[sci.electronics] power-line data transmission

lharris@utgpu.UUCP (06/07/87)

Hi.  There was some discussion in this group a while back about transmitting
data through the AC power system (like the BSR stuff).  I missed getting most of
it then and I need some information now.  I know that the BSR str
stuff transmits using a frequency of 120KHz and only during zero-voltage
crossings but is it OK to transmit during the whole AC cycle.  Also what is the
optimum carrier frequency to use?  I know this has been on the net before so 
please mail to me so as not to bore others..
Thanks in advance
