Assessing channel conditions is critical to routing and MAC protocols. But, this task is challenging due to the highly dynamic nature of wireless channels and the characteristic differences between indoor and outdoor environments. This paper presents observations and analysis from extensive measurements on IEEE 802.11g channels indoor and outdoor. The experiments are designed to investigate the channel dynamics through metrics such as successful frame delivery rate, loss rate, and Signal-to-Noise Ratio on IEEE 802.11 networks. The objective of this work is to reveal the interaction between these metrics and their variations in time and space.
