Now a days Handoff failure is a very challenging issue. This happen for several reasons. One is the number of channels are limited in a cell. In this article, we proposed a technique to increased the number of channels in a cell. Here we reduce the band gap between two channel. Guard band is used to prevent interference between radio band. Reducing the bandwidth of guard band, same amount of bandwidth which we reduced from the guard band are added to the effective useful band.So, by doing this we can increase the bandwidth of effective useful band.Each channel has a fixed size bandwidth, so the increasing bandwidth may occurs some extra channels.Hence, by using this we can increase the number of channel in a cell, which decreases the Handoff failure Probability.If there are available free channel then handoff initiation rate is increased and in that way we may reduce Handoff failure and can improve the probability of Handoff rate.
