In the GXM, Hop Freq Offset allows the user to select an offset of 115.2 KHz, or 230.4 KHz higher than 
the standard frequency selection. For example, if two networks are operating side by side, with one set to 
Hop Freq Offset of 0 and the other to Frequency Offset of 1, the frequencies used in the different hopping 
patterns will be offset by 115.2 KHz.
