Bluetoothtehnoloogiat

Bluetoothtehnoloogiat, commonly known as Bluetooth, is a wireless technology standard used for exchanging data between fixed and mobile devices over short distances. It operates using short-wavelength UHF radio waves in the ISM band from 2.4 to 2.485 GHz. Bluetooth allows for the creation of personal area networks (PANs) connecting devices such as mobile phones, headsets, keyboards, and speakers. Its primary purpose is to replace the cumbersome cables that connect electronic devices.

The technology was developed by the Ericsson company in 1994 and was officially standardized by the Bluetooth Special Interest Group (SIG). Bluetooth 1.0 was released in 1999. It has since undergone numerous revisions, with each version offering improvements in speed, range, and power efficiency. Bluetooth 5, released in 2016, significantly enhanced data transfer speeds and increased the range, while also introducing features like lower energy consumption for IoT devices.

Bluetooth technology is widely integrated into a vast array of consumer electronics. Its applications range from simple audio streaming to wireless keyboards and mice, car hands-free systems, fitness trackers, and smart home devices. The ubiquity of Bluetooth has made it a cornerstone of modern wireless connectivity, simplifying the way devices interact and reducing cable clutter in everyday life.
