In today's smart TVs or other smart home appliances, we often see two kinds of remote control work methods, one is the more common infrared, the other is relatively rare in the past, but has also rapidly spread in the past two years Bluetooth. Maybe a lot of friends don't understand why they are remote controls. Can they be separated by remote control technology? Or is it better than which? Xiao Bian today briefly introduced these two mainstream transmission technologies.
The first thing to say is Bluetooth. Bluetooth is a short-range wireless data transmission. It is also a wireless data transmission method that is often used in the mobile phone field. The transmission rate of this transmission mode was generally low before, and it was ideal after 4.0. It was also relatively large in power consumption, but the strong transmission angle was 360 degrees and was not affected by the direction.
Infrared is the more commonly used transmission method for remote control of home appliances. It supports devices for data exchange. Infrared communication has the characteristics of low cost, convenient connection, simple and easy to use, and compact structure, so it has been widely used in small mobile devices. Through the infrared interface, all types of mobile devices can freely exchange data.
Infrared is an electromagnetic wave having a wavelength between 750 nm and 1 mm. Its frequency is higher than that of microwave but lower than visible light, and it is a kind of light that human eyes cannot see. Due to the short wavelength of infrared light, the diffraction ability of obstacles is poor, so it is more suitable for applications where short-range wireless communication is required, and point-to-point linear data transmission is performed, and the transmission rate can reach 16 Mbps at the fastest. The Infrared Data Association (IRDA) limits the wavelength of light waves used in infrared data communications to within 850 nm to 900 nm.
Infrared and Bluetooth are currently used as wireless data transmission protocols. How do they differ in the application of technology? Or what are the advantages and disadvantages of these two technologies? Here we go through this table to understand the difference between them ~
I believe that after reading this picture, everyone can understand the difference. Infrared is the most ideal transmission method for the household electrical appliance industry for a long period of time. Its advantages are naturally testable, but at the same time as the quality of life of people is improved, The defects are also becoming increasingly prominent. It can be said that infrared technology is a technology that may be eliminated in the near future. As Bluetooth technology advances with the times, the disadvantages of its original amplification are gradually compensated, coupled with its unique advantages, it will surely become the mainstream transmission method in the future.
