The Asia-Pacific market will account for 45% of the world’s total WiMAX user base, according to a new report from In-Stat. "WiMAX in Asia” forecasts WiMAX subscriber growth in the market to reach 3.8 million by 2009.

Several other analysts also have predicted that it could be several years before WiMAX becomes a viable access service worldwide, though the technology will be useful in transport and backhaul applications.

"Issues that may hamper the adoption of WiMAX networks in the region include spectrum regulation that varies significantly across countries and competition on mobility from other technologies," according to Bryan Wang, an In-Stat Content Manager based in Asia. "Meanwhile, fixed wireless operators are not very enthusiastic about WiMAX after having been burned by last-mile promises in the past. Vendors need to recruit a few high-profile operators to build real-world success stories early on."

Wang's research found that South Korea is estimated to contribute over 40% of the regional WiMAX equipment revenue in 2009, followed by China with 34% and Japan with 17%. Also, by 2009, Asia/Pacific WiMAX equipment spending will account for US$1,988.2 million, the report states.
