What is frequency hopping primarily used for?

Frequency hopping is primarily used to resist jamming and interception. This technique involves rapidly switching the carrier frequency among many different frequency channels, which helps to create a more secure and reliable communication link. By frequently changing frequencies, it becomes much more challenging for an adversary to effectively jam or intercept the communication. Even if one frequency is disrupted or jammed, the transmission quickly hops to another frequency, allowing for continued communication and reducing the risk of the signal being detected or targeted.

The use of frequency hopping is particularly critical in military communications, where maintaining secure communication is essential for operational success and safety. This method increases the resilience of the communication system against various types of electronic warfare tactics aimed at disrupting or spying on the communication signal.
