Whenseveralradiounitsareco‐locatedatacommonsite,interferencemayoccurfromone
unittoanother.Thisinterference,ifitoccurs,happenswhenatagivenmomentintimeone
unitistransmitting,buttheotherisreceiving:thereceivingunitmaydetectthetransmitting
signalsofitsimmediateneighborinsteadof(orinadditionto)signalsfromwhereitshould.
Figure 9‐1illustratesinterferencecausedbynon‐synchronizedco‐locatedunits:IfUnit1is
receivingatagivenmomentfromUnit1A,andatthatsamemomentUnit2istransmittingto
