The Wi-Fi technology is based on a set of standard specifications defined by the IEEE (Institute of Electrical and Electronics Engineers) 802.11 family. These standards outline the protocols for implementing wireless local area networks (WLANs) and have evolved over time to support faster speeds, increased range, and enhanced security features. Here’s a brief overview of the key Wi-Fi standards:
- 802.11a: Operates in the 5 GHz band, providing speeds up to 54 Mbps.
- 802.11b: Operates in the 2.4 GHz band, offering speeds up to 11 Mbps.
- 802.11g: Operates in the 2.4 GHz band, supporting speeds up to 54 Mbps, compatible with both a and b.
- 802.11n: Introduced MIMO technology, allowing for multiple antennas, with speeds up to 600 Mbps and operates on both 2.4 GHz and 5 GHz bands.
- 802.11ac: Operates primarily in the 5 GHz band, supporting gigabit speeds up to 3.46 Gbps through wider channels and advanced technology.
- 802.11ax (Wi-Fi 6): The latest standard, providing greater efficiency, higher throughput, and improved performance in congested areas, with speeds exceeding 9.6 Gbps.
As Wi-Fi technology continues to advance, these standards play a crucial role in ensuring interoperability between devices and facilitating the growing demand for high-speed internet connectivity.
