What's the Difference Between WLAN and Wi-Fi?

Sunday, October 31, 2021

Not all wireless is wi-fi but most of it is the terms wireless LAN or wireless local area network and wi-fi are often used interchangeably but they're not the same and this confusion can lead to problems put simply wi-fi is one type of wireless LAN which is just one type of wireless network just like,


how all squares are rectangles but not all rectangles or squares all wi-fi networks are wireless LANS but wireless LANS can use other wireless protocols a wireless LAN enables devices to connect and communicate wirelessly as opposed to a wired LAN that communicates over cabled ethernet a wireless LAN transmits data over radio frequencies wireless LAN typically have larger coverage than wireless personal area networks but are smaller than wireless wide area networks and wireless metropolitan area networks which are other types of wireless networks.


Wi-fi is a wireless protocol that uses 802.11 standards created by IEEE such as 802.11a 802.11b 802.11g and 802.11n these standards operate in different frequencies and other distinct features making up the different types of wireless LANS wi-fi connects 802.11 enabled access points to 802.11 clients while also providing access to the internet wi-fi networks are the most common type of wireless LAN because they most often serve human clients directly but they can vary in frequency and feature set


Bluetooth also uses radio signals to connect devices and share information between them but it has a shorter range than wi-fi so it's better suited for connecting nearby devices like wireless speakers to smartphones as a result Bluetooth can be used in both wireless LANS and wireless pans Zigbee and z-wave specifications are also used to create wireless pans primarily for smart home devices like programmable light bulbs and security sensors recognizing the differences between wireless LAN and wi-fi is important when attempting to run multiple wireless lans in the same space wireless lands require security considerations and proper design to avoid congestion or overwhelming frequencies.
