Also found this information on a Toronto, Ontario, Canada company at:
http://www.cogency.com/B_htm/PBL3_B1_Tech.htm
"The AC powerline network can be a harsh environment for data communication. To
compensate, Cogency uses orthogonal frequency-division multiplexing (OFDM) in
the 4.5 to 21 MHz band and a sophisticated forward error correction scheme to
provide reliable data transmission."
