Radio Focus Remote is a device to control a lighting console without actually being at it. RFR is an ETC proprietary product, essentially a wireless RFU, previously known as wRFU. Most major lighting manufacturers make a wireless, handheld RFU for their Mid to High end consoles. Some consoles such as the GrandMA & Strand Consoles can be controlled from smart phones. And some like the ETC Ion/EOS can be controlled by a laptop/computer plugged/wirelessly linked into the same network the console is in.
