Terminology
•UniversalbandsrefertoRADWINUniversalbands.
•3.Xor3.XGHzreferstothefrequencyrange3.3–3.8GHz
•BRSreferstothe2.5GHzbandsubjecttothe FCCBRSregulations
• A3.XODUisanODUpreconfiguredtooperateinthe3.XGHzlicensedbands
• A3.XLinkinaRADWIN2000linkusingapairof3.XODUs
•HighResolutionBands‐Channelminimumstepis250KHz.appliesto3.475‐3.650GHz
IC,3.4‐3.7GHzETSIandthe3.3‐3.8GHzUniversalband.
•LowResolutionBands‐Channelminimumstepis1MHz.AppliestoFCCregulationsin
the3.650‐3.675GHzband.
• Inthefield,alinktypicallyhasalocalorheadquarterssite.Typically,aserviceprovider
isthelocalorheadquarterssite.Theservicerecipientistheremotesite.
Wherethelinkiscompletelyinternaltoacorporation,thechoiceofthelocaland
remoteisjustamatterofconvenience.
Alinkthen,consistsoftwosites.
• InBroadbandWirelessterminology,thelocalandremotesitesaresometimesreferred
toas“near”and“far”,“HQ”and“remote”andsoon.
TheRADWIN2000CPlusclassradiosachievetheir250Mbpsthroughputbydrawingon
newtechnologydevelopedfortheRADWIN5000PointtoMultipointseries.Therefore
thesitesarenotsymmetrical.Thelocalsitereferredtoearlier,usesabasestationradio
(HBS)asthelinkMasterODUandtheremotesiteusesasubscriberunit(HSU)asthe
linkSlaveODU.
TheHBS/HSUandmaster/ slaveterminologywillbeusedthroughoutthemanualboth
todescribethetwolinksiteswithoutfurthercomment.
• ThelinkisnormallyconfiguredandmanagedusingaPC,themanagingcomputercon‐
nectedtotheMasterODU.(Thepreciserequirementsforthemanagingcomputerare
setoutonpage 4‐1).ItmayalsobeconnectedtotheSlaveODUeitherdirectlyorover ‐
the‐air.
Wewilloccasionallyneedtodistinguishbetweenthesitetowhichthemanaging
computerisconnected,andthesecondsite,whentheyarenotspecificallyMasterODU
orSlaveODU.Theformerwillbecalledthemanagingsiteandthelatter,theover‐the‐
airsite.Whichiswhich,isalwa ysdeterminedbythelocationofthemanaging
computer.
• RADWIN2000CPlussupportsthreeconnectionmethodsforthemanagingcomputer:
•Local‐adirectpeertopeerconnectionbetweentheEthernetportsonthemanaging
computerandthePoEdevice.
•Network‐themanagingcomputerandthesiteAIDUorPoEdevicebelongtoaLAN
andcommunicatethrougharouterorswitch
•Over‐the‐air‐themanagingcomputerconnectstositeBviatheairinterface
• ThemanagingcomputerisconnectedtothelinkthroughaPoEdevice.
