ABSTRACT
The demand for high-capacity wireless services is bringing increasing challenges, especially for delivery of the ‘last mile’. Terrestrially, the need for line-of-sight propagation paths represents a constraint unless very large numbers of base-station masts are deployed, while satellite systems have capacity limitations. An emerging solution is offered by high-altitude platforms (HAPs) operating in the stratosphere at altitudes of up to 22 km to provide communication facilities that can exploit the best features of both terrestrial and satellite schemes. In this paper we outline the application of airships as low cost alternative for HAPs for delivery of future broadband wireless communications.
