In cellular telecommunications, handover, or handoff, is the process of transferring an ongoing call or data session from one channel connected to the core network to another channel. In satellite communications it is the process of transferring satellite control responsibility from one earth station to another … See more American English uses the term handoff, and this is most commonly used within some American organizations such as 3GPP2 and in American originated technologies such as CDMA2000. In British English the … See more In addition to the above classification of inter-cell and intra-cell classification of handovers, they also can be divided into hard and soft handovers: Hard handover Is one in which the channel in the source cell is released and only then the channel in the … See more While theoretically speaking soft handovers are possible in any technology, analog or digital, the cost of implementing them for analog … See more There are occurrences where a handoff is unsuccessful. Much research has been dedicated to this problem. The source of the problem was discovered in the late 1980s. Because frequencies cannot be reused in adjacent cells, when a user moves from one … See more In telecommunications there may be different reasons why a handover might be conducted: • when the phone is moving away from the area covered by one cell and entering the area covered by another cell the call is transferred to the … See more An advantage of the hard handover is that at any moment in time one call uses only one channel. The hard handover event is indeed very short and usually is not perceptible by the user. In the old analog systems it could be heard as a click or a very short beep; in … See more For the practical realisation of handovers in a cellular network each cell is assigned a list of potential target cells, which can be used for handing over calls from this source cell to them. … See more
WebMar 26, 2024 · In these handover testing applications, digital/programmable attenuators act as an interconnect between base stations and create the ability to attenuate each individual path and model the effects of the fading.
