ALSO: A new report from Research and Markets says that the BWA/WiMAX market in Brazil is poised for impressive growth. In 2005, the BWA equipment market opportunity was a mere $6 million, dominated by deployments of unlicensed 5.8 GHz equipment by WISPs and corporate users. R&M says that with the upcoming auction, the certification of new equipment and lower-cost equipment, the annual 3.5 GHz equipment opportunity will increase from $1 million in 2005 to $33 million in 2010. The 2.5 GHz market opportunity will also become substantial, with shipments projected at $31 million by 2010. Overall, the total accumulated equipment market for BWA/WiMAX in Brazil should reach $300 million by 2010, which makes Brazil a key market for BWA/WiMAX vendors for years to come. R&M projects an accumulated 768,000 subscribers by 2010 among residential and business users. WiMAX subscribers should represent two-thirds of this figure. Approximately 70 percent of the WiMAX subscribers will be mobile customers who are predominately residential, while fixed WiMAX will continue to be driven by large corporations followed by SME customers.
