Soft Handoff has been shown to perform better than hard handoff in aspects like reverse link capacity and cell coverage. However, some reported comparisons include distance criteria leading to rather pessimistic performance for hard handover. This paper presents a model based exclusively on power criteria that allows a gradual and continuos transition between soft and hard handoff operation. Furthermore, in order to contrast macrodiversity benefits, some repercussions and limitations macrodiversity imposes on system design are addressed. Supporting of MRC and EGC combining techniques on the reverse link is also taken into account.
