According to its “WiMax in emerging markets : the opportunity assessed” report, Ovum reckons that WiMax might face a tough time to become the only next generation mobile data access platform in developed regions like Europe and Asia.

Despite the low fixed-line penetration in developing nations, factors such as cost, coverage, vendor support and service provider choices will hinder uptake of the wimax technology, although that is not expected to impact the distribution of these networks in the short term.

“Two thirds of the 300+ WiMax networks globally are in the emerging markets of Africa, Asia, Eastern Europe, Middle East and Latin America,” said Angel Dobardziev, practice leader at Ovum.

As of August 2009, Russian operator Scartel is the first emerging WiMax player to have hit the 100,000 subscriber mark, ahead of Packet One in Malaysia with 80,000. The problem, it seems, is that the harsh economic climate makes it difficult for these companies to get the funding required to roll them out to the greenfield locales where they would be more competitive.

The report doesn’t mention whether WiMax’s biggest rival, long term evolution (LTE), might suffer the same fate. But as it is starting to reach the point of significant trials with rollouts expected in the not too distant future, arriving late to the party might actually be a good thing for the technology as signs of slow recovery are starting to appear and demand for mobile data access is starting to approach the limits of what current platforms can deliver.… Read the rest

­Australian WiMAX network operator, BigAir Group is expanding its network after signing a supply contract with Airspan Networks, reported Cellular News.

Following successful deployments in Melbourne and Sydney, BigAir is continuing to use Airspan WiMAX equipment to expand its service offerings into the Perth, Adelaide, Brisbane and Gold Coast markets in the 5.8 GHz and 5.4 GHz frequency bands.

BigAir first selected Airspan in 2007.

“BigAir has been very successful in serving our customer base,” said BigAir CEO, Jason Ashton. “We own and operate Australia’s largest fixed wireless next-generation broadband network which now covers the six largest cities in Australia. Utilizing Airspan’s solution allows us to offer our customers higher speed, greater reliability and lower-cost broadband services.” In addition to the WiMAX solution, BigAir is using Airspan’s FlexNET backhaul solution for higher point-to-point bandwidth requirements.

Financial and timelines for the contract were not disclosed.… Read the rest

Asia-Pacific

The Asia Pacific region keeps leading the world in WiMax innovation, as countries like Japan, India and Korea continue to invest in the technology, with maverick operators in neighboring countries following suit, industry analyst firm Frost & Sullivan reported recently.

However, China recently refused to license WiMax in its area, the firm said. “The fact that China has not supported WiMAX, preferring instead to back the homegrown TD-SCDMA 3G standard, is particularly unnerving for the technology’s prospects in the region,” said Shaker Amin, industry analyst, Frost & Sullivan. The irony is that Chinese infrastructure giants Huawei Technologies and ZTE are two of the world’s largest WiMax vendors. “”Even grimmer still, important markets such as India and Thailand, both of which also hold great potential for WiMAX, have fallen behind in issuing WiMAX licenses and spectrum allocation in the 2.3 and 2.5GHz bands,” Amin added.

Aside from sluggish adoption in some countries, Amin added that weak operator support, high equipment prices, and HSPA (High-Speed Packet Access) and LTE (Long-Term Evolution) competition continue to plague WiMax adoption in Asia Pacific.

Despite these setbacks, the firm estimates the subscriber base in the region to amount to 24 million by 2014, with revenues of up to $6.4 billion. “We believe that the region holds the best prospects for WiMAX services in terms of subscriber uptake and future innovation,” said Amin, adding that much of Asia-Pac, compared to the rest of the world, still lack 3G spectrum and broadband connectivity.

For this reason, Amin noted that it’s now or never for operators to adopt WiMax. “We believe that the key focus of WiMAX will be to provide basic data connectivity in underserved markets at around the 1Mbps level, and as a precursor or complement to HSPA and LTE technologies where spectrum is scarce,” he explained.… Read the rest

wimax-jobs-new-york

Clearwire appears to be gradually moving ahead with plans to deploy mobile WiMax in the New York area, although building out this market could take up to two more years.

Since January 2009, the company has posted job ads looking for RF Engineers, Operation Managers in the New York and New Jersey area. Clearwire isn’t yet making any official statement on a potential New York deployment. Before the merger of the Sprint Nextel Corp. and Clearwire WiMax assets, Samsung had signed a deal to deploy WiMax in NYC with Sprint.

In general, the New York area hasn’t been having much luck when it comes to wireless broadband deployments.

Clearwire has just launched WiMax in Salem, Ore., under its “Clear” brand, and will continue to roll out the technology this year. Clear.com recently updated its coverage maps to reveal that Philadelphia now gets Clear Wimax and becomes the first big metro area to get Clearwire’s WiMAX services.

WiMax is different from WiFi in that its range is no longer a few feet, but can carry over distances as long as 30 miles. (Learn more about WiMax in FAQ section)… Read the rest

wimax

Government agencies and other organizations planning to use WiMAX networks can get technical advice on improving the security of their systems from a draft computer security guide prepared by the National Institute of Standards and Technology (NIST).

WiMAX is a wireless protocol that can cover an area that incorporates a few miles such as a campus or small town. It has a larger reach than the more familiar “WiFi” networks used in offices or homes, but smaller than wireless areas covered by cell phones. The technology, guided by standards issued by IEEE, originally was designed to provide last-mile broadband wireless access as an alternative to cable, digital subscriber line (DSL) or T1 service. In recent years its focus has shifted to provide a more cellular-like, mobile architecture to serve a broader audience.

WiMAX was used after the December 2004 tsunami in Aceh, Indonesia after the communication infrastructure was destroyed and also after Hurricane Katrina along the coast of the Gulf of Mexico.

Special Publication 800-127 “Guide to Security for WiMAX Technologies” discusses WiMAX technology’s topologies, components, certifications, security features and related security concerns. It covers the IEEE 802.16 standard for WiMAX and its evolution up to the 2009 version.

The main threat to WiMAX networks occurs when the radio links between WiMAX nodes are compromised. The systems are then susceptible to denial of service attacks, eavesdropping, message modification and resource misappropriation.

SP 800-127 recommends taking advantage of built-in security features to protect the data confidentiality on the network. It also suggests that organizations using WiMAX technology should:

  • Develop a robust WiMAX security policy and enforce it.
  • Pay particular attention to WiMAX technical countermeasure capabilities before implementing WiMAX technology.
  • Use WiMAX technology that supports Extensible Authentication Protocol methods as recommended in NIST SP 800-120 (available here)
  • Implement Federal Information Processing Standards-validated encryption to protect their data communications.

The draft version of NIST SP 800-127 is open for public comment through October 30, 2009. The document is available online at csrc.nist.gov. Comments should be addressed to 800-127comments@nist.gov with “Comments on Public Draft SP 800-127″ in the subject line.… Read the rest

ITU-TELECOM-WORLD-2009

The WiMAX Forum and executives from Clearwire, Beceem, Cisco, Huawei, Samsung, Intel, UQC, Yota and others were all on-hand at the ITU Telecom World 2009 conference, held in Geneva, Switzerland to show support for WiMAX in the 4G race.

Barry West recently wrote a blogpost about the event on the Clear Blog :

In the evolution of any species or technology, it is the strongest and fastest and most capable that perseveres. This week, I had the pleasure of joining our fellow WiMAX champions at the, where it became clear to me that WiMAX still has a leg-up in the evolutionary race to the 4G finish line.

Already at 500 deployments across more than 145 countries, WiMAX is showing it has the chops to maintain its market lead as the first commercially available 4G technology worldwide.

And Clearwire has recently taken several critical steps. With last week’s announcement of new infrastructure partnerships with Alvarion and ZTE to build out WiMAX in Spain; recent agreements with Russia’s Yota and Japan’s UQ Communications; and with the robust vendor structure in place throughout North America, Clearwire is certainly driving the evolution of the WiMax technology forward.… Read the rest
