Hello, They are usually called PLC/PLT Power Line Carrier systems. On the ones I have seen conducted emissions are exempt in the US, carrier current system, and the radiated is usually done at several typical locations (houses). All the manufacturers I have talked to would like to be able to do measurements on a OATs but have not successfully convinced the FCC that it is possible. I have not seen any that meet the CISPR22 conducted emissions limits but they are getting into Europe by way of a TCF.
The interference caused by PLC is a HOT topic in Europe - Next week I will attend a CENELEC/ETSI standards meeting where they are coming up with in-situ limits for installations.
