4G Americas, a wireless industry trade association representing the 3GPP family of technologies, today applauded the final ratification of LTE-Advanced as an offical 4G standard by the International Telecommunication Union (ITU).
Both LTE Advanced and WirelessMAN-Advanced (802.16m) are the real deal — ITU sanctioned 4G standards. Both will deliver up to 100 Mbps (mobile) and up to 1 Gbps (fixed). In order to deliver those speeds, however, both need 20 Mhz wide channels and up to 4×4 MIMO antennas on both the receiver and basestation.
In its October meeting, ITU’s Radiocommunication Sector (ITU-R) completed the assessment of six candidate submissions and reached a milestone by deciding on LTE-Advanced and WirelessMAN-Advanced for the first release of IMT-Advanced, their package of offical 4G standards.
Final ratification of the full IMT-Advanced technology family took place at the ITU-R Study Group meeting on November 22 and 23, 2010 in Geneva, Switzerland.
The standards will now move into the final stage of the IMT-Advanced process, which provides for the development in early 2012 of an ITU-R Recommendation specifying the in-depth technical standards for these radio technologies.
“This day is a milestone to remember for mobile broadband connectivity,” said Chris Pearson, President of 4G Americas. The future for mobile broadband technologies has never been brighter to help progress societies in the Americas and throughout the world.”

Alcatel Lucent forecasts more opportunity after deals in U.S. and China
BERLIN — Alcatel Lucent, which has struggled in the wake of its 2006 merger, said last Thursday that it had reached a “turning point” after clinching $5.7 billion in deals to build high-speed wireless networks and supply other gear for the biggest mobile operators in the United States and China.
The company, based in Paris, announced the contracts at the same time it reported its first profitable quarter of the year, posting €25 million, or $35.3 million, in earnings compared to a €182 million loss in the third quarter a year earlier. Sales rose 10.5 percent to €4.1 billion. The results missed forecasts of analysts surveyed by Reuters and Bloomberg News and shares were down more than 3 percent in Paris at midday, however.
Ben Verwaayen, the Alcatel Lucent chief executive, described the agreements with Verizon Wireless, the largest U.S. mobile operator, and the three biggest mobile carriers in China as “massive” for the company, which had struggled to reorganize and streamline in a weak global market following the merger of the French company Alcatel with Lucent Technologies, which was formerly part of AT&T, the U.S. phone giant.
Although the quarterly profit was attributed primarily to tax benefits associated with ongoing adjustments from the merger, Mr. Verwaayen said he did not think it would be “a one-time event.” Mr. Verwaayen mentioned that he think this is a significant turning point in the transformation of the company. They are experiencing good demand for their products.
Without one-time items, the company reported an operating loss of €11 million for the quarter, compared with a €76 million loss a year earlier. But Jouni Forsman, an analyst at Gartner in Nice, France, said that Alcatel Lucent had repositioned itself to become more competitive in the fastest-growing segments of the wireless equipment industry, where demand for network software upgrades, services and applications is strong among mobile operators.
According to Mr. Forsman, the company is executing on the turnaround story. They are in a much better position than they were a couple of years ago. They are controlling costs and executing in a difficult market.
The agreement with Verizon Wireless will generate $4 billion in sales over four years, Alcatel Lucent said. Under the pact, Alcatel Lucent will upgrade the operator’s third-generation wireless network and build a faster network based on a technology called Long Term Evolution. LTE networks, which can download wireless data at speeds much more rapidly than existing systems, are helping operators meet the surge in data traffic from streaming video and social networking services.
Alcatel Lucent said it planned on Friday to sign agreements worth a total €1.18 billion with China Mobile, China Telecom and China Unicom during a visit to France by the Chinese president, Hu Jintao.
Mr. Verwaayen, the Alcatel Lucent chief executive, said “a large chunk” of the sales to the Chinese carriers was new business, with the rest being a reaffirmation of existing sales arrangements. The Verizon sales, Mr. Verwaayen said, was all new business for his company.
Verizon Wireless, a joint venture of Verizon and Vodafone, the British global mobile operator, is upgrading its 3G networks to LTE through 2013 as it sells more data-intensive smartphones and other devices. Some analysts expect Verizon later this year to announce that it will become the second U.S. operator to sell the iPhone, which has only been sold by AT&T.

Purdue University Deploying 4G Network as Part of Wireless Rollout
Purdue University will be one of the early recipients of Verizon Wireless' rollout of a 4G network starting this year. This fourth generation data network, which is using Long-Term Evolution (LTE) technology, is expected to provide four to 10 times the transmission speeds currently available in 3G networks.
The institution was chosen to participate in the deployment based on its track record with using mobile technology to enhance learning, according to Lowell McAdam, president and chief operating officer of Verizon. Recent technologies developed at Purdue include Mixable, an academic integration with Facebook; a student discussion tool, HotSeat, which allows students to interact with classmates and faculty with Twitter and text messages; and eStadium, to deliver athletic game services to spectators.
The university also contracted with Verizon Business to implement a campuswide 802.11n wireless network, which will encompass 6,000 access points in 256 buildings. That project is expected to be completed in the 2010-2011 academic year.
Verizon said the broader rollout of 4G will include 38 metropolitan areas and 60 commercial airports, including Indianapolis International Airport, located within 90 minutes of the West Lafayette-based university. The company is currently installing LTE equipment at existing cell sites and switching centers around the United States.
According to Mr. McAdam, the partnership with Purdue will explore the next phase of how 4G technology can improve education across our nation. Verizon Wireless said it expects 4G LTE average data rates to be 5 Mbps to 12 Mbps on the downlink and 2 Mbps to 5 Mbps on the uplink in real-world, loaded network environments.
"At Purdue, the advancement of mobile technology is critically important--both to students and faculty. The addition of Verizon's 4G network will contribute in a noticeable way to their success," said Gerry McCartney, Purdue's CIO and vice president for IT.

LTE-Advanced & IEEE 802.16m WiMAX both officially selected as 4G standard by ITU
The Korea Communications Commission said Wednesday that two key mobile communication technologies -- Long Term Evolution-Advanced and WiBro Evolution -- were recently chosen as fourth generation (4G) global standards.
In a meeting in Vietnam held June 9-16, the International Telecommunication Union passed the global standardization tests for the two technologies, which are intended to be used as 4G mobile communication systems.
ITU is an international organization which specializes in deciding standards on radio and telecommunications.
The organization will complete developing the specific standardization framework for the new technologies by March 2011 and grant final approval in February 2012, according to KCC officials.
“With Korea playing a key role in the international standardization effort, the nation will be able to lead the way in designing core technologies for the next generation,” said Kim Jeong-sam, director of the radio spectrum policy division at the KCC.
The two new technologies, which are already adopted by many European and Asian countries, will enable mobile phone users to get faster access to the mobile Internet at comparable speeds to Web surfing on a personal computer.
Better known as WiMAX Evolution in other countries, the WiBro Evolution’s research has been led by Samsung Electronics and the state-funded Electronics and Telecommunications Research Institute.
WiBro Evolution is deemed to be 10 times faster the high-speed downlink packet access technology adopted by the current 3G mobile phones.
The initiative for technology standardization was taken forward by the Telecommunications Technology Association in Korea, which worked in cooperation with groups based in other nations such as Japan and the U.S.

Is WiMAX or LTE the better 4G choice in Malaysia?
WiMAX or LTE (long-term evolution) – which is superior? It, of course, depends on who you talk to. The vendors have their own stories, and the operators theirs. For the consumers, it is not about technology. It is about speed and seamless connectivity, and not having to buy different devices to operate on different platforms.
From the technical viewpoint, both are next-generation technologies for the wireless world. The choice between WiMAX and LTE hinges on the needs of the operator and the market demands, but the fact is, there seemingly is an insatiable appetite for data on the go.
WiMAX (worldwide interoperability for microwave access) is a fourth-generation (4G) telecommunications technology primarily for fast broadband.
Also a 4G mobile technology, LTE allows a peak download speed of 100 megabits per second (Mbps) on mobile phones, compared with 20Mbps for 3G and 40Mbps for WiMAX.
“For operators, the choice of technology depends on a number of things including available spectrum, legacy inter-working, timing and business focus,” says Nokia Siemens Networks head of sub region, Asia South, Lars Biese.
To deploy either technology, operators will have to commit tens of billions of dollars in network upgrades for the new mobility landscape, which now includes social, video, location-based and entertainment applications and experiences.
In many countries, the current generation of mobile telecoms networks is 3G. Those in Malaysia are deployed by the four mobile players – Celcom Axiata Bhd, DiGi.Com Bhd, Maxis Communications Bhd and U Mobile Sdn Bhd.
Biese reckons LTE is the next step for mobile networks like GSM, WCDMA/HSPA and CDMA in the move to future networks and services.
The common belief is that the natural migration path is from 2G to GPRS, from GPRS to 3G, and from 3G to LTE. But IDC Asia/Pacific’s telecom research director Bill Rojas has a differing view. To him, LTE is a totally new set-up.
“GSM and GPRS were part of a migration. In Asia, the players may put LTE on top of 3G, but this will not cover the entire population. The concentration will be on urban centres. For full coverage, the operator needs to build more than 30% new cell sites,” Rojas says.
It has been reported that LTE’s main advantage over WiMAX, in addition to speed, is that it is part of the popular GSM technology and can allow backward compatibility with both 2G and 3G networks.
LTE is relatively new compared with WiMAX. The world’s first public LTE service was made available only at the end of last year by TeliaSonera in Stockholm and Oslo.
Some people may said that LTE means "Late To Evolve"... However, LTE is fast catching up with WiMAX even though the WiMAX Forum, an industry organisation, stresses that its platform is at least two years ahead in terms of equipment availability and testing.
The Global Suppliers Association (GSA) says there are more than 59 LTE network commitments in 28 countries. In comparison, according to the WiMAX Forum, there are 559 WiMAX networks worldwide.
“To date, all existing GSM and WCDMA (3GPP) operators and CDMA (3GPP2) operators have committed to LTE as the technology of choice for their mobile network evolution, and by 2013, it is expected that there will be 20.4 million connections activated on LTE in the Asia Pacific,” says Biese.
On the other hand, YTL Communications Sdn Bhd chief executive officer Wing K Lee claims that mobile WiMAX is the only commercially proven technology that has been deployed on a large scale.
Nevertheless, market dynamics will determine the outcome of the race.
There are four WiMAX spectrum holders in Malaysia, namely, Packet One Networks (M) Sdn Bhd, REDtone International Bhd, Asiaspace Sdn Bhd and YTL Communications, which is the only one that has yet to roll out services commercially.
Rojas of IDC says both technologies can co-exist, but to him, WiMAX is still the purest 4G network. Naturally, the promoters of LTE have the opposite view.
That aside, Lee of YTL Communications points out that LTE and WiMAX serve the wireless broadband market and both technologies fundamentally share the same technological foundation. Therefore, they have more similarities than differences.
Should they then be merged, as suggested by US-based Clearwire CEO Bill Morrow, given the overlap in the technologies?
While the debate rages on, the mobile operators in Malaysia still have a little bit of time to decide on which route to take to add capacity. This is because they have not fully exhausted their 3G spectrum. Even the WiMAX players have not fully exploited their 2.3G spectrum.
At some point, Rojas believes, the Malaysian Government will have to decide on spectrum allocation for LTE. Until then, do not expect the operators to fast-track their network expansion, even though some may face bottlenecks soon.
Furthermore, the Government needs to be certain that LTE is what the market needs. “Without (additional) spectrum after 3G, operators will have to move to LTE using the 3G spectrum,’’ Rojas says.
Whatever is on the minds of the players and industry regulators, one thing is clear – the need for speed is growing by the day, and the planning for spectrum allocation should start before we hit bottlenecks.
Some industry players have also called for the Government to refarm spectrum so that there is a coordinated approach to spectrum allocation and assignment. Not that there isn’t, but given that spectrum is becoming a rare commodity, the Government should make sure that the spectrum awarded is put to good use.
Rojas expects major commercial roll-outs of LTE and WiMAX in Asia this year and next, but devices remain an issue in the world of 4G. At the same time, experts say it is about time that the industry focuses on a single device that works on all platforms.

WiMax vs. LTE: Which Will 'Win' in a Fast Deployment Cycle?
One of the biggest stories during the next year or so will be the rollout and subsequent marketing of 4G wireless networks.
It will be an interesting process as the two approaches – Long Term Evolution (LTE) and WiMax – vie for supremacy. The die already seems to be cast, however: WiMax, through Clearwire and its Clear service, is first out of the gate. LTE, however, through its use by Verizon and AT&T, seems positioned to be the dominant player when the dust settles.
WiMax suffered a bit of a blow earlier this month when Cisco decided not to build radios for the platform:
Technology is not an either/or game.The Cisco move clearly is not good news for WiMax, both in terms of image and because the vendor brings a lot to any table at which it chooses to sit. It’s also clear that WiMax will not be as big as LTE. All that said, however, it is apparent that WiMax remains a significant wireless networking force.
…WiMax is making strides with at least one significant niche category: smart grid networking. Earth2Tech reports that startup Arcadian Networks has released the AE20r gateway, a WiMax-focused device. The story says that Arcadian, which owns spectrum in the middle of the country, sells smart grid services to utilities. The story notes other vendors in the smart grid/WiMax arena, including Grid Net, General Electric, Alvarion and National Grid.
To be sure, Clearwire is not backing down:
Clearwire seems to be at the center of cable’s move to mobilize voice and advanced mobilized applications. FierceWireless, in a general report about Clearwire’s progress, said that the company plans to introduce a WiMax-enabled smartphone during 2010. The aim, according to CEO Bill Morrow, is to have the device in the field during the second half of the year. The story says that Sprint is planning 3G/4G phones, also by the end of 2010.
On the other side of town -- or of the R&D lab hallway -- is LTE. While WiMax was first out of the gate, the LTE sector is making up for lost time:
The LTE trial and test phase is white hot.
Driven by the increase in demand caused by fixed-rate data plans, coupled with the popularity of the iPhone and other advanced devices, the pace of testing of one of the two flavors of 4G technology, Long Term Evolution (LTE), is accelerating.
LTE is particularly active on the international front. ABI Research says that as of the end of September, 100 mobile networks were holding trials or were set to start. More than 40 of the trials are ongoing in the Asia-Pacific region – led by Japan and South Korea, with 33 contracts awarded. ABI Research says that though the first networks won’t start commercial operation until the end of next year, a robust 32.6 million subscribers will be served by LTE by 2013. The pressure is so great that many operators are taking the interim step of upgrading 3G networks to High Speed Packet Access (HSPA) status.
The stage was set once AT&T and, especially, Verizon made their choices:
Details are emerging on Verizon Wireless’s LTE rollout. Softpedia reports that the carrier, in one configuration, will offer per-user data speeds of 5 to 12 megabits per second (Mbps). The system will support video sharing, surveillance, conferencing and streaming. The story runs through the other advantages that Verizon Wireless is touting, and some of the challenges to older technologies that it supposedly alleviates.
The interesting thing is that LTE and WiMax are fairly close from the technical point of view. That means that it is theoretically possible for differences to be overcome and competition to become a thing of the past. While possible, it is thought unlikely:
On one hand, the battle for the future of 4G between LTE and WiMax will be fully joined. However, both are IP-based and use Orthogonal Frequency Division Multiplexing (OFDM) and, experts say, are relatively close on the telecommunications family tree. Indeed, the biggest difference may concern the other IP: intellectual property. Despite the maneuvering today, it is possible that in a few years the two will blend together.
The next year or so will be a good deal of fun for folks who like mano-a-mano competition, price pressure, glitzy ads -- and high-speed wireless networks. At the end of the day, it almost certainly is destined to end up as expected:
LTE will be the top dog, with WiMax a strong supporting player.

The Momentum Toward LTE Accelerates
The LTE trial and test phase is white hot.
Driven by the increase in demand cause by fixed-rate data plans coupled with the popularity of the iPhone and other advanced devices, the pace of testing of one of the two flavors of 4G technology, Long Term Evolution (LTE), is accelerating.
LTE is particularly active on the international front. ABI Research says that as of the end of September, 100 mobile networks were holding trials or were set to start. More than 40 of the trials are ongoing in the Asia-Pacific region – led by Japan and South Korea, with 33 contracts awarded. ABI Research says that though the first networks won’t start commercial operation until the end of next year, a robust 32.6 million subscribers will be served by LTE by 2013. The pressure is so great that many operators are taking the interim step of upgrading 3G networks to High Speed Packet Access (HSPA) status.
A snapshot of the ongoing trials shows how active the landscape is. For instance, Telecom Italia is conducting trials in conjunction with Huawei in Turin, Italy. Singtel is planning trials in Australia, Indonesia, the Philippines and Singapore. China Mobile said that it established a trial at the Shanghai World Expo Park and will launch what it says is the first Time Division Duplex (TD-LTE) trial next year, while Motorola claimed that it is the first vendor to complete and pass TD-LTE testing with China's Ministry of Industry and Information Technology.
That’s not all. This VON story says Nokia Siemens Networks and Telefonica are set for a six-month trial in the Czech Republic, and Huawei has been selected to integrate three different types of networks – GSM, HSPA and LTE, when it arrives – for Belgaom. Siemens Networks and LG Electronics have finished what Telecoms Korea says is the first end-to-end interoperability test in the 2100 MHz frequency band. The test used Nokia Siemens LTE equipment and LG’s LTE USB data card.
There certainly are more tests and trials ongoing or soon to launch. The significant head start of WiMax, the other 4G platform, clearly hasn’t stopped an almost frenetic level of activity from the LTE camp. This, of course, is good news for vendors, service providers and customers across the board.

The Future of 4G: LTE vs. WiMAX
LTE, the 4G mobile broadband technology backed by major cellular network equipment providers and operators, casts a long shadow across the WiMAX landscape—even though LTE products are thin on the ground and no operator has launched commercial service using it.
Verizon, however, has committed to rolling out LTE (Long Term Evolution)... (in joking mode they called it as "LTE: Late to Evolve") starting next year, delivering ten times the data throughput of current 3G technologies. Others, including NTT DoCoMo in Japan, France Telecom, Vodafone in the UK, AT&T, and T-Mobile, have also said they will adopt LTE rather than WiMAX.
Meanwhile, Sprint, Clearwire, and Comcast in the U.S., UQ Communications in Japan, and Yota in Russia are all aggressively rolling out mobile-capable “4G” networks using the current version of WiMAX, 802.16e (2 to 10 Mbps), in urban markets where they will inevitably compete with 3G (and later, LTE) providers.
The WiMAX Forum claims that 504 operators in 145 countries have deployed WiMAX, but many use older 802.16d technology that cannot provide mobile services, and many are small operators in developing countries or rural regions.
How will the market unfold? Are LTE and WiMAX on a collision course? If so, which will prevail. Or will the two technologies co-exist, even complement each other? The answers are far from clear, and depend to a large extent on who you ask.
Sprint and Clearwire’s use of the term 4G to describe their 802.16e technology does not reflect adherence to international standards, Redman pointed out. It refers to the fact that this is the fourth generation of mobile wireless technology deployed in North America.
How and when either camp will deliver a standard that does meet the yet-to-be-finalized ITU specs remains to be seen. It is anticipated that LTE will get there with revision 10 and WiMAX with a projected 802.16m. Estimates of when equipment based on these advanced standards will appear ranges from 2011 to 2015.
Despite the similarities of the two technologies, and despite suggestions from some that the two camps are notnecessarily on a collision course, discourse between and around them can get heated.
“Politics rules everything,” he said, explaining the reasons so many major mobile operators chose LTE rather than WiMAX as their upgrade path to 4G.
Those operators—Verizon, AT&T, NTT, et al—didn’t really choose the technology, Redman believes. They chose their suppliers: Ericsson and Nokia, tried-and-true Tier 1 mobile infrastructure equipment manufacturers that had decided not to back WiMAX.
If operators wanted to go with WiMAX, they had to bet on smaller Tier 2 suppliers, such as Motorola, Alcatel-Lucent, and Alvarion. “It’s all about who you feel most comfortable with,” Redman said. Better the devil you know?
The Tier 1 suppliers, in turn, backed LTE over WiMAX because they saw that, for a variety of reasons, they could make more profit selling LTE. “In many cases, it was more a political decision than one based on technology or cost,” he said.
Redman has reportedly gone as far as urging businesses to hold off on investing in WiMAX, at least until the equipment ecosystem evolves to make dual-mode 3G-WiMAX devices more readily available.
This enraged some elements in the WiMAX camp. One Intel blogger characterized Gartner’s analysis of the market as “the most recent attempt at ‘drive-by kneecapping’” of the technology.
When we repeated to Proulx Redman’s suggestion that WiMAX vs. LTE might be analogous in some ways to the showdown between VHS and Betamax video cassette formats in the 1970s—with WiMAX taking the doomed Betamax role—her response was blunt.
“It’s a silly analogy and it’s unfortunate it’s been repeated so often,” she said. Proulx noted that Betamax was a proprietary technology, backed by one supplier (Sony) and was more expensive than its competitor—none of which is remotely true of WiMAX.
Proulx was similarly direct in responding to Redman’s suggestion that 802.16m is a more uncertain proposition than LTE Rev 10 and may not even be backward compatible to 802.16e. “From day one,” she said, “the first [design] requirement [for 802.16m] was that it be fully backward compatible. I think you’ll see evidence of that very soon.”
Chua apparently does not raise the ire of the WiMAX community to the same extent as Redman, but his perspective is not so different.
IDC believes operators rarely have made or will make either/or choices between LTE and WiMAX. More often, decisions will be made for them because only one technology or the other can meet all their needs—given time-to-market, desired business model, and other considerations.
“We characterize WiMAX and LTE as two circles that overlap,” Chua said. “Inevitably there will be some competition, but competition is not the overriding market scenario. It’s not what defines those two markets.”
IDC will publish a forecast later this year showing sales of LTE equipment surpassing WiMAX equipment sales some time in 2012.
But it may not be as simple as 3G mobile users in developed markets sticking with their current providers and waiting for LTE (because of LTE is "Late To Evolve"), while WiMAX is relegated to a niche role delivering portable rather than mobile service in developing countries and rural regions.
For one thing, the WiMAX camp believes the momentum it’s currently building in those developing markets will drive development of an ecosystem, help harden the technology—and put it in good position to be a full competitor in the 4G mobile market down the road.
Indeed, the fact that WiMAX lets operators in those markets start small and build businesses organically without investing billions of dollars is one of its key advantages over LTE, Proulx said. Operators may start by providing DSL replacement services, but can easily evolve to offering true mobile services when they have the breadth of coverage and market demand.
And then there are the implications of exceptional initiatives in more developed markets—Clearwire in the U.S., Yota in Russian, UQ in Japan. Yota is currently signing up 2,000 new subscribers a month in St. Petersburg and Moscow and already has 200,000 since launching last fall, Proulx said.
While Clearwire has been slow to introduce WiMAX-powered phones or dual-mode 3G-WiMAX phones that would help it attract customers away from 3G providers, Yota is already building much of its marketing around a dual-mode device from HTC.
Most observers agree that the winners in the 4G market will be those that offer the widest coverage, the most reliable service and the best choice of devices. Redman is skeptical Clearwire can build its network out quickly enough to give it the breadth of coverage needed to attract 3G customers. The company will need another big infusion of capital next year just to continue its current pace, he added.
But Proulx believes WiMAX can compete with 3G operators, if not immediately in the U.S. then soon—and perhaps sooner in Japan. There, she said, UQ expects to have 90% of the Japanese population covered by its network by the end of 2010. If true, that would be before NTT is even out of the gate with LTE.
Redman and Chua may be underestimating the market strength of WiMAX—or not. Either way, no one is seriously suggesting it will be blown out of the water by LTE. The two will co-exist, whether or not peacefully remains to be seen.
Indeed, the picture is unclear and may be no clearer until 2011 when commercial services using both will be available in the U.S. and elsewhere. Stay tuned.
Verizon, however, has committed to rolling out LTE (Long Term Evolution)... (in joking mode they called it as "LTE: Late to Evolve") starting next year, delivering ten times the data throughput of current 3G technologies. Others, including NTT DoCoMo in Japan, France Telecom, Vodafone in the UK, AT&T, and T-Mobile, have also said they will adopt LTE rather than WiMAX.
Meanwhile, Sprint, Clearwire, and Comcast in the U.S., UQ Communications in Japan, and Yota in Russia are all aggressively rolling out mobile-capable “4G” networks using the current version of WiMAX, 802.16e (2 to 10 Mbps), in urban markets where they will inevitably compete with 3G (and later, LTE) providers.
The WiMAX Forum claims that 504 operators in 145 countries have deployed WiMAX, but many use older 802.16d technology that cannot provide mobile services, and many are small operators in developing countries or rural regions.
How will the market unfold? Are LTE and WiMAX on a collision course? If so, which will prevail. Or will the two technologies co-exist, even complement each other? The answers are far from clear, and depend to a large extent on who you ask.
Defining “4G”
The ITU, the International Telecommunications Union, is developing specifications for 4G mobile. Neither WiMAX, 802.16e, nor the current LTE standard, revision 8, meet basic preliminary objectives for 4G, said Phillip Redman, a vice president of research at consulting and analyst firm Gartner Inc.Sprint and Clearwire’s use of the term 4G to describe their 802.16e technology does not reflect adherence to international standards, Redman pointed out. It refers to the fact that this is the fourth generation of mobile wireless technology deployed in North America.
How and when either camp will deliver a standard that does meet the yet-to-be-finalized ITU specs remains to be seen. It is anticipated that LTE will get there with revision 10 and WiMAX with a projected 802.16m. Estimates of when equipment based on these advanced standards will appear ranges from 2011 to 2015.
Despite the similarities of the two technologies, and despite suggestions from some that the two camps are notnecessarily on a collision course, discourse between and around them can get heated.
In this corner
Redman wrote in a report last year, "WiMAX drives the hype for 4G, but LTE will be the dominant standard," A WiMAX skeptic and a perceived thorn in the industry’s side, he believes LTE’s dominance is not a question of technological superiority or even cost, but of market politics.“Politics rules everything,” he said, explaining the reasons so many major mobile operators chose LTE rather than WiMAX as their upgrade path to 4G.
Those operators—Verizon, AT&T, NTT, et al—didn’t really choose the technology, Redman believes. They chose their suppliers: Ericsson and Nokia, tried-and-true Tier 1 mobile infrastructure equipment manufacturers that had decided not to back WiMAX.
If operators wanted to go with WiMAX, they had to bet on smaller Tier 2 suppliers, such as Motorola, Alcatel-Lucent, and Alvarion. “It’s all about who you feel most comfortable with,” Redman said. Better the devil you know?
The Tier 1 suppliers, in turn, backed LTE over WiMAX because they saw that, for a variety of reasons, they could make more profit selling LTE. “In many cases, it was more a political decision than one based on technology or cost,” he said.
Redman has reportedly gone as far as urging businesses to hold off on investing in WiMAX, at least until the equipment ecosystem evolves to make dual-mode 3G-WiMAX devices more readily available.
This enraged some elements in the WiMAX camp. One Intel blogger characterized Gartner’s analysis of the market as “the most recent attempt at ‘drive-by kneecapping’” of the technology.

Going to market
That said, he too believes WiMAX will have a tough time overcoming market factors arrayed against it. He argues that LTE will be building from a customer base of 4.6 billion mobile users worldwide, while WiMAX mainly has appeal as a replacement for DSL, especially in developing markets where wireline broadband technologies are not available. It will be building from a much smaller base: fewer than a billion customers worldwide.IDC will publish a forecast later this year showing sales of LTE equipment surpassing WiMAX equipment sales some time in 2012.

WiMAX vs LTE: The 4G Wireless Network Battle
Remember when 3G was the future of wireless data? It’s not even universally available in the U.S. yet, and the race is already well underway to replace it. WiMAX, the 4G network technology that counts Sprint and Intel among its boosters, has a head start. But it’s losing ground to Long Term Evolution (LTE).
LTE’s promise of high-speed, two-way wireless data promises an “all-IP” mode of communications in which voice calls are handled via VoIP. It’s also designed to handle video well, and to permit roaming through multiple systems–from cellular to Wi-Fi and satellite.
LTE is considered by many to be the obvious successor to current-generation 3G technologies, based on WCDMA, HSDPA, HSUPA and HSPA, in part because it updates UMTS technology to provide significantly faster data rates for both uploading and downloading, while preserving backwards compatibility with existing handsets based on older standards. Verizon Wireless, has already said that it will support LTE as its 4G technology of choice, abandoning its current CDMA based network.
Speed, theoretically superior to WiMAX, would give LTE an edge for bandwidth-hungry applications such as live TV and video downloads. LTE handsets are also expected to embrace automatic roaming to non-cellular systems, such as Wi-Fi and satellite.
It’s true that WiMAX, unlike LTE, is available today–but it’s only in the early stages of rollout. (Sprint-backed Clearwire, the only company to roll out WiMAX in the U.. to date, offers service only in scattered areas in sixteen states.) Analysts express doubts that phone manufacturers, networking companies, app developers, operators, and carriers will ever make WiMAX a popular replacement for 2G or 2.75G facilities and services.
Still, WiMAX may endure–Clearwire has vowed to build a nationwide network. But the leisurely pace of its rollout indicates extra caution about the necessary investments. And Clearwire is controlled by Sprint, widely considered the weakest of the major U.S wireless carriers.
Whether they bet on LTE, WiMAX, or some combination of the two, major carriers, hardware companies, and other telecommunications players cannot postpone decisions about their 4G plans–even though it’s not yet clear how the competing technologies will sort themselves out. Investing mammoth amounts of money on building out what may be a temporary technology is high risk–especially during the worst economic crisis since the Great Depression–but they can’t leave the market open to their competitors.
The matter of superiority, WiMAX vs. LTE, is mind-boggling to industry observers, even if it might not be to a genius, or to electrical and wireless engineers. Innovation advocates might see LTE as a natural evolution of technology. Yet some technology writers have described it as unusual, in the logical sequence of technological advancement. At least, the adoption of LTE shows that the best decision, in the acceleration of wireless-connectivity technology, is not to wait for the economic recession to hit rock bottom or reverse.
The CTIA Wireless trade show in Las Vegas last month made the industry’s 4G road map a bit clearer. Most players, including Motorola and Verizon, said that they would go straight to LTE without touching WiMAX. Nokia, went further: According to a Financial Times report, Anssi Vanjoki, Nokia’s head of sales and manufacturing, compared WiMAX’s prospects to those of Betamax.
Worldwide, LTE’s prospects look promising. Some observers say that China will go directly to LTE, bypassing WiMAX. Major Chinese telecommunications players, including China Mobile and Huawei, are believed to be working hard to step up to LTE in a year or two.
Pakistan, would also benefit from LTE. Currently, almost all the mobile operators, including the formerly state-owned landline monopoly Pakistan Telecommunication Company (PTCL), have flooded the consumer market with phones, cameras, music players, and USB modems that use a form of connectivity that’s similar to WiMAX but slower. These devices in Pakistan offer Internet connectivity of 300-kbs. Companies such as Wateen Telecom of the United Arab Emirates have tried to offer WiMAX, but without much success; but hardly succeeded; PTCL has tried a package of cellular connectivity, satellite TV, and broadband Internet that is also far from a success so far. China Mobile is one of the five major mobile operators in Pakistan, and other Chinese companies such as ZTE and Huawei are major players, so Pakistan’s 4G future will likely mirror that of China.
Countries such as Sweden and Finland, which are small but well-developed and technology-rich can benefit from this transitional period of wireless technologies, during which 3G, WiMAX, and LTE will coexists. Examples could be Sweden, with rich file-sharing experience, and Finland, with Nokia having early experimentation on real time interactive videos. Next in line are rapidly developing countries, including China, India, and Pakistan.
The U.S., a traditional leader in innovation and technological advancement, may struggle to adopt 4G as rapidly as other countries. Why? One reason is the difficulty of ramping up LTE during a period of recession. Another is the indecisiveness of U.S. industry heavyweights about next-generation standards. But even if the U.S.’s 4G future is somewhat murky, wireless connectivity is bound to evolve towards higher speed, great traffic capacity and more reliable connections.

Malaysian broadband information
In Malaysia, we have both wired and and wireless broadband internet connectivity. We might used it in our daily life, but some of us might not know which technology of broadband he/she is using. Following is the list of all the broadband internet technology used in Malaysia:
Wired
Wireless
- Wimax - currently used by packet one(P1), YTLcomms, AMAX, REDtone
- HSPA - known as 3.5G, currently used by MAXIS, Celcom, DiGi, UMobile
- LTE - known as next generation of hspa by 3gpp, theoretically can up to 100Mbps download and 50Mbps upload.
- iBurst - currently used by izzi
Both wired and wireless broadband have their pros and cons, for user who prefer fast speed, stable connectivity and low latency must opt for wired broadband, for user who want mobility then opt for wireless broadband.
Of course you cannot compare directly between wired and wireless broadband. Wireless is transferring data over the air which will have interference, but this will not happen for wired broadband. Anyway, I believe the trend in moving into wireless. Just like our home-line, everybody is changing into mobile phone nowadays.

WiMax Vs LTE : future mobile communication trend ?
After a long debut about the next-generation cellular and WiMax deployment in the near future for the new communication module, seems they will show something to us, LTE and WiMax for future communication module. Both are still struggling to prove their capability, performance reliability and signal efficiency towards higher bandwidth requirement from community. Whihc one will win the segment? However, before we further jump into conclusion, some clarification need to be mentioned here. There are still some people really confused about those two; what are they? what they do? how great performance they can produce? how reliable they are?..Well, if we put these two together, they are almost the same. First, both are 4G technologies designed to move data rather than voice. Both are IP networks based on OFDM technology for fixed (802.16) and OFDMA (802.16m & LTE) for mobile — so rather than rivals such as GSM and CDMA, they’re more like siblings. But does the siblings all the same. no right? So, there a plenty of difference among them.
WiMax is based on a IEEE standard (802.16), and like that other popular IEEE effort, Wi-Fi, it’s an open standard that was debated by a large community of engineers before getting ratified. In fact, we’re still waiting on the 802.16m standard for faster mobile WiMax to be ratified. The level of openness means WiMax equipment is standard and therefore cheaper to buy — sometimes half the cost and sometimes even less. Depending on the spectrum alloted for WiMax deployments and how the network is configured, this can mean a WiMax network is cheaper to build. The speed for the WiMax (802.16) is up to 70 Mbps, while the mobile WiMax (802.16m) is up to 100Mbps.
Malaysia is still in progress in deploying WiMax Technology, but the condition is stillon “testing” for so long . Do not know why. Izzi is a new name in Malaysian Broadband challange and the claim to have 4G connection. Check it first before you subscribe (affraid only for the best effort - as another slumpy monopoly carrier advertise their broadband). Sprint Nextel will aslo deploy this WiMax technology to become their 4G carrier.
Whilst, The LTE, (3GPP Long Term Evolution), is the next-generation network that beyond 3G. In addition to enabling fixed to mobile migrations of Internet applications such as Voice over IP (VoIP), video streaming, music downloading, mobile TV and many others, LTE networks will also provide the capacity to support an explosion in demand for connectivity from a new generation of consumer devices tailored to those new mobile applications. Most of the Telcos believes LTE will be the standard chosen by 80 percent of the carriers in the world
LTE is the natural evolution of 3GPP GSM and WCDMA networks. It is also an evolution candidate for 3GPP2 CDMA networks. Efforts are underway to harmonize the standards. LTE itself is a new paradigm in access, with a new modulation technique, OFDM (Orthogonal Frequency Division Multiplex) or some people said it use Orthogonal Frequency Division Multiple Access (OFDMA), and antenna technology, MIMO (Multiple Input Multiple Output).
Nortel, Nokia , LG, and Alcatel-lucent are among the group who perform test on LTE deployment.
To much technical right?
The funny thing about technology businesses is that technology counts for so little in the final result. Politics, human nature, and all of the frailties inherent therein trump the technology issues in virtually every case. So, logically: LTE will win.
The cellular carriers control the market, so they control the decision. Now if the WiMAX camp could come up with something that was phenomenally better, then the cellular carrier would have to look more closely at this, but unfortunately, physics works the same for everyone. With no compelling technical advantage for WiMAX, LTE will win. Agree?
