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-PTR4 could be adopted to Three Phase Electric Meter.

Technical Parameter

Standard

G3 PLC/ IEEE1901.2/IEEE802.15.4-2006/6LoWPAN/ITU G.hn/S-FSK (IEC 61334)

Features

1. High Efficient

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. World Standard

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. Certificate based

- 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.

5. Mesh routing protocol to determine the best path between remote network nodes

- The maximum nodes 1024

- The maximum hops 14

6. Over the Powerline update Firmware (OTP)

7. DLMS interface with meter

8. G3-PLC alliance Certified products

Situation

For Three Phase Smart Electric Meter, Data Concentrator, or other communication instruments.
