Operationissubjecttothefollowingtwoconditions:(1)thisdevicemaynotcauseinterference,and(2)this
devicemustacceptanyinterference,includinginterferencethatmaycauseundesiredoperationofthedevice.
Toreducepotentialradiointerferencetootherusers,theantennatypeanditsgainshouldbesochosenthatthe
equivalentisotropicallyradiatedpower(e.i.r.p.)isnotmorethanthatpermittedforsuccessfulcommunication.
Thisdevicehasbeendesignedtooperatewiththeantenna(s)listedbelow,andhavingamaximumgainof2.0

ICRSS‐210A9.4(4)states:Thedeviceshallautomaticallydiscontinuetransmissionincaseofabsenceof
informationtotransmit,oroperationalfailure.Adescriptionofhowthisisdoneshallaccompanythe
applicationforequipmentcertification.Notethatthisisnotintendedtoprohibittransmissionofcontrolor

DescriptiontomeetICRSS‐210A9.4(4):
Datatransmissionisalwaysinitiatedbysoftware,whichisthenpasseddownthroughtheMAC,throughthe
digitalandanalogbaseband,andfinallytotheRFtransceiver.Severalspecialpackets(ACKs,CTS,PSPoll,etc)are
initiatedbytheMAC.ThesearetheonlywaysthedigitalbasebandportionwillturnontheRFtransmitter,
whichitthenturnsoffattheendofthepacket.Therefore,thetransmitterwillbeononlywhileoneofthe
aforementionedpacketsarebeingtransmitted.
