What's HD-PLC Adaptor?
Introducing the HD-PLC Adaptor
The new HD-PLC Ethernet Adaptor makes an exciting breakthrough in home network systems. It brings true satisfaction by solving the problems of slow data transmission, difficult settings, insufficient safety, and limited applications. Using just the ordinary power outlets in your home, Panasonic's HD-PLC Ethernet Adaptor will let you easily enjoy the world of the Internet.
HD-PLC Technical Data
Power Line Communication (PLC) is a technology that uses power lines to both supply electric power and transmit data. Electricity travels in large, slowly changing waves (figure A), while data signals move in small, quickly changing waves (figure B). Since these waves travel at different speeds, there is no mutual interference when they travel together (figure C). This makes it possible to send data signals through power lines, and access the Internet from power outlets. Original Panasonic HD technology uses this principle to provide the large data transmission capacity and high speed of the HD-PLC Ethernet Adaptor.
HD-PLC is a proprietary Panasonic technology that enables high-speed, high-quality, stable data transmission.
The HD-PLC PHY (physical layer) uses Wavelet OFDM (Orthogonal Frequency Division Multiplexing) technology to achieve highly efficient transmission with characteristics that exceed even FFT (Fast Fourier Transform)-based OFDM systems. Wavelet OFDM features greater speed efficiency and forms a deeper "flexible notch" that prevents interference with shortwave and other broadcasts. This is achieved by appropriately modulating the sub-carrier and by including no guard interval.
The BL-PA100 quickly detects fluctuations in the data transmission path caused by noise and other factors, and determines the optimal data transmission method to enable maximum throughput at that point in time and achieve stable communication performance. Strong error correction coding and a diversity mode also boost reliability in poor-quality home power lines.
