GlobeTel Communications will buy HotZone, which is already developing a Stratellite for GlobeTel subsidiary Sanswire.
It will put a WiMAX base station in an airship at an altitude of 20 kilometers. The coverage area is 300,000 square kilometers (about the size of Poland - not bad!).
Of course this is an as yet unproven technology, not to mention the business case. Interesting stuff, though, for looking at what WiMAX will be capable of.
