Power control is a burning issue in modern wireless communication systems. Specially, in systems based on Code Division Multiple Access (CDMA) technology used in Universal Mobile Telecommunication System (UMTS), power control is adopted for maximizing the overall capacity of wireless system and battery life of mobiles terminals. A number of adaptive methods for power control in UMTS for different outdoor environments were reported in literature, but the focus on power control for indoor environments remained negligible. So, this to perform a comparative analysis of above mentioned power control techniques for different indoor propagation models. Performance evaluation was carried out on the basis of overall Spectral Efficiency (SE) and Power Control Error (PCE).
