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 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 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 Australian government's research arm, the CSIRO.
