The first Wi-Fi standards included 802.11a and 802.11b, but eventually 802.11g, 802.11n, and 802.11ac came out as well. 802.11ax is the most recent standard that has been developed, however (GeeksforGeeks, 2021). The standard that should be used depends on what band the standard will be used on and what speed will be needed. 2.4GHz bands can usually reach farther than 5GHz bands, but they are a bit slower (GeeksforGeeks, 2021). However, it is helpful that some of the standards can operate on both bands (GeeksforGeeks, 2021).
There are also a few Wi-Fi encryption standards. First, there is Wired Equivalent Privacy (WEP), which was the original standard and used the RC4 encryption cipher. However, this standard had many problems, so Wi-Fi Protected Access (WPA) was created and used the 802.11i standard. Finally, Wi-Fi Protected Access 2 (WPA2) was the version based on the final 802.11i standard, and it uses the Advanced Encryption Standard (AES) cipher.
