2. To learn the basic features of overview
Wireshark [https://www.wireshark.org/] is an open source network packet capture and analysis tool used by millions of users worldwide. It is freely available to download for both Windows and MAC platforms, as well as Linux/Unix. Wireshark can be used to capture WiFi packets and inspect the wireless (radio) related aspects of data transmission, such as received signal strength, data rate of the transmission, and so on. This in turn allows us to deepen our understanding of many wireless and mobile data communication protocols and the fundamental theories behind them through hands-on experiments. Figure 1 shows a screen shot of Wireshark displaying some packet capture from WiFi and their radio related information.
Wireshark is a stable software with extensive on-line support, including
• user guide [https://www.wireshark.org/docs/wsug_html_chunked/],
• manual pages [https://www.wireshark.org/docs/wsug_html_chunked/],
• a detailed FAQ [https://www.wireshark.org/faq.html], and
• numerous YouTube videos posted by Wireshark experts and enthusiasts

Your Tasks
1. Download and install the freely available Wireshark in your laptop [https://www.wireshark.org/download.html]. To have full access to Wireshark features, you may need to install it as administrator/root user. Windows users also need to install Microsoft Network Monitor 3.4 [https://www.microsoft.com/en- au/download/details.aspx?id=4865], which is necessary to capture WiFi packets
2. By consulting the on-line manual, user guide, and tutorials, learn some of the important features of Wireshark, such as:
• Capture live packets from the WiFi interface of your laptop
• Display packets with radio-related information, such as received signal strength, data rate,
WiFi beacon interval, etc.
• Save captured packet trace into a file in different formats, such as pcap, and csv (pcap allows
you to import the file into Wireshark for visual inspection, while csv allows you to import the data to tools such as Excel/Matlab/Python for statistical analysis and processing of the data)
• Import previously captured packet traces, captured by Wireshark or other packet dump programs (e.g., Microsoft Network Monitor), from a file into Wireshark
• Filter packets based on some criteria, such as display all WiFi packets transmitted from a particular WiFi access point
• Colorize packet display based on filters
• Create various statistics
• Anything else that you find interesting …
Completing of these tasks will set you up for the next set of labs and the term project, which will make use of wireless packet captures and analysis.
End of Lab 1
