Why does RF Code use 303MHz and 433MHz frequencies?
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.
