Limited to 100 seats

First Registered, First Served!

Attendance open to all IWPC Members


The move from traditional macro and small cell architectures to a centralized one in C-RAN and vRAN may be viewed as part of the transition to virtualized networks. This workshop will explore short term opportunities and longer-term potential for more efficient traffic and interference management, optimized applications, services, and content delivery

Workshop Goals

  • Understand network architecture choices and trade-offs
  • Explore network evolution for macro, small cell, DAS, etc. towards 5G
  • Discuss and debate 4G architectural choices towards 5G
