Soft handoff and interference management in femtocell network

Femtocell technology has gradually evolved in the field of wireless technology. Femtocell base stations (FBS) are installed mainly indoor to improve the signal coverage for the user held equipment. Interference management is of prime concern in FBS installation. The work is carried on understanding the Dynamic Assignment of Transmit Power for interference avoidance in co-tier femtocell networks. The drawback of dropping Femtocell User Equipment (FUE) has been identified. Solution to the problem is achieved by introducing handoff mechanism. Several handoff strategies have been categorized under survey. The work proposes handoff strategy, appended with existing Dynamic Assignment of Transmit Power system. The formulation to Dynamic Assignment of Transmit Power-Handoff (DATP-H) improves the throughput of existing system.
