Difference Between Handoff Vs Handover in Tabular Form

handoff refers to the process of transferring an active call or data session from one cell in a cellular network to another or from one channel in a cell to another

A handover is a process in telecommunications and mobile communications in which a connected cellular call or a data session is transferred from one cell site (base station) to another without disconnecting the session.

Three types of handoff are:
1.) NCHO
2.) MCHO
3.) MAHO
Three types of handoff are:
1.) Soft handover
2.) Hard handover
3.) Softer handover
In NCHO (network controlled handoff), the network makes the decision. It is used in AMPS.In hard handover (break before make) the mobile connects only to a single base station at a time.
In MCHO(Mobile controlled handoff), the mobile decides for itself:
(a) Forward: the mobile initiates Handoff and sends the request to the new AP.
(b) Backward: the mobile initiates Handoff and sends the request to the old AP.
In soft handover (make before break) the mobile receives from and transmits to multiple base stations simultaneously.
In MAHO (mobile assisted handoff), the mobile provides data for network to make the decision. It is used in GSM and IS-95 CDMA.Softer handover is a situation where one base station receives two user signals from two adjacent sectors it serves through multipath propagation.
Handoff is the process that occurs when a mobile is “handed over” from one access point to another, i.e., the access point which the mobile is using changes.Handover is the transference of authority, control, power or knowledge from one base station to another.
