WM Systems - Innovation in Smart IoT SystemsWM-E Broadband PLC External Modem - WM Systems LLC - Innovation in Smart IoT systems : WM Systems LLC – Innovation in Smart IoT systems

Cost-effective data collecting and forwarding of wired meters of the power line network.

The data transmission is performed through the wired modem, which is communicating on PLC network with the meters and centre (server-side).

The communication can also be routed through the Ethernet by transparent mode to the server IP – without coupling (without a concentrator or gateway).

By the remote switch of the meter, the device is capable of changing its operation and tariff modes.

The device and the solution are also useful for G3 and PRIME networks.
