What Is Nfc On Huawei

Near Field Communication (NFC) wireless technology is becoming increasingly popular. Many current models of smartphones and even tablets contain an NFC module. By itself, this technology cannot boast of a high transmission speed, but it can establish a connection in a split second at a distance of up to 10 centimeters. In turn, Bluetooth is not so fast in connection (about 5-10 seconds), but the data on it goes much faster.

Android Beam uses the best of these two technologies and provides instant connectivity combined with high data transfer rates.

Do I have an Android Beam?

Android Beam appeared in the fourth version of the operating system from Google. To make sure your device supports Android Beam, go to Settings. Here under the item “Data Transfer” there is a menu “”.

By going to this menu, you need to view the list for the presence of an NFC item. If such an item is present, then under it most likely there will be an Android Beam option. It’s clear that Android Beam requires that the NFC module is turned on.

We said above that Android Beam uses Bluetooth directly for data transfer, but the user does not need to turn on the Bluetooth module itself before using Android Beam. The smart system does this automatically when connecting via NFC, and immediately after the end of data transfer, Bluetooth is turned off. In combination with the low power consumption of Bluetooth itself, this method of data transfer practically does not affect the battery level of the device.

How to use

So, we have 2 devices with Android Beam and NFC enabled. The data transfer model itself is maximally adapted to the “on the fly” mode. In other words, it is enough for the user to keep the NFC module turned on, and the transfer itself does not require any manipulation in the system interface.

Android Beam allows you to transfer web pages, YouTubes, coordinates and routes in maps, contact data, links to applications on Google Play. photos and many other data.

All the charm lies precisely in the transmission method. No need to click and download anything on the menus. For example, you found cool content in a browser. Without a single tap, bring your device to the device of the person with whom you want to share content, after which a message about the possibility of data transfer will appear on the smartphone screen.

Tap on the screen and that’s it: the recipient will see on your screen the page you submitted in the browser.

Similarly, the transmission of any other data types works. Photos are rummaged right from the gallery, maps. from the maps application and so on.

Subtleties

For Android Beam to work, the screens of both devices must be turned on and unlocked. In addition, if the transfer is from the tablet or to it, then you need to roughly determine where its NFC module is located. In the Nexus 7, it is located in the upper part of the case, and in the Nexus 10, the module will probably be detected near the camera on the rear panel. For smartphones, this is not so important, since the dimensions of the devices allow NFC modules to find each other at any relative position. just bring the devices with the back covers to each other.

Samsung has its own Beam called S Beam. It is important to note that it is not compatible with Android Beam, but Samsung devices also support Android Beam, therefore, when communicating Google-Samsung, you need to use Android Beam, while Samsung-Samsung will understand each other through Android Beam and through S Beam.
