Assume that a network is 1/3 full, and that the traffic in the network doubles
every 30 months. (a) How many months before the network is filled? (b) If
the remainder of the network is deployed with a strategy that is 20% more efficient in using capacity (and the existing traffic is not modified), how many
months before the network is filled? How does this compare to the result from
part (a)?
In Exercises 9.4 through 9.8, assume that the entire spectrum on the links is
shown in the figures (i.e., the spectrum does not extend further to the right).
Guardbands are not explicitly shown in the figures.
