Probably everyone is familiar with this situation - you listen to music, work or just relax at your PC. Here, slightly forgetting that you are wearing headphones, you get up, and as a result, the keyboard, mouse, mug of tea fall off the table, and the cord is pulled out or simply breaks. After this, you will think about purchasing a Bluetooth adapter for your computer, so that you can later buy and connect wireless headphones.
A USB or PCI Bluetooth adapter allows you to transfer information from one device to another at a speed of 3-10 Mbit/s. Often in the hustle and bustle of everyday life, you need to connect your phone, smartphone or tablet to your computer in order to upload photos, videos or other files. As a rule, not everyone has a cord to connect a device, and the wires often get lost or fail, breaking at the wrong moment.
How it works
If earlier it was easy to find support for Bluetooth technology in laptops, then over the last 5 years “blue tooth” has been extremely rare. More often than not, wireless technology is present and standard in mobile phones.
The USB Bluetooth adapter for a computer or laptop looks like a small flash drive that is connected by connecting to a USB port. Some developers and companies install antennas on models that increase the coverage area.
Yes, now you can transfer information packets from one room to another, or wear wireless headphones to the toilet, kitchen or balcony. It’s really not worth washing in them if there is no waterproof technology, and there are no such headphones yet, but perhaps they will appear soon.
True, the board itself is installed inside the computer. The plastic chip has a standard appearance with a PCI connector for connecting to the motherboard. This is even more convenient, since it frees up the USB port. Users also often connect an external adapter to the front panel, where it sticks out like a flagpole. And then they knock it out with their foot or hip, breaking the port, which, you see, is not very pleasant.
This technology will not only allow you to connect wireless devices such as headphones or a printer, but also quickly exchange information between PCs, laptops, and phones.
What is it for?
If you still don’t understand what a Bluetooth adapter is needed for, I’ll give you the main opportunities that it opens up for the user:
- Transfer files from PC to smartphone or tablet and back. Almost all mobile phones are equipped with a BT transmitter;
- Wireless connection of two computers located close to each other;
- Connecting to a PC a wireless keyboard, mouse and other equipment that supports this communication protocol. It is especially convenient to use wireless headphones when you can’t make noise in your apartment or want to talk on Skype without sitting at the monitor.
The advantages of using an adapter include:
- Low energy consumption of radio communications. Having the device turned on will not greatly affect the computer's power consumption or the rate at which the laptop's battery drains.
- The connection remains stable even if there are obstacles between devices:
- It can be connected to any PC that has a USB version 2.0 or 3.0 port;
- Low cost of expanding functionality. Sometimes, it is more profitable to buy a computer without a built-in chip and buy an additional USB module than to spend money on a more advanced package;
- Availability in the vast majority of smartphones and tablets.
pros
- Quickly download photos, videos, documents from your phone to your PC.
- Huge selection of devices in terms of power and price.
- Installation on any modern computer.
- Possibility of connecting wireless devices: mice, keyboards, joysticks, headphones, printers, MFPs.
- Walk around the apartment wearing headphones with a microphone and talking on Skype.
- Connecting old phones if the cable is lost.
- Connecting phones, tablets.
- Transfer data between two computers or laptops.
Is it possible to make a wireless module yourself?
Sometimes the question is asked: is it possible to make a transmitter with your own hands? This option is quite difficult to implement. You cannot assemble a microcircuit with your own hands at home, since it is very miniature, requires very delicate work, and the selection of the frequency range is carried out using integrated solutions; the protocol has been developed by specialists for years.

Therefore, radio amateurs can only use ready-made Bluetooth transmitters and modify them at their own discretion, adding the necessary elements to the finished circuit with their own hands. Some suggest upgrading a music speaker with a module or making wireless speakers, as well as adding a transmitter to the car’s audio system to avoid a clutter of wires and download your favorite music directly from the Internet.
The video below shows in detail how to do this. But in any case, such manual work requires good knowledge and skills in radio engineering, otherwise from one working Bluetooth module and additional elements you can get a set of disparate radio components.
Good day!
If every modern laptop and smartphone already has a built-in Bluetooth adapter, then with a PC the situation is exactly the opposite - only a few motherboards are equipped with a built-in module...
This, in turn, makes it problematic to connect various wireless devices to the PC: joysticks, headphones, speakers, etc. Many users, by the way, encounter this after purchasing a gamepad...
