Standards

Narrowband PLC is typically used for low-speed applications like Automatic Meter Reading (AMR) and Command & Control. Traditionally use of narrowband PLC for access between the utility and the customer site has been greater in Europe than in North America because of the higher number of customers connected to each low-voltage transformer. Therefore, the early international standards for customer access via narrowband PLC are mostly European-based.

Narrowband PLC Frequency Bands

The most broadly deployed Narrowband PLC solution employ relatively simple, but extremely cost effective FSK and B-PSK modulation techniques. Several interoperable standards have been developed based on these techniques, the two most notable being Lon and DLMS.

With the advancements in communications technologies, the first generation of FSK/BPSK based Narrowband PLC standards is being followed by a number of new initiatives. Most notably, Orthogonal Frequency Division Multiplexing (OFDM) has proven particularly effective, due to its inherent ability to adjust to the noise environment, resulting in a more robust and more capable communication network. As a result, a number of OFDM based initiatives, such as PRIME and G3-PLC have been evolving.

While the Narrowband PLC space continues to be fragmented among competing standards and proprietary implementations, the IEEE started in May 2010 P1901.2 working group, which defines an OFDM based Narrowband PLC standard that would provide convergence between PRIME and G3 and interoperate with several narrowband and broadband PLC industry standards.
