S130N-ISI Full-Stack Solution in tight collaboration with cloud platform：redefine PLC Development Paradigms

1. What is PLC?

1.1 Technical Definition

PLC (Power Line Communication) is an innovative communication technology that utilizes power lines as a natural transmission medium. By advanced signal modulation techniques, it superimposes high-frequency data signals onto standard power-frequency currents, enabling simultaneous power delivery and data communication. This technology eliminates the need for additional communication cables, it can be deployed directly over existing power lines to establish communication systems—truly achieving the dual functionality of "one wire, two purposes.

1.2 Core Technical Principles

Signal Modulation Mechanism: Adopting modulation techniques such as Orthogonal Frequency Division Multiplexing (OFDM) and Phase Shift Keying (PSK) to encode raw data signals into high-frequency carriers (1–30 MHz). This modulation employs frequency-domain superposition to effectively separate high-frequency data signals from 50/60 Hz power-frequency currents, ensuring interference-free transmission between two signals in PLC.

1.3 Coupling and Decoupling System:

Signal Injection: At the transmitting end, a dedicated coupling device injects high-frequency data signals into the power line safely and efficiently, enabling synchronized transmission of communication signals and power.

Signal Extraction: At the receiving end, a bandpass filter system precisely filters out power-frequency, extracting the 1–30 MHz high-frequency communication signals completely, original data is then restored via demodulation.
