The technology that connects devices in a personal area network (PAN) is known as Bluetooth. Bluetooth enables short-range wireless communication among devices such as smartphones, tablets, laptops, and accessories like headphones and smartwatches. It is designed for low-power consumption, making it ideal for personal devices. Bluetooth operates within a limited range, typically about 10 meters, allowing for secure data transfer and device connectivity. It is widely used for tasks like file sharing and audio streaming.
