Table 1 Comparison of existing smart meter and SNM.
From: A cost-effective smart metering approach towards affordable deployment strategy
Existing smart meter | SNM |
|---|---|
Need to replace the old digital meter with the new smart meter for smart metering | Upgrade the existing digital meter by adding an add-on device for smart metering |
Deployment cost is high since all houses fitted with new smart meters | Deployment cost is less since the cluster of houses is connected to one common SNM |
Maintenance and firmware updates are carried out separately | Maintenance and firmware updates are carried out only at SNM |
