- When the Correlated distance option is checked, it means that the positions of the receiver and transmitter are geographically fixed with respect to each other (e.g. co-located or constantly spaced base stations). The transmitter is considered a reference centre.
- When the correlated distance is unchecked, it means that the receiver is randomly moving around the transmitterYou have 2 primary options to define type of mutual placement of VLR with respect to VLT:
See ANNEX 12: for further details on the algorithm and conventions.

Description | Symbol | Type | Unit | Comments |
Correlation distance | - | B | - | When checked, the only the Delta X and Y are editable. |
Delta X | X | D | Km | Horizontal distance between the transmitter and receiver. It can be used to shift horizontally the distributed receivers. |
Delta Y | Y | D | Km | Vertical distance between the transmitter and receiver. It can be used to shift vertically the distributed receivers. |
Path azimuth | - | D | Degree | Horizontal angle for the location of the Rx respect to the Tx. If constant, the Rx’s location will be on a straight line. If not, the location of the Rx will be on an angular area. (See Annex A12.3) |
Path distance factor | - | D | - | Distance factor to describe path length between the Tx and the Rx. If the path factor is constant, the Rx will be located on a circle around the Tx. (See Annex A12.2) |
Use of polygon | - | B | - | When this is checked, you can select other shape of deployement than the default circle |
Shape of the polygon | - | B | - | You can select between hexagon (6 sides), heptagon (7 sides), Octagon (8 sides), Pentagon (5 sides), Rectangle (4 sides) and Triangle (3 sides) |
Turn CCW | - | D | degree | Allows to rotate counter clock wise the selected polygon |
