Wi-Fi is a technology that allows devices to connect to the internet without physical cables
Institute of Electrical and Electronics Engineers (IEEE)
IEEE is responsible for setting the standards for Wi-Fi networks
802.11 Specifications
802.11 specifications dictate how wireless networks operate
Wi-Fi standards have evolved over time to accommodate the increasing demand for faster and more reliable wireless communication
802.11a operates on the 5 GHz band with a maximum speed of 54 Mbps
802.11b operates on the 2.4 GHz band with a maximum speed of 11 Mbps and offers compatibility with older devices
802.11g provides speeds up to 54 Mbps on the 2.4 GHz band
802.11n introduced MIMO technology, enhancing both speed and range
802.11ac increased data transfer rates and is capable of achieving speeds up to 9.6 Gbps
802.11ax further increased data transfer rates and is the latest Wi-Fi standard
Wi-Fi standards ensure that devices from different manufacturers can communicate effectively and specify the radio frequencies and channels to reduce signal interference
Wired Equivalent Privacy (WEP)
WEP was the original security protocol but was found to have significant security flaws
Wi-Fi Protected Access (WPA)
WPA superseded WEP and employs the robust Advanced Encryption Standard (AES)
WPA3
WPA3 offers even stronger security features, such as individualized data encryption and protection against brute-force attacks
Wi-Fi performance is affected by factors such as the Wi-Fi standard used, proximity to the access point, environmental interference, and network congestion
To maximize Wi-Fi performance, it is advisable to use the latest Wi-Fi standards, reduce interference, optimize router placement, manage the number of connected devices, and use strong security protocols
2.4 GHz Band
The 2.4 GHz band provides extensive coverage but is more susceptible to interference and offers lower data throughput
5 GHz Band
The 5 GHz band supports higher data rates and is less prone to interference but has a reduced range
