The former aim of Wi-Fi networks was to provide mutual wireless connection of portable devices and their connection to (e.g. office) LAN networks. However, the strong potential of this technology has started to be used for connection to the internet. The initially slow spreading of the Wi-Fi technology was rapidly accelerated by its integration into the mobile platform Centrino by Intel. Not only thanks to it Wi-Fi has become a standard part of portable computers. It has spread mainly due to using the non-license band which has negative effects in strong interference within that frequency spectrum and common security incidents.
A partially evolutionary result and successor of Wi-Fi is the currently-constructed wireless technology called WiMAX which should provide wireless access to the internet within large areas in the city.
