Whether you’re at home, school, or a café, you rely on Wi-Fi for internet access. But despite the importance of this technology in everyday life, not many people know how it works. If you’re curious about the Wi-Fi system and internet access, below is a comprehensive guide that explains everything you need to know.

How Does Wi-Fi Work?

Wi-Fi systems use radio waves to transmit data. Your computer, laptop, or smartphone come with a built-in wireless adapter that translates data into a radio signal, which is then received by the wireless router using an antenna. The router decodes the data and transmits to the internet using an Ethernet connection. The process also works in reverse to move data from the Internet onto your Wi-Fi-capable device. There are two possible Wi-Fi frequencies, which include 2.4 GHz and 5 GHz, that carry data. 

Is It Safe to Connect to Public Open Networks?

Public Wi-Fi refers to internet access offered in public places, such as cafes, malls, airports, and restaurants. The main risk of connecting to these networks is that you have no way of telling what the level of security is on these channels, and someone can intercept your data as it’s traveling between your device and the router. The best way to prevent this is by using a VPN, or a virtual private network, and to disable file sharing.
