Bluetooth is a short-distance wireless communication technology, that allows electronic devices such as mobile phones, computers, and peripherals to transmit data.
- Bluetooth uses less power than Wi-Fi. Its lower power also makes it far less prone to suffering from or causing interference with other wireless devices in the same 2.4GHz radio band.
- Due to less power consumption of Bluetooth (up to 2.5 milliwatts), it has a short range of up to 10 metres (33 ft).
- Bluetooth uses UHF radio waves in the ISM bands, from 2.402 GHz to 2.48 GHz to transmit data.
Bluetooth is mainly used as an alternative to wire connections, used in mouse, keyboards, smartwatches, headphones, music players, mobile phones and computers etc.
