2.1 Generaloverview
SC‐DASplatformisacoveragesystemforin‐buildingservicesdeliveringseamless,highqualityvoice
and dataAsa distributed antennasystem,it provides analoganddigital phone services inmultiple
bandsthroughoneantenna.
Thesystemcoverspublicandprivatevenuessuchas:
z Shoppingmalls
z Hotels
z Campusareas
z Airports
z Clinics
z Subways
z Multi‐usestadiums,conventioncenters,etc.

The system enhances in‐building radio environments that lack signal quality by improving the RSSI
andEc/Io.Byprovidingcommunicationservicesthroughoutthebuilding,thesystemenablesusersto
makeacallsanywhereinthe
coveragearea.
Thesystemusesbothanalog(AMPS)anddigital(TDMA,CDMAandWCDMA)methods.
TheSC‐DASsystemsupportscommunication standardsandpublicinterface protocolsinworldwide
use.
z Frequencies:VHF,UHF,700MHz,800MHz,850MHz900MHz,1900MHz,2100MHz,etc.
z Voiceprotocols:AMPS,TDMA,CDMA,GSM,IDEN,etc.


SC‐DAS comprises frequency specific modules. Coverage for a specific frequency band is
accomplished by inserting a corresponding frequency module into each unit. Because it delivers
multiple signals with one strand of single mode fiber, the system, requires no additional hardware
modificationswheneveranewfrequencyisadded.
Thesystemisfeaturedwiththefollowing:
