A technology called Power Line Communications (PLC) makes use of the electrical infrastructure already in place to set up communication networks.
This study suggests an Orthogonal Frequency Division Multiplexing (OFDM)-based design for the Physical Layer (PHY) of a PLC transceiver that is based on the IEEE 1901 standard for Broadband PLC.
The developed system can accommodate data speeds of up to 107 Mbps and is synthesised on a Xilinx Spartan-6 FPGA device.
The Global PLC Transceivers market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
Half-duplex, asynchronous data communication over AC power lines is provided by the MAXIM INTEGRATED MAX2992 powerline communication (PLC) transceiver baseband modem at speeds of up to 300kbps (full FCC band data rate).
The 32-bit MAXQ30 microcontroller core from Maxim is used in the system-on-chip (SoC), MAX2992, to merge the physical (PHY) and media access control (MAC) layers.
Together with the MAX2992 G3-PLC firmware, the MAX2991 integrated analogue front-end transceiver and MAX2992 comprise a comprehensive G3-PLC-compliant modem solution.
The MAX2992 enables reliable data communication using the electrical power grid by utilising OFDM techniques with DBPSK, DQPSK, and D8PSK modulation and forward error correction (FEC).
The design offers built-in resilience to impulsive noise, durability in the face of group delay, and flexibility to frequency selective channels.
The MAX2992 has a customizable tone notching system to enable regulatory compliance. This enables the modem’s transmit spectrum to have some frequency bands notched.
Additionally, this capability offers a different approach for dealing with the coexistence of legacy FSK-based PLC systems and other narrowband transmitters.
