Yesterday, we talked about theBluetooth adaptercan make the computer that does not have Bluetooth function have Bluetooth function, smoothly connect Bluetooth headset, mouse, keyboard and other devices. Today Saiyue Technology Editor will share with you how to choose a good Bluetooth adapter.
1. First look at the Bluetooth adapter version
Different versions of the Bluetooth adapter in the transmission rate and coverage or quite a big difference, high version of the Bluetooth adapter also has some advanced technology features. What is the difference between the different versions?
Bluetooth version |
Transmission characteristics |
Bluetooth 1.0 |
The transmission rate is about 748~810kpbs, which will be interfered by the communication of the same frequency products |
Bluetooth 1.2 |
The transmission rate remains unchanged, plus the anti-interference frequency hopping function, and supports single-channel playback |
Bluetooth 2.0 |
The transmission rate is increased to 1.8Mpbs~2.1Mpbs, EDR technology is added, duplex mode is supported, and files are transmitted while supporting voice communication |
Bluetooth 3.0 |
The transmission rate has increased rapidly, reaching 21M/s, using a new alternating radio frequency technology, supporting video transmission, and reducing power consumption |
Bluetooth 4.0 |
The transmission rate is increased to 24M/s, the theoretical transmission distance is up to 100 meters, ultra-low power consumption, password-free pairing (direct connection via NFC) |
Bluetooth 4.2 |
Faster transmission speed, enhanced security, and the ability of the Internet of Things |
Bluetooth 5.0 |
More advanced bluetooth chip, support left and right channels to receive audio independently, stronger data processing capability and lower delay |
Bluetooth 5.1 |
With the addition of direction finding function and centimeter-level positioning service, indoor positioning will become more accurate, and the position of small objects can also be accurately positioned to avoid item loss |
Bluetooth 5.2 |
Added enhanced ATT protocol, LE power control and LE sync channel, etc. |
In summary, it can be seen that the higher the Bluetooth version, the more powerful the experience will be better.
Bluetooth versions all support backward compatibility. For example, your headset is Bluetooth 5.0, and the Bluetooth adapter supports 4.0, then you connect to use the Bluetooth protocol 4.0, not 5.0. so it is recommended to try to buy a high version of the Bluetooth adapter
2. The Bluetooth chip used
Bluetooth adapter with high reliability, good compatibility, low power consumption and other characteristics, Bluetooth adapter core chip selection is also very critical. Choose a reliable chip manufacturer, the quality will also be more secure.
Now on the market many Bluetooth 4.0 chip said to be compatible with 5.0 chip, because Bluetooth 5.0 compatible with 4.0 Bluetooth adapter, the so-called compatible can only say that can be used, but can not play a high version of the function, if you want to buy Bluetooth 5.0 must look at the right chip.
3. Signal coverage and signal strength
The Bluetooth adapter on the market coverage range between 0 ~ 20 meters, the greater the coverage range, the more convenient and unrestricted use, you can meet the freedom to use Bluetooth devices in a larger space needs.
Generally the higher the Bluetooth version, the stronger the signal strength, and the coverage range is naturally larger. Use 5.0 and above specification version of Bluetooth products, from compatibility, energy consumption, transmission rate, cost and other aspects of a comprehensive consideration is a better choice.
4. Use experience
More features and appearance, if there is no good use of the experience is a rogue. Good use experience mainly depends on four points.
*Low latency, no lag, stable signal
*Automatic memory, can be used again automatically pairing
*Compact size, easy to carry around
In general, it is recommended to choose Bluetooth 5.0 or 5.1 version of the Bluetooth adapter, so that if you have other high Bluetooth standard devices can also be compatible, the user experience is also better.
