Does anybody know what kind of considerations are given to the frequencies used in FM, that is the freq's used to represent the user data. For simplicity sake, using a two-level FM model for modulating binary data, a "0" is represented by no modulation of the carrier, and a "1" is represented by changing the frequency.
1)Is the new frequency being used allocated as part of the standard?
2)How high above (or below) the carrier is it usually?
3)Is there a possibility of intereference with another signal that is transmitting using the same FM modulating freq of one system.
Sorry if this is worded confusing.
