Question

We use or cell phone for several features, for that we need to be connected to the internet. Have you ever stopped to think, how does the internet, fiber optics and WI-FI work? Discrete or spectrum of WI-FI radiation and optical fiber, and how do they work?

Answer 1

Fiber optics use low loss, high bandwidth optical fibers for long-distance data transmission, while Wi-Fi provides wireless connectivity using microwaves in the 2.4 to 5 GHz range.

Step-by-step explanation:

The internet and connected devices like cell phones and laptops communicate using electromagnetic waves. One of the key technologies for this communication is fiber optics, which uses optical fibers to transmit data. Optical fibers use total internal reflection to guide light through glass or plastic cables, which can extend across the ocean floor or be buried underground. Because of their low loss, high bandwidth, and reduced crosstalk properties, they are superior to copper wires for long-distance communication.

Moreover, Wi-Fi uses microwaves within the 2.4 GHz to 5.0 GHz spectrum to enable wireless internet access. Wi-Fi routers modulate and demodulate these microwaves to communicate with devices, following specific standards for compatibility. These microwaves can pass through common building materials, which makes them suitable for indoor wireless connectivity.
