Bluetoothsignaalid

Bluetoothsignaalid are radio waves used for short-range wireless communication between devices. These signals operate in the 2.4 GHz ISM (Industrial, Scientific, and Medical) band, a frequency range that is largely unregulated and widely available for unlicensed use. The technology relies on a master-slave architecture where one device, the master, initiates and controls the communication, while other devices, the slaves, respond to its requests.

When two Bluetooth devices want to connect, they perform a process called pairing. This involves a discovery phase where devices can detect each other, followed by authentication to ensure they are connecting to the intended device. Once paired, they can establish a connection, often referred to as a piconet, which can consist of one master and up to seven active slaves. Bluetooth signals are designed to be robust against interference from other devices operating in the same frequency band through techniques like frequency hopping, where the signal rapidly switches between different frequencies within the allocated band. This allows multiple Bluetooth devices to coexist and communicate effectively in close proximity. The range of Bluetooth signals is typically around 10 meters, though this can vary depending on the device class and environmental factors.
