The cognitive paradigm allows exploiting spectral resources, generally allocated for licensed systems, as ‘secondary’ users. When this paradigm is applied to television broadcasting, the unused frequencies are called ‘white spaces’. In this work we reports some experimental results of a 802.11-based system that uses a ‘white space’ for providing a bidirectional service in order to overcome the digital divide problem in an alpine valley.
