With the Smart Grid technology, the energy generation and distribution process will be more robust, efficient, and economical rather than higher power generation. In addition to increasing the innate intelligence of the grid itself, the smart grid is rapidly evolving into an intricate network with multimodal communications methods. To address this growing need, more ARM-based solutions are being leveraged to control the smart grid. With low power and energy-efficient designs that are ideal for this market, ARM processors help these complex networks increase security functionality, intelligent support for application and communication stacks, and communications functions for home or building connectivity.
