Introduction
- G3-PLC is an open power line communication module designed for smart grid communication. Its physical layer is based on OFDM modulation and complies with G3 standards.
- G3-PLC have high-speed communication, strong anti-interference ability, the communication speed is much faster than traditional PLC.
- The module has very low maintenance cost. Metering reading network operating with G3-PLC is automatically constructing, automatically addressing and route maintenance.
- It can be easily integrated in smart electric meter to provide the AMI function.
- DC2-PSR4 could be adopted to Single Phase Electric Meter.

Features
1. OFDM-based PHY (BPSK, QPSK, 8PSK) makes efficient use of the spectrum
The "robust" mode of module improves communication under noisy channel conditions, operates at -15 dB SNR.
2. Compliant with world regulatory bodies such as CENELEC, ARIB, and FCC (10 kHz - 490 kHz)
Auto switch between CENELEC-A and FCC to adapt different scenario according to the DCU.
3. Standards based — pre-standard in IEEE, ITU, IEC/CENELEC and IEC/SAE
- Two layers of forward error correction (FEC) for robust data communication in harsh channels.
- Adaptive tone mapping for optimal bandwidth utilization.
- Channel estimation to select the optimal modulation scheme between neighboring nodes.
- IEEE 802.15.4-based MAC layer well suited to low data rates.
- 6LoWPAN adaptation layer to transmit IPv6 packets over powerline channels.
- Coexistence with older S-FSK (IEC 61334), and broadband IEEE P1901 and ITU G.hn standards.
- Supports IPv6 to allow Internet-based energy management systems and applications.
4. Security
AES-128 cryptographic engine for optimum data security.
