    WCDMA 2100 F3 I Background

    Traffic data growth is increase significantly. Telkomsel base case

    forecasts data traffic to increase to 1,800 PB in 2022 (from business

    planning). 3G traffic on mobile networks for Telkomsel is doubling

    every year, putting pressure on network capacity

    Data Payload share of 3G is dominated nearly 70% of total national

    payload. Existing 3G spectrum is not enough to carried projected

    traffic data.

    High power utilization in some 3G sites/cells

    High number of HSDPA user in some cells. Higher number of

    HSDPA user in cell will lead to lower HSDPA throughput per user.

    Implementation of existing both carrier HSDPA (F1 & F2) will reduce R99 quality, especially R99 Voice. In close time, there will be more

    offload from 2G to 3G and its not only data traffic but also voice traffic

    WCDMA 2100 F3 I Objective

    Deliver high quality of broadband service

    Maintain / improve deliverable HSDPA throughput along with highly

    projected data traffic growth

    To avoid EcNo degradation that could lead to shrinking coverage,

    ping pong 2G-3G handover, RAB drop.

    To avoid high PA utilization and excessive usage of PA per carrier

    To improved voice call quality by having dedicated R99 carrier

    WCDMA F3 Planning Guideline I F3 for Coverage, Capacity & Quality

    F 1

    DL/UL load/interference

    HSDPA consume PA TX power 4 ~ 10 W, causing : - EcNo & EbNo (interference) degradation - Bad voice quality - Limited HSDPA throughput - Shrinking coverage - High PA utilization

    Lesser interference

    Better voice quality Better CPICH EcNo Enlarging coverage/ minimize shrinking coverage, minimize ping pong 2G ~ 3G with all its problems Better Traffic EbNo Improve voice quality

    Higher possibility to increase the CPICH TX power to improve indoor penetration

    HSDPA

    R99

    Control

    More PA power for HSPA Higher HSPA throughput Lesser interference better CPICH EcNo enlarge coverage

    3rd Carrier deliver solution of enlarging coverage, minimize shrinking coverage, minimize ISHO to 2G,

    improving voice quality, improving HSDPA throughput, reducing PA utilization

    When there is HSDPA

    Traffic, signal quality is

    degraded (EcNo ~ -12) and

    impact the quality for all

    other services

    When there is no HSDPA

    Traffic, signal quality is

    excellent (EcNo ~ -4)

    WCDMA 2100 F3 I HSDPA causes Signal Quality Degradation

    WCDMA F3 Planning Guideline I Deployment Strategy

    Deployment Strategy

    Third Carried is preferred to be implemented in Micro Cluster inside BBC area that is

    defined as high demand data traffic.

    Third Carrier is implemented on top of Dual Carrier Site in clustered hotspot area to

    ensure smooth mobility

    Third Carrier is used as HSDPA service layer.

    Main Road

    Residential

    1 Carrier Site (F1) 2 Carrier Site (F1 & F2) 3 Carrier Site (F1, F2 & F3)

    Better mobility

    Capacity based Cluster based

    (in DATI II border)

    110 DATI II need

    clusterized

    Site need F3

    Site no need F3

    WCDMA F3 Planning Guideline I WCDMA F3 Site Criteria

    Site configuration :

    - Site with dual carrier and HS on both carrier

    - IP transport (Metro-E, IP Microwave) or ATM with minimum 8 E1 (urgently recommended to convert to IP

    transport)

    Site Criteria (OR) :

    Average total PA utilization > 70%

    Average total PA utilization for non HS > 60%

    Average HSDPA user per cell carrier > 16 (in BBC tier 1)

    RTWP > -95 dBm (in busy hour)

    Average daily payload per Cell Carrier > 3 GB

    More recommended to activate also in surrounding for smooth mobility purpose

    Recommended area (AND) :

    Micro cluster areas : residential, commercial, government, campus/school

    1. 3rd Carrier Cluster had been implemented in cluster of 10 sites in Lampung

    area (27 Jun 2013)

    2. Main KPI performance is improved for KPI accessibility & retainability (Voice,

    PS & HSDPA)

    3. KPI performance in mobility is maintain (SHO & ISHO).

    4. KPI performance in mobility (IFHO) is degrade

    5. CS Traffic, HSUPA traffic and HSDPA traffic is trend to increase
