Whats the difference between wide and narrow bands and when should I use them?
The advantage of narrow band channels is that they take up less RF spectrum and thus more channels can be used in a given area. The disadvantage of narrow band channels is that they have more noise and the frequency response is not as good compared to wide band channels. Here’s a rule of thumb: use narrow band channels when you’re trying to get as many channels into a given area (such as schools) to minimize interference, and use wide band channels everywhere else.
