Power Line Communication

Power Line Communication is a fairly recent technology which is used to transfer data and establish means of communication at broadband speeds over transmission lines. The technology is widely also known as Power Line Telecommunication (PLT) or even Power Plus Communications (PPC). The technology uses advanced modulation technology which super imposes the data signal of high frequency over the low frequency power signal.
The research into PLC started off in the mid 1980’s in the band range of 5-500 KHz and was developed for only unidirectional communication but with time the system has been advanced to permit bidirectional transmission of data signal.
