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
