In the transformer areas where mobile communication signal is not covered or poor, the data concentrator fail to report the collected data via public network.

To settle the above problems, Topscomm has achieved to transmit the data on terminal devices to the host signal converter where with good signal via Topscomm high speed PLC communication solution, and then report to the master station. The biggest advantage of this solution to reduce the workload of on-site construction.
