ALTTC/DX/IBB OV/AKN 26


PLC-Power Line Communication Also referred as BPL (Broadband over Power

Lines)

Can provide broadband Internet accessthrough ordinary power lines

Most extensive networks in the world,surpassing the phone network as well as the

cable network in size and coverage Suffers from technological challenges due to

interference with noise, radio and television etc.
