2 Meaning of Distributed Concept Basic concept of distributed antenna system believes through many lower power distributed antenna in a area can provide better system performance (opportunities gain) than one big power antenna

3 Slim DAS and Fiber Repeater Difference Fiber Repeater and Slim DAS are different: Repeater is a 2G/3G legacy product emphasize on UL gain to extend coverage. SDAS is a new design product emphasize on delivering many DL low power with 16QAM/64QAM coverage to different area providing better LTE performance. Design concept difference Fiber repeater use digital approach in order to get higher gain DAS use analog approach in order to distribute energy and control noise figure, reduce the cost. SNR=32 Signal SDAS SNR=28 SNR=28 SNR=28 SNR=28 SNR=32 SNR=18 Repeater Signal repeat point SNR=0 Noise SNR=0 Distance Noise Distance Linear & Distributed SNR=15 - SNR=0 1 st Gained Noise Noise

4 In-Building Dilemma for TDD LTE Traditional design using passive SISO for in-building construction; however there exists many controversy when 4G coming LTE introduce MIMO In order to achieve MIMO performance, many co-construction field introduced passive MIMO which double the cost of POI Coaxial cable Installation LTE introduce TDD By indoor planning textbook, indoor coverage design logic need to separate TDD and FDD for indoor DAS Band 7 band 38 coexist issue Band 1 band 40 coexist issue Is there any active DAS system become passive SISO complementary in IBS coconstruction to resolve 4G issues? Yes! Wave-In SDAS solution

5 In-Building Dilemma for FDD LTE Traditional design using passive SISO for in-building construction; however there exists many controversy when 4G coming LTE introduce MIMO In order to achieve MIMO performance, many co-construction field introduced passive MIMO which double the cost of POI, Coaxial cable, Installation etc. If co-construction field still use passive SISO which cannot emphasis LTE benefit (that s the reason some carrier use HSPA to compete with LTE since at indoor SISO environment, not much performance delta between HSPA and LTE) LTE-A introduce Carrier Aggregation CA is a key feature in LTE roadmap to support higher Tput, currently majority of LTE smartphone support 2CA and after CA LTE smartphone become mainstream ==> how to find a cost-effective way for in-building solution can first support MIMO then easily upgrade to 2CA and 3 CA become operator key concern? Now is time to re-think about co-construction strategy, how to emphasis every system performance with cost effective way ==> under the contain of performance and cost, passive SISO definitely not a optimal way==> its time to change the evaluation method from how antenna port to KPI (cost/m^2/mbps) Is there any active DAS system become passive SISO complementary in IBS coconstruction to resolve 4G issues? Yes! Wave-In SDAS solution
