Technology - Broadband Power Line 5 - Interference and Challenges


After discussing the best known objection to BPL access services: interference, this report examines the better established alternative technologies which BPL typically competes with, particularly those technologies which might be more easily deployed by a power utility. Finally, we discuss the barriers which BPL access systems must overcome if they are to achieve the long awaited wide adoption and low costs.
