802.11 based outdoor community mesh networks have seen several deployments in the last few years. Prior link- level studies focus mostly on 802.11 b links, and a systematic and detailed link-level study of 802.11 g is lacking. In this paper, we present a study of the link error rate as a function of the RSSI; we closely examine the RSSI threshold beyond which the link error rate is negligible. Our...
Wireless mesh networks (WMNs) support a variety of modulation and coding schemes (MCSs) and hence enable adaptive modulation and coding. On the one hand, adaptive modulation and coding significantly increases the overall system capacity, as it allows to maximize the throughput on each link in dependence of the channel conditions. On the other hand, there is a trade-off between link data rate and spatial...
