Taajuusvaihteluita
Taajuusvaihteluita, also known as frequency hopping, is a technique used in wireless communication systems to improve the security and reliability of data transmission. In frequency hopping, the transmitter and receiver change frequencies according to a predetermined pattern, known as a hopping sequence. This technique helps to minimize interference from other signals and reduces the likelihood of eavesdropping, as an attacker would need to follow the hopping pattern to intercept the communication.
Frequency hopping can be implemented in various ways, including fast frequency hopping (FFH) and slow frequency
Frequency hopping is widely used in military and secure communication systems, as well as in some commercial
