The Spaces Between Us: Setting and Maintaining Boundaries in Wireless Spectrum Access

Guardbands are designed to insulate transmissions on adjacent frequencies from mutual interference. 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, the authors' show that the traditional "One-size-fits-all" approach to guardband assignment is ineffective, and can produce throughput degradation up to 80%.
