As we noted last week, how well WiMax is doing depends who you ask, and if you ask the WiMax forum (comprised largely of WiMax vendors), WiMax is doing very well. In a new report, the group breaks down WiMax deployment globally, noting that WiMax deployments reach 620 million people worldwide, a total the group says will surpass one billion by the end of 2011. In North America, where the totals are lowest in the world, the forum says there now 47 million people covered by 51 deployments. Of course the majority of those deployments are courtesy of Clearwire, which hopes to reach 120 pops and 120 million users by the end of 2010. If you're interested, the WiMax forum also offers a Google Maps breakdown of all global deployments.
