The technology that enables wireless communication between devices over short distances is known as Bluetooth. This protocol allows devices, such as smartphones, tablets, and laptops, to connect and exchange data without the need for physical connections or cables. Bluetooth technology operates in the 2.4 GHz radio frequency band and supports a range of applications, including audio streaming, file sharing, and smart device control. Its low power consumption and ease of use make it ideal for personal area networks (PANs), facilitating seamless connectivity between users and their devices in everyday settings.
