They must follow a set of wireless standards or protocols, known as IEEE 802.11, to wirelessly communicate with other devices. The WiFi standards were created by the Institute of Electrical and Electronics Engineers and are certified by the WiFi Alliance. The goal is to create a better wireless LAN experience for the users.
802.11 standards are developed every couple of years to fill holes in the current one and to account for the development of new wireless technology. New standards can be developed to improve speeds, range, security, or establish new frequency bands when applicable.
To fulfill a growing demand for faster internet under the 2.4 GHz band, 802.11g joined the 802.11 family in 2003. The developers took the best qualities of 802.11a and 802.11b to create the 802.11g standard. It supports a networking bandwidth up to 54 Mbps and operates under the 2.4 GHz band.
As of 2019, the 802.11ax standard has become the newest WiFi standard. Designed to deliver faster speeds, support more devices simultaneously, decrease latency, improve security, and increase bandwidth. To do so, it includes technologies like OFDMA, MU-MIMO, 1024-QAM, and more. With all of its improvements, it has a theoretical maximum speed of 10 Gbps.
The WiFi Alliance came up with a new naming system to make it easier for vendors to indicate which standards their devices support, for service providers to explain what their network offers, and for users to understand which products work with each standard.
Rather than using the 2.4 GHz band, it opted into using the 5 GHz frequency band. Generally, higher frequencies are coupled with faster speeds but shorter range.
In 1997 , the first WLAN standard was released - IEEE 802.11. It was developed to operate on the 2.4 GHz ISM band and supported speeds of 1 Mbps - 2 Mbps. Compared to the speeds we have now, it would take longer to download files and cause challenges with group video calls, online gaming, and streaming.

802.11 is a WLAN (Wireless Local Area Network) standard developed by IEEE (Institute of Electrical and Electronics Engineers).
WiFi stands for Wireless Fidelity. WiFi is the marketing name for IEEE standard 802.11. It is a standard for both Level 1 (physical) and Level 2 (data link) of a wireless data transmission protocol.

CSMA (Carrier Sense Multiple Access) is a Media Access Control (MAC) protocol that is used to control the flow of data in a transmission media so that packets do not get lost and data integrity is maintained.
