Question: In the WVG Compact Coordinate System for SMS, what is a key characteristic of Absolute Coordinates compared to Relative Coordinates?
Option 1: Absolute Coordinates can be negative, while Relative Coordinates are always positive.
Option 2: Absolute Coordinates are always positive and represent grid line numbers, whereas Relative Coordinates can be positive or negative.
Option 3: Both Absolute and Relative Coordinates must be used within the bounds of the local envelope.
Option 4: Absolute Coordinates are signed (can be positive or negative), unlike unsigned Relative Coordinates.
Explanation: This question assesses understanding of coordinate systems in telecom messaging, specifically highlighting the distinction between absolute and relative coordinates. Absolute Coordinates are always positive and directly represent grid line numbers. In contrast, Relative Coordinates can have both positive and negative values, indicating direction from a reference point.
