Range for using the infrared wireless port when updating
This means you can place boxes out of the way (or even sometimes hidden in an AV closet) and still control everything like they were out in the open.To communicate with a cable box, an IR blaster must align to the same infrared frequency.Since this device is pumping out a stronger signal than your TV or cable box, you can sit at a comfortable distance away from your electronics and still change the channel, plus the signal will go through certain walls. IR blasters are also found with devices like the Slingbox M2, which use them to control your TV from anywhere you have an internet connection.This is how you're able to change the channel while streaming your live TV from anywhere. Though it's less common these days, phones like the Samsung Galaxy S6, S6 Edge, LG G5, and others included IR blasters on the tops of phones.These are most commonly used for short-range or medium-range communications between two devices.
Bluetooth is a wireless technology standard that uses short-wavelength UHF radio waves (2.4 GHz to 2.485 GHz) to transmit and receive data over short distances (typically within the range of 10 meters).This is especially true if you have a remote that works via Wi-Fi and hardware that relies on infrared communication.In these situations, you'll often find a little piece of gear called an IR blaster.Notably, the Samsung S7 series of phones dropped the IR blaster feature, which may hint at dark times ahead for the fate of technology.Wikipedia has a partial list of devices with IR blasters, but that's looking pretty anemic.
