frequency hopped spread spectrum code

详 情 说 明

Frequency-hopped spread spectrum (FHSS) code is a type of wireless communication that is used to improve the security and reliability of data transmission. It works by transmitting data over multiple frequencies in a random pattern, making it difficult for unauthorized users to intercept and decode the signal.

FHSS codes are commonly used in military and government communication systems, as well as in other applications that require a high level of security and reliability, such as medical devices and financial transactions. Additionally, FHSS codes are often used in conjunction with other types of wireless communication technologies, such as Bluetooth and Wi-Fi, to provide an extra layer of security.

In terms of its history, FHSS technology was first developed in the 1940s by actress Hedy Lamarr and composer George Antheil, who were looking for a way to secure radio-controlled torpedoes against enemy jamming during World War II. While their invention was not widely adopted at the time, it laid the foundation for modern FHSS technology and its widespread use in the digital age.
