The technology that allows for the wireless transmission of data over short distances using radio frequency is Bluetooth. Bluetooth enables devices like smartphones, computers, and peripherals to communicate without the need for cables, facilitating easy data transfer and connectivity. It is widely used for pairing devices such as headphones, speakers, and smartwatches. By using low-power radio waves, Bluetooth provides a convenient and energy-efficient solution for short-range communications, making it integral to modern smart technology and the Internet of Things (IoT).
