LMN

« Back to Glossary Index

Simply explained: The Local Metrological Network (LMN) is the connection technology between the Smart Meter Gateway (SMGW) and the individual meters. This local networking is essential for the encrypted exchange of measurement data within a smart metering system. The LMN enables communication via various interfaces, including wireless short-range radio technologies such as Wireless M-Bus or serial connections.

Advanced explanation:

A key feature of LMN technology is the support of so-called 1:n installations. This means that several meters can be connected to a single SMGW, which is particularly advantageous in scenarios with several meters such as apartment blocks or commercial properties. Here, all meters can be read via a central SMGW and the data forwarded accordingly.

 

The need for LMN technology: efficiency and scalability

The need for LMN technology arises from the increasing complexity and growing scope of the smart meter rollout. The efficient networking of individual meters with the SMGW not only enables precise and secure data collection, but also contributes to cost efficiency. Significant savings can be realised by using high-quality LMN components, as a single SMGW can control up to 32 meters in an apartment building, for example. This significantly reduces hardware and installation costs.

In addition, LMN technology enables flexible and scalable networking that can be adapted to the specific requirements of different applications. The support of different communication interfaces and the ability to network meters that are located far apart make the LMN a central component for the efficient implementation of the smart meter rollout.

 

Applications for LMN technology: versatile and future-orientated

LMN technology is used in various areas and offers a wide range of possible applications. Typical applications include

Apartment blocks: Here, all meters in a building can be read via a single SMGW, making installation and operation simpler and more cost-effective.
Commercial properties: In businesses and industrial plants, where multiple meters are often required, the LMN enables efficient networking and centralised data management. If the right technology is used, it is even possible to network electricity meters in different buildings.
Smart grids: In the context of smart grids, which enable the dynamic distribution of renewable energies, LMN technology is a decisive factor for the integration and communication of the various metering systems.
