Setting scene for TV white spaces and dynamic spectrum access in South Africa

Abstract

In this paper an overview of the TV white space technology and dynamic spectrum access is presented with the aim of improving the capacity of wireless broadband connectivity of communities in emerging markets. The paper proposes that large chunks of TV white space spectrum should be allocated for un-licenced but managed use for improved wireless internet connectivity. Various pilot trials which are planned to test the technology of white spaces without incurring undue interference to incumbent broadcasters, are discussed, with respect to a planned pilot trial in South Africa which is the first of its kind in Africa. TV white space monitoring trials based on a cognitive radio testbed and spectrum data base development performed in rural and urban settings in South Africa are also presented, with the aim to test the suitability of the technology and initiate possible regulatory intervention for the use of TV white space technology for improved broadband connectivity.
