What is 4G?
By Dan O'Shea

U.S. mobile carrier giant Sprint announced this week that it has chosen Mobile WiMAX as the technology for its 4G network evolution, thereby helping make Mobile WiMAX synonymous with 4G.

But what exactly is 4G? Is it personal broadband, the WiMAX Forum's personal cause celebre? To many in the mobile industry, the 3GPP's Long Term Evolution standard still represents 4G. So if Mobile WiMAX is 4G for Sprint, then will LTE be 5G for Sprint and everyone else?

I don't pretend to know the answers to these questions, and perhaps the answers don't matter, as different carriers around the world may adopt different technologies at radically different paces, and may even skip solutions that represented significant generational upgrades for others.

And if the IP multimedia subsystem movement accomplishes what it set out to do, none of this may matter. Mobile or WiMAX access architectures will become increasingly transparent, and thus the adoption of multiple architectures by a single network operator increasingly common. But, what if you use Advances to IMS (Verizon Wireless' recent enhancement proposal) instead of IMS?

Technologies come in numerous flavors and have different labels attached to them, but that doesn't mean they are moving in different directions. A-IMS and IMS share the same core technology philosophy, and all the technologies that Sprint considered for 4G have something in common, too--orthogonal frequency division multiplexing.

Forget about WiMAX or LTE or any of those generational labels. We're all moving in the same direction, more or less...

What WiMAX was waiting for
Aug. 9, 2006

The WiMAX sector got what it was waiting for, the decision by Sprint to deploy Mobile WiMAX over other technology contenders. But, it also got what it really wanted most--a big U.S. mobile carrier stepping up to a microphone and telling a worldwide audience why Mobile WiMAX was the right choice for its nationwide 4G network evolution and why the other technologies or vendors weren't the right choice. Who in the WiMAX Forum sold their soul to make this happen? (Don't all answer at once...)

Seriously, WiMAX companies could not ask for a more public endorsement, or a more public dismissal of every other solution that has posed a threat to their livelihood--including 3G. In one fell swoop, Sprint has made Mobile WiMAX not just a wireline broadband alternative, not just an international alternative and not just a hype-up alternative for companies that don't have 3G--it has made Mobile WiMAX synonymous with 4G.

Having said that, let's now return to Earth for this brief disclaimer: Sprint's choice of Mobile WiMAX in no way confirms that Mobile WiMAX will be the 4G choice of other mobile carriers, or the most viable broadband choice for carriers in general. It doesn't mean that IPWireless or Qualcomm or any other vendor with a different technology hasn't already succeeded and won't further succeed with its own solutions. It doesn't even mean that Sprint, by the way, will continue to be an independent firm in the foreseeable future--its recent financial disappointments and precarious U.S. market position amid rebuilding Bell companies is leading to all kinds of speculation in that regard.

Mobile WiMAX still has a long road to travel, but the WiMAX community may have just gained enough credit to pay for the rest of that trip.

いや、ありえないでしょう。

SIMカードを使って別の端末を使うのでは意味がない。
昨年、友人が出張の時にDoCoMoの端末を借りて海外に飛び立ったが、なれない端末なので、日本語入力方法になれるまでに時間がかかったと嘆いていた。それに自分の端末であれば、ある程度の必要情報はメモなりで保有できるが、それなしでwebメールSNSへケータイからアクセス・・・ありえない!!

やっぱりもう少し考えよう・・・
