Introductory Seminars for First-Year Students
The Wireless World, and the Data You Leak
The world is increasingly based on wireless communication. Cell phones and WiFi are the most visible examples. Others are key fobs, water meters, gas and electric meters, garage door openers, and baby monitors. The list will continue to rapidly expand with the realization of the Internet of Things. All of these devices produce radio frequency (RF) signals you can detect and often decode. In this seminar we will explore how much information you broadcast throughout your day, and how it can easily be received and decoded using inexpensive hardware and public domain software. You will be able to explain why different information services use different frequencies, why they encode the information the way they do, and what security risks they present.
The requirements for this course are a personal computer and some familiarity with installing public domain software. We will supply an RF receiver that works with MacOS, Windows, or Linux.
The course website, EE26n.stanford.edu, has much more information about what we will do in our seminar.
