What frequencies do industrial remote controls use?

Detailed Answer

Common frequencies for industrial remote controls: 433MHz (mainstream in China, strong penetration), 470MHz (used by the LDER LD series, good diffraction and long range), and 2.4GHz (some XINGJIA models, license-free, wide bandwidth but weak penetration). The 433/470MHz low bands suit complex environments, while 2.4GHz suits short-range high-bandwidth scenarios. Frequency choice affects range and anti-interference: low frequencies diffract better and reach farther; high frequencies have wide bandwidth but are easily blocked and absorbed.
