Frequency-hopping spread spectrum

Frequency-hopping spread spectrum is like playing hide-and-seek with a radio signal. Imagine you and your friends are playing hide-and-seek outside. Instead of standing in one place and shouting "ready or not, here I come!" you and your friends are hopping from one hiding spot to another without making any noise. Similarly, in frequency-hopping spread spectrum communication, the signal is hopping from one frequency to another, without making anyone notice. This makes it difficult for anyone who might be snooping on the signal to tune in and intercept the message. It's like a secret code that only the sender and the receiver know. And just like you and your friends, they also have to hop to the right frequency at the right time to communicate with each other. This technique is used in many wireless communication systems, like Bluetooth and Wi-Fi, to keep our conversations private and secure.
