Using a PLC to connect a smart meter with a concentrator is the most beneficial way for any DSO. And, as known, there are two main standards for transmitting information using PLC.
ADD Grup is a member of major alliances PRIME and G3-PLC, which allows creating meters regardless of the standard demanded by the customer.
The main specifics is that G3-PLC co-exists with PRIME and S-FSK IEC 61334-5-1 on a single platform, where the switch between these technologies is done only through firmware change without any need for replacement of meters or data concentrators.
