As an enabling step, the CAPANINA first year trials (carried out at Pershore, Wiltshire,
UK) used a lower altitude tethered platform from which a series of critical radio and optical
communications tests were carried out. SkyLINC Ltd , one of the UK based partners, successfully
established a tethered aerial platform and implemented several preliminary radio frequency tests
to and from the balloon. BTExact (part of BT) were able to utilise 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
(Backhaul). This is an essential link in the chain to provide broadband wireless radio communications
from HAPs to large numbers of users on the ground.
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 High Altitude Platforms placed in the stratosphere at altitudes of
around 20km such that one platform can serve a region around 60km across.

| ||BROADBAND |
Broadband internet access could soon be two hundred times faster than current speeds.
The Capanina Research Project, led by scientists in York, also aims to extend broadband
access to rural communities and even moving trains thanks to High Altitude Platforms -
airships or solar-powered gliders in the sky.
Dr David Grace explains how they could work.
