Abstract
Seamless redundancy can be profitably exploited to improve predictability of wireless networks, including IEEE 802.11. Packets are sent on two channels at the same time and duplicate copies are discarded by receivers. As long as behavior of channels is reasonably uncorrelated, both transmission latencies and the frame loss ratio improve noticeably. In this paper, such an assumption has been analyzed by means of experimental measurements carried out on real devices. Results confirm that, in typical operating conditions, independence reasonably holds.
