Assessing the Worldwide Potential for WiMAX
Broadband wireless’ watershed
by Mo Shakouri
The opening of the WiMAX Forum certification testing laboratory at Cetecom in Malaga, Spain last July marked a milestone leading to the availability of WiMAX certified products for broadband wireless access.
Initial products will conform to the IEEE 802.16-2004 air interface standard addressing fixed and nomadic services with WiMAX-defined performance profiles in the 3.5 GHz licensed frequency band and the 5.8 GHz unlicensed band.
Other frequency bands expected to be covered following these initial products are the 2.5 GHz MMDS band and the 4.9 GHz public safety band. WiMAX-certified products in these bands will assure worldwide applicability of the WiMAX technology by addressing spectrum allocations that vary country by country.
Meanwhile, the WiMAX Forum continues to move forward with the IEEE 802.16e air interface standard to address portable and mobile applications. This standard is expected to be ratified later this year, paving the way for WiMAX-defined profiles and certification testing likely to begin in 2006.
This amendment will add portability and mobility to the suite of applications covered by the 802.16 standard. WiBro, being introduced in Korea this year, is also based on 802.16e.
WiMAX End to End
Point-to-multipoint (PMP) wireless solutions based on WiMAX address the performance and economic challenges associated with providing cost-effective broadband access in the infamous last mile.
