Smart grids combining power systems and ICT require bidirectional links between the utility side and the demand side, and smart meters are gaining attention as a key device for maintaining such links. A smart meter must provide the functionality to implement such bidirectional control and linkage. Murata offers products incorporating exclusive technology that supports this functionality. Wireless communication is essential to the operation of smart meters. With products such as Wi-Fi and sub-GHz wireless communication modules, and 3D-sensing AMR sensors for detecting illicit magnetic fields, Murata is helping customers with smart meter development, from the concept stage through realization of the finished product.
