Bluetooth and Wi-Fi are both wireless technologies but serve different purposes. Bluetooth is primarily designed for short-range connectivity between devices, typically within a range of about 30 feet. It's optimized for low power consumption, making it ideal for devices like headphones, smartwatches, and fitness trackers. In contrast, Wi-Fi is used for higher-speed internet access and can connect devices over greater distances, from a few dozen feet to several hundred. Wi-Fi bandwidth allows for data-intensive activities like streaming and gaming, whereas Bluetooth is better suited for audio transmission and peripheral connections.
