Handoff algorithms are a cost-effective way of enhancing the capacity and QoS of cellular system. The higher value of hysteresis effectively prevents unnecessary handoffs but causes undesired cell dragging. This undesired cell dragging causes interference or could lead to dropped calls in microcellular environment. The problems are further exacerbated by the corner effect phenomenon which causes the signal level to drop by 20–30 dB in 10–20 meters. Thus, in order to maintain reliable communication in a microcellular system new and better handoff algorithms must be developed. In this paper we present short reaction time handoff suitable for microcellular systems. The slopes of natural (expected) signal and the actual signal are compared and then handoff decision is made by fixing a threshold value.
