Bluetooth and infrared
Bluetooth and Infrared are two different technologies used for wireless communication.
Bluetooth is a wireless technology that allows devices to communicate with each other over short distances. It is commonly used for wireless audio streaming, hands-free calling, and file sharing between devices such as smartphones, laptops, and headphones. Bluetooth technology uses radio waves to transmit data between devices.
Infrared, on the other hand, uses light waves to transmit data between devices. It is an older technology compared to Bluetooth and is often used for remote controls for TVs and other home appliances. Infrared signals cannot penetrate walls and have a limited range of only a few meters.
Both Bluetooth and Infrared have their own advantages and disadvantages. Bluetooth has a longer range, can penetrate walls, and supports higher data transfer rates compared to Infrared. Infrared, on the other hand, is less susceptible to interference and is more secure as it cannot be intercepted by devices outside its range.
I hope this gives you a basic understanding of the difference between Bluetooth and Infrared. If you have any more questions, please feel free to ask.
