The Great Carrier Realignment: Verizon, Google, T-Mobile, AT&T, Motorola, SK Telecom, Sprint Nextel, and Others

By Glenn Fleishman

I’m trying to wrap my head around the series of announcements and developments this last week that will change the face of cell service, and notably wireless broadband in the U.S.: In short succession, you have:

• The FCC agreeing to some of Google et al.’s requests for open access requirements in the upcoming 700 MHz auction
• Gary Forsee resigning, having been forced out as Sprint Nextel’s head over merger execution and customer retention problems
• Google and its dozens of partners (including T-Mobile and Sprint Nextel as carriers and Motorola as a handset maker and Qualcomm as a fundamental technology provider and chipmaker) announcing the open Android platform
• Verizon ostensibly opening up its network to a much cheaper and easier way to offer any device and any service, which would mean it is dropping its complaints over the 700 MHz auction terms
• Verizon committing to LTE (Long Term Evolution), a form of advanced GSM for their fourth-generation network instead of a CDMA-based Qualcomm offering (AT&T and T-Mobile will almost certainly use LTE)
• SK Telecom (majority owner of MVNO Helio, which buys service from Sprint Nextel, and deployer of WiMax in South Korea) making a quickly rebuffed $5b investment offer with a private equity partner to reinstall Nextel’s former CEO as Sprint Nextel’s next CEO
• Motorola’s chief Ed Zander resigning after never recapturing the resurgence in the company’s fortune kicked off by the Razor phone
• Google committing to making a bid in the 700 MHz auction (Dec. 3 is the deadline to declare an intent to bid); that plus Verizon’s change of heart means that AT&T, Google, and Verizon will likely all be bidding on the national C Block licenses
• Various moves that are making it easier to unlock phones and break contracts without paying the full cancellation fee

Yes, it’s Google, Google, Google all over. While Google’s Android platform might not take off, it’s pretty clear that the disruptive influence of Google combined with the WiMax direction chosen by Sprint Nextel are reforming the future of the industry. But WiMax might get left out of the dance.

You see, with Forsee out of Sprint and Zander out of Motorola, you have two major firms that were committed to WiMax looking for leaders who will come in and not continue doing precisely what lead to their predecessors being forced out. Which means WiMax will be on the chopping block. Motorola could write down its Clearwire investment and spin off its Expedience division bought from that company, while refocusing on 3G and 4G cell. Sprint could decide to deploy something entirely different in 2.5 GHz, even if that delayed network buildout, rather than investing billions in something that they’re now not clear they want to move on.

On the consumer side, things are brighter. It’s likely that by 2009, we will see substantial competition among devices—think about the diversity of digital cameras available in sizes, formats, and features—where we might pick a device first and then choose a carrier. Android could be part of that mix, but the FCC’s pressure combined with market changes seem to be leading to cell networks in which you won’t have the same kind of lock-in and commitment—it’ll be more like Europe is but with greater competition reducing the cost of devices.

This openness could, in turn, supplant some of Wi-Fi’s forward momentum as the de facto wireless technology to build into portable devices. Wi-Fi is a best effort technology, which means that it’s not reliable. It’s a contention medium and there’s no company offering ubiquitous coverage—aggregators offer national and international subscriptions, but that’s not the same thing. If the cost of making and certifying devices to use on a cellular network drops precipitously, and volume of chips sold would be one of those factors, it wouldn’t be weird to buy a really good camera that has a 3G or 4G cell chip installed that you could use on a pay-as-you-go basis or as an add-on to an existing cell account you might have.

None of the cell carriers is particularly eager to allow more competition as that reduces margin, increases customer churn, and makes their returns more dependent on their short-term actions as people migrate around. But the fact that so many carriers are now promoting actions that will make life harder on them and their shareholders means clearly that the momentum is there for this change to sink in.

Google could sit back and do nothing, and they’ve already forced change. Sprint can’t sit back and do nothing—but there’s speculation Google might simply purchase them to pursue its goals. I doubt it, but Sprint will be a very different company within a year.

NTT DoCoMo Closes on 5 Gbps in 4G Research

By Glenn Fleishman

NTT DoCoMo said they hit nearly 5 Gbps between a transmitter and receiver, with the receiver moving at 10 km/h: A year ago, they hit 2.5 Gbps. The new device doubles MIMO antennas from 6 to 12 and improves signal processing. The same 100 MHz of spectrum was used. The company will release details at next week’s 3GSM World Congress in Barcelona, Spain. 4G was thought to be slated to launch as early as 2010, but a Super 3G flavor of WCDMA will precede it with 100 Mbps speeds by 2010.

100 Mbps at 60 km/h from Samsung

By Glenn Fleishman

The Wall Street Journal reports on an expected demonstration by Samsung of a 4G network: Many kinds of networks are now labeled 4G (fourth generation), such as Sprint Nextel’s planned mobile WiMax network, because 4G originally meant “all Internet protocol.” No more of this circuit-switched emulation with proprietary this and that. (There will probably still be proprietary this and that in 4G, of course.)

Samsung will reportedly show a mobile data system that operates at 100 Mbps at speeds up to 60 km per hour (37 miles per hour) as well as a nomadic connection with 1 Gbps performance. The Journal notes that NTT DoCoMo showed 2.5 Gbps at 12.4 mph—in the lab—as part of a previous technology demo.

Service using this definition of 4G isn’t expected until 2010.

Update: Coverage from the Korea Times says that “yesterday’s” demo—the international dateline plays havoc with us all—showed not just a demonstration of 1 Gbps performance at rest, but Samsung disclosed they had hit 3.5 Gbps at 5 km/h (3 mph) in the lab, thus surpassing NTT DoCoMo’s reported top rate.

The demos took place in a bus that showed 32 simultaneous streaming high-definition video streams while video telephony and Internet browsing was also going on.
