ExtCell

simple module

The ExtCell module represents a fictitious cell that is used to model interference from neighboring cells, without actually instantiating them completely (i.e., without having actual UEs producing actual traffic). It can be configured with physical layer parameters (such as transmission power and direction) and the amount of resource occupation. This module can be replaced by BackgroundCell modules, which provide more flexibility.
