RF Code first began offering products in the 303MHz range (US & Japan) and later in the 433MHz range (US & Europe). These signal frequencies are limited, low-power, unlicensed ranges in the ISM (Industrial, Scientific and Medical) portion of the UHF band. RF Code began offering 433MHz products because of acceptance of this frequency in Europe. 433MHz is also the frequency which offers optimal performance in crowded environments such as offices, data centers, and hospitals.

Generally, radio signals at lower frequencies travel farther than those at higher frequencies. Lower frequencies also benefit more from the effects of reflection and refraction which makes them more suitable for applications in crowded environments. For example, the 433MHz wavelength is approximately 69 cm vs. 10 cm for 2.4GHz. The larger wavelength of the 433MHz signal allows it to diffract around obstructions that might be found in a typical, crowded operating environment such as an office or warehouse. At frequencies of 2.4GHz and above, the signal is susceptible to obstructions, creating blind spots (areas of no coverage). Higher frequencies also require more power.

Why is the 433 MHz frequency used for remote control applications?

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
