With the continuous development of technology, people's lives have become more and more convenient. For example, when we are at home, we can turn off the lights without having to press the switch. This is a particularly happy thing for lazy people. This is mainly due to RF controller, which is one of our most widely used household tools. Then, how much do you know about it?

What is RF?

 

RF is the abbreviation of Radio Frequency, which is a kind of high-frequency alternating electromagnetic wave. It is a communication technology that can identify specific targets and read and write related data through radio signals without requiring mechanical or optical contact between the recognition system and specific targets.

 

RF optimization is the optimization of radio frequency signals. Its purpose is to optimize network coverage while ensuring good reception quality. At the same time, the network has the correct neighbor relationship, so as to ensure that the distribution of wireless signals is normal during the next step of business optimization, in order to lay a good foundation for work.

 

What is the working principle of RF?

 

The basic working process of the system is: the reader sends a radio frequency signal of a certain frequency through the transmitting antenna. When the radio frequency card enters the working area of the transmitting antenna, an induced current is generated, and the radio frequency card obtains energy and is activated.

 

The radiofrequency card transmits its own encoding and other information through the built-in transmitting antenna of the card; the system receiving antenna receives the carrier signal sent from the radio frequency card, and transmits it to the reader through the antenna adjuster. The reader demodulates and decodes the received signal and then sends it to the background main system for related processing.

 

The main system judges the legitimacy of the card according to the logic operation, makes corresponding processing and control for different settings, and sends out instruction signals to control the action of the actuator.

 

What can RF controllers be used for?

 

Radio frequency (RF) remote controls are very common. Garage door openers, car alarms, and radio-controlled toys have always used radio remote controls, and this technology has also begun to appear in other applications. They are still rare in home theater equipment, but you will find RF remote controls controlling certain satellite TV receivers and high-end stereo systems. You can also find Bluetooth-based remote controls that control laptops and smartphones.

 

Instead of sending light signals, the radio frequency remote control sends radio waves corresponding to the binary commands of the buttons you press. The radio receiver on the controlled device receives the signal and decodes it. The problem with RF remote controls is that there are a lot of radio signals flying around in the air at any given time. Cell phones, walkie-talkies, WiFi settings, and cordless phones all transmit radio signals at different frequencies. The RF remote control solves the interference problem by transmitting at a specific radio frequency and embedding a digital address code in the radio signal. This lets the radio receiver on the target device know when to respond to the signal and when to ignore it.
