AT&T’s Exaflood Acquisition Good for Mobile Consumers and Internet Growth

AT&T’s announced purchase of T-Mobile is an exaflood acquisition — a response to the overwhelming proliferation of mobile computers and multimedia content and thus network traffic. The iPhone, iPad, and other mobile devices are pushing networks to their limits, and AT&T literally could not build cell sites (and acquire spectrum) fast enough to meet demand for coverage, capacity, and quality. Buying rather than building new capacity improves service today (or nearly today) — not years from now. It’s a home run for the companies — and for consumers.

We’re nearing 300 million mobile subscribers in the U.S., and Strategy Analytics estimates by 2014 we’ll add an additional 60 million connected devices like tablets, kiosks, remote sensors, medical monitors, and cars. All this means more connectivity, more of the time, for more people. Mobile data traffic on AT&T’s network rocketed 8,000% in the last four years. Remember that just a decade ago there was essentially no wireless data traffic. It was all voice traffic. A few rudimentary text applications existed, but not much more. By year-end 2010, AT&T was carrying around 12 petabytes per month of mobile traffic alone. The company expects another 8 to 10-fold rise over the next five years, when its mobile traffic could reach 150 petabytes per month. (We projected this type of growth in a series of reports and articles over the last decade.)

The two companies’ networks and businesses are so complementary that AT&T thinks it can achieve $40 billion in cost savings. That’s more than the $39-billion deal price. Those huge efficiencies should help keep prices low in a market that already boasts the lowest prices in the world (just $0.04 per voice minute versus, say, $0.16 in Europe).

But those who focus only on the price of existing products (like voice minutes) and traditional metrics of “competition,” like how many national service providers there are, will miss the boat. Pushing voice prices down marginally from already low levels is not the paramount objective. Building fourth generation mobile multimedia networks is. Some wonder whether “consolidation of power could eventually lead to higher prices than consumers would otherwise see.” But “otherwise” assumes a future that isn’t going to happen. T-Mobile doesn’t have the spectrum or financial wherewithal to deploy a full 4G network. So the 4G networks of AT&T, Verizon, and Sprint (in addition to Clearwire and LightSquared) would have been competing against the 3G network of T-Mobile. A 3G network can’t compete on price with a 4G network because it can’t offer the same product. In many markets, inferior products can act as partial substitutes for more costly superior products. But in the digital world, next gen products are so much better and cheaper than the previous versions that older products quickly get left behind. Could T-Mobile have milked its 3G network serving mostly voice customers at bargain basement prices? Perhaps. But we already have a number of low-cost, bare-bones mobile voice providers.

The usual worries from the usual suspects in these merger battles go like this: First, assume a perfect market where all products are commodities, capacity is unlimited yet technology doesn’t change, and competitors are many. Then assume a drastic reduction in the number of competitors with no prospect of new market entrants. Then warn that prices could spike. It’s a story that may resemble some world, but not the one in which we live.

The merger’s boost to cell-site density is hugely important and should not be overlooked. Yes, we will simultaneously be deploying lots of new Wi-Fi nodes and femtocells (little mobile nodes in offices and homes), which help achieve greater coverage and capacity, but we still need more macrocells. AT&T’s acquisition will boost its total number of cell sites by 30%. In major markets like New York, San Francisco, and Chicago, the number of AT&T cell sites will grow by 25%-45%. In many areas, total capacity should double.

It’s not easy to build cell sites. You’ve got to find good locations, get local government approvals, acquire (or lease) the sites, plan the network, build the tower and network base station, connect it to your long-haul network with fiber-optic lines, and of course pay for it. In the last 20 years, the number of U.S. cell sites has grown from 5,000 to more than 250,000, but we still don’t have nearly enough. CEO Randall Stephenson says the T-Mobile purchase will achieve almost immediately a network expansion that would have taken five years through AT&T’s existing organic growth plan. Because of the nature of mobile traffic — i.e., it’s mobile and bandwidth is shared — the combination of the two networks should yield a more-than-linear increase in quality improvements. The increased cell-site density will give traffic planners much more flexibility to deliver high-capacity services than if the two companies operated separately.

The U.S. today has the most competitive mobile market in the world (second, perhaps, only to tiny Hong Kong). Yes, it’s true, even after the merger, the U.S. will still have a more “competitive” market than most. But “competition” is often not the most — or even a very — important metric in these fast moving markets. In periods of undershoot, where a technology is not good enough to meet demand on quantity or quality, you often need integration to optimize the interfaces and the overall experience, a la the hand-in-glove paring of the iPhone’s hardware, software, and network. Streaming a video to a tiny piece of plastic in your pocket moving at 60 miles per hour — with thousands of other devices competing for the same bandwidth — is not a commodity service. It’s very difficult. It requires millions of things across the network to go just right. These services often take heroic efforts and huge sums of capital just to make the systems work at all.

Over time technologies overshoot, markets modularize, and small price differences matter more. Products that seem inferior but which are “good enough” then begin to disrupt state-of-the art offerings. This was what happened to the voice minute market over the last 20 years. Voice-over-IP, which initially was just “good enough,” made voice into a commodity. Competition played a big part, though Moore’s law was the chief driver of falling prices. Now that voice is close to free (though still not good enough on many mobile links) and data is king, we see the need for more integration to meet the new challenges of the multimedia exaflood. It’s a never ending, dynamic cycle. (For much more on this view of technology markets, see Harvard Business School’s Clayton Christensen).

The merger will have its critics, but it seriously accelerates the coming of fourth generation mobile networks and the spread of broadband across America.

Data roaming mischief . . . Another pebble in the digital river?

Mobile communications is among the healthiest of U.S. industries. Through a time of economic peril and now merely uncertainty, mobile innovation hasn’t wavered. It’s been a too-rare bright spot. Huge amounts of infrastructure investment, wildly proliferating software apps, too many devices to count. If anything, the industry is moving so fast on so many fronts that we risk not keeping up with needed capacity.

Mobile, perhaps not coincidentally, has also been historically a quite lightly regulated industry. But emerging is a sort of slow boil of small but many rules, or proposed rules, that could threaten the sector’s success. I’m thinking of the “bill shock” proceeding, in which the FCC is looking at billing practices and various “remedies.” And the failure to settle the D block public safety spectrum issue in a timely manner. And now we have a group of  rural mobile providers who want the FCC to set prices in the data roaming market.

You remember that “roaming” is when service provider A pays provider B for access to B’s network so that A’s customers can get service when they are outside A’s service area, or where it has capacity constraints, or for redundancy. These roaming agreements are numerous and have always been privately negotiated. The system works fine.

But now a group of provider A’s, who may not want to build large amounts of new network capacity to meet rising demand for mobile data, like video, Facebook, Twitter, and app downloads, etc., want the FCC to mandate access to B’s networks at regulated prices. And in this case, the B’s have spent many tens of billions of dollars in spectrum and network equipment to provide fast data services, though even these investments can barely keep up with blazing demand.

The FCC has never regulated mobile phone rates, let alone data rates, let alone data roaming rates. And of course mobile voice and data rates have been dropping like rocks. These few rural providers are asking the FCC to step in where it hasn’t before. They are asking the FCC to impose old-time common carrier regulation in a modern competitive market – one in which the FCC has no authority to impose common carrier rules and prices.

In the chart above, we see U.S. info-tech investment in 2010 approached $500 billion. Communications equipment and structures (like cell phone towers) surpassed $105 billion. The fourth generation of mobile networks is just in its infancy. We will need to invest many tens of billions of dollars each year for the foreseeable future both to drive and accommodate Internet innovation, which spreads productivity enhancements and wealth across every sector in the economy.

It is perhaps not surprising that a small number of service providers who don’t invest as much in high-capacity networks might wish to gain artificially cheap access to the networks of the companies who invest tens of billions of dollars per year in their mobile networks alone. Who doesn’t like lower input prices? Who doesn’t like his competitors to do the heavy lifting and surf in his wake? But the also not surprising result of such a policy could be to reduce the amount that everyone invests in new networks. And this is simply an outcome the technology industry, and the entire country, cannot afford. The FCC itself has said that “broadband is the great infrastructure challenge of the early 21st century.”

Economist Michael Mandel has offered a useful analogy:

new regulations [are] like  tossing small pebbles into a stream. Each pebble by itself would have very little effect on the flow of the stream. But throw in enough small pebbles and you can make a very effective dam.

Why does this happen? The answer is that each pebble by itself is harmless. But each pebble, by diverting the water into an ever-smaller area,  creates a ‘negative externality’ that creates more turbulence and slows the water flow.

Similarly, apparently harmless regulations can create negative externalities that add up over time, by forcing companies to spending  time and energy meeting the new requirements. That reduces business flexibility and hurts innovation and growth.

It may be true that none of the proposed new rules for wireless could alone bring down the sector. But keep piling them up, and you can dangerously slow an important economic juggernaut. Price controls for data roaming are a terrible idea.

An Economic Solution to the D Block Dilemma

Last month, Cisco reported that wireless data traffic is growing faster than projected (up 159% in 2010 versus its estimate of 149%). YouTube illustrated the point with its own report that mobile views of its videos grew 3x last year to over 200 million per day. Tablets like the Apple iPad were part of the upside surprise.

The very success of smartphones, tablets, and all the new mobile form-factors fuels frustration. They are never fast enough. We always want more capacity, less latency, fewer dropped calls, and ubiquitous access. In a real sense, these are good problems to have. They reflect a fast-growing sector delivering huge value to consumers and businesses. Rapid growth, however, necessarily strains various nodes in the infrastructure. At some point, a lack of resources could stunt this upward spiral. And one of the most crucial resources is wireless spectrum.

There is broad support for opening vast swaths of underutilized airwaves — 300 megahertz (MHz) by 2015 and 500 MHz overall — but we first must dispose of one spectrum scuffle known as the “D block.” Several years ago in a previous spectrum auction, the FCC offered up 10 MHz for commercial use — with the proviso that the owner would have to share the spectrum with public safety users (police, fire, emergency) nationwide. This “D block” sat next to an additional 10 MHz known as Public Safety Broadband (PSB), which was granted outright to the public safety community. But the D block auction failed. Potential bidders could not reconcile the technical and business complexities of this “encumbered” spectrum. The FCC received just one D block bid for just $472 million, far below the FCC’s minimum acceptable bid of $1.3 billion. So today, three years after the failed auction and almost a decade after 9/11, we still have not resolved the public safety spectrum question. (more…)

More wireless connectivity? Or more politics?

For years we’ve been talking about the need for more wireless bandwidth, more spectrum, and a host of creative new strategies to complement our mobile phone networks — from familiar Wi-Fi to more exotic femtocells and satellites. The continuing explosion of mobile data traffic means we need these things now more than ever. In the graph below, Cisco projects 120% compound annual growth in North American mobile data from 2009 through 2013.

The Federal Communications Commission recognized these trends and needs in its new National Broadband Plan. It set the bold goal of unleashing 500 MHz of mostly dormant wireless spectrum for more productive use in new broadband Internet and media applications.

On March 29, the FCC had a chance to begin putting its Plan into action when it approved the acquisition of SkyTerra by Harbinger Capital. The result of the merger is a new wireless company that will use both MSS satellite spectrum and so-called ATC terrestrial spectrum to deliver a new hybrid mobile service. Harbinger announced it would build a nationwide, wholesale, “open access” 4G broadband wireless network at the cost of $6 billion. Although not part of the FCC’s 500 MHz push, the new Harbinger strategy aligns nicely with the goal of more, better, and broader wireless access and options throughout the country (in this case, Canada, too).

But the FCC order, which was not voted by the full commission but issued by the bureau chiefs, contains two curious provisions. The provisions restrict Harbinger’s cooperation with two important mobile service providers and could hinder the very goal of extending more wireless coverage to more Americans. (more…)

Lawyerpalooza

Larry Downes, author of the excellent Laws of Disruption and a new colleague at the Tech Liberation Front, notes the proliferation of patent lawsuits in the mobile phone world and points toward this good graphic in the New York Times to help make his point, that “It’s both much worse and not as bad as it seems”:

Mobile traffic to grow 39x by 2014

Cisco’s latest Visual Networking Index, this one focusing mobile data traffic, projects 108% compound growth through 2014.

Wireless Crunch

Adam Thierer makes important points about the wireless data boom . . . and the wireless spectrum crunch.

Did Cisco just blow $2.9 billion?

Cisco better hope wireless “net neutrality” does not happen. It just bought a company called Starent that helps wireless carriers manage the mobile exaflood.

See this partial description of Starent’s top product:

Intelligence at Work

Key to creating and delivering differentiat ed ser vices—and meeting subscriber demand—is the ST40’s ability to recognize different traffic flows, which allows it to shape and manage bandwidth, while interacting with applications to a very fine degree. The system does this through its session intelligence that utilizes deep packet inspection (DPI) technology, ser vice steering, and intelligent traffic control to dynamically monitor and control sessions on a per-subscriber/per-flow basis.

The ST40’s interaction with and understanding of key elements within the multimedia call—devices, applications, transport mechanisms, policies—and assists in the ser vice creation process by:

Providing a greater degree of information granularity and flexibility for billing, network planning, and usage trend analysis

Sharing information with external application ser vers that perform value-added processing

Exploiting user-specific attributes to launch unique applications on a per-subscriber basis

Extending mobility management information to non-mobility aware applications

Enabling policy, charging, and Quality of Ser vice (QoS) features

Traffic management. QoS. Deep Packet Inspection. Per service billing. Special features and products. Many of these technologies and features could be outlawed or curtailed under net neutrality. And the whole booming wireless arena could suffer.

Agreeing with Kessler

After challenging Andy Kessler over the Google Voice-Apple-AT&T dustup, I should point out some areas of agreement.

Andy writes:

Some might say it is time to rethink our national communications policy. But even that’s obsolete. I’d start with a simple idea. There is no such thing as voice or text or music or TV shows or video. They are all just data.

Right, all these markets and business models in hardware, software, and content — core network, edge network, data center, storage, content delivery, operating system, browser, local software, software as a service (SAS), professional content, amateur content, advertising, subscriptions, etc. — are fusing via the Internet. Or at least they overlap in so many areas and at any moment are on the verge of converging in others, that any attempt to parse them into discreet sectors to be regulated is mostly futile. By the time you make up new categories, the categories change.

Which naturally applies to one of the most contentious topics in Net policy:

Competition brings de facto network neutrality and open access (if you don’t like one service blocking apps, use another), thus one less set of artificial rules to be gamed.

Exactly. Net Neutrality could be an unworkably complex and rigid intrusion into this highly dynamic space. Better to let companies compete and evolve.

Kessler concludes:

Data is toxic to old communications and media pipes. Instead, data gains value as it hops around in the packets that make up the Internet structure. New services like Twitter don’t need to file with the FCC.

And new features for apps like Google Voice are only limited by the imagination.

The Internet is disrupting communications companies. Although yesterday I defended the service providers, who are also the key investors in all-important Net infrastructure, it is true their legacy business models are under assault from the inexorable forces of quantum technologies. Web video assaults the cable companies’ discrete channel line-ups. Big bandwidth banished “long distance” voice and, as Kessler says, will continue disrupting voice calling plans. On the other hand, the robust latency and jitter requirements of voice and video, and the realities of cybersecurity will continue to modify the generalized principle that bits are bits.

Even if we can see where things are going — more openness, more modularity, more “bits are bits” — we can’t for the most part mandate these things by law. We have to let them happen. And in many cases, as with the Apple-AT&T iPhone, it was an integrated offering (the exclusive handset arrangement) that yielded an unprecedented unleashing of a new modular mobile phone arena. Those 100,000 new “apps” and a new, open Web-based mobile computing model. Integration and modularity are in constant tension and flux, building off one another, pulling and pushing on one another. Neither can claim ultimate virtue. We have to let them slug it out.

As I wrote yesterday, innovation yin and yang.

Innovation Yin and Yang

There are two key mistakes in the public policy arena that we don’t talk enough about. They are two apparently opposite sides of the same fallacious coin.

Call the first fallacy “innovation blindness.” In this case, policy makers can’t see the way new technologies or ideas might affect, say, the future cost of health care, or the environment. The result is a narrow focus on today’s problems rather than tomorrow’s opportunities. The orientation toward the problem often exacerbates it by closing off innovations that could transcend the issue altogether.

The second fallacy is “innovation assumption.” Here, the mistake is taking innovation for granted. Assume the new technology will come along even if we block experimentation. Assume the entrepreneur will start the new business, build the new facility, launch the new product, or hire new people even if we make it impossibly expensive or risky for her to do so. Assume the other guy’s business is a utility while you are the one innovating, so he should give you his product at cost — or for free — while you need profits to reinvest and grow.

Reversing these two mistakes yields the more fruitful path. We should base policy on the likely scenario of future innovation and growth. But then we have to actually allow and encourage the innovation to occur.

All this sprung to mind as I read Andy Kessler’s article, “Why AT&T Killed Google Voice.” For one thing, Google Voice isn’t dead . . . but let’s start at the beginning.

Kessler is a successful investor, an insightful author, and a witty columnist. I enjoy seeing him each year at the Gilder/Forbes Telecosm Conference, where he delights the crowd with fast-paced, humorous commentaries on finance and technology. Here, however, Kessler falls prey to the innovation assumption fallacy.

Kessler argues that Google Voice, a new unified messaging application that combines all your phone numbers into one and can do conference calls and call transcripts, is going to overturn the entire world of telecom. Then he argues that Apple and AT&T attempted to kill Google Voice by blocking it as an “app” on Apple’s iPhone App Store. Why? Because Google Voice, according to Kessler, can do everything the telecom companies and Apple can do — better, even. These big, slow, old companies felt threatened to their core and are attempting to stifle an innovation that could put them out of business. We need new regulations to level the playing field.

Whoa. Wait a minute.

Google Voice seems like a nice product, but it is largely a call-forwarding system. I’ve already had call forwarding, simultaneous ring, Web-based voice mail, and other unified messaging features for five years. Good stuff. Maybe Google Voice will be the best of its kind.

There are just all sorts of fun and productive things happening all across the space. It was the very AT&T-Apple-iPhone combo that created “visual voice mail,” which allowed you to see and choose individual messages instead of wading through long queues of unwanted recordings.

But let’s move on to think about much larger issues.

Suggesting we can enjoy Google’s software innovations without the network innovations of AT&T, Verizon, and hundreds of service providers and technology suppliers is like saying that once Microsoft came along we no longer needed Intel. (more…)

Biting the handsets that connect the world

Over the July 4 weekend, relatives and friends kept asking me: Which mobile phone should I buy? There are so many choices.

I told them I love my iPhone, but all kinds of new devices from BlackBerries and Samsungs to Palm’s new Pre make strong showings, and the less well-known HTC, one of the biggest innovators of the last couple years, is churning out cool phones across the price-point and capability spectrum. Several days before, on Wednesday, July 1, I had made a mid-afternoon stop at the local Apple store. It was packed. A short line formed at the entrance where a salesperson was taking names on a clipboard. After 15 minutes of browsing, it was my turn to talk to a salesman, and I asked: “Why is the store so crowded? Some special event?”

“Nope,” he answered. “This is pretty normal for a Wednesday afternoon, especially since the iPhone 3G S release.”

So, to set the scene: The retail stores of Apple Inc., a company not even in the mobile phone business two short years ago, are jammed with people craving iPhones and other networked computing devices. And competing choices from a dozen other major mobile device companies are proliferating and leapfrogging each other technologically so fast as to give consumers headaches.

But amid this avalanche of innovative alternatives, we hear today that:

The Department of Justice has begun looking into whether large U.S. telecommunications companies such as AT&T Inc. and Verizon Communications Inc. are abusing the market power they have amassed in recent years . . . .

. . . The review is expected to cover all areas from land-line voice and broadband service to wireless.

One area that might be explored is whether big wireless carriers are hurting smaller rivals by locking up popular phones through exclusive agreements with handset makers. Lawmakers and regulators have raised questions about deals such as AT&T’s exclusive right to provide service for Apple Inc.’s iPhone in the U.S. . . .

The department also may review whether telecom carriers are unduly restricting the types of services other companies can offer on their networks . . . .

On what planet are these Justice Department lawyers living?

Most certainly not the planet where consumer wireless bandwidth rocketed by a factor of 542 (or 54,200%) over the last eight years. The chart below, taken from our new research, shows that by 2008, U.S. consumer wireless bandwidth — a good proxy for the power of the average citizen to communicate using mobile devices — grew to 325 terabits per second from just 600 gigabits per second in 2000. This 500-fold bandwidth expansion enabled true mobile computing, changed industries and cultures, and connected billions across the globe. Perhaps the biggest winners in this wireless boom were low-income Americans, and their counterparts worldwide, who gained access to the Internet’s riches for the first time.

total-us-wireless-bandwidth-2000-08

Meanwhile, Sen. Herb Kohl of Wisconsin is egging on Justice and the FCC with a long letter full of complaints right out of the 1950s. He warns of consolidation and stagnation in the dynamic, splintering communications sector; of dangerous exclusive handset deals even as mobile computers are perhaps the world’s leading example of innovative diversity; and of rising prices as communications costs plummet.

Kohl cautioned in particular that text message prices are rising and could severely hurt wireless consumers. But this complaint does not square with the numbers: the top two U.S. mobile phone carriers now transmit more than 200 billion text messages per calendar quarter.

It’s clear: consumers love paid text messaging despite similar applications like email, Skype calling, and instant messaging (IM, or chat) that are mostly free. A couple weeks ago I was asking a family babysitter about the latest teenage trends in text messaging and mobile devices, and I noted that I’d just seen highlights on SportsCenter of the National Texting Championship. Yes, you heard right. A 15 year old girl from Iowa, who had only been texting for eight months, won the speed texting contest and a prize of $50,000. I told the babysitter that ESPN reported this young Iowan used a crazy sounding 14,000 texts per month. “Wow, that’s a lot,” the babysitter said. “I only do 8,000 a month.”

I laughed. Only eight thousand.

In any case, Sen. Kohl’s complaint of a supposed rise in per text message pricing from $.10 to $.20 is mostly irrelevant. Few people pay these per text prices. A quick scan of the latest plans of one carrier, AT&T, shows three offerings: 200 texts for $5.00; 1500 texts for $15.00; or unlimited texts for $20. These plans correspond to per text prices, respectively, of 2.5 cents, 1 cent, and, in the case of our 8,000 text teen, just .25 cents. Not anywhere close to 20 cents.

The criticism of exclusive handset deals — like the one between AT&T and Apple’s iPhone or Sprint and Palm’s new Pre — is bizarre. Apple wasn’t even in the mobile business two years ago. And after its Treo success several years ago, Palm, originally a maker of PDAs (remember those?), had fallen far behind. Remember, too, that RIM’s popular BlackBerry devices were, until recently, just email machines. Then there is Amazon, who created a whole new business and publishing model with its wireless Kindle book- and Web-reader that runs on the Sprint mobile network. These four companies made cooperative deals with service providers to help them launch risky products into an intensely competitive market with longtime global standouts like Nokia, Motorola, Samsung, LG, Sanyo, SonyEricsson, and others.

As The Wall Street Journal noted today:

More than 30 devices have been introduced to compete with the iPhone since its debut in 2007. The fact that one carrier has an exclusive has forced other companies to find partners and innovate. In response, the price of the iPhone has steadily fallen. The earliest iPhones cost more than $500; last month, Apple introduced a $99 model.

If this is a market malfunction, let’s have more of them. Isn’t Washington busy enough re-ordering the rest of the economy?

These new devices, with their high-resolution screens, fast processors, and substantial 3G mobile and Wi-Fi connections to the cloud have launched a new era in Web computing. The iPhone now boasts more than 50,000 applications, mostly written by third-party developers and downloadable in seconds. Far from closing off consumer choice, the mobile phone business has never been remotely as open, modular, and dynamic.

There is no reason why 260 million U.S. mobile customers should be blocked from this onslaught of innovation in a futile attempt to protect a few small wireless service providers who might not — at this very moment — have access to every new device in the world, but who will no doubt tomorrow be offering a range of similar devices that all far eclipse the most powerful and popular device from just a year or two ago.

Bandwidth Boom: Measuring Communications Capacity

See our new paper estimating the growth of consumer bandwidth – or our capacity to communicate – from 2000 to 2008. We found:

  • a huge 5,400% increase in residential bandwidth;
  • an astounding 54,200% boom in wireless bandwidth; and
  • an almost 100-fold increase in total consumer bandwidth

us-consumer-bandwidth-2000-08-res-wireless

U.S. consumer bandwidth at the end of 2008 totaled more than 717 terabits per second, yielding, on a per capita basis, almost 2.4 megabits per second of communications power.

Web 3.0

Could the iPhone 3.0 release this summer help create the mechanism — and culture — of micro-payments that many have long been seeking to solve the Web’s intellectual property problem?

UPDATE: These guys were thinking the exact same thing.

Wireless wonders

As the wireless world continues to churn out terrific new hardware and software innovations and network speeds, Engadget talks about the industry in depth with AT&T’s wireless chief Ralph de la Vega.
