Abstract: Ultra-wide bandwidth (UWB) systems allow for accurate positioning in environments where global navigation satellite systems may fail, especially when complemented with cooperative processing. While cooperative UWB algorithms have led to centimeter-level accuracies, the communication overhead is often neglected. In this talk, we quantify how positioning accuracy and medium access delay trade off and derive an asymptotic scaling of accuracy and delay. Surprisingly, our study indicates that in some conditions, standard cooperation offers the worst possible trade-off.
