The wireless or Wi-Fi is a trademark of the Wi-Fi Alliance company which is an organization that certifies and owns the standard 802.11 wireless LANs. Wifi is used to connect different computers to the network wirelessly. This connection is compatible with almost all the equipment that has a receiver of wireless waves of Wifi.
Wifi works in the following way, a central matrix has a cable or equipment that provides the internet, it has an extra accessory (Access Points) with which it distributes the signal wirelessly to a specific radio, this signal, this signal is received by a computer (routers) that gives connection to the equipment that has it connected. The field of compatibility with these networks varies according to the quality and frequency of the antenna. The closer to the field that the antenna covers, the better the connection the device receives.
Today, Wi-Fi certified standards are very popular all over the world. 75% of mobile devices include a Wi-Fi network receiver (laptops, cell phones, Smartphone and USB mobile internet devices). These wireless connections, despite the improvements in service, have had interference with radio frequencies, which causes serious problems in the radioelectric spectrum. Work has been done on the performance of the service since the project began, there are still people who fear it because they consider it unsafe, hundreds of applications have been violated of their security rights (hacked) because the Wifi does not strictly comply with the security guidelines of the Internet.
