That’s why some equipment now uses RF remotes. [Xtropie] used a pair of inexpensive 433 MHz RF modules to convert an IR system to RF. You can see a short video about the project below.

And, using a few off-the-shelf parts [hesam.moshiri] shows us how to take advantage of this piece of spectrum by designing and building a programmable and versatile 4-channel 433 MHz remote control.

Arduino 433 MHz Receiver/Transmitter Arduino project for receiving and (in the future) transmitting signals using a 433 MHz RF module. Currently, this repository contains code for a 433 MHz signal ...

Use your Arduino or Raspberry Pi to operate remote radio controlled devices. This will most likely work with all popular low cost power outlet sockets. If yours doesn't work, you might need to adjust ...

Pi enthusiasts that have built a Raspberry Pi media centre may be interested in a new OSMC RF Remote Control that has arrived at the Adafruit online store ...
