For the design and evaluation of wireless MAC and link layer protocols it is desirable to have some knowledge about the error patterns delivered by the wireless PHY. One way to obtain this knowledge is to perform measurements. In this paper we report on measurements taken in two almost ideal environments (no interferers, simple propagation environment) and using an IEEE 802.11 DSSS-Compliant physical layer (PHY). These measurements highlight the influence of selected parameters (Diversity, Distance) and can serve as “baseline” measurement for further studies.
