GSM Association Embraces "One Voice"

The GSM Association has adopted the "One Voice Initiative" as a way of delivering voice and messaging services for fourth-generation Long-Term Evolution (LTE) services. One Voice is based on IP Multimedia Subsystems and will provide a standard for voice and text messaging interconnection and international roaming on 4G networks, just as carriers now support 2G and 3G interworking.

The GSMA’s Voice over LTE (VoLTE) initiative has the backing of more than 40 organizations from across the mobile ecosystem.

Mobile operators supporting the initiative include 3 Group, AT&T, Bell Canada, China Mobile, Deutsche Telekom/T-Mobile, KDDI, mobilkom austria, MTS, NTT DoCoMo, Orange, SKT, SoftBank, Telecom Italia, Telecom New Zealand, Telefónica, Telenor, TeliaSonera, Verizon Wireless and Vodafone.

Handset manufacturers and equipment vendors supporting the initiative include Acme Packet, Alcatel-Lucent, Aylus, Camiant, Cisco, Colibra, Communigate, Comneon, Ericsson, Fujitsu, Genband, Huawei, LG, Motorola, Movial, Mu, NEC, Nokia, Nokia Siemens Networks, Qualcomm, RADVISION, Samsung, Sony Ericsson and Tekelec.

The Trouble with WiMAX


The "trouble" with WiMAX, I've maintained, has nothing to do with performance, or necessarily with network cost. The technology will work. The issue is how and where WiMAX fits in the business environment. In developed markets where lots of competition already exists, the issue is figuring out where WiMAX plays in the applications environment. As a fixed alternative to cable modem, fiber-to-customer or Digital Subscriber Line services, the issue is how big a market exists. As a mobile broadband platform, the issue is how it competes with 3G networks and Long Term Evolution, the GSM-based fourth generation network alternative.

There's less contention in rural areas or less-developed broadband environments. Where it is too expensive to deploy a terrestrial broadband network, WiMAX has a clear logic. Even there, though, there might be questions about how more-established mobile voice and 3G networks factor into the competitive equation. One certainly can argue that WiMAX will provide much more bandwidth than 3G, today. The issue is how long it will take to create robust revenue models for 3G services, let alone providing those services more effectively over a faster 4G network.

It is, in short, a business issue, not a technology issue. To be sure, one can argue that a new market for broadband-enabled devices other than mobile phones is coming to fruition. But the issue there remains whether WiMAX necessarily or primarily provides access to those devices in ways that 3G cannot, let alone 4G. One might argue that WiMAX has a shot at providing access to all kinds of consumer devices other than "phones." But one might also argue that such connectivity has to be much cheaper than anything we've seen so far.

WiMAX networks might be half as costly as a 3G network to build. But that's not enough. They also have to be less than half as costly to operate, or prices won't be low enough to entice users to pay for connections to cameras, music players, game or entertainment platforms, for example. Those functions also are enabled on 3G networks, in many cases, combining the text and voice functions with the very services WiMAX might enable.

WiMAX might not prove to have the market traction its supporters hope for, in other words, at least in developed broadband markets where there is robust competition from cable modem, DSL, fiber to home, 3G mobile, fixed wireless, Wi-Fi hotspot and satellite broadband alternatives. The difference could come if WiMAX becomes the mobile provider 4G platform or if mobile WiMAX access is priced well below current mobile rates, allowing customers to access enable more devices than they now do.

It is not unthinkable for users to consider simultaneous broadband subscriptions. But it does require a more-compelling value/price relationship. We can assume standard-issue mobile phones, increasingly of the "smart" variety and optimized for Web experiences. We also can assume greater penetration of wireless data cards to support notebook PC use in nomadic fashion. What is not yet clear is the potential demand for broadband-connected music players, cameras, game players, dedicated navigation devices or video players. How many different subscriptions are users willing to pay for?

There is some thinking that WiMAX will be used especially heavily by mobile PC customers, as WiMAX is seen as powering a good chunk of the access card business.

“In 2010, the forecasted WiMAX subscriptions in North America will represent two percent of that for mobile 2.5G/3G and 66 percent of the subscriptions for mobile data cards,” say Philip Marshall, Yankee Group vice president, and Tara Howard, Yankee Group analyst.

Yankee Group estimates the number of WiMAX subscribers will increase from 1.3 million to 7.8 million between 2006 and 2011 and that in 2011, 7 million subscribers will be using 802.16e technology. Some percentage of that use will be for fixed broadband access, of course.

Assume such forecasts are correct. The percentage of WiMAX subscribers relative to residential broadband subscribers in the North American market then will increase from 2.2 percent to 7.4 percent between 2006 and 2010. Whatever else one might say about this level of adoption, it certainly doesn’t represent some sort of full-blown challenge to cable modem, DSL or fiber-to-customer access technologies. In fact, WiMAX, if it is adopted as Yankee Group researchers now forecast, will be yet another ancillary or niche form of broadband access.

So in mature markets, the major upside opportunity for WiMAX is expected with mobile personal broadband services, with fixed and portable services gaining moderate early market traction. In some Asian markets, such as Korea, it is conceivable that WiMAX-based mobile broadband could succeed, despite the existence of robust 3G and mobile video alternatives.

Still, the ultimate role of WiMAX in the wireless market is debatable, says a recent Organization for Economic Cooperation and Development report. “Large supporters such as Intel have a vision that WiMAX will change the way we all access the Internet in a matter of years,” says the report.

“Detractors claim that the economics of large-scale WiMAX networks are simply not justified,” the OECD report suggests.

Mobile WiMAX technologies may have the most profound impact in some urban areas because they could fill a connectivity void between 3G data networks and Wi-Fi, though.

Ultimately, this will not be a matter of technology, but of commercial issues and creation of new niches. It's hard to see GSM mobile operators going with WiMAX as a full-blown replacement for 3G, when LTE is coming. And it isn't simply a matter of technical performance. Smooth migration paths are important for large carriers. WiMAX might be too abrupt a transition for many. That might not be the case in undeveloped broadband markets, where a fixed broadband capability is reason enough to deploy it. Mobile broadband is a tougher matter, though.

Whither WiMAX?


It might seem odd to question just how big the WiMAX infrastructure market might be, given strong support from the likes of Intel and others who see a data device optimized broadband network as a huge opportunity. And maybe WiMAX ultimately will create a large enough global base of infrastructure that handset and device manufacturers will have a large opportunity.

But potential end user volumes matter, and matter a lot, in today's world. The issue isn't whether WiMAX will work. CDMA works. But global volumes for GSM networks are so large that device innovation is higher on the GSM than the CDMA sides of the ledger. Volume also is a factor for software developers, who prefer larger markets to smaller markets.

Sprint got people excited with plans to build a $5-billion, nation-wide network in the U.S. but that strategy is now in question. Sure, there's the rest of the world, but if you have followed mobile technology trends for any time, you are more careful about the installed base, and the potential installed base.

In the third-quarter, Infonetics Research says, worldwide WiMax equipment sales climbed a mere six percent to $206-million. Meanwhile, worldwide unit shipments of fixed and mobile WiMAX equipment rose 16 percent in the third quarter of 2007.

Still, Infonetics is looking for Wi-Max to see annual growth of 87 percent between 2006 and 2010 as more carriers embrace the fourth-generation technology.

The number of worldwide WiMAX subscribers (fixed and mobile) is expected to skyrocket to close to 60 million in 2010, led by the Asian region, Infonetics says.

Still, there is the historic example of iDEN and CDMA to consider. Devices are more important than networks these days. And one has to contend with the issue of sheer mass, in that regard. There's no question that WiMAX will work. But that's not the crucial question. The issue is how large the market for WiMAX devices might be, compared to GSM and its derivatives.

Verizon to Dump CDMA for 4G


Verizon Wireless will base its fourth-generation mobile broadband network on LTE – Long Term Evolution – the technology developed within the Third Generation Partnership Project (3GPP) standards organization and based on GSM.

The selection of LTE means Verizon wants to align itself with the scale opportunities the global standard will provide, rather than extending its existing CDMA platform.

Verizon and Vodafone have a coordinated trial plan for LTE that begins in 2008. Trial suppliers include Alcatel-Lucent, Ericsson, Motorola, Nokia-Siemens, and Nortel. Discussions with device suppliers have expanded beyond traditional suppliers such as LG, Samsung, Motorola, Nokia, and Sony Ericsson, as consumer electronics companies anticipate embedded wireless functionality in their future products.

Users won't see 4G for several years, however, so there's no need to worry about existing CDMA equipment. The decision does call into question how much actual developer interest there will be in Verizon's new "open" CDMA platform, however.

No Contract, No Locking, Nobody


Sprint CEO Gary Forsee says Sprint is thinking about expanding the test area for an unlimited calling plan that doesn’t require customers to sign a contract. That's something Leap Wireless and MetroPCS already offer. Nokia meanwhile appears poised to start selling unlocked N95 series really-smart phones imminently. So far, no carriers seem willing to do both.

Of course, there are good financial reasons why carriers like contracts and locked phones. The former provides a more predictable revenue stream and the latter ensures lower churn. Apple doesn't like unlocking either, as it now participates in the recurring revenue stream.

At least some users would benefit from unlocking and contractless service. Anybody buying a Nokia N95, for example, is spending enough on a device that the portable computer (it seems too limiting to call it a phone) clearly is more important than any network.

Of course, the carriers increasingly will find themselves in the position of angering power users who can figure out other ways to use unlocked devices, with or without contracts. To the extent that an N95 really is a mobile media and Web platform, outfitted both with Bluetooth and Wi-Fi, users can simply avoid any carrier "calling plan" if they are willing to put up with a little hassle and use Wi-Fi for connectivity.

That won't be very desirable for anybody who really needs mobile calling, but lots of people choose to carry two devices in any case. So maybe one of the new choices is one device for mobile email and voice, and the second for rich media and rich Web browsing.

It isn't so clear to me that a heavy email user is going to opt for an N95 in any case. The N95 excels as a rich media device (audio and video performance is spectacular) but won't satisfy a BlackBerry addict. The BlackBerry, though, isn't so great as a phone and really doesn't measure up as a media player.

Carriers might not like it, but devices are becoming the drivers of purchase and use behavior for a growing segment of the user base. Sure, the presence or non-presence of 3G capabilities is an issue. Operating system is getting to be more important. And then there's the blasted CDMA or GSM choice to be made. Pricing plans still are important, to be sure. But device coolness arguably is enough to outweigh the other considerations.

N95 might be among the first devices that test the theory that a powerful enough rich media device can get traction using Wi-Fi connectivity as an alternative to "mobile network" connectivity. Broad traction still will require 3G GSM. But N95 is the first device I've experienced that gets one to thinking about using it in a way similar to a laptop, rather than a phone. A Wi-Fi-equipped iPod is sort of in the same category.
