PLM-1 is a digital modem implementing a half-duplex transmitter/receiver for powerline communication (PLC). Designed as an ASIC, the device is a very efficient solution for cost sensitive, medium data rate applications. The PLM-1 uses Ariane’s patented narrowband FSK (Frequency-Shift Keying) modulation technique. The information is encoded by shifting the frequency of the carrier signal between two discrete values in a very narrow range. Featuring complete media access control (MAC), Forward Error Correction algorithm, programmable parameters and simple external circuits, PLM-1 provides reliable communication and allows designing more cost-effective PLC transceivers than possible with any other solution.
