IntheBandarea,dothefollowing:
• Sel
ecttheProtocolmode:ThisconfiguresthesystemtosupportWiMAXradiosthatare
oneofthefollowing:
MIMO(m
ultiplein‐multipleout)
SISO(single
in‐singleout).Thedefaultis“MIMO”.
• Select
theCenterFrequencyandBandwidthusingthearrowsnexttothefields.Thecenter
frequencyisthefrequencyofWiMAXradiosbeingusedforBand1andBand2.
NOTE: InMIMO mode,thefrequenciesarethesame.Thesystemcanbeconfiguredtosupport2‐SISO
radios,oneperband,acrossany30MHzwithintheWiMAXband.
• Usethepull‐downtoselecttheSwitchingMode.Thisindicateswhetherornotthe
downlink‐to‐uplinkframedurationisknown.Thetwooptionsareasfollows:
– Stat
ic‐Selected:Thismodespecifiesthenumberofsymbols.Usethepull‐downto
selectthesymbolinthedownlinkanduplinkportionsoftheframe.(Thedefaultis
“29,18”.)Inthismode,thesystemalwaysswitchesfromthedownlinktotheuplink
pathafterthedownlinkportionoftheframehaselapsed.
– Stat
ic‐Auto:Thismodecausesthesystemtoattempttodeterminethecorrect
switchingtime,thenenforceit.(Thedefaultis“Static‐Auto”)
• SelecttheBandSynchronizationModewiththep
ull‐down.Thisparametercanbe
configuredtooperateasoneofthefollowing:
– Synchronized:ThismodeisforcaseslikeMI
MO,wherethetimingforbothbandsis
thesame.Inthismode,thesystemalwaysswitchesbetweenuplinkanddownlink
simultaneouslyforbothbands.
– Unsynchronized:
Inthismode,thetwoWiMAXbandsswitchindependentlyfrom
eachother.(Thedefaultis“Unsynchronized”)
• Reference
:SelectwhichWiMAXradiobandwillbeusedforframereference.
• Wh
enanybandisnotconfigured,usetheShutdowncheckbox.Thesystemignoresany
alarmsgeneratedfromtheshutdownbands.
• Us
ethepull‐downtospecifytheUplinkandDownlinkgainforeachband.Youcanset
systemgainwithinthespecifiedrangein1dBincrements.
• Use
thepull‐downtosettheUplinkAutomaticLevelControltoeither“Single”or
“Multiple”foreachbandinthesystem.(Thedefaultis“Multiple.”)
