Re: Very confused about powerline communication - Let's disc
Hi 2wires:
The question is whath kind of things you wannadoo. If you want to control and monitor appliances, the ST7537 is the best choice cuzz it´s is a proven good and stable chi for pwrline comms, relatively cheap and useful over noisy lines.
Now, if you want to transmit something as voice or multimedia there are two possibilities.
a) use an add on circuit only for voice and gather the audio from powerline upon a command sent by host to st7537 system. You will end with a two carrier system, one for the ST and other for audio (one audio conection at once or a "broadcast mode" (all sistems blabbing something at once) for audio you can use the inexpensive LM567 or LMC567 better
This sistem is only usable for AUDIO only
b) If you want multimedia (audio video full duplex) you´ll have to switch to a kind of ADSL technologies such as drivers and modems, but this means a significant effort economical as well as technical.
To begin with I recomend to read a bit on this here:

very interesting use of adsl driver chips
Well, I hope you find this usefull
Cheers
