Why Change The RAN?
 HetNet Deployments are picking up but not without
challenges
Cost and complexity of
network planning
When it comes to capacity management,
redirection alone is not sufficient
C-RAN promises improved network efficiency, with lowered TCO,
to improve monetization of mobile broadband
