What are the new standards for Bluetooth technology?

Currently the most widely beats solo used Bluetooth 2.0 + EDR standard Bluetooth headset, this standard has been introduced in 2004, from the emergence of this standard, support for Bluetooth 2.0 + EDR standard products in 2006, a large number of emerged. Although the Bluetooth 2.0 + EDR standard has been technically made a lot of improvements, but some problems still exist, such as from the 1.X standard continuation of the configuration of complex processes and equipment, large power consumption. In order to improve the Bluetooth technology currently exists these problems, Bluetooth SIG organization immediately launched a Bluetooth 2.1 + EDR version of the Bluetooth technology headphones. So in the improved version, in the end what are the advantages?

First, have a better power saving effect

Bluetooth 2.1 beats by dre on sale version of the new addition to the Sniff Subrating function, technically by setting the two devices to confirm the transmission interval between the two signals to achieve the purpose of saving power. In general, when there are two Bluetooth devices connected to the standby state, in fact, between the Bluetooth devices still need to call each other to determine whether each other is still online. Of course, it is precisely because of this, the Bluetooth chip must always keep working state, even if the other components of the phone have entered the sleep mode, but the Bluetooth device must remain in the working state. In beats earphones order to improve this situation, the Bluetooth 2.1 device will be the mutual confirmation of the signal transmission interval from the old version of 0.1 seconds extended to the current 0.5 seconds or so, the main words can make the Bluetooth chip workload greatly reduced, you can also let Bluetooth devices have more time to go for a thorough dormancy.

Second, to improve the device matching process

Because there are many Bluetooth headset users in the hardware between the Bluetooth pairing problems encountered, they are in the process of pairing, the operation is too complicated, so there is a need to use personal identification code to ensure the security of the connection, So as to improve the connection. The short distance of the pairing, but also have two Bluetooth-enabled mobile phone hardware between the matching and communication transmission NFC mechanism. What is NFC, NFC is a short-range wireless RFID technology, which is in the 1 to 2 meters for short-range online applications, this is based on electromagnetic waves, to replace the traditional radio transmission method. As the NFC mechanism controls the initial detection of the Bluetooth pairing, so when the two devices within the scope to be paired transmission, as long as the simple click beats by dre cheap on the phone screen is not to accept the online on it.
