Broadband over Power Line died. BPL was the FCC's third pipe to the home, since every dwelling has electric power. (BPL also refers to using in-house electric wiring to run the LAN, like HPNA.) BPL had a couple of trials, mainly under 500 homes. There was trouble passing the frequency through transformers. The AARL (ham radio operators) have been arguing for years that BPL bleeds into ham frequencies. Guess they won that fight, huh?
