In computing, WiFi is a wireless communication technology that connects electronic devices such as computers, tablets, smartphones or cell phones to the internet by transmitting information using radio frequencies or infrared light. WiFi is a wireless communication technology that allows electronic devices such as computers, tablets, smartphones or cell phones, and so on, to be connected to the internet.

It was originally an acronym for the Wireless Fidelity trademark, which in English translates as ‘wireless or wireless fidelity,’ but has since been changed. The use of a hyphen and lowercase letters is recommended when writing WiFi in Spanish. Italics are not recommended in this language. Additionally, it may be used in the same manner as masculine or feminine, depending on desire and context: the WiFi (zone), the WiFi (channel), and the WiFi (channel) (system).

WLAN (WiFi) technology is a computer solution that contains a set of standards for wireless networks that are based on the IEEE 802.11 specifications, which provides compatibility and interoperability in equipment that has been approved under the term WiFi.

Wireless communication, in its purest form, is one that does not rely on cables or other visible physical methods of propagation, but rather on electromagnetic waves to transmit information, which, nevertheless, will be restricted to a set radius of coverage due to the nature of electromagnetic waves.


In order for WiFi to function, it requires a computer (router or router) that is linked to the internet and equipped with an antenna, which then redistributes the signal wirelessly within a certain range. All of the receiving equipment that is inside the coverage area must, at the same time, be outfitted with devices that are compatible with WiFi technology so that they may all have access to the internet. The greater the distance between the equipment and the signal source, the better the connection.

WiFi technology, in the same way, enables the creation of internet connection networks that are beneficial to a large number of people. The availability of free or paid WiFi connections in many public places nowadays is becoming more common. Examples of such locations include: hotels, airports, pubs, restaurants, shopping malls, schools, universities, workplaces, and hospitals, to name a few.
