'''WiFi''' is a form of wireless [[internet]] access. WiFi is different from [[cellular]] internet access in that it is delivered via ''hotspots'' and is usually limited  to specific areas, like [[hotels]], [[hospitals]], [[restaurants]], [[airports]], [[airplanes]], [[ships]], [[libraries]], [[schools]] and [[universities]], [[stores]], [[shopping malls]], and [[apartment|apartment complexes]], but in some regions like Sunnyvale in [[Silicon Valley]], WiFi may cover entire [[cities]]. To access WiFi, one must have a device capable of accessing the signal, 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 users. WiFi can be achieved 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.
