What is an IR blaster, and how does it work?


An infrared blaster (IR sounds better and less techy) is a gadget that accepts some sort of input from your remote and "blasts" it via infrared to the IR-compatible device you're trying to control. One common example is with some smart remotes, like the Logitech Harmony Elite.

This remote doesn't have to communicate directly with your device. Instead, the remote talks with the Harmony Hub. You can attach mini IR blasters to the hub and these blasters can then send your commands to devices like your cable box, stereo receiver, or Blu-ray player.
The main reason you'd something like this is you don't have to have line-of-sight with the device you're controlling; only the IR blasters and the hub they're attached to have to be near your boxes. 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.

How it works with a cable box

To communicate with a cable box, an IR blaster must align to the same infrared frequency. Luckily, this is done automatically during the setup process of capable smart TVs. You will be asked for your zip code and what cable service provider you use, and sometimes the make and model of your cable box. After answering these brain-busters, your TV will adjust to the proper frequency, and ask you to change the channel to make sure the blaster is working.

Are there any other benefits to using an IR Blaster?

We’ve reviewed some TVs that have terrible IR sensors on them: Pressing a button on the remote will not do anything unless it is pointed directly at the sensor. There are no (appropriate) words for this kind of frustration.
This brings us to an additional benefit of using an IR blaster: It can extend the range of your remote, and it can overcome obstacles. 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. Cable box blocked by a stack of Blu-rays? Not a problem.

What devices are compatible with an IR blasters


IR blasters are also found with phones like the "Coolpad Cool 1", which use them to control your TV,AC,Set top box and other remote controllers gadgets from respective distance from gadget. You also have to be connected with internet connection. This is how you're able to change the channel  while streaming your live TV from anywhere.
You will also find IR blasters on some other phones. 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.

I really appreciate the capability of cool1 dual and Le2 to work as smart remote. These phones can learn from any IR remote... This feature is absent in any other company phone like Xiaomi and Lenovo. Appreciate LeEco/coolpad for it and wish they don't skip this in next mobiles... Moderators please convey appreciation to R&D team and send them feedback to not to skip this in future versions...

What I mean is LeEco devices and coolpad cool1 dual have IR sensor in addition to IR emitter. You can bring any random IR remote control in front of LeEco phone/cool1 dual and it learns from it and so you can make any custom remote control of your choice.  

This is not available in Redmi 4A. Xiaomi devices can only work with templates. It cannot learn from any random remote control. The reason is that they don't have IR sensor. Only IR emitter in Xiaomi devices.

Please learn from here how it works:
