Frequency Hopping Spread Spectrum technology is used in the modern wireless remote control systems in order to get interference-free control. It is generally abbreviated as FHSS and it is a method of transmitting radio signals by switching a carrier among many frequency channels. While doing this, the FHSS enabled device uses pseudo-random sequence which is known to both transmitter as well as the receiver. This pseudo-random sequence is generally utilized as a multiple access method in the frequency-hopping code division multiple access schemes. FHSS technology when used in modern remote control technology can provide a lot of advantages to the operators.
According to the system as well as the device standard the Frequency Hopping Spread Spectrum Technology may provide a lot of advantages. However the basic advantages of the FHSS technology over a fixed-frequency transmission is as follows:
The signal comes from spread-spectrum are highly resistant especially to narrowband interference. The interfering signal is spread out by the spread signal during the process of re-collecting data. This causes it to recede into the background.
One of the main characteristics of spread spectrum signal is that it is difficult to intercept. The FHSS signal simply appears as an increase in the background noise to a narrowband receiver. The transmission can only be intercept by an eavesdropper when the pseudorandom sequence is known.
The main advantage of FHSS technology is that it prevents all types of signal interference. The spread spectrum transmissions can share a frequency band with many types of conventional transmissions that allows minimal interference. Apart from that the FHSS technology also adds minimal noise to the narrow-frequency communications and vice-versa. This helps you to utilize the bandwidth more efficiently.
Due to all these advantages, wireless remote controls in modern days are being designed with FHSS technology. FHSS technology is widely used in radio remote control systems including wireless emergency shutdown system, automated leak detection system, remote controlled driver authorization system, aircraft refueling systems, crane control trucks and many more. Using FHSS technology in these modern remotes has increased job safety and increased productivity.
Actually all of these above mentioned wireless controls are used to control the gigantic industrial machines. Job site safety is really important in the industrial sectors as it reduces the unwanted accidents. Interference is such a thing that can create serious problem in the gigantic machines. However FHSS technology largely lessens the problem. During any kinds of system interference the FHSS system can shut down the whole unit keeping the machine in fail-safe mode. This ensures the safety of the machine as well as the operator.
Frequency Hopping Spread Spectrum Technology when installed in a wireless device can ensure the transference of the signal. The transmission frequencies are determined by a spreading, or hopping code. During this time the receiver should be set to the same hopping code. It must listen to the incoming signal at the right time and correct frequency in order to properly receive the signal.
