Cemig and Huawei Launch 450 MHz Private Wireless Network in Brazil

Cemig and Huawei have partnered to deploy a 450 MHz private wireless network in Brazil. This initiative addresses the shortcomings of relying on public networks for power grid operations, particularly in remote areas. Public networks, with only 50% coverage, often left distribution devices offline, especially during rainy seasons, causing operational delays and economic losses.

The new private network enhances connectivity to 99% and boosts communication reliability to 99.99%. This improvement significantly uplifts Cemig's power distribution service, mitigates business risks, and secures favorable investment returns by meeting regulatory requirements. Additionally, it supports future technologies like smart meters and microgrids.
