A low cost and power efficient TV white space technology solution for future rural broadband access networks

Wireless radio links present one option for rural broadband where population is sparse and many of the existing technologies such as optical fiber or broadband via DSL are not economical due to rugged/mountainous terrain. In this paper, we present a broadband test bed running in the Scottish Highlands and Islands, which is based on a relay network of low-power and cost efficient base stations. In addition to a 5GHz network, the test-bed also provides an overlay UHF white space network sharing the same infrastructure. The low-power base stations forming the relay nodes are supplied by wind and solar energy, establishing a green technology with low requirements on planning permission. Overall, the system offers a robust and independent medium to support broadband communication in rural settings.
