Electricity meters operated on Circuit Switched Data (CSD). We needed to fetch data from remote locations across the state and load it on to the main server; and do this securely to poll the data for automated bill generation.
Vodafone engineered a novel system integrating the use of SIM cards with secure meters to capture energy consumption data. Data was pulled automatically and the same was charged to the end customer.
We placed (CSD) operated meters all over the state and placed Vodafone SIM cards in them. These SIM cards helped pull data from distant division offices. The data was then captured from the server for billing purposes.
