Join Mike Meyers for an in-depth discussion in this video Wi-Fi standards, part of CompTIA A+ Exam Prep (220-901) Part 5: Networking.
- It's hard to believe that the first 802.11 standard…came out way back in 1997.…Since then, 802.11 has pretty much taken over the universe…as our primary wireless technology…that we use for our wireless networks.…Now you could imagine, over time,…we've had a number of standards…that improve on the 802.11 standard,…and that's what this episode is all about.…We're going to go through all of the 802.11 standards…that you're going to be seeing on the A+,…and let's start with 802.11b.…
802.11b was, arguably,…the first big, popular 802.11 standard.…802.11b ran at the 2.4 gigahertz ISM band,…and it ran, which at those days,…was a whopping 11 megabits per second.…It's got a lot faster.…I like 802.11b because it was the introduction…of these famous little routers that began to be seen…all over the place by a little company called Linksys.…The famous black and blue routers…that slowly took over the entire world.…
Now, 802.11b wasn't the only standard that came out…at about the same time.…The other one I want to talk about is 802.11a.…
