The country has the goal to equip 95% of its households with smart meters by the end of 2019, representing 5.7 million points.
Austrian utilities have set G3-PLC as the preferred data transmission protocol, one of the most commonly used for smart metering, with more than 50 million metering points installed in Europe.
As Stephan Krähenbühl, Landis+Gyr’s Head of the Customer Project Management Office, pointed out in an Engerati webinar in June 2016, “compared with the earlier PLAN technology, the G3-PLC offers several benefits”. Among these, the increased band (up to 500 kHz) that Orthogonal Frequency Division Multiplexing (OFDM) based PLC technology or G3-PLC offers is key to covering additional functionalities, like its security or the demand response functionality for load management.
Krähenbühl claims the communication with the data concentrator is established much quicker, allowing a faster rollout and a shorter time to tackle communication and technical issues in the field. In fact, Krähenbühl stated that “the G3 communication technology was among the main reasons why Netz Burgenland chose Landis+Gyr as partners”.
According to Kiijärvi, G3-PLC also enables handling of large data volumes, improved performance, and adds reliability. “So, when we look at G3-PLC we look at four different values: speed, stability, security, and connectivity”
For any PLC communications network, the greatest challenge for its performance is a high level of noise at the DC. Measurements have shown that despite this noise G3-PLC has been able to maintain communications, whereas other PLC communications technologies have experienced difficulties.
