Wireless standards, protocols, and encryption standards

In this section, we will talk about wireless standards, such as IEEE 802.11, and amendments, also known as wireless bands a/b/g/n/f, and their corresponding frequencies on which wireless or Wi-Fi operate in different countries or zones. So, let's try to understand the various standards of wireless and amendments.

Wireless standards – IEEE 802.11

IEEE stands for Institute of Electrical and Electronics Engineering. Now, the 802.11 standard is split up into two anomalies, named committees and working groups:

• 802 is a committee formed for all network-related norms.
• 11 is a working group specially designed for wireless LAN.

Now, these standards have some amendments built in and are represented as 802.11/b/g/n/ac/ad/a, which are normally in practice.

The following are some of the frequency bands that are commonly used around the globe:
