Video and Web Drive Mobile Bandwidth Consumption

Mobile bandwidth demand already is driven by video and Web access, a new analysis by Allot shows (click on image for larger view).

And though peer-to-peer applications were the cause of bandwidth fears several years ago, most video activity now occurs using HTTP, meaning it is now part of the Web browser experience.

As is true for backbone networks and fixed networks, voice, instant messaging, email and all other apps besides video and Web applications are a negligible driver of bandwidth consumption.

That doesn't mean revenue reflects bandwidth use. Revenue still is inordinately driven by voice and texting. Over time, that will change. If broadband is what is driving use of the network, then broadband has to become the mainstay of the revenue model as well.

Multiple Tools Needed to Preserve Mobile Bandwidth

Chetan Sharma Consulting forecasts that if left unchecked, the costs of delivering mobile data will likely outstrip incremental revenues by the second half of 2011 in the U.S. market and become unsustainable by 2013.

The rapid growth in mobile data costs has prompted operators to look at more sophisticated network congestion management strategies that fall into four categories: policy control, data traffic offload, infrastructure investment, and network optimization.

Shifting data traffic off a congested mobile network and onto another access technology fundamentally changes the economics of delivering that data. Offload is being implemented by operators globally, including offload to Wi-Fi and offload to femtocells.

Operators deploying a mixed multi-access offload strategy can expect savings in the range of 20 to 25 per cent per year. In the US market, operators will save between $30 and $40 billion per annum by 2013 through an offload strategy alone.

More-efficient new networks will help as well. Infrastructure evolution to 3.5G (HSPA) and 4G (LTE ) lowers the cost-per-bit for data throughput on the network, thereby reducing overall costs.

Chetan Sharma Consulting forecasts that evolving to HSPA and LTE will result in cost savings of just under 20 per cent or almost $25 billion per year in the U.S. market by 2013.

Network optimisation, through techniques such as compression and caching also adds incremental
savings by reducing the total number of bits traversing the network. Typically, Sharma reports,
operators can generate savings of five to 10 per cent by 2013 through this strategy.

Anecdotally, operators have reported that 80 per cent of the traffic in urban centers is being
generated by 10 per cent of the cell sites. So policy control (how, when and under which circumstances subscribers can access networks) can contribute annual cost savings of over 10 per cent, equating to over $15 billion in annual cost reduction by 2013 in the US market, Chetan Sharma says.

But cost reduction is only one side of the equation. Tiered and usage-based pricing also is required. Such policies need not be heavyhanded, top-down service provider rules but rather flexible, dynamic, and personalised pricing models that reflect subscribers’ preferences and context.

Taken as a whole, all the optimization techniques and new pricing models will be needed as the whole mobile business changes from a voice revenue model to an "bandwidth-based" business.

Social Networking Drives Mobile Web Activities

Without much fanfare, social networking has become a "killer app" for the mobile Web use by smartphone or feature phone users.

Or at least that is what one would surmise based on recent data from GroundTruth, which shows that more than 60 percent of U.S. mobile Web page views are to social networking sites.

A separate study by the GSM Association shows that in December 2009, about half the time they actually were using their mobile Internet access, U.K. mobile users accessing the Internet from their mobiles were going to Facebook.

So far, social networking is developing as the killer app for mobile broadband.

In 2014, 80% of Broadband Access Will Be Mobile, says Huawei

By 2014, 80 percent of the world's two billion broadband users will be using mobile networks for their access, says Huawei. Of those two billion users, 1.5 billion will be first-time subscribers.

Predictions such as that are one reason regulators and suppliers need to be much more cognizant of how much is changing in the global communications business. Policies that relate to broadband access and deployment must reorient to reflect user behavior and supply that will be overwhelmingly mobility-based in just a few years.

Huawei also points out that voice services revenues also are steadily declining."In the past five years, the revenue for fixed voice services decreased by 15 percent, reflected by a decreasing growth rate for mobile voice services in 2009," Huawei says.

If that is a fundamental trend, as Huawei believes it is, then policies cannot be designed on the assumption that voice revenues, traditionally the underpinning for the whole global business, will continue to do so in the future.

In other words, instead of assuming service providers are powerful gatekeepers who need to be restrained, it might be more apt to view them as endangered suppliers who must replace the bulk of their revenues over the next decade or so, simply to remain in business. That certainly is not how telecom companies have been viewed in the past, but to ignore the changes could be dangerous.

U.S. regulators were so intent on introducing more competition in voice services in the early 1990s that they nearly completely missed the fact that the Internet, broadband and over-the-top applications and services were about to change the industry. Basically, the intended market result was to cause incumbents to lose market share while competitors were to gain share, precisely at the point that nearly every competitor was about to face a declining market for voice services.

It takes little insight to observe that a narrow focus on fixed broadband might likewise be dangerous at a time when usage is shifting so profoundly to mobile modes.

To use an analogy, regulators must resist the temptation to "fight the last war," rather than the different new war that is coming.

Mobile Broadband Prices: As Usage Climbs, Something's Gotta Give

Sooner or later, mobile broadband consumption patterns are going to force mobile Internet service providers to better match consumption with usage, for the simple reason that the cost of supplying end user bandwidth probably will grow faster than the cost of infrastructure, on a per-megabit-per-second basis, will drop.

That obviously affects the mobile broadband business case, especially if video comes to represent 90 percent of all bandwidth demand, as Cisco now predicts and as global backbone networks already demonstrate.

At the current average traffic levels of 500 MBytes a month, revenue per MByte outstrips delivery costs for HSPA, LTE and WiMAX at monthly retail prices starting at $20 per month, says Monica Paolini, Senza Fili Consulting president.

At $20 per month, mobile operators operate at a loss for subscribers using more than 1 GByte per month in a 3G network, or for subscribers using more than 5 GBytes per month on a 4G network, Paolini says.

At 10 GBytes per month, data subscribers do not generate any net benefit for mobile operators on a 3G network. On a 4G network 10 GBytes of usage might be a break-even proposition.

Apple iPad Will Use AT&T 3G Network

Apple's new iPad will use Wi-Fi and also AT&T's 3G wireless network. Users can opt for using Wi-Fi only, as iTouch users do, or can buy 3G service. AT&T offers a 250-megabyte plan for $15 a month, and an unlimited plan for $30, neither requiring a contract.

Those pricing levels more closely resemble an iPhone data plan than a data card subscription, which costs $60 a month, and typically requires a contract.

Some observers might say the iPad subscriptions represent a "higher-quality" or higher-margin revenue source than is typical for iPhone subscriptions, which also represent $30 a month in fees, because AT&T gets the traffic without having to factor in a subsidy for the devices.

One issue is how much data iPad users will consume. Users of the iPhone typically consume about 400 megabytes a month, where mobile PC card users tend to consumer about 2 gigabytes a month. A reasonable estimate is that iPad usage will fall somewhere between those levels.

More Regulation Needed to Spur Broadband Competition? Really?

The U.S. Federal Communications Commission should consider regulations for broadband providers in an effort to increase competition, says Lawrence Strickling, National Telecommunications and Information Administrationassistant secretary, as reported by IDG News Service.

"We urge the Commission to examine what in many areas of the country is at best a duopoly market and to consider what, if any, level of regulation may be appropriate to govern the behavior of duopolists," Strickling says.

With all due respect for Strickling, who is a smart, experienced regulatory type who knows the terrain, and without disagreeing in full with the full content of his filing on behalf of NTIA, the notion that competition somehow is so stunted that new regulatiions are required likely would lead to greater harm, despite its good intentions.

Here's the argument. Consider, if you will, any large industry with critical implications for the entire U.S. economy. Now consider the following mandate: "you will be forced to replace 50 percent of your entire revenue in 10 years."

"During that time, for a variety of reasons, incumbents will be forced to surrender significant market share to competitors, so that in addition to replacing half of the industry's revenue, it also will have to do so with dramatically fewer customers."

"After that, in another decade, the industry will be required to replace, again, another 50 percent of its revenue. All together, the industry will required to relinquish at least 30 percent of its market share, in some cases as much as half, and also will be required to replace nearly 100 percent of its revenue, including the main drivers of its profitability."

Does that sound like the sort of industry that desperately needs additional competition? Really?

Nor is the argument theoretical. Over a 10-year period between 1997 and 2007, the U.S. telephone industry was so beset with new technology and competition that almost precisly half of its revenue (long distance), the revenue driver that provided nearly all its actual profit, was lost.

The good news is that the revenue was replaced by wireless voice. Then, because of the Internet, cable company entry into voice and the Telecommunications Act of 1996, market share began to wither. That, after all, is the point of deregulation: incumbents are supposed to lose market share to competitors.

Now we have the second decade's project, when mobile voice revenues similarly will have to be replaced, in turn, as IP-based voice undermines the high-margin voice services that have been the mainstay of the mobile business.

If you follow the telecom industry as a financial matter, you know that service providers have maintained their profitability only partly by growing topline revenues. They also have been downsizing workforces and slashing operating costs.

If you talk to ex-employees of the telecom industry, they will tell you the industry seems no longer to be a "growth" industry. That's why millions of people who used to work in telecom no longer do so.

So what about the other big incumbent industry, cable TV operators. As you clearly can see, and can read about nearly every day, there are huge questions about the future business model for what used to be known as "cable TV." Many observers already predict that such services will move to Internet delivery, weakening or destroying the profitability of the U.S. cable industry.

Industry executives, no dummies they, already have moved into consumer voice and data communications, and now are ramping up their assault on business communications. Why? They are going in reverse for the core video business.

Imposing regulatory burdens on incumbents--either telco or cable--that are losing their core revenue drivers on such a scale might not be wise. Few industries would survive back-to-back decades where the core revenue drivers must be replaced by "something else."

Imagine the U.S. Treasury being asked to replace virtually 100 percent of its revenue with "something else" in about 20 years. Imagine virtually any other industry being asked to do the same.

The point is that industries asked to confront such challenges and surmount them are not typically the sort of industries that need to have additional serious obstacles placed in their way.

Granted, they are niche suppliers, but Strickling also is well aware there are two satellite broadband providers battling for customers, plus five mobile broadband providers, and then hundreds of independent providers providing terrestrial fixed wireless access or packaging wholesale capacity to provide retail services.

Granted, only cable, satellite, telcos and several mobile providers have anything like ubiquitous footprints, but that is a function of the capital intensity of the business. Most markets will not support more than several suppliers in either fixed or wireless segments of the business.

One can argue there is not more facilities-based competition because regulation is inadequate, or one can argue investment capital no longer can be raised to build a third ubiquitous wired network.

The point is that wired network scarcity might be a functional of rational assessments of likely payback. Cable TV franchises are not a monopoly in any U.S. community. But only rarely have third providers other than the cable TV or incumbent phone companies attempted to build city-wide third networks. Regulatory barriers are not the issue: capital and business potential are the problems.

Also I would grant that mobile broadband is not a full product substitute for fixed broadband. But where we might be in five to 10 years cannot yet be ascertained. And we certainly do not want to make the same mistake we made last time.

The Telecommunications Act of 1996, the first major revamping of U.S. telecom regulation since 1934, was supposed to shake up the sleepy phone business. But the Telecom Act of 1996 occurred just as landline voice was fading, and the Internet was rising.

If you wonder why virtually every human being with a long enough memory would say their access to applications, services, features and reasonable prices is much better now than before the Telecom Act of 1996, even assuming it has completely failed, the answer is that the technology and the market moved too fast for regulators to keep up.

The Telecom Act tried to remedy a problem that fast is becoming irrelevant: namely competition for voice services. In fact, voice services rapidly are becoming largely irrelevant, or marginal, as the key revenue drivers for most providers in the business.

Yes, there are only a few ubiquitous wired or wireless networks able to provider broadband. But that might be a function of the capital required to build such networks, the nature of payback in a fiercely-competitive market and a shift of potential revenue away from "network access" suppliers and towards application providers.

It always sounds good to call for more competition. Sometimes it even is the right thing to do. But there are other times when markets actually cannot support much more competition than already exists. Two to three fixed broadband networks in a market, plus two satellite broadband providers, plus four to five mobile providers, plus many smaller fixed wireless or reseller providers does not sound much like a "market" that needs to stimulate more competition.

There's another line of reasoning one might take, but would make for a very-long post. That argument would be that, judged simply on its own merits, the availability and quality of broadband services, in a continent-sized country such as the United States, with its varigated population density, is about what one would expect.

Even proponents of better broadband service in the United States are beginning to recognize that "availability" is not the problem: "demand" for the product is the key issue.

E-Book Style Revenue Models Needed for Many Mobile Devices

As Apple plans to introduce a new mobile "tablet" device, and rumors grow that Google is working on a Chrome operating system tablet of its own, it is not hard to predict that much future growth for mobile service providers will be in providing broadband data connections for such devices, whether or not the actual first-generation devices from Apple and Google actually take off.

The reasons are drop-dead simple: most people who want a mobile phone already have one. The new growth frontier is for other devices that also benefit from a broadband connection, such as notebooks, tablets and e-book readers.

Shipments of mobile broadband-enabled consumer electronics are forecast to increase 55-fold between 2008 and 2014, say researchers at ABI Research. The market includes e-book readers, mobile digital cameras and camcorders, personal media players, personal navigation devices and mobile gaming devices. Total global shipments reach 58 million in 2014, says ABI Research.

One suspects sales of mobile-connected devices will hit critical mass only when a device is linked intimately with a content service that provides the revenue model. Not many consumers likely will spend much money to Internet-enable their cameras, for example.

Instead, what we probably will need to see are content services (e-book readers provide an excellent example) where payment for content subsidizes the use of mobile broadband access, with no incremental cost to the end user.

One suspects tablet devices likewise will achieve only modest success until video and other content services provide the revenue to support no-incremental-cost use of mobile broadband connectivity.

It isn't immediately clear how this might work for devices supporting multi-player gaming, for example, but e-book style models likely will have to be created for mass adoption of mobile broadband for gaming devices.

Consumers are not going to want to buy subscription plans for many discrete mobile devices at rates anywhere close to what broadband access now costs, either for smartphones or notebooks, for example.

64% of U.S. Broadband Connections Now are Mobile

There are more mobile broadband subscriptions in service in the U.S. market than fixed line.

The CTIA notes that there are now 103 million mobile broadband customers in the United States, according to Informa Telecom and Media. There are more than 58 million fixed line subscribers, according to Insight Research Corp.

By that measure, there are 161 million U.S. broadband subscriptions. So mobile connections represent 64 percent of broadband connections now in use. And mobile broadband has exploded over the last 18 months.

In June 2008, mobile broadband accounted for more than 59 million high speed subscribers, about 45 percent of all broadband connection in the United States, according to the Federal Communications Commission.

Clearly, any effort to create a national U.S. broadband policy would have to recognize the leading role wireless now plays.

Wi-Fi Hotspot Market Increasingly Provides "Mobile Offload"

Some proponents once touted Wi-Fi hotspots as an alternative to mobile or out-of-home broadband service. It increasingly look as though the Wi-Fi hotspot is emerging as a way of offloading traffic from the mobile network, as well as a way of supporting mobile devices that do not have data plans.

In-Stat estimates that hotspot usage will increase in 2009 by 47 percent, bringing total worldwide connects to 1.2 billion.

“Mobile operators have become increasingly involved in the hotspot market globally as they assess the potential of hotspots to offload wireless data traffic from overburdened 3G networks," says says Frank Dickson, In-Stat analyst.

Also, mass market adoption of Wi-Fi-enabled smartphones has significantly altered hotspot usage, with these devices accounting for the majority of access sessions in some locations,” he says.

Total worldwide hotspot venues will reach 245,000 locations in 2009, while AT&T is on course to experience 500 percent usage growth, year over year, In-Stat notes.

Users Say They Want ISPs Offering Both Wireless and Fixed Broadband

There are some heartening implications for service providers able to offer both mobile and fixed broadband access, and disturbing implications for providers who do not have such capabilities, in a new survey of 1,000 consumers conducted by the Yankee Group.

Specifically, more than 60 percent of survey respondents indicate a strong interest in mobile Internet, and 45 percent state that for their next broadband purchase they will choose an ISP that offers mobile service.

Mobile Broadband Complementary to Fixed Broadband

Over the next three to five years, mobile broadband will be complementary to fixed broadband, rather than a substitute, says William Lehr, economist and research associate in the Computer Science and Artificial Intelligence Laboratory at Massachusetts Institute of Technology.

"I expect fixed and mobile broadband services to offer distinctly different sets of basic capabilities, and as a consequence, to remain distinct services that will not be perceived as close substitutes in most user and usage contexts for the foreseeable future," Lehr says.

There will be situations where it is reasonable to expect that mobile services will be perceived as substitutes, if imperfect substitutes, for fixed connections, and will therefore result in some cannibalization, he says.

Users who are more budget conscious (the young or others with limited incomes, for example) are more likely to choose one instead of both services, Lehr suggests.

Heavy users may prefer fixed broadband access, while light users (or those who live alone) may find the mobile alternative more appealing.

Also, users who place a high value on mobility are more likely to opt for mobile over fixed services. Conversely, those whose principal mode of usage is at a fixed location and who would have a high need for a large sized display, may strictly prefer fixed broadband services.

As mobile data rates increase, some users may find that for their usage profile, mobile is fast enough to meet their needs even for shared household use. That should especially be true now that MiFi devices can allow sharing of one mobile connection by as many as five devices.

On the other hand, even though mobile bandwidth is increasing, so is fixed bandwidth. So the relative value of mobile over fixed services is greater when the fixed service is less capable. In other words, a fast 4G wireless connection might be perceived as superior to a lower-speed digital subscriber line connection, compared to a fiber-to-home connection or DOCSIS 3.0 cable modem service.

What the situation might be in 10 years is likely unknowable, but it is reasonable enough to assume that if today's smartphones are simply tomorrow's phones, and if new devices continue to be developed, that mobile broadband always will be a distinctly complementary service. If you assume today's 276 million mobile phone users in the future will simply be smartphone users with broadband connections, you get the point.

In fact, it probably makes more sense to say that fixed services are not going to be substitutes for mobile broadband, than to argue that mobile will be a substitute for fixed access. Nearly every mobile device will require broadband, irrespective of what in-home or in-office devices require.

Whatever you think about mobile broadband, it is worth remembering that mobile broadband services were not available in the U.S. market until 2005. So we are at this point just five years into the product's lifecycle.

By the first quarter of 2008, 40 million or almost 16 percent of mobile subscribers were regularly accessing the Internet using mobile broadband services, according to Nielsen.

Analysts at Forrester Research use a lower figure of 34 million subscribers in 2008. That will have grown at a 52 percent rate in 2009 to 52 million, and mobile broadband will continue to exhibit double-digit growth through 2014, when 106 million users, or a full 39 percent of all wireless subscribers, will become regular mobile Internet users, Forrester now projects.

PC data cards represent about 34 percent of mobile broadband subscriptions, while smartphones rapidly have emerged as the key driver of new mobile broadband accounts.

T-Mobile USA Moves to 7.2 Mbps, Plans 21 Mbps

There are times when being late to market is actually a benefit. The latest entrants in any technology-based market have access to the latest technology, and can build their business plans around that fact. There are other times when it's a bit difficult to characterize a particular competitor's position.

That is where T-Mobile USA now sits, for example. T-Mobile USA was the last of the top-four U.S. mobile providers to build a 3G network, and it has uncertain plans for 4G. But the company is on track to have faster versions of 3G up and running before some of its major competitors.

The company had no 3G customers in the second quarter 2008, though it had acquired 3G spectrum. But the 3G network now covers 240 cities and passes 170 million people, with plans to extend coverage to 200 million people by the end of 2009, at which point nearly all major urban areas will be covered.

So here's where the "last shall be first" principle applies.T-Mobile is using the faster 7.2 HSPA air interface, running at 7.2 Mbps downstream, on all its 3G nodes by the end of 2009.

At least one of T-Mobile's primary competitors is upgrading less-capacious 3.6 HSPA networks to 7.2 HSPA, but will not have that conversion completed until the end of 2011.

Likewise, T-Mobile plans to upgrade even the 7.2 HSPA network to HSPA+, a 21 Mbps network. The company says it will start rolling out HSPA+ in 2010. T-Mobile says the upgrade will be a relatively low-cost and relatively easy upgrade.

Of course, the reason T-Mobile's position is complex is that it has not yet announced a specific method for deploying a 4G network, which will require additional spectrum.

Both AT&T and Verizon are building their 4G networks for substantial coverage by 2010, while AT&T will have substantial coverage in 2011. Sprint is banking on the Clearwire network for 4G.

Still, competition in the mobile broadband market might not primarily be about "feeds and speeds." Coverage, pricing, application stores and device exclusivity arguably are more important.

Nor is it yet entirely clear that 4G will offer an entirely new consumer marketing proposition, beyond "faster." European 3G networks languished for years with sluggish uptake because the compelling new services requiring a 3G network were not in place.

In the U.S. market, it has been the mobile Web that has driven an upsurge of 3G uptake. But that adoption was based in part on applications and capabilitiesm, in part on use of particular devices, which require use of the 3G network.

The question for 4G networks is what new value or application will drive uptake.

Perhaps no new discrete driver will be required. Maybe "more" will be sufficient. But as Verizon has so far discovered with its FiOS fiber to the home feature, consumers still need a reason to buy fiber access as compared to hybrid fiber-copper access.

Providers can be last or first. Either way, the applications and device capabilities will remain the drivers of adoption.

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.

The point is that the business model for public hotspot networks frequently is indirect.

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.

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

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.

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.

Kindle Connections Now Go to AT&T

In a business with true scale and scope economies, ownership of a global network can be a key advantage. Consider network support for the Amazon Kindle book readers, which now are sold internationally.

The U.S. version of the Kindle 2 has used the Sprint 3G network. But both international and U.S. versions will henceforth use the AT&T network globally. Existing U.S. Kindle owners will continue to use Sprint, but all new devices will be powered by the AT&T network.

Of course, there are other ebook readers. Barnes & Nobles sells the Nook, Sony sells the Daily Edition and Plastic Logic sells the Que. All of those readers use AT&T's network.

Verizon will provide service for the upcoming iRex e-reader.

The financial impact to Sprint might be a relatively minor issue. Sanford Bernstein analyst Craig Moffett estimates the Kindle will drive one million Kindle users a year to AT&T that Sprint would otherwise have gotten.

Moffett estimates that Sprint makes about $5 for each subscriber addition and $2 per every e-book downloaded onto Kindle over its networks, according to Business Week writer Olga Kharif.

The real issue is whether other upcoming devices and services have enough of a global angle, and enough sales volume, that providers such as Sprint are unable to compete in those new lines of business as well.

Mobile Broadband PC Data Card Growth Decelerates

Mobile broadband PC card accounts continued to grow in the fourth quarter of 2008, but at a much-reduced rate compared to the prior six quarters, researchers at comScore say. But it is a product that continues to have an enviable growth pattern.

PC data card adoption grew 163 percent overall in 2008, slightly ahead of the 157 percent growth rate in 2007. However, despite this rapid adoption curve, fourth-quarter growth showed the first signs of decelerating growth. On a quarter over quarter basis, the subscriber growth fell to just five percent, following sequential growth of 22 percent in the third quarter of 2008.

One can speculate about the reasons for the slower growth rate, but one obvious explanation is a deceleration of employment, reducing the number of users whose consumption is subsidized by their employers. Add to the that the slowing economy, and one probably has all the explanation one requires.

Consumer users might also be choosing to access the mobile Web using their smart phones, as a data plan already is required, and the logic of paying for another subscription plan to access the Internet and Web applications probably is unattractive.
