The technology that allows devices to communicate wireslessly over short distances is Bluetooth. It enables data transfer between devices like smartphones, tablets, and computers within a limited range, typically up to 100 meters. Bluetooth creates a secure connection, simplifying tasks such as file sharing or syncing audio with wireless headphones. This technology is widely used in wearable devices, smart home products, and other consumer electronics. Its ability to connect multiple devices simultaneously facilitates convenience and improves user experiences across a variety of applications.
