In this article, we will talk about the Bluetooth adapter. Did you know that Bluetooth technology was initially developed for the Swedish company Ericsson in 1994?

His name is a tribute to an ancient king of Denmark and Norway, Harald Bland, who in English translates as Harold Bluetooth. Given its significant advantages that allow you to connect devices without the need for cables, its use has spread rapidly.

However, many older devices do not have this type of connection. To solve this problem, you can use a practical adapter to be connected to the computer via a USB port. These small devices are very comfortable and straightforward to use. Also, their price is quite low. Here we will be listing the top 7 best Bluetooth adapters.

Things to Consider Before Buying Best Bose Bluetooth Adapters

Thanks to the Bluetooth adapters, you can connect a series of devices to your PC without the need for cables: speakers, earphones, console controllers, mice, keyboards, and even virtual reality devices.

In general, the connection via Bluetooth has a maximum range of 10 meters, allowing the transmission of information between devices located in different rooms.

The various versions of Bluetooth currently in existence are compatible with each other. Usually, a higher version is recommended for the issuing device, but it is not essential.

Bluetooth adapter version 4.0, perfectly compatible with versions 3.0, 2.1, and 2.0. Supports Bluetooth Low Energy (BLE) technology to reduce energy consumption. Compatible with Windows 8, 7 and XP, it allows wireless communication with various types of devices (cell phones, printers, controllers, keyboards …).

Asus is once again a reliable brand: according to buyers, installation is quick and straightforward (however, it may be necessary to download updated drivers from the manufacturer’s website), and the adapter works stably, with excellent reception even in the case of devices separated by a wall.

Maxesla Bluetooth Adapter

Bluetooth adapter was compatible only with Windows computers (10, 7, 8, Vista, XP). It uses advanced 4.0 BLE technology and guarantees a transmission distance of up to 20 meters, with speeds of up to 3 Mb / s. Compact, as big as an inch, very comfortable to take with you on the road or in the office.

Customers highly recommend it for its excellent value for money and ease of installation (plug and play). It quickly detects available devices, connects, and presents no problem in data transmission. Despite its small size, it guarantees a robust and compact structure.

What Exactly Are Bluetooth Adapters?

Bluetooth adapters are small electronic devices that connect to a USB port and allow the connection of devices via Bluetooth wireless technology. 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.

Is It Worth Buying a Bluetooth Adapter?

If your device does not have a Bluetooth connection, 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 elementary 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.

Compatibility

Also, it would help if you thought 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.

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.

The newer the Bluetooth version, the faster the transfer speed and the better its performance. Among the various advantages of a more original version are lower energy consumption and higher reliability or protection against interference.

Class

At the moment, there are four types of Bluetooth signals or classes. Each one is tied to speed and a maximum connection distance. In this way, depending on the level to which the adapter you buy belongs, its performance will be different. You can consult some of the characteristics of each class in the following table.

It indicates, for each class, the maximum power in milliwatts (mW), in decibel-milliwatts (dBm), and the range of action expressed in meters (m). Level 4 is that of the Bluetooth 1.0 version, which has now practically disappeared.

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, or console controllers. However, some older computers do not have this type of connection, so you need to use Bluetooth adapters.

These devices are small in size, and their price is low. Furthermore, 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 Bluetooth version, and the class to which it belongs. Its following two factors will depend on its range and its transfer speed.
