Bluetooth infrared
Bluetooth and infrared are two different wireless communication technologies that serve different purposes.
Bluetooth is a wireless technology that allows devices to communicate with each other over short distances using radio waves. It is commonly used to connect devices such as smartphones, headphones, speakers, and smartwatches. Bluetooth operates in the 2.4 GHz frequency band and has a range of up to about 30 feet (10 meters) depending on the version of Bluetooth and the surrounding environment.
Infrared, on the other hand, is a wireless technology that uses light waves to transmit data between devices. It is commonly used in remote controls for TVs and other electronics. Infrared requires a direct line of sight between the transmitter and receiver and has a range of only a few feet. It also operates at a much lower frequency than Bluetooth.
In summary, Bluetooth and infrared are both wireless communication technologies, but they are used for different purposes and operate at different frequencies and ranges.
