The spaces between us

Lei Yang, Ben Y. Zhao, Haitao Zheng
2010 Proceedings of the sixteenth annual international conference on Mobile computing and networking - MobiCom '10  
As more devices in a given area are packed into orthogonal wireless channels, choosing the right guardband size to minimize cross-channel interference becomes critical to network performance.  ...  Using both WiFi and GNU radio experiments, we show that the traditional "one-size-fits-all" approach to guardband assignment is ineffective, and can produce throughput degradation up to 80%.  ...  Any opinions, findings, and conclusions or recommendations expressed in this material are those of the authors and do not necessarily reflect the views of the National Science Foundation.  ...
