Huawei has launched a 4.5G-based eLTE-DSA (Discrete Spectrum Aggregation) solution for commercial use, to help global power companies build the "last mile" of the neural network for power grids.
As the energy industry is transforming, requirements are changing and the communications network for electric power IoT must provide more comprehensive coverage for a wide range and growing numbers of terminals and devices. Reliable, flexible, ubiquitous, and economically efficient, the wireless private network has become the best means of building the "last mile" of the neural network for power grid.
The traditional VHF (30~300MHz) / UHF (300~3000MHz) narrowband discrete spectrum used in the energy industry cannot meet the requirements for power IoT development because it is commonly based on data radio technology, which causes technical bottlenecks due to long-latency, small capacity, insufficient bandwidth, and high power consumption, says Huawei.
In China, 230MHz is a discrete spectrum dedicated for the power industry; it is also a VHF narrowband discrete spectrum. This helps to build the large-scale "last mile" of the power grid efficiently, and to construct a world-leading power IoT which Chinese power companies have been trying to explore.

Huawei and the State Grid Corporation of China (SGCC) are jointly innovating in standards, products, R&D equipment, and service tests based on the 230MHz eLTE-DSA solution.
