PLC and Hybrid communication solutions provided by ADDAX are very reliable and without a serious effort allow a stable communication channel with 98% of meters or more. However there are situations when PLC or RF communication is impossible or economically not feasible. For instance if there are less than 5 electricity consumers per distribution transformer, or when smart meters are provided to large consumers only. In such cases it is advisable to use P2P communication, i.e. direct communication channel between meters and Head End Software.
