Evolution of WLAN technology improves data rates, security

By Michaela Goss

Over the past 20 years, wireless LANs, or WLANs, have evolved in tandem with the internet: at a rapid, widespread pace with no sign of slowing down.

Data rates, modulation and security are among the most significant changes in the evolution of WLANs. In particular, Wi-Fi -- a form of WLAN technology -- is in its sixth generation, Wi-Fi 6, which also promises more innovations in network speeds and security. However, WLAN fundamentals are still crucial to know, according to author Alan Bensky. In the third edition of his book Short-range Wireless Communication, Bensky explores the fundamentals of WLANs and other wireless communication technologies.

Below is an excerpt from the book: Chapter 11, "Wireless local area networks." This chapter lays out everything readers need to know about WLANs, including WLAN architecture, physical layer details and location services. Bensky also notes how the evolution of WLAN technology has progressed since the advent of wireless communications.

Noteworthy changes for WLANs include the following:
