Lastly, one can use this additional gain to accommodate the use of less costly components for cost
reduction reasons. We must add this last option is not the typical application used in the cellular
environment.
In any case, an interactive design process is required that interfaces the link budget variables to the
link budget simulation to the network level simulations.
