[[wikipedia:Wi-Fi|Wi-Fi]] [[wikipedia:wireless|wireless]] [[wikipedia:Computer networking|networks]] provide all the functionality of wired networks, without the need for physical connections. Data is sent over various [[wikipedia:radio frequency|radio frequencies]] depending on the service. Typical Wi-Fi connection speeds are 11 and 54 [[wikipedia:Megabit per second|Mbps]]. In practice, throughput is about half the connection speed. Wireless Networks basically consists of computers equipped with wireless [[wikipedia:Network card|NICs]], which may be [[wikipedia:Universal Serial Bus|USB]], [[wikipedia:Peripheral Component Interconnect|PCI]], [[wikipedia:Mini PCI|Mini PCI]], [[wikipedia:Compact flash|CF]] card, [[wikipedia:PC card|PCMCIA/CardBus]], or other interface. Connectivity to a wired network requires a wireless ''access point'' (AP) used as a [[wikipedia:Bridging (networking)|bridging]] device. Connectivity to the Internet usually requires a ''wireless router'', which includes an access point. AP's are typically located near the centre of the wireless client concentration. | [[wikipedia:Wi-Fi|Wi-Fi]] [[wikipedia:wireless|wireless]] [[wikipedia:Computer networking|networks]] provide all the functionality of wired networks, without the need for physical connections.
