Kevin McDougald from Winnipeg, Canada writes: There is another factor to consider in allowing the space between TV channels to be used for wireless communications.
Signals in the VHF band, including channels 2 to 13 and FM radio stations, are usually line of sight: they go off toward the horizon and then off into space beyond that.
Usually, but not always. Sometimes the atmosphere acts up and strange things start happening.
I used to have a second TV set that wasn't hooked up to cable. Occasionally, the usually empty channel 11 would be suddenly occupied by a station coming in from 165 miles away in North Dakota.
In an even stranger incident, I tuned in to a newscast from Nashville on the normally empty channel 5. At the same time, a station from Tulsa, Oklahoma was coming in on channel 2. Again, the atmosphere was acting up.
Most people won't notice these oddities when they happen to TV stations. But could there be problems when, all of a sudden, a wireless signal from Nashville is coming through nice and strong in Canada?- Posted 22/05/08 at 6:19 PM EDT | Alert an Editor | Link to Comment
