Another BPL?
There's an article in today's Washington Post
http://preview.tinyurl.com/6ego68 that describes a technology that's under development to provide Internet access using spectrum in the TV channel range. Apparently this scheme checks for a signal before it uses a specific frequency and switches to a different one if it detects that the frequency is in use. I wonder how this will work and play with amateur radio. I remember when TV channel 2 was established in my home town, effectively shutting down six meter ham operation because the TV signal was so weak that even a correctly-operating six-meter rig would create serious TVI for the fringe reception of channel 2. Decades have passed and this new technology surely is much less sensitive to adjacent signals than the TVs of my childhood, but the analogy persists. 73, Steve KB9X |
