AT&T Phone Company is once again challenging the imminent merger of Sprint Nextel with Clearwire, whose aim is to merge both companies’ WiMax assets in order to create a nationwide broadband wireless network.

This merger would be huge for Wimax, estimating a deal worth 14. 5 billion dollars, and is promising to be a huge success. Just ask Comcast (NASDAQ:CMCSA), Time Warner (NYSE:TWX), Intel (NASDAQ:INTC), and Google (NASDAQ:GOOG), all companies who are currently backing this magnanimous merger.

This union would be a grave threat to AT&T’s future success and longevity as a company, and therefore they are claiming that Sprint and Clearwire are “failing to make the required showings necessary for the commission’s review.” They are hoping that this new claim against Wimax would prohibit the FCC from approving its launch.

AT&T clearly understands the importance of mass mergers, seeing as how the company exists today solely because of a mergence between their company and Bellsouth. This alliance has allowed AT&T to grow and reach profound heights in profit margins and overall global accessibility. The same could all too easily occur as a result of the coalition between Sprint and Clearwire, an outcome that obviously leaves AT&T worried.

And AT&T has more than one reason to be nervous about the Wimax wireless network. AT&T is currently working on their own 3G wireless technology, but it is still light years away from the technology currently being deployed by the Sprint and Clearwire union.

With advanced technologies and unparalleled support from large corporations such as Intel and Google, it is no surprise why AT&T is scared about its ineludible launch.

The Sprint-Clearwire deal gave Clearwire undeniable credibility in WiMAX development, and the company is moving forward with the technology in a big way. Beta tests are underway in Portland, with “more than 70 percent of [the] WiMAX sites for Portland…in construction or on air.” Completion is slated for the end of year, with commercial deployments in that city and 3 others in 2009.

But now they have more than just the hardware; as of July 2nd, Clearwire has leased 3 one-year licenses on the 39 GHz spectrum from IDT Spectrum, 2 of which are in the Oregon-Washington area. You may not have heard much about IDT Spectrum recently, but expect to hear the name much in the near future; they own spectrums nationwide, mostly in the 28 and 38/39 GHz range. As we come upon the dawning age of wireless, the value of spectrum cannot be understated: you need spectrum to do anything wireless–especially for WiMAX, which is contentionless. (That means it can only operate on licensed spectrum because it is built to assume the air is clear. If it isn’t, the equipment just doesn’t work! ). Naturally, some companies are trying to develop equipment to change that, but for now, that is the nature of most WiMAX equipment. Those who bought spectrum when a majority of it was auctioned off by the FCC in the 80s are finally seeing their investment bear fruit, whether they intend to lease or sell –  remember the 700MHz auction earlier this year, which grossed a total of $19 billion?

So Clearwire has hardware, spectrum, and is well underway in deployment; what’s to follow ? If all goes well, 2009 will see Las Vegas, Grand Rapids, Atlanta, and Portland commercial launches as the first four commercial markets for Clearwire’s WiMAX service, primed to follow at the heels of the Xohm launches in Baltimore, Chicago, and Washington D.C. in the fall of this year. The start of the WiMAX nationwide buildout is only months away.

WiMax news has been dominated by a London research firm’s recent announcement that mobile WiMax might be dead on arrival.

“Recent events have been unfavourable toward Mobile WiMAX,” says Frost & Sullivan’s Programme Manager Luke Thomas, referring to Sprint’s delayed deployment of its commercial WiMax network. The firm then focuses on the two aspects of mobile WiMax:

“In terms of indoor wireless broadband, Wi-Fi fits well in this space and with the emergence of 802.11n, which includes MIMO, throughputs would be far better than what MobileWiMAX can deliver…With respect to outdoor mobile broadband environments, users would expect Mobile WiMAX to seamlessly hand off to cellular networks in the absence of WiMAX reception. In reality this is not possible as mobile WiMAX is not backward compatible with existing cellular technologies.” (Centre Daily)

By their diagnosis, the future of mobile WiMax seems bleak indeed. However, the image they portray may be oversimplified to WiMax’s disfavor. For instance, most next-generation broadband technologies will radically change modes of operation, making them incompatible with prior hardware. And before you ask, yes, in this club is the much-championed LTE. So in any discussion of new mobile technology, upgrading existing equipment is almost a given. It’s certainly much more of an industry-wide hurdle than, as Frost & Sullivan make it seem, an obstacle of WiMax exclusively. And already the industry is moving towards a solution, with talks of multimode.

As for the talk of the 802.11n standard of WiFi: last I heard, parts of the standard were still under patent in Australia, and requests for Letters of Assurance were ignored. That’s not a good portent for the standard’s likelihood of approval, as fast as it may be. I’d much rather look to WiMax, which is set to launch in its first large U.S. metropolitan area, Baltimore, in September.

With the new year, investors and all breeds of business people are re-evaluating–and maybe even crossing their fingers–for the industries they’ve put their money on. Many are wondering if this will be the big year for WiMAX in particular. Fortune seems to think so. In an article entitled ”The Top 10 Wireless Trends for 2008” WiMAX came in at number five with some buzz about Xohm and Nokia’s WiMAX-enabled Internet tablet.

Also noteworthy is the fact that nearly all the other listed trends either go hand-in-hand with WiMAX or would benefit from the deployment of a nationwide network. For instance, camera phones with much more advanced functions are listed as one hot trend. With WiMAX, sending and receiving cell phone pictures would be so much faster and easier than it is on traditional cellular networks. Furthermore, WiMAX aficionados even speak of traditional digital cameras becoming WiMAX-enabled, with the ability to quickly and easily upload pictures to blogs, e-mails or other devices without ever touching a USB cord or PC. If camera phones have hit big, how much more so would a WiMAX-enabled camera be likely to hit the trend list?

For 2008, investors and others with a hand in WiMAX will be happy to see that secular sources are keeping an eye on WiMAX. The public’s technological needs and desires can be matched by what WiMAX has to offer–the key is getting it out there for the taking.
