How is E-Line Different?
Power line communication (PLC) is the broad term for impressing a modulated carrier signal onto an electric grid. Broadband over Power Lines (BPL) typically refers to the method defined by IEEE P1901 which is in contrast to E-Line's surface wave propagation and operation at much higher frequencies.
E-Line is a new surface wave transmission technique which differs from a previous one known as Goubau line where insulation around the conductor is required.

| BPL | E-Line |
|
- uses 2 conductors - restricted to frequencies < 80MHz - can operate on buried power lines - can interfere with other services - can be affected by other services - can be used in low-voltage HomePlug applications |
- uses a single overhead conductor - frequencies from 20 MHz through millimeter - data rates > 1 Gbps - operates at the native frequencies of many communication networks - low attenuation - allows distributed antenna system design - operates on medium-voltage power distribution lines without interference |
