PRODUCTOVERVIEW
InterReachSpectrumsupportsupto8bandsinasinglesystem.Eachantennalocationsupports
thosebandsinmodular,grouppairings.EachlocationincludesaMainRemoteAccessUnit
(MRAU)thatcanpoweruptothreeadditionalSecondaryRAUs(SRAUs),eachofwhichsupport
twopoweramplifierpairsforatotalofeightamplifiers.MRAUsandSRAUsaregroupedlogically
basedoncommonserviceprovidergroupingsandinclude:850/1900,700/700MIMO,800/900
SMR,700SISO/AWS,and800/AWS.AddingfrequencyisassimpleasplugginginanSRAUtothe
existingMRAU(see
Table4onpage19throughTable6onpage21in“AppendixA:
Specifications”).
RAUsareavailableintwodifferentoutputpoweroptions:StandardandHighPower.Thesecan
be“mixedandmatched”onasystemtomeetthespecificneedsofavenue.
SinceSpectrumcanbeconfiguredtosupportasmanyasfourcascadedrunsofsixteentotal
ExpansionModuleGroups,thesystemconfigurationpossibilitiesareseeminglyendlessandcan
scaletosinglesystemsthatincludeasmanyas128MRAUlocations,witheachofthoselocations
supportingbetweenoneandeightRFbands.Andeachofthosebandlocationsoffers26dBm
(P1dB)or31dBm(P1dB)ofoutputpowerbasedonselectingstandardorHighPower(HP)RAUs.
ThesystemmaybescaledtoaddnewbandsorRAUlocationsitesas‐neededandoffersgreat
serviceflexibilityandperformancerelativetoshared,wide‐bandamplifiersystems.Eachservice
providermaycontroltheirbandofinterestandenjoythepredictabilityinconsistentserviceat
eachRAUlocationindependentofwhatotheroperatorsaredoingorthelengththesignaltravels

TheRAUsaretypicallymountedaboveceilingtilesorinout‐of‐sightlocationsascloseaspossible
