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

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”.

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

Is there any active DAS system become passive SISO complementary in IBS co-construction to resolve 4G issues? Yes! Wave-In SDAS solution

In-Building Dilemma for FDD LTE • Traditional design using passive SISO for in-building construction; however there

• 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 2016 3CA 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)
