Secured communication in the smart grid.
The devolo smart meter gateway (SMGW) is the central security component in the smart grid and ensures encrypted, BSI compliant data transmission between utility meters and gateway administration (GWA). It records both wired meters and wireless meters connected via Wireless M-Bus. The SMGW provides encrypted data to the GWA and authorised market participants over a WAN interface (Wide Area Network). The end customer can visualise consumption over a HAN interface (Home Area Network) and take advantage of utility provider‘s variable electricity rates. Moreover, network operators can use the HAN_CLS (Controllable Local Services) interface to control consumers and feeders.
