WiMAX Is 3G

WiMAX has a reason to celebrate. The International Telecommunications Union has just approved the non-cellular technology as part of a 3G standard. This means that operators with 3G spectrum in their 2.5 GHz bands globally can use WiMAX to build out a spectrum.

The last interface added was back in 1999 when ITU added IMT-2000 as it established the original technologies. IMT-2000 and five other cellular standards had to be used in the 3G standard, now the door is open to WiMAX.

But all is not rosey for WiMAX, the debate between technologies is far from over.

Mobile WiMax Vs. 3G: Will Faster And Cheaper Win?

Though no one contests that mobile WiMax has been gathering momentum, some doubt whether the technology will deliver what it promises in terms of performance. Sprint Nextel believes its mobile WiMax network, which it will roll out in 2008, allows for download speeds of 2 Mbps to 4 Mbps and upload speeds of about 1 Mbps on the average.

According to Kerton Group principal Derek Kerton, the success of WiMax will depend on whether it can address issues such as in-building penetration and power consumption, which its backers regard as insignificant. Ali Tabassi, Sprint Nextel’s vice president of technology development, conceded that like any wide-area wireless technologies, WiMax is not immune to in-building penetration problems. The company, however, houses a special group that has solved these issues for its cellular voice and data service, to apply its expertise to the mobile WiMax network.

Kerton admitted that Sprint has the right strategy of creating an ecosystem of products and services based on the technology. The company has contracted Motorola, Samsung and Nokia to provide equipment and handsets for its service. Intel already announced it would release chips that will have both WiMax and WiFi capabilities. Tabassi, however, could not say when these devices will be available. He expects PCMCIA cards and modems to appear in the market when Sprint carries out its launches in two markets. Samsung, he said, may come out with a dual-mode phone by the end of the year.

Mobile Operators Defensive Over 3G Auctions

UK’s 3G market is circumspect over Ofcom’s announcement on spectrum auction. The public sale, the first in six years, will involve the 2500-2690 MHz band, which the British regulator deemed compatible with 3G and mobile WiMax.

Although stating that it welcomed the proposal, O2 urged Ofcom to retain its current condition demanding that 3G operators extend service to 80 percent of the population. The company, along with Vodafone, urged the agency to study whether 3G services can tap the 2G spectrum, which could expand their cell sizes and allow them to provide better service to their clients. Ofcom chief technologist William Webb believed “refarming” spectrum is not feasible at the moment. According to Webb, such move could lead to competitive imbalances.

Pipex, meanwhile, supported Ofcom’s plans and expects new entrants and traditional players to bid for spectrum. Graham Currier, the ISP’s business development director, said there is high interest in the event among companies hoping to deploy WiMax. He declined, however, to confirm that Pipex, which is partly owned by WiMax champion Intel, will participate in the auction and state the company’s plans concerning WiMax.

WiMAX May Challenge Asia 3G ‘In Five Years’

Analysts believe it will take another five years for WiMax to challenge 3G in the Asia Pacific region. According to In-Stat analyst Bryan Wang, WiMax users will grow to 14 million by 2011. This is just about 8 percent of the Asian 3G market by that time, as per the prediction of Frost & Sullivan research analyst Lenny Koay. The popularity of 3G, Koay said, will continue to rise in five years, with the number of users reaching 178 million by the end of 2011. Most of the growth will be seen in China and India as 3G services are expected to hit both markets next year.

Analysts say a lack of awareness in data services and the unimpressive revenues from mobile solutions play a role in the tepid WiMax uptake. Interoperability issues and lack of standardization, according to Wang, also hamper widespread acceptance of the technology.

Why Sprint Says WiMax Is 4G

Sprint CTO Barry West regards WiMax the 4G technology because not only is it faster, it is also cheaper. According to West, WiMax causes a 10-fold improvement in the price-per-bit as it uses a wider channel. The current CDMA networks run on a 1.25-MHz channel and can deliver a maximum of 4 bits per hertz, or around 5Mbit/s at the base station. WiMax, on the other hand, makes use of a 10-MHz channel, thus it can generate a total of 40Mbit/s.

Switching From Cell To Wi-Fi, Seamlessly

T-Mobile USA is due to begin offering a new service for mobile phone users that will allow seamless switching between its cellular network and their home Wi-Fi networks. The company will use unlicensed mobile access or UMA to enable the new service. T-Mobile, several blogs reported, has performed a trial of the service in the Pacific Northwest for a month. Kineto Wireless, one of the companies developing software to support the new product, expects T-Mobile to offer the service to users in at least one major city initially and expand the coverage to include the firm’s 7,836 hot spots nationwide.

Virgin Trains Get Connected With WiMax And HSDPA

Virgin Trains has elected to use WiMax to enable passengers get Internet connection from their seat. QinetiQ Rail is providing the technology and has installed it on the company’s Pendolino train. CEO Magnus McEwen-King expects the application of the WiMax-and-satellite combination to bring down costs. “If we were to use WiMax throughout the whole route - for the west coast mainline, that would be 1,500km - it would be very expensive. WiMax will be used in urban areas and satellite will give us 90 per cent of our reach,” McEwen-King remarked. The system, according to QinetiQ Rail, can deliver a connection of up to 49Mbps for trains moving at up to 200kmph, but with satellite downlink the speed will be around 20Mbps.

Analysts Split Over HSDPA Vs WiMax

Ovum analyst Julien Grivolas expects faster third-generation mobile services to become mainstream consumer service by 2008. The analyst firm believes users of High-Speed Downlink Packet Access (HSDPA) in Western Europe will grow to 16.5 million in two years and 50 million through 2010. Grivolas ascribed the high estimated uptake to the reality that HSDPA recycles the spectrum already utilized for 3G base technology, Universal Mobile Telecommunications System. This development, he said, could dampen the pace of adoption of WiMax. “In areas where HSDPA becomes widely available, like Western Europe, and where well-suited spectrum for 802.16e [mobile WiMax] is rare, the window of opportunity for mobile WiMax will be quite limited,” Grivolas remarked. Dean Bubley of Disruptive Analysis disagreed with Grivolas’ view, saying that WiMax would enjoy more success because it will not necessitate a backhaul upgrade to maximize the high speeds that it can deliver. In addition, “many cellular operators have a Walled Garden mindset, whereas possibly mobile WiMax plays better to the 21st century view of the world, where connectivity and services should be decoupled,” he stated.

WiFi Versus 3G: Let Battle Commence!

With the increasing use of wireless networks, experts are debating which technology, Wi-Fi or 3G, would be the best option. The Cloud chief operating officer Bobby Sarin believes laptops and devices would soon be able to use both types of networks but it would all depend on the cost. Toby Wright, who heads the content technology services for Reuters in Europe, said reliability is more important than network speed, thus making 3G/GPRS a better choice than Wi-Fi because this would ensure that users will still have connection even when they are away from city hubs. Anurag Lal, senior vice-president for business development at iPass, expects laptops and devices with multi-mode capability to soon enable users to move between HSDPA, Wimax, and Wi-Fi networks without difficulty. But this may not be that easy for enterprises wanting to cut their mobile phone bills through the use of dual-mode handsets as “operators will configure handsets to always prefer a cellular connection,” according to Lal.
