Meaning of wifi (what is it, concept and definition)

What is Wifi:

Wifi is a wireless communication technology that allows electronic equipment, such as computers, tablets, smartphones or cell phones, etc., to be connected to the internet, using radio frequencies or infrared for the transmission of information.

Wifi or Wi-Fi is originally an abbreviation of the Wireless Fidelity trademark, which in English means 'wireless or wireless fidelity'. In Spanish, it is advisable to write wifi without a script, in lowercase and without italics. In addition, it can be used in the same way in masculine or feminine, depending on preference and context: the wifi (zone), the wifi (system).

In this sense, Wi-Fi technology is a computing solution that includes a set of standards for wireless networks based on IEEE 802.11 specifications, which ensures compatibility and interoperability in equipment certified under this name.

The wireless communication, as such, is one that ignores cables or physical means visible propagation, and that, by contrast, uses electromagnetic waves for transmission, being this, however, it is limited to a specific radio coverage.

For its operation, the wifi needs a computer (router or router ) connected to the internet and equipped with an antenna, so that in turn it redistributes this signal wirelessly within a certain radius. The receiving equipment that is within the coverage area, at the same time, must be equipped with devices compatible with Wi-Fi technology so that they can have internet access. The closer the equipment is to the signal source, the better the connection.

In this sense, Wi - Fi technology allows the implementation of internet connection networks that benefit multiple users. Today, many public places, such as hotels, airports, bars, restaurants, shopping malls, schools, universities, offices and hospitals, are equipped with hotspots that offer free or paid Wi-Fi connection.
