Now the consortium plans further trials, testing the feasibility of using high-altitude aerial platforms - airships or solar-powered aircraft - to bring broadband Internet to remote rural areas and even fast-moving trains.
The technology will provide broadband services which are 200 times faster than current services.
Researchers ran the trials, using a tethered balloon at a former RAF airfield at Pershore, Worcestershire, to show that it is possible to use mm-wave band (28/31GHz) and very high data-rate optical communication systems from aerial platforms.
High rate data systems allow more information to be moved in less time, making downloading a file, movie, photographs and music much faster.
SkyLINC Ltd, one of the UK-based partners in CAPANINA, successfully set up a tethered aerial platform and made several preliminary radio frequency tests to and from the balloon. BTExact (part of BT) were also able to use the platform to trial several broadband applications, such as video on demand and high-speed Internet.
To conclude the tests, DLR, a German-based partner, carried out some critical optical communication tracking tests. Optical techniques offer very high data-rate communications and are being developed to provide links between two aerial platforms, or between an aerial platform and a ground station.
CAPANINA aims to deliver wireless broadband at speeds of up to 120Mbits/second from aerial platforms such that rural, suburban and moving users can have cost-effective broadband communications. The ultimate aim is to have a number of the platforms in the stratosphere at altitudes of around 20km with one platform serving a region of approximately 60km.
Spurred on by the successes further trials using higher altitude platforms are planned involving CGS from Italy and NICT from Japan.
