Pain Points and Challenges

1. Geographical Limitations: Only supports the European CENELEC A frequency band, failing to meet the network access requirements of global markets such as the Americas (FCC) and Asia (ARIB), restricting overseas expansion.
2. Environmental Vulnerability: Insufficient stability in harsh grid environments such as strong impulse noise, making it difficult to adapt to complex scenarios like medium-voltage distribution networks.
3. Single Business: Originally designed for meter reading, it lacks support for high-bandwidth services, IP-based operations, and multi-device access, making it difficult to meet the evolving needs of smart grids.

Technical Principles

Based on the ITU-G.9904 international standard, a narrowband power line carrier communication system is built using OFDM core technology. Version 1.4 upgrades and optimizes on the mature architecture of v1.3.6: the physical layer expands the frequency band range, adds two robust transmission modes, introduces repetition coding technology, and optimizes parameters such as FFT to improve anti-interference capability and transmission rate; the MAC layer integrates time slot structure, optimizes superframe order, adds guard intervals, flexibly adjusts frame length and time slot length, adapts CSMA/CA algorithms with different parameter configurations, and adds a KeepAlive mechanism; the network layer adds IPv6 protocol support, enabling compatibility with various devices while maintaining backward compatibility with v1.3.6; the bottom layer builds a security protection system through 128-bit AES-CCM authentication encryption.

Innovation/Features

1. Globalization & High Performance:
   Global Frequency Pass: Frequency extended to 470kHz+, supporting CENELEC, FCC, and ARIB standards simultaneously—one solution fits the world.
   Double Speed: Through multi-channel bonding and other technologies, the theoretical maximum rate is increased to 1Mbps, supporting richer data services.
2. Super Immunity & High Reliability:
   Robust Transmission Mode: New Robust DBPSK/DQPSK modes, using repetition coding and other techniques, achieve up to 14.5dB performance gain in harsh noise environments, ensuring rock-solid communication.
   Enhanced Link Maintenance: New hop-by-hop acknowledgment KeepAlive mechanism precisely locates and repairs weak links.
3. Future-Oriented Network Architecture:
   Native IPv6 Support: Enables terminals such as meters to directly integrate into IP networks, paving the way for advanced applications like remote control and distributed energy monitoring.
   Flexible Networking: Supports multi-channel scanning and binding, adapting to large-scale, complex topology distribution networks.
