What is the function of mobile phone infrared? What s the use. Is it the same as Bluetooth?

It's also a wireless connection function,At present, it has begun to slowly become chicken ribs,Fade out of the market,Its function is the same as Bluetooth,But it's not as powerful as Bluetooth My N73's infrared has been used as a mobile phone remote control hoho

Infrared and Bluetooth have the same function, but the infrared transmission speed is not as good as Bluetooth, and the mobile phone infrared and infrared must be very close to each other in order to transmit normally.

Infrared: Not as fast as Bluetooth transmission, but if the smart phone has infrared, it can be used as a remote control.

One concept is that it is transmitted wirelessly, and the effective distance of Bluetooth is larger.

Trouble, thanks!

It's about the same as Bluetooth, but it's not as easy to pull as Bluetooth.

Mobile phone infrared function function:

1.Mobile phone infrared was first used for point-to-point wireless data transmission, such as two mobile phones with infrared function, through infrared connection can transmit information such as **, documents and so on.

2.The infrared of the mobile phone can realize the function of "universal remote control", and the infrared remote control can be used to control TV, air conditioning and other equipment.

3.Mobile phone infrared is mainly used as screen backlight automatic control. When playing **, the human ear is close to the mobile phone distance sensor, the sensor outputs a signal, and the backlight is turned off, saving unnecessary battery power loss and prolonging the standby time.

Infrared technology is also a wireless communication method that can transmit data wirelessly. Compared with Bluetooth, infrared transmission should not be too far away, it should be aligned in the direction, and there should be no obstacles in the middle. Infrared technology is mainly used for point-to-point linear data transmission over short distances, and the transmission rate is very fast.

vivo mobile phone has an infrared sensor, which senses the distance between the object and the mobile phone after emitting infrared rays and encountering the reflection of the object and receiving it, which is used to trigger a series of functions (such as: the mobile phone will automatically turn off when it is close to the face when it is connected).

If it refers to infrared remote control, the models that currently support infrared remote control function are: iQOO 11 series, iQOO neo7 SE, X90 series, iQOO neo7, X fold+, iQOO 10, iQOO 10 pro, iQOO neo6 SE, x80 series, iQOO neo6, X fold, X note, iQOO 9 Pro, X70 series.

Here's how to check if your phone has an infrared function:

When you hit **, your ears are close to the phone, and the screen will automatically turn black, indicating that there is, otherwise there is none.

PocketPC can exchange information with desktops and other related devices with the help of infrared functions. Mobile phone infrared can control the TV, air conditioner and computer or other mobile phone wireless connection, provided that both parties have infrared.

Principle of connection between infrared devices:

When two infrared devices enter each other's area of action, the device can automatically detect other connections or create connections through user requests, and send connection requests (including address, data rate, and other functional information) to other devices.

The responding device acts as a worker and returns information with address and function. The sender and receiver then change the data rate and connection parameters to the common settings defined by the initial message delivery. Finally, the sender sends data to the receiver to confirm that the connection is successful.

The connected device then starts the data transfer under the control of the master device.

This depends on the specific hardware configuration of each mobile phone, and some mobile phones have it;

Mobile phones that don't have it can also buy an infrared emitter to achieve this function.
