There's two sides to the interference issue mentioned by Mikerowaved. It seems that some systems were also susceptible to moderately powered transmitters.JamesAnderson wrote:There's one I've heard little about, and that's BPL, or 'Broadband over Power Lines'. The FCC approved that a couple years back, but have not heard of any BPL ISPs in Utah yet.
I'm of the opinion that it's too little too late. The interference issue can be solved, but the system is shared bandwidth and the speeds are not impressive. It needs amplifiers to go any distance so it's not well suited for remote/scattered areas (too much equipment for too few subscribers). But in areas where it can work well, it's competing against DSL and Cable. I also have my doubts about it's ability to scale. Nobody is going to run more power lines to get more bandwidth.
I'm a ham, so I have concerns and I keep my ear tuned that way. But so far all I remember hearing is pilot projects are ending with no deployment.
