What's the difference between Samsung S Beam and Android Beam | Love Computer - 上海419贵族宝贝-上海后花园1314-上海品茶网-阿拉爱上海

Some time ago, I accompanied my friends to buy mobile phones. The salesperson in the store sold us a Samsung mobile phone, Said, "This mobile phone has the S Beam function. As long as you touch someone else's mobile phone, you can send the video to the other person's mobile phone through Bluetooth, and the speed can reach 300MB/sec..." I laughed when I heard this, and pulled my friend to go quickly. If you listen to me again, a digital idiot like my friend will surely be fooled. It's better to buy an Apple, and less trouble, and more importantly, less trouble.

The transmission speed is 300MB/s. The hard disk of your sister's desktop is not so fast. It depends on the people and the level of deception. The theoretical maximum speed of Bluetooth 4.0 is 24Mbps, that is, 3MB/s. Where did you get 300MB/s. Although the salesperson is quite deceitful, at least the technology of S Beam is a very good function. Let's introduce it below.

S Beam is a function that combines NFC and wifi to realize data transmission. As long as two S Beam enabled mobile phones are back-to-back, and you touch them on the screen, you can easily share business cards, maps, photos, videos, music, etc. Does this sound like what we introduced in the previous article Android Beam Yes, Android Beam and S Beam are very similar in usage and function. But in fact, they are based on different technologies.

Android Beams are paired via NFC and then transmitted via Bluetooth. S Beams are paired via NFC and finally transmitted via WiFi. WiFi is definitely faster than Bluetooth. In the actual test, 1GB movie files can be transferred to each other within three minutes, or 10MB music files can be transferred within two seconds. If the Android Beam transmits a 1GB video, it is estimated that it will wait until dawn.

Although the technology of S Beam is much better than that of Android Beam, S Beam is the exclusive technology of Samsung, which means that only Samsung phones that support this technology can use it, so the limitation of this function is quite large.
