#Infrared Bluetooth difference

Infrared (IR) and Bluetooth wireless technologies are commonly used for short-range wireless communication between electronic devices. Bluetooth remotes work the same way as Infrared remotes, but instead of sending light pulses, they send the codes to the device via radio waves. Furthermore, unlike Infrared, Bluetooth also allows transmission even through walls and other objects, and there is no need to point the remote to the device, as it does not require to be in the line of sight. Connectivity In terms of operation, a Bluetooth-enabled device can connect with multiple devices at a given time, while Infrared usually connects on a one-to-one basis. However, since Infrared handles a one-to-one connection, the chance of interference in data transmission from other connected devices is lower than the chance that Bluetooth might experience. However, Bluetooth remotes take an advantage over Infrared in effective range, and it doesn't need line-of-sight to function, providing more flexibility and convenience. In this guide, we’ll walk you through some simple steps to add essential features to your PC —- including Wi-Fi, Bluetooth, NFC, and Infrared. Turn on WiFi and try to connect to a network, pair your computer with a Bluetooth speaker, test NFC connectivity with a compatible device, and use the Infrared to remotely control your PC.
