Talk title: Bit-error analysis in WiFi networks based on real measurements

Abstract: The IEEE 802.11 standard is coming from 1999. Since that time lots of research paper were born analyzing WiFi networks. However, until the recent years, WiFi devices and drivers were on closed source, so measurements could rely only on those features that the vendors offered for them. For such reason there could be hardly any research focusing on the bit level internals of WiFi transmissions. This presentation shows measurements in real WiFi scenarios and tells what happens with the message bits on their flight. The presentation also highlights that the implementation of WiFi devices are very different and using a single parameter set to model them is inappropriate and might be misleading.
