Wireless Standards

Welcome to the Cybrary IT A+ Certification course for the CompTIA Exam, in today’s lesson we are going to explore the different stands and encryption types for Wireless Communications.

We begin by examining what wireless communications are, which is basically connecting to a network through a router using radio frequencies over the air instead of directly through physical hardware.  We’ll look at how that process has changed over the years in terms of range, speeds, and technologies.

For example, we have wireless interface cards which may or may not be pre-installed.  We have different authentication methods, and all follow the 802.11 standard which defines the frequencies, configuration, speeds, encryption keys and distance.

There are four (4) 802.11 Standard types and we’ll diagram and explain each.
