When the number of meters reaches millions of units, it becomes apparent that it is very difficult to achieve secure and reliable communication with control centers. Even more so when some of the functions associated with the Smart Grid concept need communications in real time. In such situations, telecommunications are a great challenge and new smart meters play a key role in successfully facing this new challenge.
PRIME (Powerline Related Intelligent Metering Evolution) calls for a new public, open and non-proprietary telecommunications architecture that will support the new AMM functionality and enable the building of the electricity networks of the future, or Smart Grids.
PRIME is base on OFDM multiplexing in CENELEC-A band. The end objective of PRIME is to establish a complete set of standards on an international level that will permit interoperability among equipment and systems from different manufacturers. In this way, competition in the metering market will occur for the benefit of consumers.
Unlike other commercially available solutions, the components of this new architecture (protocols, modulation systems, data formats, etc.) will not be subject to Intellectual Property Rights.
In this respect, the specifications of the Automatic Meter Infrastructure will be so detailed that any participant will be able to bring to the market interoperable solutions.
PRIME defines lower layers of a PLC narrowband data transmission system over the electric grid. All the system has been created to be low cost and high performance.

The reference model is based on protocol layering:

| |
Convergence Sub-Layer
Classifies traffic associating it with its proper MAC connection. This layer performs the mapping of any kind of traffic to be properly included in MAC SDUs. Multiple CSs are defined in order to accommodate different kinds of traffic into MAC SDUs. |
|
MAC Layer
Provides core MAC functionalities of system access, bandwidth allocation, connection management and topology resolution. It has been defined for a connection oriented Master-Slave environment, and optimized for low voltage power line environments. |
|
PHY Layer
Transmits and receives MAC PDUs between Neighbor Nodes. It is based
on OFDM multiplexing in CENELEC A band and reaches up to 130 kbps raw data rate. |
