MiFi: What's the point?

By most accounts, MiFi is getting a warm end user reception. Novatel Wireless, which makes the MiFi, posted a third-quarter profit, reversing last year's loss, as strong sales of its MiFi personal Wi-Fi hotspot. Novatel recently surprised Wall Street analysts by revealing it had received $100 million in orders for the MiFi in the first two months.

Novatel executives think the MiFi could be a new product category someplace between a dongle and a smartphone. That remains to be seen, as consumers ultimately will decide what the value is, and how big the value is.

The MiFi creates a mobile, personal hotspot for up to five devices using a single 3G connection. For some, it might be a more-convenient dongle or aircard for PCs. If so, the difference might turn on such simple issues as whether a device that requires use of a USB port is less functional than a device that doesn't require use of a port.

For others, the advantages will be the ability to connect devices without USB ports to a Wi-Fi network.  Dual-mode smartphones might provide one example, but they probably don't provide the biggest obvious benefit, especially when those smartphones have 3G connections.

More obvious value will be garnered by users of iPod "Touch" or other devices that operate only on Wi-Fi, not mobile broadband, and who already pay for a 3G connection, in any location other than the home or office.

Perhaps the more obvious application is a temporary Wi-Fi hotspot for business users in a workgroup setting. But I'd be willing to be that is only one of many uses consumers will find for the MiFi.

For some, the only additional required value might be the ability to use their 3G access device without tying up a USB port. For others it is the ability to access the Internet from their Wi-Fi devices wherever they can get a 3G signal, without needing separate 3G connections for each discrete device.

The point is that hard dollar savings will drive the value for some users, while for others it might be something as simple as "not tying up a USB port." Along the way, clever users will figure out other ways why a MiFi connection adds more value for a mobile broadband connection than using an aircard or dongle.

Quantifying the Carrier Wi-Fi Hotspot Business Model

Customer retention--not direct customer fees--might be the biggest part of the carrier public hotspot busimess model, says Stephen Rayment, CTO, BelAir Networks.

"Churn reduction is where lots of the value is," is Rayment. Assume churn per month of two percent a month, which means a typical customer provides 50 months of revenue, he says.

Adding metro hotspot access can provide a 10 percent churn reduction, he adds. Assume the 10 percent churn benefit on a typical subscriber relationship of 50 months, meaning the typical account now remains active for 55 months. Assume a typical customer average revenue per user of $130 a month.

That suggests an extra $650 of subscriber revenue over the length of a relationship. For a service provider with 100,000 subscribers that works out to $65 million in extra revenue.

If the average customer value is $2,000 per customer, and that service provider can use public hotspot service to reduce churn 10 percent, it adds about $200 per subscriber in terms of equity value.

For a service provider with one million subscribers, that's $200 million in incremental equity revenue.

For a service provider with one million subs, making an investment of $40 million to cover all the high-traffic spots, there is a five-to-one return on investment.

There arguably could be other revenue contributors as well, though none likely approaches the value of enhanced retention. There might be an opportunity for a small amount of additional revenue. Some customers will be willing to be stand-alone hotspot subscriptions.

Service providers might make some money from other carriers by offering hotspot access to customers roaming into the local area. There could be some advertising upside or some commercial upside from providing services to public utilities or public safety organizations, he says.

Some service providers also might look at public Wi-Fi as a way to add some mobility features to their landline service.

Mobile providers also likely will find public hotspots a useful way to offload traffic from the 3G and 4G networks to the fixed network, Rayment says.

"The networks are just choking" because of heavy new smartphone traffic, says Rayment. "People really did not see this until the iPhone, but 3 in the U.K. market also saw skyrocketing demand when it started selling the iPhone," says Rayment.

Up to this point, aircards and dongles used for mobile PC connections have been driving new bandwidth demand on the 3G and WiMAX networks. But that is changing. "Dongles drove the initial demand, but will be overtaken by the smartphone," he says.

Pingo Launches Smartphone-Based Global Calling Service

Pingo, the prepaid international calling service from iBasis, now has released a smartphone application enabling simple international calling from a wide variety of smartphones, including the iPhone, Blackberry, Treo and phones using operating systems such as Nokia Symbian, Windows Mobile and Google Android.

"Pingo EZ Dial" automatically syncs with the mobile's address book, so dialing happens the way it always does, but the Pingo client recognizes that an international number is being called and routes the call using the Pingo network.

EZ Dial users don’t dial access numbers, PIN codes or change their calling behavior in any way and does not require users to connect to Wi-Fi. Users will consume domestic or local airtime minutes of use, but incur no global calling charges from their mobile provider.

Users go to the Pingo Web site (http://www.pingo.com) to sign up for a prepaid account. Users of iPhone devices can download the client for free from the Applie App Store. Users of other phones simply enter a phone number and Pingo sends out a text message with a hot link that initiates the over-the-air client download.

Pingo thinks the move is important since more calls are being initiated from mobile handsets these days, so more global calling also is being initiated from handsets.

Users with feature phones can get the same low rates, but will have to dial a local access number, since those phones cannot download the EZ Dial client.

All of that will change as Long Term Evolution or WiMAX networks become more ubiquitous, since all devices operating on those networks will be data devices able to download clients.

In many ways, the Pingo mobile calling capability is a reflection of the broader shift to mobile-originated and terminated calling. Pingo long has been a huge supplier of white label wholesale services to other retail providers, and most of those providers were wired network providers.

Since the U.S. market is by far one of the largest global markets in the world, mobile support is important for any company that makes a living from international voice traffic. Also, mobile origination is more important in the U.S. market, since the ratio of origination to termiantion is about three to one outbound compared to inbound, says Jayesh Patel, iBasis VP. "Most countries don't have that sort of  imbalance."

Recently, iBasis has noted more use of its calling plans by business users as well, so EZ Dial is offered in a business account version that allows easier administrative setup and call tracking.

Verizon Droid Launches Today

Verizon Wireless has launched two Android-powered smartphones Nov. 6, 2009. At the top, the much-anticipated Droid retails at $199.99 and is the first Android smartphone to feature the version 2.0 platform.

But Verizon also launched a second Droid-branded device, called Eris and manufactured by HTC. Eris will retail at $99.99.

A successful launch is regarded by many as critical to Motorola's future success, as the company attempts to regain market share.

Verizon also launched a number of other handsets, including the new BlackBerry Curve 8530 (already offered by Sprint), a new LG Chocolate device, and Samsung's Push-To-Talk Convoy.

Droid will the most-important launch, for several reasons. The success of its Android phones is crucial for Motorola if it is to climb back into the top ranks of handset manufacturers. It would be fair at this point to say Android is a "do or die" move for Motorola.

For HTC, the device is less important than the fact that HTC now is trying to build its own brand name, growing beyond its contract manufacturing roots.

People Don't Buy Smartphones, They Buy the Experience and the Feeling

All engineering involves choices, and that is true of all smartphone design as well.

Perhaps one of the background pressures is the desire to create devices that perform reasonably across a range of functions.

But that might not be a formula for success. A recent study by Interpret might suggest that instead of balancing features, it might be better to "unbalance" and produce a device that is demonstrably better at one thing.

Though one can argue we are early in the adoption cycle, a panel of consumers indicated that the Palm Pre made them feel "smart," "trendy, hop or cool," and "productive" within some range of acceptance for a smartphone device.

The problem would seem to be that Pre scores highest on the emotional attribute that users say is least important of the top three. The Pre produces emotions on the "hip" and "productive" scale that make it analogous to the BlackBerry Storm.

The bigger problem is that the Pre does not produce unusually high key emotions on any of the top three most important measures smartphone buyers say are important to them. BlackBerry and iPhone probably are the best models. Each of them scores unusually high on at least one of the three key emotional drivers smartphone buyers say motivate them.

So maybe designers should forget "balance." So far, no single smartphone unit scores unusually high on the "it makes me feel smart" measure. The iPhone owns the "hip, cool, trendy" space. The BlackBerry owns the "it makes me feel productive" niche.

Smartphones are bought because of the "feelings" they produce, not the features they provide. As the saying goes, smartphones "sell an experience."

Consumer Behavior in Recession was as Expected

Time Warner Cable's third quarter results provide a bit of concrete evidence that consumers did what they said they were going to as far as watching their spending on communications and entertainment services because of the recession.

Consumers said earlier in 2009 they were least likely to cut or reduce spending on Internet access and most likely to cut back on buying pay-per-view movies downloaded over the Internet, according to a new survey by Alcatel-Lucent. But mobile service, basic entertainment video service and telephone lines were among the items consumers said they were most likely to keep, though cutting back on things such as going to night clubs and concerts or going out to movies and restaurants.

All of those patterns would be in keeping with past consumer behavior in recessions.

(see http://ipcarrier.blogspot.com/2009/06/network-services-generally-safe-but.html, http://www.blogger.com/post-edit.g?blogID=7312392900566055630&postID=5497830666217750659)

Generally speaking, people said they would be keeping their broadband Internet, wireless and video entertainment services, though showing much more willingness to curtail adding new enhanced or premium services.

Some surveys suggested consumers would accelerate their abandonment of wired voice, while others suggested demand for fixed telephone services would hold up.

Time Warner Cable's results show that broadband Internet additions held up as expected, though sales of digital video, a premium upgrade, fell, as consumers suggested would be the case.

Time Warner's new voice customers also appear weak, though that bit of data does not necessarily confirm analyst expectations. Existing customers of other voice services might simply have stuck with their existing providers instead of switching to Time Warner Cable.

Overall net new additions tend to show the impact of consumer caution. The company added 117,000 revenue generating units in the third quarter, compared to 522,000 a year ago.

More to the point, Time Warner added 8,000 net new digital video customers, compared to 56,000 net new subscribers analysts were expecting. It added 62,000 net new voice customers where analysts had expected 107,000. The firm also added 117,000 broadband Internet access customers, where analysts had expected 115,000.

So broadband held up, while digital video activity fell, as did voice services.

Still, there are lots of variables to consider. Local market competitive conditions can sharply affect results, as do promotional activities.

Comcast, for example, saw its digital video customer base grow a net 7.4 percent, while adding 6.4 percent net new broadband customers and 20.3 percent voice customers.

Still, the point is that consumers had suggested, and history suggested, that wireless, broadband Internet and entertainment video growth rates would slow, but that the services themselves would hold up. It appears they did, at least for these two large cable operators. At&T and Verizon also added large numbers of wireless customers, as well as a decent number of video and broadband access customers.

Marketers Sell to Mobile Users, Not Subs

There are times when counting things one way, compared to a slightly different way, yield results that largely are the same. But for mobile marketers, counting mobile "subscribers" and "mobile users" will produce distinct results that do matter. 

The differences are that "subscriptions" are not equal to "users" because some users have multiple subscriptions. If you usse a mobile broadband card or dongle, plus two cell phones, you have three mobile subscriptions, for example. 

Mobile marketers want to reach people, not devices or subscriptions, so the method of counting makes a difference. In Europe, for example, many studies show mobile penetration to be at or in excess of 100 percent, but that is because many users have multiple subscriber information modules, each of which has a phone number, and counts as a subscription, even when only one SIM is in active use at any time. 

For marketers, the number of mobile users is a more useful figure because it more accurately describes the audience, and thus potential reach.

So how big is the actual U.S. mobile audience? Reserchers at eMarketer estimate that mobile penetration of users is 76.5 percent in 2009, or 235 million people,  rising gradually to 255.4 million in 2013, or 80 percent penetration.

By way of comparison, subscriber fgures from CTIA – The Wireless Association show there aer 276.61 million mobile subscriptions in service as of June 2009. That would work out to about 90 percent penetration of people. 

That 13-percent difference might not make a great deal of practical difference, except that the difference in estimates means the potential reach of any mobile marketing campaign might potentially reach 41.6 million fewer people. 

In the context of a mobile campaign that might not be so crucial, especially when marketers target one specific device or one specific carrier. But the difference in potential reach could be quite large for any campaign that tries to reach most users, and will certainly be reflected in the cost of any campaign. 

Droid Tethering in 2010

Though users apparently will not have the option immediately, Verizon Wireless says users of its Droid smartphones eventually will be able to use their Droids as a "dongle" to connect notebooks. The tethering capability apparently will cost an additional $15 to $50 a month above the normal data plan, depending on the usage plan any specific user already has, but will most often be an additional $30 a month.

The tethering feature will not be available until 2010, Verizon says.

Some end users are sure to complain about the additional fees, but Verizon Wireless has a sizable and growing business selling dongle access for notebooks and is understandably not anxious to cannibalize that business by allowing Droids and other smartphones to act as dongles.

Basically, the additional $30 fee makes the Droid a dongle as used with Verizon's "Mobile Broadband" service, costing $40 a month if all a user expects to use is 250 MBytes or less. The $60 monthly plan includes 5 Gbytes of usage.

Every user will have to figure out how much data they actually need to use in a month, but the tethering option will provide value for most users who need a Droid data plan and some amount of mobile broadband access for their netbooks or notebooks. If you need to use both your smartphone and your PC for Internet access parts of every month, and your combined usage from both devices does not exceed 5 Gbytes a month, that access, using tethering, costs $60 a month.

Separately, the 5 Gbyte plan and Droid data plan would cost $90 a month. On the other hand, separate data plans also means separate buckets of usage, so the value of one's choices depends on how much total usage one expects to require in a typical month.

Under most circumstances, a consumer user will find a single 5-Gbyte mobile bucket is reasonable for tethered and smartphone use. Traveling business users, expecting to use the Droid as a dongle for work purposes every month, might not find the tethering option quite so workable.

Consumers who really watch a lot of video on their PCs and mobiles will need to be quite careful about the tethering option. In that case an unlimited smartphone data plan likely is best.

Wi-Fi's Business Model: Not What Was Expected

New technologies sometimes wind up being used in ways not originally envisioned. It might sound odd today, but there was a time when public Wi-Fi was seen by some as a replacement for fixed broadband used by residential customers, or as a competitor to wireless 3G networks.

These days, with a couple of notable exceptions, public Wi-Fi lives by indirect revenue models. It is an amenity for retail or hospitality operations that make money some other way. Coffee, food, lodging or memberships are some of the revenue models.

The notable exception is "for fee" Wi-Fi in global markets where the cost of 3G access is very high, making a for-fee Wi-Fi connection a better deal.

In recent years, the typical revenue model for public Wi-Fi has been that it is a valuable amenity for sales of fixed broadband connections and retention of customers. More recently, public Wi-Fi has become an important component of the value of some smartphones, which can use hotspots for VoIP even when it is not allowed on the 3G networks.

AT&T, for example, says that its customers made 25.4 million Wi-Fi connections in the third quarter of 2009, exceeding the 20 million connections made in all of 2008 and nearly equaling the 25.6 million connections made in the first half of 2009.

Wi-Fi usage has been increasing significantly each quarter, up from 5.2 million connections in the third quarter of 2008. Smartphones and other Wi-Fi enabled devices are the reason, AT&T says.

For the first time, the number of Wi-Fi connections made by smartphones and other mobile devices in the third quarter surpassed connections from laptops, AT&T notes.

About 60 percent of all AT&T Wi-Fi connections were made from mobile devices, up from 49 percent in the second quarter of 2009, AT&T says.

Public Wi-Fi seems destined to play a bigger role in the smartphone market going forward, as it is a great way to offload video and other bandwidth-intensive applications from the mobile network to the fixed network.

So aside from its value as a feature that supports an indirect revenue model for retailers, it is a value-enhancing way for service providers to differentiate and add value to their mobile and fixed broadband services.

In the future, it likely will assume a greater role in allowing mobile networks to better manage bandwidth. None of those initially were thought of as the "value" of public Wi-Fi.

Amazon Integrates Twitter

It increasingly looks as though Twitter's business model will rely, in large part, on marketing services of various types.

A recent study by professors at Penn State University found that 20 percent of tweets contain requests for product information or responses to the requests, says Jim Jansen, associate professor of information science and technology in the College of Information Sciences and Technology at Penn State.

Separately, Amazon.com has introduced a new feature that allows Amazon Associate members to broadcast links to Amazon products via their Twitter accounts.

Amazon Associates is the partner program the company uses as part of its affiliate advertising programs, allowing customers to make money advertising Amazon products.

Associates can now simply click a link in the toolbar to send a link and text to Twitter as part of their shopping and selling experience. Amazon gets a sale, Twitter gets traffic, and the associate gets revenue share.

Smartphones are Changing the Wi-Fi Hotspot Business

Smartphones are changing the nature of the hotspot business, it now appears. Originally envisioned as a way to provide "outside the home" and "outside the office" connections for laptop and notebook PC users, hotspots now are becoming important sources of broadband connections for smartphones.

One example: iPass, which used to focus on managing PC authentication processes for traveling enterprise workers, now finds it is focusing more attention on managing authentication processes for enterprise smartphones, says Rick Bilodeau iPass VP.

"Smartphones are the new thing," he says. "Now it is smartphones and Blackberries." The software is available for BlackBerry, Symbian and iPhone at the moment, and iPass is watching the Android, though it hasn't seen enterprise demand for that device yet.

As a firm that manages broadband access for hundreds of Fortune 2000 companies, iPass has to manage connections created on hundreds of global networks, but now scores of smartphone devices as well.

To make that process easier, it created an "Open Device Framework," a standardized interface to iPass client software that allows enterprises to write their own XML scripts for the specific dongles, phones and other devices they want to support.

The company also now preconfigures Mi-Fi routers, loading SSID information directly into the boxes before they are delivered to their users, for example. The iPass log-on software also can be preloaded. "We're first to do this, we think," says Bilodeau.

ODF is available now and the Mi-Fi featuers will be available in December 2009, he says.

BlackBerry and iPhone Users are Different, Just Not Wildly So

BlackBerry users are different from iPhone users, a new study by Retrevo Gadgetology suggests. Some of the differences are amusing, perhaps intentionally so, as the questions asked of younger BlackBerry and iPhone users included some that observers might find frivolous, or intended to evoke humorous responses.

Apple iPhone say they find cool gadgets, “most attractive,” about a person, in fact, three times more than they find a college degree attractive.

BlackBerry owners think a college degree is more attractive than the mobile device they use.

About 34 percent of iPhone owners and 29 percent of BlackBerry owners think old gadgets on a potential partner are a turn off. Some 33 percent of iPhone owners say they have broken up with someone  using text messaging, compared to 22 percent of BlackBerry users.

A quarter of iPhone users say they have broken off a relationship because their partner spent too much time on their mobile, compared to 17 percent of BlackBerry users.

The Retrevo Gadgetology report surveyed 445 iPhone and BlackBerry owners distributed across gender, age, income and location in the United States.

"Surprising" AT&T Stance on Net Neutrality?

Some people might be shocked to learn that AT&T complies with existing Federal Communications Commission rules. Some people might be shocked to learn that AT&T actually already agrees that "best effort" Internet services ought to treat every packet the same as every other.

“We use the principle of ‘us on us,’” says AT&T  CTO John Donovan. “If we take an external developer and ourselves, we should not be advantaged in how long it takes or how much expertise is required."

"I don’t think it needs to be that complicated," he says. Does any application run by any third party work as well on the network as an AT&T-provided application?

"Outside applications need to be on an equal footing with our own applications," Donovan says.

But that's part of the problem with net neutrality. It is very hard to define and covers a range of business discrimination issues, network management and performance practices as well as potential future services that consumers might very well want to buy, that provide value precisely because they allow users to specify which of their applications take priority when the network is congested.

As a working definition, net neutrality is the idea that ISPs cannot "discriminate" between packets based on the owner or sender of packets, or on the type of lawful application, or block lawful packets.

The latter principle already applies to fixed broadband access connections, and the new change might be the extension of such rules to wireless providers. What is "new" in the current net neutrality debate is that concept that no packet can be afforded expedited handling, compared to another.

At some level, this is common sense. One wouldn't want video packets or voice packets sold by a third party to be disadvantaged, compared to video packets sold by the Internet access provider, for example.

But that isn't the issue in the current round of discussions and the possible FCC rulemaking. The issue is more an issue of  whether "affirmative" packet handling, as opposed to "negative" packet handling, will be lawful in the future.

"Negative" packet handling is sort of a "thou shalt not" approach: application providers should have a reasonable expectation that their best-effort Internet traffic will be handled the same way as any other application provider's traffic is treated. So ISPs "shalt not" provide any quality-of-experience advantage for their own application bits, as compared to any other bits delivered over the network.

All that sounds fair and reasonable, and in fact ISPs (after a few notable cases of interference), have concluded it is not worth the public outrage to block or delay any packets to heavy users, even when networks are congested, for the purpose of maintaining overall user experience for all the other users.

But there are several issues here. Good public policy would forbid business discrimination, a situation where any ISP could attempt to favor its own applications over those provided by its competitors. Back in the "old days," an example might have been a refusal by one telephone company to deliver calls from a rival.

But the network neutrality debate is far more complicated than that. There is a broad area where network management policies designed to maintain performance might be construed as business discrimination, even when the purpose is simply to protect 95 percent of users from heavy demand created by five percent of users.

Under heavy load, real-time applications such as video and voice suffer the most. So either end users might want, or ISPs might prefer, to give priority to those sorts of applications, at peak load, and slow down packets less sensitive to delay.

The problem with crudely-crafted net neutrality rules is that they might make illegal such efforts to maintain overall network performance for most applications and most users. One can hope that will not be the result, but it remains a danger.

The other issue is creation of new services or applications that can take advantage of expedited handling. Users might want their video or voice packets to have highest priority when there is network congestion. Crude net neutrality rules might make that impossible. But one can hope policymakers will take that sort of thing into consideration.

Net neutrality is a very-complicated issue with multiple facets. Ironically, end users might, in some cases, actually want packet discrimination.

More U.K. Mobile than Fixed Broadband Users in 2011?

More people will use mobile broadband rather than fixed line broadband by 2011, mobileSquared predicts. It's the sort of shocking prediction that makes for a great headline, but also is misleading. The forecast, for the U.K. market, might lead one to conclude that users are disconnecting fixed broadband lines and using mobile instead.

But that is not what the forecast assumes. Rather, it primarily assumes continued growth of smartphone connections.

By 2011 the number of active 3G "smartphone" type devices in the UK will be 36.3 million. There also will be 6.4 million dongles and embedded devices in use, taking the total number of mobile broadband connections to 42.7 million compared to a base of fixed broadband connections of 42.5 million, mobile Squared projects.

To be sure, over time there will be more Internet access occuring from broadband-capable smartphones.
The firm estimates that between one percent and 10 percent of enterprise Internet traffic is already being generated from a mobile device, for example.

But most observers, and most users, likely would say that mobile broadband and fixed broadband are complementary, more than substitutes.

That noted, the application profile for mobile broadband likely will be distinctive. “Mobile will become the primary access point for brands and businesses communicating with its consumers within two years,” says Nick Lane, mobileSquared chief analyst. “Mobile is always-on, and the average user carries their device for an average of 16 hours a day. So if a company or brand is not already considering how to use mobile, then they need to because their customers are.”

As the typical mobile "phone" becomes a multi-purpose broadband device, it will be used for Internet applications. That is not to say the typical smartphone will replace a PC, or a fixed broadband connection. The application profile and mode of use will start to overlap. But each mode will retain key advantages for the bulk of usage. People will talk more on their mobile phones than on their PCs.

They will engage in research, document, calculation or process intensive operations, plus most long-form TV, on a PC or a notebook equipped for broadband access. But people will rely increasingly on their mobiles for social networking updates, location-related apps, real-time information and brief entertainment episodes, and sometimes for long-form video.

The point is that mobile broadband now consists of two distinct segments: smartphones and PC dongles. And while both overlap at times with fixed broadband, they are distinct. Wireless broadband used to connect PCs generally is a complement to fixed broadband access, not a substitute, though that will happen at times.

So the mobileSqured forecast, which essentially lumps all smartphone data accounts with PC dongle accounts to reach the conclusion that mobile broadband will be a bigger business than fixed broadband, is correct in one sense, but wrong in another. In fact, all forms of broadband access are increasing.

Order of Magnitude Increase in Mobile Bandwidth by 2015

U.S. mobile carrier traffic reach 724 TBytes per month in 2015, up from 15 TB per month in 2009, says Coda Research Consultancy, an overall compound annual growth rate of 90 percent. As you might expect, video is behind the sharp rise, growing 104 percent.

(click image for larger view)

In fact, by 2015, video is forecast to represent about two thirds of all traffic, or 459 TB a month, Coda Research says.

That could be a problem. Sprint and Clearwire, for example, argue their new WiMAX networks will provide three times to five times the bandwidth of 3G networks. That's all well and good, but this forecast suggests aggregate demand will grow 10 times from present levels.

Several issues: is there enough spectrum to handle all this growth? What is the cost of upgrading facilities, even if there is enough spectrum? Is there any video revenue model that pays for the investments? Will the mobile regulatory framework provide incentives or disincentives for investment?

Those are the big challenges. But the report has other nuggets for some parts of the mobile ecosystem.

Handsets will drive 68 percent of mobile carrier traffic by 2015, while netbooks will represent 14 percent.
Coda also estimates that mobile ad revenues will total $5.05 billion in 2015.

By 2015, mobile data revenue will grow to 47 percent of mobile service provider revenues, while voice generates 53 percent of revenue. This last prediction is important, as it suggests how and when mobile service providers will cope with the ultimate shift away from mobile voice business models.
