DLMS/COSEM 

Technologies provide data transmission by power supply lines. There are several different PLC technologies: for data transmission over high-voltage power lines, telemetry data transmission and broadband data transmission over low-voltage networks. The technology is also an international open standard focused on global application. The mesh network topology is used. The data transfer speed is not high, to 35 kbps (CENELEC)/128 kbps (ARIB).

An international standard of digital cellular communication based on which it is possible to deploy AMR/AMI in the existing mobile operators networks without creating own infrastructure, which is the main advantage of such systems.

A cellular communication standard for devices with a small amount of data. The existing mobile operators’ infrastructure is used for the NB-IoT communication standard. The network is deployed inside the main LTE baseband or outside the baseband between neighbouring LTE carriers.

A highly reliable standard for wireless low-power private networks in the unlicensed 868 MHz band. It allows transmitting small amounts of data at a distance of up to 15 km in the line of sight and 1.5 – 2 km in densely built-up urban areas.

Automatic Meter Reading (AMR) and Advanced Metering Infrastructure (AMI) are based on DLMS/COSEM data transfer protocols. These technologies are changing the way electricity data is collected and managed.
