SK Telecom Femtocell Cost Efficiency ‘Cost per Megabyte’ and ‘Quality Enhancement’[ $,USD ] [ Throughput ] 10 60 Site#1 Macro Femtocell (+WiFi) Site#2 5 Site#3 40 Site#4 Site#5 0 Site#6 20 WiFi Site Site#7 Easy to Hard to Connect Site#8 Except Connect Backhaul Include Backhaul Cost Site#9 Cost 0 Macro Femto
  • 3. SK Telecom Femtocell Tech. Initiative (1) X2 Handover between Femto and Macro ■ SKT’s proprietary X2 H/O through Gateway  Test Results EPC FGW S1 X2 X2 Femto Zone Macro Zone Performance during Handover HO Type Throughput VoLTE MOS S1 16.9 3.74 X2 20.1 3.83
  • 4. SK Telecom Femtocell Tech. Initiative (2) Coverage Extension Solution ■ Multi Femtocells ■ Single Femto DU & Multi RUs Femto#1 Femto#2 FRS#1 Femto#3 Femto#4 HO Type Throughput VoLTE MOS HO Type Throughput VoLTE MOS X2 20.1 3.83 No H/O 27.1 4.45 ※ FRS : Femto Remote System
  • 5. SK Telecom Femtocell Tech. Initiative (3) Femto Interference Coordination System■ Periodic network listening  Test Results → Fine power control based on CQI statistics - Throughput increased by 50% after FICS On Throughput from Femtocell UEs ICS OFF ICS ON → Rapid power adjustment based on abrupt Femtocell’s UL interference level to protect macro UE’s QoS Time * Checked per 10 seconds ※ Macro - Femto ICS Test Scenario eNB → HeNB Edge → eNB FICS Interference Data eNB HeNB GW HeNB HeNB Gathering MUE HeNB Interference Control eNB MUE FUE MUE
