Abstract
Femtocell can provide better indoor coverage and
capacity of cellular systems. In order to operate femtocell
appropriately, RF interference analysis between femtocells and
macrocells is needed. In this paper, we discussed the impact of
interference by the introduction of femtocell in Mobile WiMAX
system. Performance degradation was evaluated for the downlink
case by system level simulation. Simulation results shows that
the impact of interference from macrocell to femtocell is more
severe than from femtocell to macrocell. By allocating different
frequency bands for femtocell and macrocell, performance
degradation can be negligible.
