The wireless technology that we use today can trace its origin to radiotelegraphy, which transmitted information using electromagnetic waves. Wireless communication today travel over the same electromagnetic waves including radio frequencies, infrared, cellular, and satellite. The Federal Communications Commission (FCC) regulates how the wireless spectrum is used in the United States to ensure stability and reliability. It is up to the users to protect their data at rest as well as their data in transit.

802.11

The Institute of Electrical and Electronics Engineers Standards Association (IEEE) is an organization that develops standards for wireless communication gathering information from subject‐matter experts (SME). IEEE is not an institution formed by a specific government but is a community of recognized leaders who follow the principle of “one country, one vote.”

The IEEE 802.11 is a set of specifications on implementing wireless over several frequencies. As technology has evolved, so has the need for more revisions. If you were to go shopping for wireless equipment, you would see the array of choices you have based on those revisions of 802.11. Most consumer and enterprise wireless devices conform to 802.11a, 802.11b/g/n, and 802.11ac standards. These standards are better known as Wi‐Fi. Bluetooth and wireless personal area networks (WPANs) ...
