The technology that allows for short-range wireless communication between devices is Bluetooth. This protocol enables data exchange between devices like smartphones, headsets, and fitness trackers within a limited range, typically up to 100 meters. Bluetooth technology is commonly used for hands-free calling, audio streaming, and file transfers. Its low power consumption makes it suitable for battery-operated devices. With advancements like Bluetooth 5.0, it offers faster data transfer rates and increased connection ranges, further enhancing user experience.
