A singe cell consists of several MSs connected to their serving BS. The reference cell is a single cell that is surrounded by two tiers of virtual cells to form a 19 cells (or 57 cells for tri-sector deployment) cluster. This cells clutter is then populated with a certain number of MSs. The reference cell is by default at the center of the network, but you can modify it by selecting any cells you want. Part of configuring a CDMA or OFDMA network is selecting the reference cell. In SEAMCAT it is possible to choose between two network configurations (3GPP and 3GPP2, see Figure 176).

The reference cell in Figure 183 180 is used to calculate the effects of interference and to measure results and all non reference cells are used to provide a proper interference background to the reference cell.  You can click on the cell that should be used as reference cell when gathering results. The red cell is the current selection.

Center of infinite network


-

Boolean

-

Quick access to predefined selection of reference cell. This only changes the selected reference cell – no other simulation parameter is changed.

Left hand side of network

-

Boolean

-

Position the reference cell on the left hand side of the network. Can be used to reproduce border network layout.

Right hand side of network

-

Boolean

-

Position the reference cell on the right hand side of the network. Can be used to reproduce border network layout.
