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.
