In this paper, the authors address the impact of ACI on dynamic spectrum allocation in multi-radio systems. In particular, they present the benefits of dynamic spectrum allocation by adapting channel width and distance in order to mitigate ACI in multi-radio mesh networks. Based on their measurement campaign in an indoor mesh testbed, which they extended in order to use adaptive channel width, they evaluate the performance in terms of network throughput. They show that by using channel width adaptation and antenna separation, the impact of ACI can be significantly reduced. The performed experiments give important insights into ACI in multi-radio cognitive systems which help to develop e.g. better channel assignment algorithms or capacity estimation methods.
