Main features (1)
Applies to a large number of interfaces: MI1, MI3, CI2-SI1, MI5
Robust PLC communications:
– PHY layer using BPSK modulation.
– LLC layer based on IEC 61334-4-32
Efficiency :
– Table-based data model
– very short messages optimized for PLC and wireless IP communications
Strong data security: encryption and authentication (128 bit AES).

Main features (2)
Flexibility: Custom tables
Comprehensive approach: Application layer used for
• Meters and More lower layers,
• TCP/IP-based networks and
• Optical handheld device for Operation and Maintenance.
Low cost
Low consumption

Data security
Application Messages encryption, authentication, and “playback attack” protections: oriented to obtain self-referencing/consistent messages without the necessity of using access authentication procedures.
Shared symmetric keys (128 bits) model with same key for messages encryption and authentication.

Performance
Table based data model, minimum message overhead and efficient data link layer lead to very short messages (frames) and low error rates, increasing overall throughput.

Meters and More AISBL
Meters and More is a non-profit organization under Belgian law with the following objectives:
• Adopt, maintain and evolve Meters and More open communication protocol for smart metering solutions.
• Promote the existence of a range of interoperable devices, applications and services by promoting open industry specifications.
• Provide a certification process to assure product compliance with Meters and More specifications.
• Support the smart metering standardization.
• Drive Meters and More protocol evolutions by creating a place where the Association Members may propose and evaluate enhancements and approve them within well-defined open rules.
