5. Facing Crucial Questions
In these uncertain economic times, there is no room for risky and poorly
analyzed decisions when facing crucial questions, such as:
What will be the best addressable market segment
with a chosen technology characterization?
What will be the effect on the P&L when changing the
CIR in a service bundle?
How will the characterization of the technology
influence the network dimensioning?
What will be the best tradeoff between coverage and
capacity requirements in the network deployment?
How will different types of BS/eNB and UT/UE
devices affect the TCO?
