OMS LPWAN

OMS means "Open Metering System" and is a manufacturer-independent and open communication standard for the collection and transmission of metering data from the energy and utilities sector. OMS is the only standard in Europe that integrates all data such as electricity, heat, water and gas, including submetering, into one system. This means that data from different metering products can be exchanged between consumption processing systems. OMS is based on European standards and was developed by the industry as a uniform protocol and data format to enable interoperability between metering devices. The use of OMS enables an open market for metering devices, better data transparency and easier integration of the corresponding devices for suppliers and consumers.

With Generation 5 of the OMS specification, annex Q enables the development of interoperable Low Power Wide Area Network (LPWAN) solutions for OMS end devices and gateways. OMS LPWAN defines a radio protocol specifically designed for metering applications that require long range and reliable communication, as well as long battery life. The protocol can also be used for other IoT applications, such as smart city or building applications, which also require long range and low energy consumption.

In OMS LPWAN, the two available modes "burst mode" and "splitting mode" on the "physical layer" (PHY) are explained. The splitting mode is based on the European ETSI standard TS 103 357. The differences between the two PHY modes offer the most suitable solution depending on the individual use case. Splitting mode is characterized by longer ranges and greater robustness as well as significantly greater scalability compared to other modes. The mode also has a short burst length.

The higher scalability in particular means that data from many more meters can be received with one base station for smart metering applications.  This saves costs and future-proofs the investment.

Our base station solution supports multiple standards for smart meter applications. With two phy-layer decoder and only one front end, mioty can support wMBus and mioty4OMS. Thanks to the software-defined radio (SDR) solution, the full potential of the technologies can be utilized. 

Supported profiles include: 

• mioty basic sensor (ETSI - Fix Mac)
• mioty4OMS:
  
  • OMS LPWAN Splitting (OMS 5, UL-S1+S2) 
  • OMS over mioty 
• wMBus (OMS 4):
  • Mode C1
  • Mode T

The base stations can be equipped with the new functions in the field via a software update.
