Theorists and practitioners have fairly different perspectives on how wireless broadcast works. Theorists think about synchrony; practitioners think about backoff. Theorists assume reliable communication; practitioners worry about collisions. The examples are endless. Our goal is to begin to reconcile the theory and practice of wireless broadcast, in the presence of failures. We propose new models for wireless broadcast and use them to examine what makes a broadcast model good. In the process, we pose some interesting questions that will help to bridge the gap.
