Bluetooth is a short-range, low-power, wireless cable-elimination technology. It’s designed to connect gadgets in pairings that make sense, like cellphone+earpiece, Mac+wireless keyboard, phone+portable speaker, or Mac+cellphone (for tethering, where you connect the Mac to the phone so the laptop can get online).
