Bluetooth - Page 2

Bluetooth is a wireless communication technology that allows devices to exchange data over short distances using radio waves. It primarily enables the connection of various devices, such as smartphones, laptops, headphones, and other peripherals, facilitating the transfer of files, audio streaming, and device control without the need for wired connections. Bluetooth operates in the 2.4 GHz frequency range and employs a technique called frequency-hopping spread spectrum to minimize interference and improve reliability. It supports multiple profiles that define specific use cases, such as wireless audio (A2DP), hands-free communication (HFP), and file transfer (OBEX). The technology is characterized by low power consumption, making it suitable for portable devices. Bluetooth has evolved through various versions, enhancing data transfer speed and range, with the latest iterations supporting advanced features, including mesh networking and improved security.
