4.3.- PLC
The CirLAMP Manager uses PLC technology to communicate with the nodes (CirLAMP
Nodes) through the electrical network.
PLC (Power Line Communications) transfers data via the electrical network using advanced
modulation technology.
The PLC frequency bands are dened by different committees: FCC for North America and
Canada, ARIB for Asia and Japan and CENELEC for Europe.
The CirLAMP Manager works on Band B, from 95kHz to 125kHz, dened by CENELEC.
(European Committee for Electrotechnical Standardization).
