All Rights Reserved2 Effective Positioning of small Cell Small Cell is not a one size fit all solution Best positioned as a complementary solution to the existing tool basket Provides Pinpoint coverage & capacity • Offloads & complements to overall network BrasilBrasilBrasilBrasil WorldWorldWorldWorld Cup FortalezaCup FortalezaCup FortalezaCup Fortaleza StadiumStadiumStadiumStadium Dubai Airport T2Dubai Airport T2Dubai Airport T2Dubai Airport T2 Hotel

All Rights Reserved4 Findings for small venues Interference when large amount of small cells are deployed • High density justifies small cell More interference prone • Interference reduces capacity and coverage of Macro • Not achieving offload Operator objective on deployment of home femto/small cell for small to medium venues to: • Improve voice services • Improve data services • Macro offload Wi-Fi is complementary to small cells • Users prefer Wi-Fi at home for data applications • Voice is majority usage on small cell in home to small venues • Integrated Wi-Fi with auto authentication for seamless experience
    • © 2013 Comba Telecom. All Rights Reserved5 Deployment Case Studies
    • © 2013 Comba Telecom. All Rights Reserved6 GSM Small Cell Deployment Statistics Small Cells have been deployed in different scenarios In public areas, Small Cells are always “on” In private areas, Small Cells are off when people leave
    • © 2013 Comba Telecom. All Rights Reserved7 Overall Deployment Statistics 44% users switch on their small cells when they need, 29% users leave it switched on all day
    • © 2013 Comba Telecom. All Rights Reserved8 Small Venues With High User Density Effective solution: home/enterprise small cell • Carry voice traffic over GSM, interference is well managed by carrier assignment • Intelligent offload of data traffic over Wi-Fi with carrier grade QoS, management and seamless user experience • Low power, friendly looking, plug-and-play with SON Scenario • Voice and data driven small hotspots • More than 200 mobile users during the peak hour • Poor indoor mobile signal coverage
    • © 2013 Comba Telecom. All Rights Reserved9 Small Venues With High User Density Deploying GSM Small Cell results in… • Signal coverage significantly improved • Mobile devices transmit less uplink output power is reduced: longer battery life, more environmental friendly • Cost effective solution utilizing existing broadband connection as backhaul for small cell Small Cell Coverage Comparison Before After RxLvl Coverage rate>-85dBm RxQual (Lvl 1~3) 31.20% 13.70% 100% 98.80% 0.00% 20.00% 40.00% 60.00% 80.00% 100.00% Rxlev ratio (>-85dBm) RxQual ratio(0-3) Before After

All Rights Reserved10 Campus Hotspots Scenario • High density environment where there is many concurrent users running most data “hungry” applications • Traffic peak at class break and night time • Utility ratio of Macrocell can be over 120% at busy time • Ubiquitous Wi-Fi also needed in most public areas Enterprise Small Cell: an effective way for offloading • Deploy Enterprise Small Cells in public venues to offload the high voice traffic at peak hours • Offload data traffic to secured Wi-Fi network with seamless authentication and roaming support Comba Small Cells deployed in Guangdong, China

    • © 2013 Comba Telecom. All Rights Reserved12 High-rise Apartment Buildings Scenario • Poor user experience in voice calls caused by Overlapping coverage of densely deployed outdoor Macrocells Ping-Pong effect happened in handover • Majority data traffic will be carried over privately owned Wi-Fi Perfect fix: Home Small Cell with Wi-Fi in one-box solution • “Leading” small cell signal solves interference & ping- pong effect • Offering customized and add-on services makes the “small box” more valuable
