HubSiteSynchronization
WhatisHubSiteSynchronization(HSS)
Whenseveralradiosarecollocatedatacommonhubsite,interferencemayoccurfromone
unittoanother.RADWINODUssupportthecollocationofmorethantwounitsatacentral
site.LikeanyotherRFdeployment,thewirelessoperationishighlydependentonfactors
suchasavailablefrequencies,thephysicalspacingbetweenradios,otherthirdparty
interferingradios,andwhetherotherRADWINradiosareinstalled.
RADWINHSS
TheRADWINHSSmethodusescarriespulsessenttoeachODU,whichsynchronizetheir
transmissionwitheachother.Thepulsesynchronizationensuresthattransmissionoccursat
thesametimeforallcollocatedunits.Thisalsoresultsinallofthehubsiteunitsreceiving
dataatthesametime,eliminatingthepossibilityofinterferencethatcouldresultifsome
unitstransmitwhileotherunitsatthesamelocationreceive.
Figure 13‐1illustratesinterferencecausedbynon‐synchronizedcollocatedunits.
Note
HSSdoesnoteliminatetheneedforcarefulRFplanningtoensurethe
designwillworkasplanned.SeeSiteSurveyforinformationoninstallation
