White Paper: Power Grid Private Wireless Network -- The Future of Critical Communication in the Power Sector

Huawei and the 450 Megahertz (MHz) Alliance released a white paper on private wireless networks for Brazilian power grids. The document links critical communications to the operational needs of distribution networks and outlines a technical and regulatory roadmap.

The release frames grid modernization as relying on digitization of infrastructure and broad integration of renewable energy sources. It says communication in this setting becomes a foundation for an intelligent, secure, and resilient power grid, with distribution networks described as facing the highest connectivity demands.

The white paper focuses on private wireless networks, including private Long Term Evolution (LTE) and 5G, and describes them as addressing limitations of legacy technologies. It connects these networks to capabilities such as automation, real-time monitoring, and operational reliability, while citing requirements for latency, security, and scalability.

The document was launched at the UTCAL 2026 summit in Rio de Janeiro on March 17. The release says the paper includes discussion of use cases such as teleprotection, smart metering, field control, and predictive monitoring, and it provides a link to download the PDF.
