29. SkyWeb 3G Optimization: Remote Aggregation Four levels of Optimization: OPEX reduction, conveying E1 signals in superior order signals, as STM-1 20% of Bandwidth gain due to the use of VC-4 STM-1 instead of the CH STM- 1 (from 63 E1 to 78 E1) Aggregation gain due to the partially filled E1 links Overbooking (Hp:VBR from NB) City with RNC RNC SDH transport Network City without RNC STM1 VC-4 NB WLL Backhaul WLL MS SRA4 STM-1 VC-4 SRA4

30. SkyWeb 2G Optimization: Grooming TDM traffic Optimization: Mapping of TDM traffic coming from BTS into CES ATM traffic Once SDT (Structured Data Mode) is enabled, it behaves like a DXC1/0 Aggregation gain due to the partially filled E1 links City with RNC PDH/SDH transport Network City without RNC E1 TDM BTS WLL Backhaul WLL MS SRALXD E1 TDM SRALXD BSC

31. SkyWeb 3G and 2G Optimization: a common network  SkyWeb aggregates CES and Native ATM traffic into common STM-1 VC-4/VC-12 links  An ATM switch is needed for separating TDM from ATM traffic  Forwards traffic respectively to BSC and RNC 1..4x STM-1 MS WLL Backhaul GSM + UMTS BSC E1 ATM E1 TDM ATM Switch RNC NB BTS NBBTS WLL MS
