How Wi-Fi Sends Data and Connects Many Devices 📶🌐
Wi-Fi sends data through the air using radio waves, while optical fiber carries data as light through glass cables. Wi-Fi and optical fiber often work together, but Wi-Fi can also receive internet through mobile networks, DSL, cable, satellite, or fixed wireless connections.
A Wi-Fi router can connect many smartphones, laptops, and smart TVs because each device has a unique network identity and usually receives its own local IP address. Internet data is divided into small data packets, which contain information about where the data should go.
The router reads this information and quickly sends each packet to the correct device. Modern Wi-Fi technologies also help routers manage multiple devices more efficiently.
In simple words:
👉 Optical fiber carries data using light. 💡
👉 Wi-Fi carries data using radio waves. 📶
👉 The router identifies each device and delivers its data correctly. 📱🌐
