Wireless local area network, often referred to as Wi-Fi, is a technology that allows devices to connect and exchange information over the internet without relying on cables. Data is transmitted through radio waves between different devices and an access point (typically a router). This technology allows for people to move around freely and conveniently in their own homes, offices or any other public place while being online. Wireless LANs can support various devices like laptops, smartphones, intelligent home gadgets and Internet of Things (IoT) devices among many others. Usually, wireless network support is required to ensure optimal performance, security, and for debugging of connectivity issues during the establishment and maintenance of a wireless local area network (WLAN). The reason for this support is to fully realise the advantages of wireless networking in an increasingly connected world.
