The rationale behind AT&T's petition is basically that the deal requires more scrutiny. Their official statement on the matter, sent to us by an AT&T spokesman, is that, "While AT&T does not fundamentally oppose the underlying transaction, Sprint and Clearwire should be required to demonstrate that its merger serves the public interest just like any other providers would have to do." Specifically, a significant chunk of the 2.5GHz spectrum their network will run on is actually leased from the schools and non-profits (which use it for the Educational Broadband Service).

According to Ars, AT&T is arguing that if you count the spectrum holdings Sprint and Clearwire lease from the EBS license holders, they pass the threshold requiring a "competitive analysis" of what the spectrum landscape would look like post-merger, which they don't have in their merger filings. Even though, as Ars points out, when AT&T bought Dobson Communications last year, they said EBS spectrum didn't really count.

So, it has to be asked—is AT&T finally scared of WiMax? [Ars Technica]

GSM is the most widely used mobile standard—210 countries—and by AT&T and T-Mobile in the US. What's groovy about GSM is that any device that'll take a SIM card—"subscriber identity module" is a chip that identifies you to the network and allows you to get on—can get you on a local network. Hence the market for "unlocked" phones that aren't tied to any carrier, which you can just pop an AT&T or T-Mobile SIM card in. It's also AT&T's response to Verizon's open initiative: GSM networks are technically already open.

CDMA is a competing voice-and-data standard that is smaller in distribution—but highly prevalent in Korea, Japan, South America and the US, on the networks of Verizon Wireless and Sprint (including MVNOs such as Helio and Virgin Mobile). CDMA is actually more efficient in terms of the way it uses channels, but it doesn't have GSM's "open" advantage of SIM card swapping. (This is why you can't take your iPhone to Verizon.)

2G refers to any second-generation networks—like CDMA and GSM/GPRS—that are digital, and not analog (which would be 1G). It's mostly for voice, but there's some slow data, too. (Remember WAP?)

2.5G are data upgrades to 2G networks that allow for faster data transfer. EDGE is the best known, used by T-Mobile and AT&T (and the bane of iPhone owners everywhere) and a transitional tech to 3G. Still pretty pokey, topping out at 200kbps downstream real world. Verizon and Sprint have a 2.5G technology called 1XRTT.

3G Now we're talkin'. Third generation is what we finally call "mobile broadband," with the potential for early DSL-like speeds. In the US, this involves two standards: the CDMA-based EV-DO for Verizon and Sprint, and HSPA for AT&T (running now) and T-Mobile (coming this year). Japan, parts of Asia and Europe also make use of W-CDMA. Despite the name, it's actually a GSM technology developed by NTT DoCoMo. For Americans this doesn't matter and only confuses things, so forgetaboutit.

HSPA High-Speed Packet Access is the umbrella term for two complementary GSM technologies, HSDPA and HSUPA, with the D and U standing for "downlink" and "uplink" respectively. Currently HSDPA can pull down info at speeds up to 14.4Mbps, but in the US it's more like 3.6, and only under amazing conditions. AT&T plans to hit 7.2 later this year. HSUPA is an add-on to HSDPA, rolling out in the US this year, which can transmit data at up to 5.7 Mbps, up from 384Kbps.

EV-DO is CDMA's 3G data service, used by Sprint and Verizon. There are different revisions, called Revs. The latest, Rev. A, is capable of 3.1Mbps downstream and 1.8Mbps up in ideal conditions. Though its specs are not as hot as HSPA, it is the most robust and widespread 3G network currently in the US.

4G is the near future of wireless data, with download speeds equivalent to or faster than most US broadband networks.

WiMax is 4G ultra-high-speed mobile broadband developed by Intel, Motorola and Samsung. In the US, Sprint is the only carrier planning to deploy it nationwide. WiMax promises incredible long range and connectivity on par with what you can get at home—think of it as Wi-Fi on 'roids. It was supposed to roll out hard this year, but Sprint has been having a lot of internal problems, necessitating cash injections from partners like Intel. Consequently, you probably won't see WiMax till '09 or '10.

LTE Long-Term Evolution is the other major 4G ultra-high-speed mobile data dealio. It's a GSM-based technology, and quickly emerging as the dominant next-gen standard, in part thanks to WiMax's stupor and Verizon's adoption of it. Though Verizon and AT&T have competing formats currently (CDMA and GSM respectively), both pledge to roll out LTE in the US. Verizon will do this as an overlay to its current network, meaning both CDMA phones and new LTE devices will work throughout the footprint. You'll start seeing LTE in the US in 2010 with mass coverage by 2012.

We skipped over some acronyms, and sped past others, but this should be all you really need to know to navigate Giz's mobile device coverage, so do yourself a favor and bookmark it.

Do you want Giz Explains to clear up any areas of overwhelming confusion? If so, fire a message to our Tips line with the subject "Giz Explains," and we'll see what we can do.

• When the rollout is already slower than people initially hoped, the aforementioned delays are never good.

• Aside from the Nokia N810, Asus Eee PC and Everex Cloudbook, Xohm lacks any mainstream WiMax-compliant devices, and we were hoping CTIA 2008 would be a good time to hear about them. An infrastructure is only as good as its end-user products (and vice-versa).

• Speaking of that, where are Intel's WiMax-compatible chips? What about the 20% of 2008 devices scheduled to have WiMax? What about the Montevina chipsets allegedly eagerly awaited by Lenovo, Acer, Asus, Panasonic and Toshiba? WiMax needs some love from its $2 billion champion.

• Xohm partners we spoke to were under the impression that a full Xohm demo would be set up for CTIA. However, Wired's Joe Brown attended Nokia's press conference and noted the N810 WiMax Edition Tablet was demoed over Wi-Fi. What's up with that?

• Similarly, while previewing the N810's HAVA Player at Nokia's booth, the Hava rep told me he was using Wi-Fi for demos because the Xohm booth just across the hall didn't have a strong enough WiMax signal. Laptop Magazine even suffered dropped connections inside the Xohm booth. What ever happened to 10Mbps at 10 kilometers?

• The WiMax demos that did work seemed promising, but the people running the booth operated with a healthy amount of paranoia. We weren't allowed to get too hands-on and they tried to kill our photos, suggesting perhaps things weren't as fully functional as they seemed.

• An early WiMax service rolled out in Australia last month suffered an EPIC FAIL, quickly closed up shop and prompted the CEO to say "WiMax may not work." Could Xohm be suffering from similar problems?

• WiMax's direct 4G competition, LTE, chosen by America's two biggest and most powerful wireless carriers, already seems to be gaining steam, not to mention showing well in recent demos.

So guys, anything we can do to help? I want the future of technology to actually make it to the future. Lord knows I'd feel better knowing I could play World of Warcraft lag-free while sitting in the middle of the Mojave Desert, not that I own WoW or plan to visit the Mojave Desert, but you never know. Seriously, just give me my damn WiMax already!!

VERIZON WIRELESS SAYS SPECTRUM ADDITIONS FROM FCC'S AUCTION 73 WILL FURTHER COMPANY'S BROADBAND STRATEGY

BASKING RIDGE, N.J. - Verizon Wireless said today that the spectrum it gained in the FCC's recent 700 MHz auction is a critical piece of its overall broadband strategy to take advantage of the enormous opportunity for growth in data services in the future. The spectrum will allow the company to capture the full potential of its announced plan to deploy a Long Term Evolution (LTE) network and Open Development Initiative and the resulting next wave of wireless innovation. The company's comments were made in a conference call with the investment community this morning.

Verizon Wireless was the winning bidder for a nationwide spectrum footprint (excluding Alaska) in the FCC-termed C-Block group of licenses, plus 102 licenses for individual markets around the country.

In all, the company will pay $9.36 billion for these licenses, which equates to $1.03 per MHz Pop, compared with the auction average of $1.20.

The FCC announced the end of the auction on March 20, but the company was limited in commenting until the Commission's anti-collusion quiet period rules ended late in the day on April 3.

The new spectrum, which will not be completely cleared for use until mid-February 2009, will increase the company's average spectrum depth per market to 82 MHz, from 52 MHz today.

Verizon Wireless plans to launch its LTE network in the 700 MHz spectrum in the 2010 timeframe. The company said the breadth of the national C-block spectrum footprint, all in a single band and with a depth of 22 MHz, provides a speed and performance advantage that will be ideal for connecting a variety of consumer electronics, from wireless phones to medical devices to gaming consoles. In addition, the 102 individual licenses in the A and B-blocks provide additional growth capacity in key markets.

"The spectrum we purchased in this auction, combined with our existing portfolio, provides new flexibility as we execute our high-growth business model," said Lowell McAdam, the company's president and CEO.

"We now have sufficient spectrum to continue growing our business and data revenues well into - and possibly through - the next decade, and this is the very best spectrum with excellent propagation and in-building characteristics. We also believe that the combination of the national, contiguous, same-frequency C-block footprint and our transition to LTE will make Verizon the preferred partner for developers of a new wave of consumer electronics and applications using this next generation technology.

"In all, this spectrum positions us well to preserve our current advantage and reputation as the nation's most reliable wireless network and the leader in data services. This is a wise investment in future data growth opportunities," he said.

VERIZON SELECTS LTE AS 4G WIRELESS BROADBAND DIRECTION

Technology Platform to be Trialed in 2008

BASKING RIDGE, N.J. - Verizon today announced plans to develop and deploy its fourth generation mobile broadband network using LTE - Long Term Evolution - the technology developed within the Third Generation Partnership Project (3GPP) standards organization. The selection of LTE provides Verizon and Vodafone - joint owners of U.S.-based Verizon Wireless - with a unique opportunity to adopt a common access platform with true global scale and compatibility with existing technologies of both companies.

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. These suppliers, along with others in the world community, have contributed significantly towards development of the standards in 3GPP. 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.

Working within 3GPP, Verizon and Vodafone, as well as a broad group of infrastructure suppliers, device suppliers, and technology companies from around the globe, have advanced the standards to enable a technology that will deliver unprecedented wireless broadband service for high performance mobile computing, multimedia, and consumer electronic devices and applications. The technology is designed to deliver mobile data networks with higher speed and throughput performance, lower latency, global roaming, and improved efficiencies.

Today's LTE announcement builds on Verizon Wireless' technology leadership as the first company to launch high-speed wireless broadband service in the United States using CDMA Evolution-Data Optimized (EV-DO) technology. Its data innovation and leadership have been marked by the introduction of new multimedia handsets and innovative applications such as V CAST Music, V CAST Video, VZ NavigatorSM, V CAST games, e-mail, Internet access, and picture and video messaging on a variety of devices, including handsets, PDAs and laptops.

Richard Lynch, executive vice president and chief technology officer of Verizon Communications observed that "while this next generation technology will be exciting to develop and deploy, it comes at a time when we are adding record numbers of customers to our existing CDMA2000 1x and EV-DO networks. We relish the challenge of preparing for the time when our customers start demanding such 4G capabilities, while continuing the expansion and operation of our existing technologies for many years to come."

"The company's move toward a 4G network is driven by our vision of pervasive wireless Internet connectivity and mobility," said Lynch. "Customers want to be truly untethered with advanced communication devices that provide functionality comparable to today's wired networks - whether it's downloading or uploading video, gaming, downloading their favorite music, or social networking. They want to be able to communicate in new and innovative ways whenever and wherever they choose around the globe. A number of factors are setting the stage for our 4G network migration; most importantly, our view of customers' evolving appetite for more information, entertainment, and functionality, combined with an increasing customer expectation for easy access, high speed, easy handling, and seamless mobility. With a host of new devices and applications, and a particular focus on embedded wireless in virtually every piece of electronics you buy in any store, we believe LTE is the best technology with global scale to deliver on the promise."

"Vodafone is delighted to be working alongside Verizon in the development of LTE technology, and we're looking forward to assessing the results of the joint engineering trials. We fully support Verizon's decision to select LTE as their next generation wireless broadband solution," said Steve Pusey, Vodafone's global chief technology officer. "We expect LTE to form a key part of Vodafone's future technology strategy, and the prospect of moving towards a common platform with Verizon Wireless is an attractive long-term goal. LTE will build on the capabilities of Vodafone's 3G broadband High Speed Packet Access (HSPA) network technology, which is available across the entire Vodafone 3G footprint."

"Today's 4G announcement, coupled with our Open Development initiative announced earlier this week present a major growth opportunity for Verizon Wireless," said Doreen Toben, chief financial officer of Verizon. "Fourth generation's higher data speeds will usher in a new era of wireless applications and appliances, all of which can benefit from connecting to the nation's premier wireless network."

This will end a decade or more of competing network technologies in the US, and might open the door to roaming agreements between the two biggest carriers. Who knows, one day the US may have a wireless business that works more like Europe's, where hardware makers play a greater role. What am I saying? They'll probably still be locked up beyond belief, but at least the FCC will have an easier time. [Ars Technica]
