Subject: "Networking over Power Lines: EMC Considerations" 

Speaker(s): Thomas N. Cokenias from T. N. Cokenias Consulting 

The electric power grid and household electrical wires are harsh EMC 
environments, yet they have been attractive as communications media because 
they are everywhere. Until recently, only low speed data and intercom voice 
communications were practical over household wiring, due to the high noise 
levels presented by motors, dimmers, relays, switches, and other noise sources. 
Overhead wires from power pole to the house are subject to even higher levels 
of noise from local arcing and nearby radio stations. 

In the last five years semiconductor and software developers have come up with 
methods of modulation, Forward Error Correction, and medium characterization 
that make the power lines practical for interconnecting networks nodes and 
access points at ethernet speeds. Standards are being developed for throughput 
speeds of 200 MBps and the FCC has recently adopted rules for certification of 
broadband over power line (BPL) devices, while ETSI and CISPR have draft 
standards they are developing. 

The presentation will include an introduction to communications over 
powerlines, to standards in place and in development, the EMC concerns of the 
radio community, and EMC test procedures for power line communications systems. 

Tom Cokenias worked as an engineer at the FCC Laboratory in Columbia, MD. Since 
1983 he has held senior engineering positions at several EMC labs in the SF Bay 
Area. He is founder and principal consultant at T. N. Cokenias Consulting.
