The presence of Bluetooth (Eng. Blue tooth) in modern devices has long been considered the norm. Almost all mobile devices are equipped with such modules. Why do we need it, this Bluetooth is a question that any first grader can easily answer today. A stationary PC, unlike laptops, netbooks and tablets, is equipped with “blue-tooth technology” optionally. The absence of this option is not a reason to shed bitter tears over the pet's system unit. It is possible, using the Bluetooth adapter, in a few minutes to make available all the amenities that this technology provides to its users.
How is this possible? This will be discussed in our review. But first, a little history. Bluetooth technology is a way to transfer information, manage devices, connect multiple devices to a local network, etc. All this can be done without using a wired connection. Back in 2000, several companies for the first time announced devices with this technology on board. At that time, it was just fantastic: transferring files without the help of wires was beyond comprehension.
A little over ten years have passed and bluetooth, as a technology for wireless data transmission, has become a familiar phenomenon. Headsets, headphones, keyboards, mice, printers, cameras, laptops - all these (and not only these) devices can now work and “communicate” with each other without the help of wires. Despite the fairly solid age of the technology, it is still in high demand and popular with manufacturers and consumers. The undoubted advantages of the “blue tooth” include stability, the minimal impact of interference on the operation of devices, as well as the low cost of such equipment.
If the computer or laptop is suddenly not equipped with a Bluetooth module, this defect can easily fix the Bluetooth adapter. And you need very little money for this. On average, for $ 5-10 you can buy a Bluetooth adapter that connects to a PC via a USB port. The miniature size of some models allows you to use them as portable devices, they are almost invisible and do not cause any inconvenience. When there is a need to use Bluetooth - with a light movement we insert the adapter into the USB port and ... everything, complete freedom from eternally tangled wires.
What is required for installation? Minimum set:
- USB Bluetooth adapter ;
- Device driver and software for work (included);
- Free USB port on computer / laptop.
The installation procedure is simple. The Bluetooth adapter is inserted into the USB port, and the installation disk is inserted into the drive. Run the installer. We agree with all the proposals, we still continue the installation, even if suddenly "... the equipment was not tested ...". After the installation is complete, you need to check that the Bluetooth adapter is in the list of devices.
Now you can easily connect various devices to your PC, transfer and receive files, use a communicator or mobile phone modem to access the Internet, which is very important in the absence of alternative options for accessing the Internet.
Among the competitors in the wireless market, two trends can be noted: the gradual departure from the scene of infrared communications (IrDa) and the steadily growing popularity of the IEEE 802.11 standard (aka Wi-Fi).
The transmission of information through the infrared port loses its relevance - devices should only be in the line of sight, the transmission speed leaves much to be desired. Manufacturers almost stopped installing infrared ports in their devices. We can say that it was successfully replaced by Bluetooth.
Which is better, Bluetooth or Wi-Fi - the question is not worth it. These two wireless standards have been living peacefully in a “civil marriage” for many years, sharing responsibilities. Wi-Fi is a local area network and Internet connection, Bluetooth is data transfer, Hands free, connection with a computer of various peripheral devices , etc. From this symbiosis, buyers have one sheer benefit - most devices with this sweet couple “on board” provide the maximum degree of freedom. By the way, you can install both a Bluetooth adapter and a Wi-Fi module on your PC yourself. But this is a completely different song ...
