A WLAN (Wireless Local Area Network) is specifically defined as a network that uses radio frequency (RF) technologies , primarily Wi-Fi, to provide wireless connectivity. While technologies like infrared, Bluetooth, and ZigBee are wireless communication methods, they are not part of the WLAN definition.
Wi-Fi : Operates in the 2.4 GHz and 5 GHz frequency bands and is the primary technology used in WLANs.
Infrared : Uses light waves for short-range communication and is not part of WLAN standards.
Bluetooth : Designed for short-range personal area networks (PANs), not LANs.
ZigBee : Used for low-power, low-data-rate IoT applications, not WLANs.
Thus, the statement is FALSE , as WLANs are exclusively based on RF technologies like Wi-Fi.
