eLTE-DSA Smart Grid Solution

Traditional power grid industries are facing challenges during the process of developing into the energy Internet in many different aspects, including generation, transmission, distribution, and assumption. For example, the power grid control has extended to the customer end, the number of control points has increased to millions, and the real-time requirements are more strict. The data collection represented by smart meters is exploding, and the frequency of acquisition is getting higher. All of these changes have imposed stringent requirements on grid communication networks, which should support high reliability, low latency, wide coverage, low power consumption, and large connections.

eLTE-DSA (Discrete Spectrum Aggregation) is a converged wireless private network solution based on 4.5G technology, adapted to discrete narrow-band spectrum features and implemented by discrete spectrum aggregation technology. This solution has the advantages of high security and reliability, strong anti-interference ability, low latency, large capacity, low power consumption, etc. It can meet the needs of diversified service access, supporting precise load control, distribution automation, power information collection, charging pile management, distributed energy management, and other services.
