    SUPER Cell – SK Telecoms’ Network Evolution Vision SUPER Cell – SK Telecoms’ Network Evolution Vision Presentation Transcript

    • SUPER Cell – SK Telecoms’ Network Evolution Vision Changsoon Choi, Ph.D. ICT R&D Division, SK Telecom
    • SK Telecom Changes People’s Life-style Q. What life-style change do we see after LTE has started? A. LTE vs 3G Traffic Breakdown Multimedia Web App Store 33.0% 7.1% )yad/BT007~( Multimedia 3G 39.0% Web App Store 39.4% 5.0% )3102 yaM( 4G/LTE 42.8% )yad/BT043~(
    • LTE/LTE-A Business: Service Milestone SK Telecom has commercialized LTE in 2011, MC and VoLTE in 2012, and LTE-A recently in 2013 LTE Multi-Carrier VoLTE LTE-A 800MHz 800MHz + 1.8GHz Called ‘HD Voice’ Carrier Aggregation 2012.7 2012.8 2013.6 tsriF s’dlroW tsriF s’dlroW ETL revo ecioV :ETLoV 2011.7 tsriF s’aeroK
    • LTE-A Starts with Carrier Aggregation Carrier Aggregation - One of the most distinct technologies in LTE-Advanced - Effective bandwidth expansion through concurrent utilization of radio resources across multiple carriers LTE over Single Carrier LTE-A over Carrier Aggregation 850MHz Carrier 10MHz Bandwidth Max. 75Mbps 850MHz 10MHz 10MHz 1.8GHz 20MHz Effective Bandwidth Max. 150Mbps
    • Key Trends Driving 5G Evolution 1. Rapid Mobile Traffic Growth - Mobile networks have to accommodate exploding traffic growth efficiently and intelligently 1. More Multimedia 65.5PB 2. More Services 53.3 PB SK Telecom’s Mobile Traffic Petabyte/Month (per month) 40.3PB LTE (’11.7.1) 3. Higher Device Spec. 19.2PB D H ll u F 0.4PB 2.2PB 3.5PB ’10.8 ’10.12 ’11.3 5.7PB 7.1PB ’11.6 ’11.9 ’12.9 4. Higher N/W Speed ‘13 ‘14 ‘15 Year
    • Key Trends Driving 5G Evolution 2. Internet of Everything - Mobile networks have to accommodate as many of “connected” devices as they can [2020] MBI :ecruoS ※ [2012]
    • Key Trends Driving 5G Evolution 3. Service Enrichment and Data Explosion - Different services has different requirement in network - Lots of rich services creates “meaningful data” helping to understand user behaviors Generated data 0006 Social Media 0005 VoIP 0004 Enterprise Data 0003 2010 2 1 0 2 k o ol t u O y g ol o n h c e T l a b ol G h c r a e s e R M BI : e c r u o S Large number of rich services Volume in Exabytes (Forecast from IBM) Sensors & Devices 2015
    • Key Trends Driving 5G Evolution Exploding Growth in Traffic Volume Connected Devices Services & Data 5G is a way to go for future network
    • SUPER Cell: Motivation (1) 5G has gained lots of attention for future radio access systems Requirements (presented in 3GPP meeting and other conference) - 100 Gbps maximum cell capacity (1000 times larger than LTE) - 1000 times lower energy consumption 100 G 10 G WLAN 1G 100 M 10 M LTE .11b HSDPA 802.11 WCDMA GSM CDMA 1995 5G .11ad .11n .11g .11a 1M 100 k 2G .11ac LTE Advanced 4G Cellular 3G 1995 2005 2010 2015 Year
    • SUPER Cell: Concept SUPER Cell: SKT’s Future Small Cell Network Architecture - that exploits efficient radio resource utilization, small cell-split, new freq band acquisition 【 SUPER Cell Vision】 Unified RAN Smart Performance Optimized • Mobility/capacity enhanced by control/data separation Energy Efficient Unified • Cloud architecture in heterogeneous network Performance Optimized ) s u o e n e g o r e t e H d n a d u ol C( ) s u o e n e g o r e t e H d n a d u ol C( ) g ni v a S r e w o P( • Dynamic interference coordination and management Energy Efficient Reconfigurable ) n oi t a r e p O e vi t p a d A( t r o p p u S e t a R h gi H t r o p p u S y tili b o M Smart • Green architecture and functions for power saving Reconfigurable • N/W operation mode changes interworking with SON ) g nil u d e h c S y h c r a r ei H(
