The Corinex SmartGrid 200 Compact Gateway can fulfil a number of functions within an AMI network: it can act as a Head-End node, a communications bridge between meters and the NOC, or a BPL signal repeater. The gateway supports up to 1000 network elements i.e. meters and other gateways within a self-mapping, self-healing mesh network topology. Communications between the MDMS and the meters are bridged via the SmartGrid 200 Gateway, with an available Ethernet port for interfacing with a backhaul medium (e.g. ADSL, satellite, GPRS, etc.) to enable communications with the MDMS at the NOC. BPL communication with the meters can be achieved using either the gateway’s integrated three-phase coupler, or its coaxial port.
