AT&T 4G LTE Expands In Phoenix

More customers to benefit from ultra-fast mobile Internet on the latest LTE devices

PHOENIX, Dec. 18, 2012 /PRNewswire/ -- AT&T* has expanded its 4G LTE network in Phoenix, bringing more customers the latest generation of wireless network technology. AT&T launched 4G LTE in Phoenix on January 5, 2012, and the expanded coverage is part of its ongoing rollout across the market.


AT&T 4G LTE coverage now includes parts of Chandler, Gilbert and Queen Creek

Watch here to see several of the benefits AT&T 4G LTE provides, including:

  • Faster speeds. LTE technology is capable of delivering mobile Internet speeds up to 10 times faster than 3G. Customers can stream, download, upload and game faster than ever before.
  • Cool new devices. AT&T offers several LTE-compatible devices, including new AT&T 4G LTE smartphones and tablets, such as the Sony Xperia™ TL, LG Optimus G™, Samsung Galaxy S III, Motorola ATRIX™ HD, HTC One™ X, Nokia Lumia 900, Samsung Galaxy Note™ II, HTC One™ X+, Samsung ATIV smart PC and ASUS VivoTab™ RT.
  • Faster response time. LTE technology offers lower latency, or the processing time it takes to move data through a network, such as how long it takes to start downloading a webpage or file once you've sent the request. Lower latency helps to improve services like mobile gaming, two-way video calling and telemedicine.
  • More efficient use of spectrum. Wireless spectrum is a finite resource, and LTE uses spectrum more efficiently than other technologies, creating more space to carry data traffic and services and to deliver a better network experience.

"We've seen positive response from customers on our 4G LTE launch, and as today's expansion shows, we're continuing our rollout of fast 4G LTE speeds to more areas of Phoenix," said Jerry Fuentes, president of AT&T Arizona and New Mexico. "Consumers are asking for more from the technology they use in their daily lives, and we are investing to meet and exceed their needs."

AT&T invested more than $500 million in its Arizona wireless and wireline networks from 2009 through 2011 with a focus on improving the company's mobile Internet coverage and overall performance of its networks.

AT&T's 4G Network

AT&T's innovation and investment has 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.** 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.

Even as AT&T continues to expand its 4G LTE coverage, customers can get 4G speeds outside of 4G LTE areas on our 4G HSPA+ network, unlike competitors, where smartphone customers fall back to slower 3G technologies when outside of LTE coverage.

AT&T's focus to deliver the best possible mobile Internet experience goes beyond 4G 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.

AT&T also is a leading developer of Distributed Antenna Systems, which utilize multiple small antennas to maximize coverage and speed within stadiums, convention centers, office buildings, hotels and other areas where traditional coverage methods are challenging. 

Over the past five years, AT&T invested more than $115 billion 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 public company. In a July 2012 report, the Progressive Policy Institute ranked AT&T No. 1 on its list of U.S. "Investment Heroes."

You have your devices and your data, but what about the rest of your Internet of Things story? Two popular classes of technologies that nicely handle the Big Data analytics for Internet of Things are Apache Hadoop and NoSQL. Hadoop is designed for parallelizing analytical work across many servers and is ideal for the massive data volumes you create with IoT devices. NoSQL databases such as Apache HBase are ideal for storing and retrieving IoT data as “time series data.”
Clearly the way forward is to move to cloud be it bare metal, VMs or containers. One aspect of the current public clouds that is slowing this cloud migration is cloud lock-in. Every cloud vendor is trying to make it very difficult to move out once a customer has chosen their cloud.

As-a-service models offer huge opportunities, but also complicate security. It may seem that the easiest way to migrate to a new architectural model is to let others, experts in their field, do the work. This has given rise to many as-a-service models throughout the industry and across the entire technology stack, from software to infrastructure. While this has unlocked huge opportunities to accelerate the deployment of new capabilities or increase economic efficiencies within an organization, i...
