TBS
TBS(transportationbasestation)radiosareOFDM/MIMO3x3,IP‐67compliantoutdoorunits
placedatfixedlocationsalongthewaysideandcommunicatewithTMUs(Transportation
MobileUnits)installedonboardtrains/metrossoastoensureconsistentandreliable
broadbandradiocoverage.
EachTBSisconnectedtoanEthernetswitch,whichisconnectedinturntothewiredbackhaul
network.TheTBSsaresynchronizedtoacommontimebasetoavoidpotentialmutualradio
interferencesandallowfasthandover.
TBSantennas
Althoughtherearemanydifferenttypesofantennas(seeAppendixA,AntennaGuidelinesfor
alistofantennas),werecommendusingflatdualpolarizationandsinglepolarization
antennaspereachdirection.Thisallowsatotalof6RFchainstobeconnected,while
minimizingthenumberofantennas.

Synchronization Introduction
PoE
Power‐over‐Ethernetdevicescanbeusedtosupplybothpowerandnetwork
communicationstotheTBS,TMU,andtheOSU/ISU/GSUs.RADWINprovidesdifferenttypes
ofAC/DCPoEinjectorsinseveralpowerranges.
IfM12cablingmustbeusedonboard,aspecialPoE‐TMUcableisavailablefromRADWIN.
AlternativelyRADWINTBS/TMU/OSUcanbeconnecteddirectlytoastandard802.3at(PoE+)
device.ItisalwaysadvisedtoconsultwithRADWINprofessionalservicesforthebestpower
solutionforyourproject.
1.2.3Synchronization
•TheTBS'snetworkissynchronizedeitherviaGPS‐basedsystem(forabovegroundsce‐
narios)orviaEthernet‐basedsynchronization(foraboveorundergroundscenarios).
•ForGPSbasedsynchronization,theTBS’sintegratedGPSSynchronizationUnitisused.If
thisisnotpossible,theGSUcanbeused.
•Ethernet‐basedsynchronizationrunsoverthesamedatabackhaulnetwork.Theimple‐
mentationofthesynchronizationprotocolisviaanIndoorSynchronizationUnit(ISU)or
OutdoorSynchronizationUnit(OSU)thatisconnectedtooneofthenetworkswitches,
andprovidesthemasterclocktoallTBSsinthenetwork.
•OSUisafullyoutdoorunit1withanembeddedGPSantennaaswellasanexternal
GPSantennaport(tobeusedifanexternalGPSantennaisneeded),andcancon‐
necttothenetworkviafiberoptic.
•TheOSUandISUworkinthesamemanner,withoneimportantdifference:The
OSUcanreceiveaGPSsignalasthesynchronizationsource.
•UsingmultipleOSUsenablessynchronizationofaringtopology,eachOSUsynchro‐
nizingasectionofthering.
•Redundantsynchronizationunitsensurehigherresiliencyofthesolution.
•Withamixedtunnel/outdoorline,anOSUistypicallyusedinsidethetunnels,and

Chapter2:SiteInstallation
2.1ScopeofThisChapter
ThischapterdescribeshowtoinstalltheequipmentfortheTransportationFiberinMotion
solution.Itisdividedintotwomainsections:
•Waysideinstallation
•On‐boardinstallation
2.2Wayside
TheFiberinMotionsolutionusesmultipleantennastoenableMIMOandDiversitymodes.
Thesolutionreliesonantennaspacing,aswellasdualpolarization/dualslantedantennasto
differentiatetheradiostreams.
2.2.1Overview
GeneralMountingArrangement
TheTBSunitmustbeinstalledinaRestrictedAccessLocation.
TheTBScanbemountedonapoleorawall,togetherwithitsantennasandLPUs.Toenable
betterMIMOconditions,theantennasshouldbedividedbetweenverticalandhorizontal
polarizations.Figure 2‐1showsanexampleofaTBSmountedonapole
•Placethetower/TBSatthelocationdeterminedbythesitesurvey.
•Makesurethereissufficientline‐of‐sighttowardsthetracksegmenttheantennas
willcover
•Makesurethattherearenoobstaclesdirectlyinfrontoftheantennas
•Thelowestantennamustbehigherthanthehighestrailcarontheline
•ThereareseveralwaysyoucanorienttheTBSantennas,dependingontheorien‐
tationoftheTMUantennas.TheseoptionsaredetailedinseeTMU‐TBSantenna

•UsethePoEtosupplypowertotheTBS
•UsethePoEortheSFPfiberconnectiontoprovideaLANconnectiontotheTBS.
•InstalltwoLightningProtectionUnits(LPU):OneclosetotheTBS,andtheother
closetothePoE.
