultra-fast and consistent 4G experience from AT&T. * Limited 4G LTE availability in select markets. 4G speeds are delivered by HSPA+ (with enhanced backhaul) or LTE, where available.

AT&T plans to begin deployment of LTE-Advanced in 2013 LTE - Advanced Advancing and Evolving the AT&T 4G Network Heterogeneous Network Topology Carrier Aggregation Higher peak data rates More efficient use of spectrum Increased number of simultaneously active subscribers Improved performance at the cell edge Features Advanced MIMO AT&T plans to begin deployment of LTE-Advanced in 2013 Carrier Aggregation increases transmission bandwidths in order to achieve very high data rates; allows operators to bond multiple downlink channels (different types of spectrum) to create higher throughput. Advanced MIMO (Multiple In/Multiple Out), a radio antenna technology that uses multiple antennas to increase capacity and improve range; instead of 2 antennas at each end there can be 4x4 or even 8x8. Heterogeneous Network Topology uses network intelligence to enable small cells and Wi-Fi hotspots to tightly integrate with the wider (macro) network without risk of interference. It also provides enhanced coverage and capacity and allows us to target capacity to demand. This combined network is commonly called a hetnet.

AT&T Antenna Solutions Augmenting Your Wireless Access Experience Providing you flexible network access methods for enhanced coverage AT&T Wi-Fi AT&T Antenna Solutions Nation’s largest Wi-Fi network* Deployed Wi-Fi hotzones with expansion plans 30K – plus domestic Hotspots Targeting locations that typically experience high- volume data usage with distributed antenna systems Wi-Fi AT&T has the nation’s largest Wi-Fi network* with more than 32,000 hotspots in the US, and access to nearly 402,000 hotspots globally through roaming agreements Virtually all new AT&T smartphones come equipped with Wi-Fi technology, and Wi-Fi use doesn’t count toward customers’ smartphone data plans. In addition, AT&T has deployed Wi-Fi hotzones to supplement mobile Internet in urban areas with consistently high mobile Internet use. Hotzones enhance the broadband experience for AT&T customers who use Wi-Fi enabled devices. Wi-Fi hotzones provide another fast and reliable way for customers to stay connected from their mobile devices, adding data network capacity in high traffic areas. AT&T deployed Wi-Fi hotzones in NYC’s Times Square, near Rockefeller Center, St. Patrick's Cathedral and along Park Avenue. Wi-Fi hotzones are also available in downtown Charlotte, N.C., Chicago’s Wrigleyville, downtown Indianapolis, San Francisco’s Embarcadero Center and in Silicon Valley on Palo Alto’s University Avenue AT&T plans to deploy additional hotzones in other urban areas across the country with consistently high data use AT&T also formed Antenna Solutions, which is charged with building antenna distribution systems in hundreds of large public venues around the country. The team is dedicated to delivering exceptional service to customers in locations that typically experience high-volume data usage, such as sporting events, concerts, and convention facilities to provide exceptional service *Largest based on branded and operated hotspots.
