Design Characteristics of Soft Handoff in Uplink Two – Tier CDMA Syst

Jafaar Fahad A. Rida; Rajeev Paulus; Alok Singh; Neha Ujala Tirkey
Wireless operators often encounter small region of dense user’s traffic with a large coverage area (Macrocell).This paper studies a problem in smaller region coverage with high capacity (high density population) is little active. The Overlay is small cells tessellate almost all of the coverage area of the large (Umbrella), and the Hotspot smaller region coverage area with high traffic which needs low power and low cost units mounted on side of buildings. A large user capacity means that system supports a large of users per unit bandwidth which in turn implies higher revenues per unit cost (spectrum). In CDMA using uniquely code each user and frequency fixed using soft handoff in this system mean break old channel to call after transfer to new channel to new cell .Our simulation results demonstrate 40% increase user capacity compared to hard handoff
