In this paper, we address the following question: given a typical indoor IEEE 802.11 mesh network, how are carrier sensing, receiving and interference range related and how stable are they in time? To answer this question, we conducted broadcast measurements in the Berlin RoofNet testbed under saturated conditions using multiple simultaneous transmitters with either carrier sensing turned on and off, respectively. In contrast to several prior studies, our results indicate that wireless mesh networks are much more deterministic, and they show a high stability even under self-induced interference. Interestingly, for IEEE 802.11b at 1Mbps, the interference range of a transmitter is only slightly larger than its receiving range. On the other hand, the carrier sensing range is slightly smaller than the receiving range. In particular, a packet success rate around 10% is a reasonable good indicator for carrier sensing. In addition, we identified uncontrolled external interference and environmental mobility as the key disturbing factors causing variations in packet reception.
