Abstract

The popularity of wireless communication is increasing quite rapidly throughout the world after the introduction of cellular and broadband technologies. The real potential of broadband wireless networks lies with mobility .Mobility is the most important feature of a wireless cellular communication system. Usually, continuous service is achieved by supporting handoff (or handover) from one cell to another. Handoff is the process of changing the channel (frequency, time slot spreading code, or combination of them) associated with the current connection while a call is in progress. It is often initiated either by crossing a cell boundary or by deterioration in quality of the signal in the current channel. This paper is a review on the handoff issues that usually occur in wireless systems.
