Exploding Aardvark

US communications outfit Sanswire yesterday unveiled concrete evidence of its truly audacious plan to deliver line-of-sight wireless broadband and mobile phone signals to an area the size of Texas from a single transmission point. The company is not, however, planning a private satellite launch or 10,000-foot-high transmission mast disguised as a really big tree — rather it intends to deploy a fleet of geostationary, robotic airships hovering at a comfortable 65,000 feet above the Earth.
