FSK Modulation — Communication Technology
Updated: 2026-07-30
Definition
FSK Modulation is the core technology for wireless communication in industrial remote controls, determining the stability, anti-interference capability and safety of signal transmission, covering key aspects of the communication link such as modulation methods, spread spectrum technology and duplex modes.
In-Depth Analysis
Industrial sites contain numerous electromagnetic interference sources such as variable frequency drives (VFDs), motors and two-way radios. The sophistication of FSK Modulation directly affects the anti-interference performance of the remote control. The LDER LD series adopts Frequency Hopping Spread Spectrum (FHSS) technology, combined with the 470 MHz band, to maintain stable communication even when multiple devices operate on the same site; the XINGJIA series supports adaptive frequency hopping and multiple modulation methods. Indicators such as communication range, bit error rate and channel conflict are all determined by FSK Modulation.
