Which band is more suitable for industrial remote controls, 433MHz or 470MHz?

Detailed Answer

Both 433MHz and 470MHz are legal license-free micro-power bands in China. 433MHz is the most widely used (a large number of wireless devices), so the probability of co-channel interference is higher; the 470MHz band is relatively cleaner, and because 470MHz has a shorter wavelength and slightly better diffraction performance, it suits complex metal environments. The LIDER LD series uses 470MHz, with a stable measured control distance of 200 meters; some XINGJIA models use 433MHz. Conclusion: for factories with many devices, 470MHz is recommended; in open spaces, either band works.
