Bluetooth: Connecting Devices with Short-Range Wireless Technology
Bluetooth is a short-range wireless technology standard used for exchanging data between fixed and mobile devices over short distances. It operates on the 2.4 GHz radio frequency band, allowing for the creation of personal area networks (PANs) for a wide range of applications. Originally designed as a wireless alternative to RS-232 data cables, Bluetooth has evolved into a ubiquitous technology for connecting everything from headphones and keyboards to smart home devices and medical sensors. Its key benefits include low power consumption, affordability, and the ability to operate without line-of-sight, making it an essential component of the modern connected world.
