Bluetooth technology uses a chip that replaces the need for wires and cables. It uses short-range radio frequencies to transmit voice and data information between Bluetooth-enabled devices, like computers, printers, mobile phones, etc. For example, you can use a keyboard or mouse without connecting it to your computer, or talk into your headset without plugging it into your mobile phone.
Bluetooth technology operates at alternating radio frequencies that change 1600 times per second. While other devices, like cordless phones and garage door openers, also use radio frequencies to communicate, it’s very unlikely that Bluetooth would interfere with them.
