Question

FHSS (frequency hopping spread spectrum) is a technique used in some RFID systems to prevent interference. It works by rapidly switching the carrier frequency between different channels, making it more difficult for interference to affect the reliability of the system. ASK (amplitude shift keying), PSK (phase shift keying), and CW (continuous wave) are modulation techniques used in RFID systems but do not specifically address interference prevention.
