For secure transmission, the smart meter will be assigned to a smart meter gateway in future. It supplements the digital meter with an encryption unit which encodes the sensitive consumption and generation data in one complex process. The strict specifications for developing the smart meter gateway come from the Federal Office for Information Security (BSI) in Germany.
The smart meter gateway is equipped with two interfaces for connecting to the outside world. One of them is a WAN port (Wide Area Network). This is used for communicating with the energy provider, such as by using a G3-PLC modem. The other one, the HAN interface (Home Area Network), is designed for the in-house connection. One of the features it provides is to enable innovative monitoring of the meter for end customers, such as by using an app for smartphone and tablet.
The challenge when integrating in-house applications into the smart grid stems from the inconsistent networking of many buildings. A reliable, building-wide network that connects every component is only available in very rare cases. In no time, devolo in-house Powerline creates a secure and stable network available throughout the building. This is achieved by modulating a signal for data communication onto the household electrical wiring, without impeding its original purpose. At the same time, a connection to the home network enables the use of innovative metering services via smartphone and tablet.Technology
