    What is Broadband Over Powerline?

    High-speed, long-distance data transfer on powerline (medium & low voltage)

    Enabled by advances in signal processing and chipset speeds

    Connect to Internet via backhaulsuch as fiber, often at substation

    Data transfer typically at frequencies between 3 MHz to 30 MHz

    Known as BPL or access BPL

    It worksAs demonstrated in field trials and recent commercial deployments

    Its fast Speed competitive with cable and DSL. Main.Net at

    286 800 kbps in Manassas, VA. Some vendors > 2 Mbps. Second generation equipment, new chipsets faster.

    Speed is symmetrical Increased standardization

    (e.g., HomePlug*, IEEE P1675) Proving business case the next step.
