Since its inception in 1971, the Wi-Fi technology since then has evolved a lot. Wi-Fi technology provides high-speed internet access to devices within a specific range of the wireless network. The Internet has made it possible to stay connected with everyone around the globe at any given point in time. Wi-Fi is a type of radio waves which has many advantages over traditional cables, primarily it can access spaces where cables cannot reach. But how does this popular wireless technology work?
Technology behind Wi-Fi –
Wi-Fi is the technology that uses radio waves to provide internet access to other devices. These radio waves are transmitted over the network using a Wi-Fi router. All the devices like laptops, smartphones, tablets, etc. have in-built Wi-Fi cards. These Wi-Fi cards receive the radio waves from the router. The range of the Wi-Fi depends on the router. Now along with Wi-Fi at home, there are Wi-Fi hotspots set up at public places like restaurants, schools, colleges, hotels, etc.
Benefits of Wi-Fi over traditional cable wires –
- Flexibility – Any user on the network is free to move within the range of the wireless network. While in case of traditional wires the user’s mobility is restricted
- Infrastructure – Setting up a wireless network is cost-effective as compared to the traditional network. A lot of money is spent on labour and installation in wired networks.
- Reachability – The wireless network can be extended to the places where the cables cannot reach.
- Scalability – If you want to add any user on the network it can be effortlessly done in a wireless network. However, in a wired network, you will need to add new cable wires
