Through this communication protocol, the wireless transmission of information between devices that are within a short distance from each other, usually less than ten meters, is possible.

What Are the Advantages and Disadvantages of Bluetooth Adapters?

Without a doubt, the main advantage of Bluetooth adapters lies in the possibility of being able to connect devices without cables. Besides, they are straightforward to install, and their price is quite low.

On the other hand, since their dimensions are so small, they can be easily lost. Besides, connections via Bluetooth may be affected by interference.

  2. They are straightforward to install

Is It Worth Buying a Bluetooth Adapter?

If your device does not have a connection via Bluetooth, the purchase of an adapter allows you to have a new possibility of wireless connection so that you can connect it to multiple devices.

In this way, it is possible to give new life to older devices. Furthermore, its price is quite low, and it is straightforward to install.

The point is that, as we have seen, with the connections via Bluetooth, the advantages are numerous. Nowadays, the association of devices through this technology is practically indispensable. The future will be wireless, and the new versions of Bluetooth bring us closer to that future.

How Does a Bluetooth Adapter Work?

Communication between two or more devices via Bluetooth is done via radiofrequency. First of all, once Bluetooth is activated, the device detects within its range the other accessories on which it is enabled.

The next step is to connect the devices. Finally, once connected, they will be able to share information.

Can Devices with Different Bluetooth Versions Be Connected with The Bluetooth Adapter?

Yes, not only is it possible to connect Bluetooth devices with different versions, but it is also what occurs in most cases. In general, the best will be that the issuing device was of a higher type and, therefore, more powerful, but it is not important.

This is one of the significant advantages of this technology: its total compatibility between different versions.

Purchase Criteria

Now is the time to buy a Bluetooth adapter, there are a number of purchase criteria to consider. To help you in the selection process, we have selected what we consider fundamental. We hope they serve as a guide in your purchase to choose a device that fully meets your expectations.

  • Use you will make of the adapter
  • Compatibility
  • Bluetooth version
  • Class
  • Range of action
  • Transfer rate

Use You Will Make of The Adapter

Logically, the first thing to consider before buying a Bluetooth adapter is what you need it for. If you want to connect headphones to your computer or various console controllers, you will need different types of devices. Or, you might want to use it with your car radio.

Compatibility

Also, you have to think about whether you plan to use the adapter on a Windows, Linux, or Mac OS device. And, of course, if it is compatible with the version of the operating system you have installed.

And again, it is possible that it is plug and plays with the latest releases, but that requires the installation of drivers for the older versions.

Bluetooth Version

There are several versions of Bluetooth: the most recent is version 5.1 of January 2019. However, the latter version is not yet widespread. Since they are meant to be backward compatible, you don’t have to worry if two devices have different versions.

Obviously, the newer the Bluetooth version, the faster the transfer speed and the better the performance it will offer. Among the different advantages of a more advanced version are lower energy observation and more excellent reliability or safety against interference.

Range of Action

As we have seen, the range of the Bluetooth adapters connection will mainly depend on the type to which it belongs. Usually, devices with a variety of 10 meters are found. An advantage of this type of connection is that it can be created between one room and another, even if there is a wall in the middle.

Transfer Rate

Presently, most of the Bluetooth adapters you will find on the market use version 4.0 or higher. This ensures speeds of up to 32 Mb / s (megabits per second), more than enough, for example, to listen to music or connect a mouse. You will only have to worry about this criterion if you have to transfer large files.

Conclusions

The advantages of wireless connections are indisputable. In the particular case of Bluetooth, they are particularly evident if we want to connect earphones, mice, keyboards, mobile, tablets or console controllers.

However, some older computers do not have this type of connection, so you need to resort to Bluetooth adapters.

These devices are small in size, and their price is decidedly low. Besides, they usually are straightforward to install and configure. Hence their great popularity.

When choosing the adapter, you must take into account the use you will make of it, the version of Bluetooth, and the class to which it belongs. Its following two factors will depend on its range and its transfer rate.
