Line 6:
A '''wireless network interface controller''' ('''WNIC''') is a [[network interface controller]] which connects to a [[wireless network]], such as [[Wi-Fi]] or [[Bluetooth]], rather than a wired network, such as a [[Token Ring]] or [[Ethernet]]. A WNIC, just like other NICs, works on the layers 1 and 2 of the [[OSI model]] and uses an [[antenna (radio)|antenna]] to communicate via [[radio wave]]s.
A wireless network interface controller may be implemented as an [[expansion card]] and connected using [[Peripheral Component Interconnect|PCI]] bus or [[PCIe]] bus
The low cost and ubiquity of the [[Wi-Fi]] standard means that many newer mobile computers have a wireless network interface built into the [[motherboard]].
