M-­‐CORD  Drivers:  Operator  Challenges      

State  of  the  infrastructure:  Built  with  closed  proprietary  boxes    

•  Inefficient  uJlizaJon  including  sub-­‐opJmal  use  of  precious  radio  resources  •  Inability  to  customize  for  various  customers  •  Slow  in  creaJng  innovaJve  services      •  Cannot  support  industry-­‐specific  IoT  scenarios    

Mobile  infrastructure  needs  re-­‐architecJng    –  To  Enable  5G      

ü  Agile  and  cost-­‐efficient  deployment  

M-­‐CORD  ObjecJves  

ü  Provide  customized  services  and  be8er  QoE  to  customers    

ü  Enhance  resource  uJlizaJon,  especially  spectrum  

•  On-­‐demand  deployment  •  Virtualized  /disaggregated  RAN  and  EPC  •  Commodity  H/W  and  open  source  

•  Customized  service  composiJon  •  Reduced  latency  and  increased  throughput  •  DifferenJated  QoE  based  on  service  requirements
