This brand became widely known in 1998, when the leaders of the Bluetooth SIG consortium branded their cost-effective wireless technology for data and sound transmission, an alternative primarily to the popular wired RS-232 standard. Bluetooth power consumption is minimized to 30 mA, and in standby mode it drops below 1 mA, so you can use the wireless transmission and reception channel without fear that the laptop battery will quickly run out. According to the specification, the Bluetooth 5.3 protocol is capable of transmitting data and audio packets at speeds from 64 Kbps in a point-to-point connection up to 2 Mbps in a symmetrical and asymmetric point-to-multipoint connection (with a level of up to 24 Mbps, as at Wi-Fi).

Radio communication is carried out in the ISM frequency range of 2.4-2.5 GHz, with a power of up to 100 mW and up to 100 dBm, with a range of action between devices within a radius of up to 1500 meters.

With Bluetooth, you can not only talk on the phone without hands, listen to music on a home theater speaker system, but also watch a slideshow of photos from your phone on a TV or PC with music, use convenient voice communication in games, Viber, WhatsApp, Skype, other instant messengers and social networks through a secure channel. When we talk about sound transmission, we are talking about connecting a headset, microphone, headphones, playing media content. Bluetooth is a tool for transmitting audio and digital data without the use of cables and wires it is also suitable for creating a small local area network PAN / Wireless networks, Piconet or Scatternet, with encryption algorithms. And there is also a simple, philistine one. There are abstruse scientific answers to the simple question of what Bluetooth is and how it works. What is Bluetooth on PC and other devices Any desktop, laptop, and even portable device running the Windows operating system and having a USB port is able to use all the features of wireless technology if you download Bluetooth for free on a computer for Windows XP, 7, 8.1, 10, 11 (64-bit and 32-bit ). Bluetooth PC Driver for Windows 11, 10, 8.1, 7, XP SP 2 (32-bit and 64-bit) is a universal software required for the operation of a desktop computer, thin client, workstation, server, laptop, netbook, tablet PC with other devices via Bluetooth wireless interface.
