运用电力线实现以太网的芯片组,无须架线,简易。能够上网、内部互通。
Powerline integrated circuits make use of existing in-home AC electrical wires for transmitting digital data at high speed.
The AC powerline network can be a harsh environment for data communication. To compensate, System uses orthogonal frequency-division multiplexing (OFDM) in the 4.5 to 21 MHz band and a sophisticated forward error correction scheme to provide reliable data transmission.
System powerline chips also address network security risks by encrypting data to create a private Logical Network in the home. Password-bound encryption keys, private to the home network, are used to encrypt each message as it is sent and decrypt data as it is received. Even if data is intercepted outside the home, it remains secure.
There are a number of features that distinguish it
