The technology of wireless transmission of data NFC small radius (Near Field Communication) is becoming more popular. Many current models of smartphones and even tablets contain the NFC module. By itself, this technique can not boast high transmission rate, but is able to connect a fraction of a second at a distance of 10 centimeters. In turn, Bluetooth is not as fast in the compound (about 5-10 seconds), but the data on it are much faster.
Android Beam uses the best there is in the two technologies and provides instant compound in combination with a high data rate.
And I have Android Beam?
Android Beam appeared in the fourth version of the Google operating system. To make sure that your device supports Android Beam, go to Settings. Here, under the item "Data Transfer" is a menu "More".
Turning to this menu you want to view the list for any NFC item. If such an item is present, then below it is likely to be checked and Android Beam option. It is clear that it is necessary to NFC module has been enabled for Android Beam.
We mentioned above that for direct transmission Android Beam uses Bluetooth data, but the user does not need to involve itself in Bluetooth before using Android Beam. Smart system does this automatically when connected by the NFC, and at once after the end of the Bluetooth data transfer is disabled. In combination with the low power consumption of the Bluetooth such a method of data transmission has almost no effect on the device battery level.
How to use
So we have 2 devices with Android Beam and enabled NFC. The very model of data as much as possible adapted to the mode of "on the fly". In other words, the user is sufficient to keep the included NFC module and the broadcast does not require any manipulation of the system interface.
Android Beam allows you to transfer, YouTube videos, web pages, location maps and routes, contact information, links to apps on Google Play. photos and many other data.
The beauty lies in the mode of transmission. You do not need to click anything, and ride through the menues. For example, you find cool content in the browser. Without a tapa Bring your device to a person's device to which you want to share content, and then on the smartphone screen will appear on the data transmission capabilities.
Tapan on the screen and everything: the recipient will see on your screen, you transferred your browser.
Similarly operates the transmission of any other type of data. Sharyatsya photos directly from the gallery, maps - maps of applications and so on.
niceties
To work Android Beam requires that the screens of the two devices are turned on and unlocked. In addition, if the transfer goes from the plate or on it, you should give some indication of where his NFC module. At Nexus 7 it is located in the upper housing portion, and at Nexus module 10 surely zadetektitsya near the rear chamber. Smartphone is not so important, because the device size allows NFC modules find each other in any mutual arrangement - just bring your device back covers together.
I have a Samsung Beam called S Beam. It is important to note that it is not compatible with Android Beam, but Samsung devices also support Android Beam, so when communication guglofonov-Samsung need to use Android Beam, while Samsung, Samsung will understand each other and through the Android Beam, and through S Beam.
