mupe - MUltiPath Estimator

This script was originally written to evaluate RSSI signal strength jitter for 802.11 based wireless lan networks. The script expects tcpdump/tshark PCAP files w/ Radiotap headers.

The processing is based on timeslots (default 2sec). The following data is processed:

• beacon frames

  • MAC clock difference charts the clock difference between the AP STA and the sniffing STA

  • losses: charts lost frames per timeslot

  • signal distribution: charts RSSI distribution of the hole capture

  • signal jitter: charts MAX-MIN RSSI per timeslot

  • signal trend: charts MIN/AVG/MAX RSSI per timeslot

• data frames

  • signal distribution: charts RSSI distribution of the hole capture

  • signal jitter: charts MAX-MIN RSSI per timeslot

  • signal trend: charts MIN/AVG/MAX RSSI per timeslot
