Frequency hopping is a mechanism that is used to reduce interference in wireless communication systems. It works by rapidly changing (or hopping) the frequency of the signal used for communication between two or more devices. The frequency that each device uses is predetermined based on an agreed–upon sequence of frequencies. This technique helps to spread out the transmitted signal power over the available range of frequencies, thus making it difficult for any single receiver to detect the transmission. Frequency hopping can also be used in other types of radio transmissions, such as those used in Bluetooth and Wi–Fi networks.
Frequency hopping is a technique used in wireless communication systems to reduce interference and improve security by rapidly switching the frequency of the signal. It works by transmitting data over multiple frequencies in a random pattern, which makes it more difficult for an unauthorized user to intercept the signal. Frequency hopping is used in a variety of wireless communication technologies, including Bluetooth, Wi-Fi, and radio frequency identification (RFID).
