1 C-RAN: the Next Big Thing after LTE China Mobile Research Institute

2 2 Agenda China mobiles solution: C-RAN Challenges in mobile internet era Proposals for collaboration with Agilent C-RAN progress

3 3 Challenges in Mobile Internet Era Fast increasing data traffic but slow capacity growth Mobile network capacity will only increase by 10 times Mobile data traffic will increase by 26 times Gap 1 Exabyte = Byte *Source: Cisco VNI Mobile, 2011

4 4 Challenges in Mobile Internet Era 2G 3GLTE Construction Cost ! Inter-cell Interference !

5 5 BS cell site is the major source of power consumption. Challenges in Mobile Internet Era *Source: Base on China Mobile survey on commercial networks

6 6 Agenda China mobiles solution: C-RAN Challenges in mobile internet era Proposals for collaboration with Agilent C-RAN progress

7 7 C-RAN: Road towards green radio access network RRU Virtual BS Pool Optical Network Centralized baseband pool real time Cloud computing Collaborative radio Clean system target

8 8 C-RANCentralized Baseband Pool Traditional macro base-stations Distributed base-stations C-RAN Centralized baseband pool

9 9 C-RANCollaborative Radio interference signal Joint-processingSeparately processing

10 10 C-RANReal-time Cloud Computing TD-LTE TD-SCDMA GSM Traditional baseband equipments Software Defined Radio based on Virtualized Cloud Platform GSM TD-SCDMA TD-LTE App Service

11 11 C-RANClean System Target Power consumption reduced by at most 71% Construction cost per site reduced by 1/3 *Source: Base on China Mobile field trial surveys

12 12 Agenda China mobiles solution: C-RAN Challenges in mobile internet era Proposals for collaboration with Agilent C-RAN progress

13 13 C-RAN Roadmap Centralization Deployment Near Term: Address the fiber resource and management challenge Mid-Term: Address the SDR and Collaborative Radio challenge Long Term: Address the real-time cloud challenge Multi-mode and Collaborative Radio Virtual BTS on real-time Cloud C-RAN Research Data traffic analysis BBU pool research C-RAN Research Data traffic analysis BBU pool research Expend C-RAN to 2G/3G/4G networks Expend C-RAN to 2G/3G/4G networks Drive CoMP research and field trial, pre- commercial product Commercial product development We are here
