Which Huawei phones have infrared rays?

Mobile phones that support infrared functions include: Huawei Mate 40 Pro, Huawei Mate40E, Huawei Mate 40 RS Porsche Design, Huawei Mate 30 Pro 5G, Huawei Mate40, etc.

The so-called infrared ray refers to electromagnetic radiation with a wavelength exceeding red visible light. Mobile phone infrared can control TVs, air conditioners and wireless connections with computers or other mobile phones, provided that both parties have infrared.

Mobile phone infrared technology is most commonly used for data exchange between mobile phones and computers and other digital devices. With infrared technology, these seemingly complex data transmissions become very simple. First we must prepare an infrared adapter. If we want to download files from the computer to the mobile phone, we also need a computer and a mobile phone with infrared capabilities. Select the files you want to transfer on the computer, send them to the designated device, and then align the infrared adapter with the infrared interface of the mobile phone for data transmission.

Disadvantages

But the power consumption of infrared mobile phones is very large, far more than Bluetooth. Turning on for too long affects the life of the infrared and the battery to a great extent. Infrared technology is also a wireless communication method that can transmit wireless data. Compared with Bluetooth, infrared transmission cannot be too far away, must be aligned, and there must be no obstacles in the middle. At present, infrared technology is mainly used for short-distance point-to-point linear data transmission, and the transmission rate is very fast. For example, if you want to send a picture or ringtone to a friend, you only need to send the selected file in infrared mode, and then align the infrared interfaces of the two mobile phones, so that the sending can be successful quickly. Of course, there is no information fee for sending files through infrared, but the two parties must be very close to each other, usually about one meter.
