Wireless Network Technologies - CompTIA A+ 220-1201 - 2.2

When we hear the term wireless technologies, most of us probably think about the wireless networks that we use at home or at our business to be able to connect to other devices on the network or to the internet. This type of network is one that is standardized by the ILE E. This is the Institute of Electrical

and Electronics Engineers. And the committee that handles the standards for this type of network is the 802.11 committee. That's why you'll often hear these networks referred to as 802.11 networks. However, the 802.11 committee realizes that using the 802.11 name along with a series of letters to designate what version of the network it

happens to be might be confusing for some. So, in order to make this a bit easier to follow, they've changed the naming convention so that the 802.11 AC standard is also called WFI 5. They then referred to the 802.11 AX standard as Wi-Fi 6 and Wi-Fi 6E for extended. And the 802.11BE standard is also called Wi-Fi

7. This makes it a bit easier to differentiate between versions. So instead of using those 802.11 names, you can simply use Wi-Fi 5, Wi-Fi 6, Wi-Fi 7, and so on. Our Wi-Fi networks have a number of different frequencies that they might use to be able to facilitate this communication. And different standards of Wi-Fi use different

frequencies. Most Wi-Fi networks will use frequencies in the 2.4 GHz range, the 5 GHz range, and the 6 GHz range. And some access points and devices can communicate across multiple ranges simultaneously. Instead of having to memorize or reference a specific frequency, the 802.11 committee has grouped frequencies together into channels. These channels are much easier
