Official Announcement: Shenzhen Londian Wason Holdings Group Co., Ltd. Achieves DLMS IDIS Package 3 Certification – A Industry First with Dual Communication Modes
Shenzhen Londian Wason Holdings Group Co, Ltd. (hereinafter referred to as “Londian Wason”) is proud to announce a groundbreaking milestone in smart metering innovation: successful certification of the DLMS Compatibility qualification program – IDIS Package 3, the highest package of the DLMS/COSEM interoperability standard, with simultaneous support for G3-PLC and GPRS communication protocols in a single test session.
Key Highlights of the Achievement
- Package 3 Certification – Unmatched Industry Leadership
- Package 3 represents the most rigorous level of the DLMS IDIS certification, ensuring full compliance with advanced security, data modeling, and interoperability requirements. While most meter manufacturers currently hold only Package 2, Londian Wason’s accomplishment underscores its technical superiority and commitment to future-proof solutions.
- Dual-Protocol Integration – A industry first
- This certification marks the first time a company has validated both G3-PLC (powerline communication) and GPRS (cellular connectivity) within a single DLMS IDIS testing cycle. This breakthrough allows utilities to:
- Seamlessly cover diverse grid environments (urban, rural, and hybrid infrastructures).
- Reduce deployment costs by leveraging a unified meter platform for multiple communication needs.
- This certification marks the first time a company has validated both G3-PLC (powerline communication) and GPRS (cellular connectivity) within a single DLMS IDIS testing cycle. This breakthrough allows utilities to:
- Strategic Impact for Utilities
- The dual-mode capability addresses critical challenges in smart grid scalability, enabling:
- Reliable connectivity in areas with unstable cellular coverage (via G3-PLC).
- Flexible remote management for distributed assets (via GPRS).
- Utilities can now standardize on Londian Wason’s meters to future-proof their AMI (Advanced Metering Infrastructure) investments.
- The dual-mode capability addresses critical challenges in smart grid scalability, enabling:
