Mexican Power Company Deploys eLTE-IoT Network for AMI
Wednesday, July 11, 2018 | Comments

The largest power company of Mexico is using a digital communications network from Huawei as the nervous system for its advanced metering infrastructure (AMI) platform.

Huawei will implement an enterprise Long Term Evolution-internet of things (eLTE-IoT) network as the backbone for the AMI system. The open system is designed for ease of integration for collaborating partners to provide secure and cost-effective end-to-end (E2E) smart grid solutions.

Mexico implemented a new electricity law in 2014 that opened the national power grid to investment to promote competition for the generation and sales of electrical power. The openness and competition in the electric power sales market have led to a common demand of electric power sales companies for neutral third-party metering, which is used specially for large industrial and commercial users.

NetCity, owned by GOES, emerged against this backdrop to help electric power sales enterprises improve operations capabilities and solve problems such as difficult and slow fee collection, high line loss, poor management and low customer satisfaction. The AMI solution provides electric power organizations with a smart metering platform based on bidirectional high-speed communications that allows real-time transaction charges.

The power grid company facilitated additional support through a partnership with NetCity, a professional wireless IoT provider, allowing the utility to efficiently and cost effectively collect electricity consumption data from homes and businesses, reduce line losses and fee collection times, and increase revenue.

The eLTE-IoT network operates in the 902 – 928 MHz industrial, scientific and medical (ISM) frequency band, uses Third Generation Partnership Project (3GPP) 4.5-generation technology, and employs new features that comply with the laws and regulations for unlicensed spectrum, enabling backhaul communications for power metering for improved security, reliability, and network performance that exceeds published IoT requirements for AMI.

In the first quarter of 2017, the technical specifications of Huawei's eLTE-IoT platform were written into the Mexican National Industrial Communications Act, and in the second quarter of 2017, eLTE-IoT-connected AMI meters passed the admission certification and earned Huawei the contract for a phase one deployment.
