2, for some details, such as NFC function, let's answer it. First of all, Mi Mix 3 does have NFC function, which is the legacy of Xiaomi's flagship seriesIn general, MIX3 as the latest masterpiece, naturally will not be absent. You can find confirmation in the detailed parameters of Mi Mix 3, check the description below the wireless network section, as shown in the picture. For whether you can brush the bus with NFC, the answer is yes.
3, Xiaomi 9:released at the end of February 2019, equipped with Snapdragon 855 processor, support 20W wireless charging, water drop screen appearance, priced at 2999 yuan, equipped with NFC and infrared. Mi Mix 3: Released at the end of October 2018, slide design full screen, pretty appearance, equipped with Snapdragon 845, support NFC infrared, officialThe quotation is 3299 yuan. Millet MIX 2S: Released at the end of March 2018, put now configuration is also good.
4, Mi Mix 3 not only wireless charging, but also support wired charging. It is understood that the previous generation of millet mix2s wireless charging power is only 5W, and this means that the wireless charging power of mix3 is more than 5W, to achieve fast charging, if this is the case, the practicality of wireless charging function is bound to be further improved.
Mobile phone infrared can be wirelessly connected to a computer or other mobile phone, provided that both parties have infrared. When using the mobile phone, the infrared function should be enabled. Close to the infrared port of the computer, the computer automatically searches for signals, and if successful, the sign of infrared connection will appear on the system tray. You can then upload the data to your phone (in the format it supports).
With the higher and higher configuration of the mobile phone, there are too many modules that need to be placed on the forehead, such as speakers, cameras, light distance sensors, etc., so it is reasonable to remove the infrared function that has almost no use value, if you increase the infrared connectionMouth, the top of the fuselage also needs to open a hole, which has an impact on the sealing of the whole machine, especially the appearance, so it can only remove the unimportant original.The Mi 8 can not control the TV, because the Mi 8 has no infrared remote control function. In order to increase the internal space of the Mi 8 screen, the design can save the principle of saving, so there is no infrared emission hole, and there is no headphone hole. As a high-end flagship millet 8 is not equipped with infrared remote control, the main reason is confirmed by Lei Jun: "Millet 8 forehead plug too many things, it can not put down."
Mi 8 has no infrared remote control function, so you can't control the air conditioner. Xiaomi in order to layout the smart home ecological chain, from high-end flagship to low-end red rice series are all equipped with infrared functions. But this time as a high-end flagship millet 8 is not equipped with infrared remote control, the main reason was confirmed by Lei Jun: "Millet 8 forehead plug too many things, it can not put down."
This phone does not, now Android phones with infrared is very few, there was no WIFI transmission before, so it is more convenient to use infrared, now there is WIFI and Bluetooth 0, so most mobile phones are not equipped with infrared function.
Hello, Honor 20 this phone is 128G or 256G versionBen doesn't have an infrared remote control. The Honor 20 PRO, an enhanced version of the Honor 20, also doesn't support infrared remote control. Glory V20, another model in the Honor Math series, supports infrared remote control. If there is a need and you like the Honor brand, you can consider it. Honor V20 relative to Honor 20, both use Tianma hole screen, the same Kirin 980 processor.
Current Wireless charging infrared , the commonly used wireless access technology mainly includes infrared port technology, Bluetooth technology and 8011 wireless LAN technology. radio interface technologies (RIT) Wireless access technology (also known as air interface) is a key issue in wireless communication. It refers to the connection between the user terminal and the network node through the wireless medium wireless charging infrared to achieve the transmission of information between the user and the network.
At present, the commonly used wireless access technology is mainly infrared port technology Bluetooth technologyAnd 8011 LAN technology. Physical layer characteristics. 8011 technology uses radio waves to communicate at the physical layer. It supports different frequency bands wireless charging infrared , including 4GHz and 5GHz. The specific frequency band can vary from version to version of the standard.
At present, the commonly used wireless access technology mainly includes infrared port technology, Bluetooth technology and 8011 LAN technology. Infrared port technology Wireless charging infrared : data transmission through infrared, suitable for short distance communication, such as remoteTransmission of control signal between controller and TV. Bluetooth technology: The use of 4GHz band for short-distance data transmission, suitable for mobile phones, headphones, mice and other devices connection.
The most widely used short-range wireless communication technologies are Bluetooth, wireless LAN 8011 (Wi-Fi) and infrared data transmission (IrDA). At the same time, there are some promising near-field wireless technology standards, they are: Zigbee, Ultra WideBand (Ultra WideBand), Short range communication (NFC), WiMedia, GPS, DECT, Wireless 1394 and dedicated wireless systems.
Infrared data transmission belongs to wireless network access technology. According to the query of relevant information, infrared communication technology uses infrared to transmit data, is a kind of wireless communication technology, infrared communication technology does not require physical connection, simple to use and low cost to achieve, so it is widely used in small mobile devices to exchange data and control electrical equipment, such as laptop computers, personal digital assistants, mobile phones and so on.
The following four aspects from the transmission mode, network topology, network interface and support for mobile computing are describedThe characteristics of wireless local area network are described. Transmission mode The transmission mode involves the transmission media, selected frequency band and modulation mode used by the wireless LAN. At present, there are two main transmission media used in wireless LAN, namely microwave and infrared.
