Wifi is a wireless communication technology which allows electronic equipment, such as computers, tablets, smartphones or cell phones, etc., to be connected to the Internet, through the use of radio frequencies or infrared for the transmission of information.
Wifi either Wifi It is originally an abbreviation of the trademark Wireless Fidelity, which in English means ‘wireless or wireless fidelity’. In Spanish, it is advisable to write wifi without a hyphen, in lowercase and without italics. In addition, it can be used equally in masculine or feminine, depending on preference and context: the WiFi (zone), the WiFi (system).
In this sense, the wifi technology is a computer solution that includes a set of standards for wireless networks based on the IEEE 802.11 specifications, which ensures compatibility and interoperability in equipment certified under this name.
The wireless communicationas such, is one that dispenses with cables or visible physical means of propagation, and that, on the contrary, uses electromagnetic waves for its transmission, which, however, will be limited to a specific coverage radius.
For your functioningWi-Fi requires equipment (router or router) connected to the Internet and equipped with an antenna, so that it in turn 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 access to the Internet. The closer the devices are to the signal source, the better the connection will be.
In this sense, the technology Wifi allows to implement internet connection networks that benefit multiple users. Nowadays, many public places, such as hotels, airports, bars, restaurants, shopping centers, schools, universities, offices and hospitals, are equipped with hotspots that offer paid or free Wi-Fi connection.
