Do RF remotes work through walls?
RF remotes use specific radio frequencies, typically a license-free 2.4 GHz bandwidth, to transmit a signal to a receiving device. The signals are able to be sent through objects like walls and furniture, extending the remote’s range.
Can I use my phone as a RF remote?
Many Android phones come with an embedded infrared “blaster” that uses the same technology as old-school remotes.

Can iPhone transmit RF signal?
1 Answer. In my experience with iOS there is no device with RF chipset. So for iOS the answer is NO.
Can I use my phone as remote without IR Blaster?
Introduction: Control TV With Any Phone (Even Phones Without IR Blaster) … Basically the phone sends signal to HC-05 (bluetooth module) and further bluetooth module sends the characters to arduino’s serial port and arduino sends particular IR signal decoded from your remote!! It works with all TV remotes!!
