	===Introduction===		==Introduction==
	Wi-Fi standards define the protocols for wireless communication and are an essential part of modern networking. These standards ensure devices can connect to networks and communicate over wireless channels. Over the years, numerous Wi-Fi standards have been introduced, each improving upon the previous in terms of speed, efficiency, and range. Below is an overview of these standards, including their frequency bands, speeds, modulation schemes, range estimates, and typical use cases.

	===802.11a===		==802.11a==
	The 802.11a standard was ratified in 1999 and operates on the 5 GHz frequency band. It provides a maximum theoretical speed of 54 Mbps, which is relatively low compared to modern standards but was considered fast for its time. The maximum indoor range is approximately 35 meters. This standard uses Orthogonal Frequency Division Multiplexing (OFDM) modulation and is typically used in business environments where the 5 GHz band helps avoid interference from other devices that use the 2.4 GHz band.

	===802.11b===		==802.11b==
	Introduced alongside 802.11a, the 802.11b standard uses the 2.4 GHz frequency band. It provides a maximum speed of 11 Mbps, which was a significant improvement over earlier technologies. It has a much longer outdoor range than 802.11a, with distances reaching up to 150 meters. However, its speed is considerably slower. Direct Sequence Spread Spectrum (DSSS) is used for modulation, which is highly resistant to interference but also limits speed.

	===802.11g===		==802.11g==
	The 802.11g standard operates on the 2.4 GHz band, similar to 802.11b, but it boosts speeds to 54 Mbps using OFDM modulation. The outdoor range is typically around 100 meters. The increased speed made 802.11g a common standard for home networks during the early 2000s. However, the 2.4 GHz band can suffer from interference from other devices like Bluetooth and microwaves.

	===802.11n===		==802.11n==
	Introduced in 2009, 802.11n supports both 2.4 GHz and 5 GHz bands, offering a maximum theoretical speed of 600 Mbps. It supports MIMO (Multiple Input, Multiple Output) technology, allowing for multiple streams of data to be transmitted simultaneously, which helps improve speed and range. The standard's range can extend up to 250 meters in open areas. It was a significant upgrade over 802.11g, allowing for much faster speeds and more reliable connections.

	===802.11ac (Wi-Fi 5)===		==802.11ac (Wi-Fi 5)==
	The 802.11ac standard operates exclusively on the 5 GHz band and supports speeds up to 1.3 Gbps under optimal conditions. This standard introduced several key features, including improved MIMO, beamforming, and wider channels (up to 160 MHz). The outdoor range is approximately 100 meters, and it is well-suited for high-density environments such as public hotspots and large businesses. 802.11ac is commonly found in modern routers and devices.

	Wi-Fi 6, or 802.11ax, was introduced in 2019 and operates on both the 2.4 GHz and 5 GHz bands, with some devices supporting the 6 GHz band as well (Wi-Fi 6E). It significantly improves speed, efficiency, and range, offering a maximum theoretical speed of 9.6 Gbps. This standard introduces Orthogonal Frequency Division Multiple Access (OFDMA) for better bandwidth allocation, Multi-User MIMO (MU-MIMO), and 1024-QAM for improved data density. It is designed for high-capacity environments, such as large offices and homes with many connected devices.

	The latest in the Wi-Fi family, Wi-Fi 7 (802.11be), is expected to offer speeds up to 30 Gbps, though this is still an estimate as the final specification is still in development. It will use the 2.4 GHz, 5 GHz, and 6 GHz bands, further improving bandwidth and reducing latency. Wi-Fi 7 introduces 4096-QAM, allowing for even more data to be transmitted over the same frequency, and extends support for even wider channels (up to 320 MHz). It is designed for ultra-fast, low-latency use cases such as augmented reality (AR), virtual reality (VR), and high-performance gaming.
