'''WiFi''' is a form of [[wireless]] [[internet]] access (Wireless Local Area Network). WiFi is different from [[cellular]] internet access in that it is delivered via ''hotspots'' and is limited  to specific areas, like [[hotels]], [[hospitals]], [[restaurants]], [[airports]], [[airplanes]], [[ships]], [[libraries]], [[schools]] and [[universities]], [[stores]], [[shopping malls]], and [[apartment|apartment complexes]]. To access WiFi, one must have a device capable of reviving and sending the signals, like a [[laptop]], [[mobile phone]], or [[Video game|portable gaming device]]. [[DSL]] and [[cable modem]] connections are typically used to provide internet connectivity to WiFi acces points, which in turn provide Internet access to wireless users. WiFi can also be provided in a residential setting using a wireless router or internet gateway device. Wi-fi was invented by the [[Australia]]n government's research arm, the CSIRO.<br />

In some places such as Sunnyvale in [[Silicon Valley]], WiFi is largely replaced by [[WiMAX]], which can service entire [[cities]].
