Frequency Hopping is a method used in wireless communication where the signal rapidly changes its frequency among a set of predetermined channels. This technique helps to minimize interference and improve security, making it harder for unauthorized listeners to intercept the communication. Originally developed for military applications, Frequency Hopping is now widely used in technologies like Bluetooth and Wi-Fi. By constantly shifting frequencies, devices can maintain a stable connection even in crowded environments, ensuring better performance and reliability in data transmission.
