No.
Go for 2.4 ghz.
Smarthome (home automation superstore) has remote control extenders and lets you know which size MHz Kit you will need to purchase based on the system you are using.
try for 455mhz rf remote transmitter ,455 mhz remote controls are not available in the market
Mhz stands for Mega Hertz
Queen Beatrix International Airport (AUA) Oranjestad, Aruba Air Traffic Control 121.600 MHz AM Beatrix Apron Control 127.100 MHz AM Curacao Control 120.900 MHz AM Beatrix Tower ATIS: 132.1 MHz GND: 121.9 MHz MISC: 123.1 MHz (SEARCH AND RESCUE)
Personaly, i have to R/C cars that are 27 MHZ and 49 MHZ and my 49 MHZ goes faster than the 27 MHZ. but the 27 MHZ has much more control than the 49 MHZ.
I don't think so, you can use 433 Mhz Remote Controller when there is no WIFI. Also, every appliance will have a local control, too.
Remote control employs a frequency modulation (FM) radio frequency of 433 MHz transmission that has a strength range of 400 mt outdoors or 200 meters indoors [ through a wall ] to operate any electronic /electric relay driven gadget through a radio frequency decoder.433 MHz frequency can be produced by a small (size of a postage stamp) simple 4 bit chip that has no complicated circuit and better than complex inconvenient ones for higher range. 433 MHz frequency modulation radio waves are best suited for short range applications produced from compact micro circuit and therefore useful for short range use
The WowWee Dragonfly can be used around RC cars, but make sure it's switched to the alternate frequency to avoid interference.
It communicates with the Control Panel using the 345 MHz wireless frequency.
VHF = "Very High Frequency" Formally, radio frequencies from 30 MHz to 300 MHz. (Wavelengths between 1 meter and 10 meters)
