2.1 Purpose
Alliance_N20isacoveragesystemforin‐buildingservicesdeliveringvoiceanddatainhighqualityand
forseamlessly.
Asadistributedantennasystem,itprovidesanaloganddigitalphonesystemsthatareservedinmultiple
bandsthroughoneantenna.
Thesystemcoversgeneralpublicinstitutionsandprivatefacilities.
 Shopping
malls
 Hotels
 Campusareas
 Airports
 Clinics
 Subways
 Multi‐usestadiums,conventioncenters,etc.

Thesystemhelpsimprovein‐buildingradioenvironmentsinpoorconditionand  makebetterpoorRSSI
andEc/Io.Byprovidingcommunicationservicesateverycornerofbuildings,thesystemenablesusers
to
makeacallatanysiteofbuildings.
Thesystemusesbothanalog(AMPS)anddigital(TDMA,CDMAandWCDMA)methods.
The SMDR‐NH124 system supports communication standards and public interface protocols in
worldwideuse.
 Frequencies: VHF,UHF, 700MHz , 700MHz_MIMO , 850MHz , 1900MHz , 2100MHz ,
2100MHz_MIMOetc.

 Voiceprotocols:AMPS,TDMA,CDMA,GSM,IDEN,etc.
 Dataprotocols:EDGE,GPRS,WCDMA,CDMA2000,Paging,LTEetc.

Alliance_N20isinmodularstructureperfrequency.To providedesiredfrequencyinabuilding,allyou
needtodois toinsertacorrespondingfrequencymoduleintoeach unit. Asitdeliversmultiplesignals
with one optical cable,
the system, in one‐body type, does not require additional facilities whenever
newfrequencyisadded.
Thesystemisfeaturedwiththefollowing:
 Flexibiltiy&Scalabiltiy
 Supportfiber‐opticportsupto39
 Clusteringmultiple‐buildings(campus)asonecoverage
  Modularstructures
 Modularfrequencyupgrade
  Plug‐intypemodule
