T-Mobile USA is late to the high-speed wireless party, but it's going low-cost to catch up.
While rivals such as
AT&T, Verizon Wireless, and Sprint Nextel have been talking recently about building new 4G wireless networks, T-Mobile--which will begin offering 3G wireless service this summer--is leveraging cheap, unlicensed Wi-Fi technology to bring true broadband speed over wireless networks to some of its subscribers today.
There's no question Wi-Fi is far from perfect. Its use of unlicensed bandwidth can mean signal interference. And it's a short-range radio technology that will never be able to provide ubiquitous coverage. But when Wi-Fi is combined with a new 3G wireless network using phones that T-Mobile claims switch seamlessly between the two networks, it becomes an interesting story.
As the smallest nationwide carrier in the U.S. market, T-Mobile is using $4.2 billion worth of spectrum it bought in the Federal Communications Commission's 2006 Advanced Wireless Auction to build a 3G wireless network that operates in the nation's top markets. The service, expected to launch this summer, will be up and running in 80 percent of the top 20 markets by the end of the year, according to Joe Sims, vice president and general manager of broadband products and services for T-Mobile USA.
Even without 3G services, T-Mobile has managed to become a formidable competitor. And even though it doesn't offer specific e-mail or Internet surfing service over its cellular network, T-Mobile has still managed to become a leader in messaging with its popular Sidekick device that's used for SMS text messaging.
Now, as T-Mobile prepares to open its 3G network for business, the carrier has also begun offering a companion service using Wi-Fi that will provide even faster upload and download speeds for mobile-phone users. And while Sprint Nextel struggles to roll out WiMax and Verizon Wireless and AT&T talk about LTE (long-term evolution) deployments, T-Mobile will be able to offer its subscribers true mobile broadband service through Wi-Fi hot spots. The combination of its 3G network and Wi-Fi strategy could help the company compete more aggressively as mobile Internet and data become more important sources of revenue for wireless operators.
"WiMax and LTE are a ways off from becoming reality," Sims said. "There isn't anything faster than Wi-Fi right now. And with the seamless handoff to a 3G network, we can get much wider coverage."
Last summer, T-Mobile launched the Hotspot @Home service, which allows people using any of T-Mobile's dual-mode Wi-Fi/cellular phones to use their home Wi-Fi networks instead of the T-Mobile cellular network to make phone calls or access the Internet from their phones.
The company has expanded the service to also include its more than 9,000 public Wi-Fi hot spots in the U.S., giving its customers even more places where they can use Wi-Fi. I must admit, I have never used the service myself, but T-Mobile's Sims says the handoff between the Wi-Fi and the cellular is seamless, and subscribers can walk in and out of either network as many times as they like without ever noticing they have hopped onto another network.
Since the Hotspot @Home service launched nationwide last summer, T-Mobile has assembled an impressive list of devices that can be used with the service. Earlier this month at the CTIA trade show in Las Vegas, the company introduced the BlackBerry Pearl 8120 with Wi-Fi. T-Mobile also offers two other Hotspot@Home-enabled BlackBerrys, the popular Curve 8320, and the business-centric BlackBerry 8820.
Using the Wi-Fi network instead of the cellular network benefits T-Mobile, as well as its customers. For T-Mobile, Wi-Fi helps reduce the amount of traffic that is running on T-Mobile's own wireless network. And consumers get better in-home or in-building coverage. It also greatly improves the upload and download speeds for surfing the mobile Web. And at only $9.99 extra per month for subscribers who spend at least $40 a month on T-Mobile phone service, it's not an expensive add-on for high-speed data access and better coverage.
The service, which began selling nationwide last year, has been a big success, Sims says. It's even helped the company entice some customers to switch providers for T-Mobile.
"Over half of the @Home customers are new subscribers to T-Mobile," he said. "And most of them seem to be coming on for the faster speeds and the increased coverage proposition."
T-Mobile also recently announced a home phone replacement service called Hotspot @Home Talk Forever that also uses Wi-Fi. The service is currently available in Seattle and Dallas. Essentially, it is a voice over IP service, much like services offered by cable providers and companies such as Vonage. It allows people to use their regular phones to make and receive calls over a broadband connection. The service only costs $9.99 more a month on top of the regular calling plan and Hotspot @Home charge.
"Hotspot @Home is great for one device and great for improving in-home coverage," Sims said. "But there's another demographic that wants one permanent line in the home."
He admitted that the new service is an attempt to take on companies such as AT&T and Verizon, which offer wireless as well as home phone service.
"We are absolutely going after the traditional phone companies with these offerings," he said. "And we're doing it in a way that is relevant to our brand."
But Sims also says that T-Mobile's ambitions for Wi-Fi go beyond simply using it in the home. The service can also be used in conjunction with thousands of T-Mobile public Wi-Fi hot spots. The company currently has more than 21,000 public hot spots around the globe, with more than 9,000 of them in the U.S. While these hot spots by no means provide ubiquitous coverage, Sims said the company is evaluating how to expand its hot spot footprint to bring more Wi-Fi access to its subscribers.
Currently, most of T-Mobile's hot spots are in places like airports or cafes where people typically use laptops. But as more dual-mode phones come online, he said the company will evaluate where it might be useful to deploy hot spots for "nomadic" use.
Considering citywide Wi-FiHe even admitted that the company has considered deploying Wi-Fi citywide. The movement to blanket cities with Wi-Fi was badly damaged last year when EarthLink, the largest Internet provider to offer such a service, decided to stop building these networks. Since then cities have been struggling to figure out ways to bring inexpensive Wi-Fi services to their communities.
T-Mobile could be the perfect candidate to build such a network. Not only does the company already have its own Wi-Fi networks, but the use of dual-mode devices that can switch between cellular and Wi-Fi networks would make the service more useful and appealing to nomadic city workers or even consumer subscribers looking for faster mobile Internet surfing.
"We've looked at citywide Wi-Fi," Sims said. "There's no real reason why it couldn't work from a technology standpoint. But there are different business models around using the technology in that way."
T-Mobile's service is already being used on some Wi-Fi-blanketed college campuses. The University of Texas at Austin launched a pilot program last month that will run through August and is allowing T-Mobile subscribers to use the university Wi-Fi network as part of their Hotspot @Home service. This means that in addition to using the @Home service in a dorm room, residents and faculty who subscribe to the T-Mobile service will be able to use it anywhere they can find the university Wi-Fi network, such as in the library, in classroom buildings, and in outdoor public hot spots.
The main reason the university is interested in allowing the T-Mobile service to be used with its Wi-Fi network is to provide better in-building coverage. The university currently is working with all the major cell phone carriers to improve cellular coverage on campus, but even with these efforts faculty and students complain of poor service inside many buildings.
Instead of investing in expensive femtocell technology, which uses a router-like device to boost cellular radio signals indoors, William Green, director of networking for the University of Texas at Austin, sees Wi-Fi as an inexpensive way to provide better coverage. At the same time, people in the university community with dual-mode phones can also benefit from the higher-speed network access using Wi-Fi.
That said, Green is skeptical that T-Mobile's Wi-Fi service could be as effective in a citywide deployment.
"Wi-Fi networks are very hard to manage in dense environments," he said. "And it's very hard for a city to deploy a network such as ours. We already own the fiber and all the rights of way."
Skepticism over Wi-Fi strategyIndeed, other experts are also skeptical that T-Mobile's Wi-Fi strategy will find much traction beyond some niche applications. Roger Entner, vice president of communications for IAG Research, said T-Mobile has had little choice but to use Wi-Fi since it is so late to the 3G cellular game.
"They are trying to turn a virtue out of necessity," he said. "They're forcing a technology to be used in a way that it was not designed to be used. Can they get to it to work? Yes, but it doesn't work very elegantly."
At this point in the game, only time will tell. Sprint Nextel was supposed to have launched its Xohm WiMax service this month. But it now says it will launch the service later this year. And even though Nokia has announced one device to be used on a WiMax network, it will take awhile before more WiMax-enabled devices become available.
Then there's the other 4G technology, LTE. Verizon Wireless and AT&T have each said they plan to use wireless spectrum newly won in the 700MHz auction to build these networks, but it will be years before either provider offers a service on these proposed networks.
In the meantime, T-Mobile will be expanding its Wi-Fi hot spots and cell phone manufacturers will be embedding inexpensive Wi-Fi chips into more devices. So at least for the near future, T-Mobile, the laggard in the wireless speed war, could be the only provider to offer true wireless broadband speeds to its subscribers.
Coverage may not be everywhere, but it might just be enough to entice some subscribers to give it a second look.

Sony Ericsson posted a 47% drop in first quarter profits on Apr. 23, reconfirming a slump in high end phone sales in Western Europe and North America and underscoring the challenges ahead for the company’s new CEO, Hideki “Dick” Komiyama. Financial analysts have been sounding the alarm about a drop in demand for high end phones ever since Texas Instruments, a leading supplier of semiconductors for mobile phones, set off shock waves on Mar. 10 by lowering its first-quarter growth estimates for sales of wireless chips and pinned the blame on weakening demand from a major customer for high-end chips used to power third generation (3G) phones.
