Bluetooth frequency spectrum

Bluetooth frequency spectrum

  • Device send Low-power signals, the power was only 1 milliwatt, and the technology does not use much
  • Bluetooth signals don’t require line of sight between devices, the radio waves will travel through walls easily, and their Low Power reduces the chance of interference from other technology.
  • Bluetooth has spread-spectrum frequency hopping allows a device to transmit on any one of 79. different, randomly-chosen frequencies While also changing frequencies up to 1600 times per second
