Devices that can uise Wi-Fi technology include personal computers, video-gemme consoles, phones an taiblets, deegital cameras, smairt TVs, deegital audio players an modren prenters. Wi-Fi compatible devices can connect tae the Internet via a WLAN and a wireless access pynt. Sic an access pynt (or hotspot) haes a range o aboot 20 meter (66 feet) indoors an a greater range ootdoors. Hotspot coverage can be as smaw as a single ruim wi waws that block radio waves, or as lairge as mony square kilometres achieved bi uisin multiple owerlappin access pynts.
Wi-Fi maist commonly uises the 2.4 gigahertz (12 cm) UHF an 5.8 gigahertz (5 cm) SHF ISM radio baunds. Onyane within range wi a wireless modem can attempt tae access the network; acause o this, Wi-Fi is mair vulnerable tae attack nor wired networks. Wi-Fi Protected Access is a faimily o technologies creatit tae pertect information muiving athort Wi-Fi networks an includes solutions for personal an enterprise networks. Siccarity featurs o Wi-Fi Protected Access constantly evolve tae include stranger pertections an new siccarity practices as the siccarity laundscape chynges.
