A lot of attention has been given to multi-hop wireless networks lately, but further research is needed. This attention has motivated an increase in the number of 802.11- based deployments, both indoor and outdoor. These testbeds are used to run measurements in order to analyze and understand the limitation and differences between analytical or simulation-based figures and the results from real-life experimentation. In this paper, the authors describe the lessons learned from the deployment of a wireless multi-hop testbed under the false floor of a laboratory in their Computer Science building. They assess the radio shielding provided by the false floor panels, and run exhaustive and controlled experiments to analyze the performance limits of commercial off-the-shelf hardware.
