Answer 1

${ \huge{ \tt{ \color{red}{answer}}}}$

If you currently have a TV, stereo system, or any sort of remote control, then you likely have either an infrared or radio frequency remote. ... RF remotes use specific radio frequencies, typically a license-free 2.4 GHz bandwidth, to transmit a signal to a receiving device.

All IR remotes use the infrared frequency range (300 mHz - 400 gHz). This range should not be confused with the modulation rate (carrier frequency) of the remote control. The remote control codes are sent to the receiver using the modulation rate.
