Simulation and analysis of interference avoidance using fractional frequency reuse (FFR) method in LTE femtocell

摘要

There for another way is needed to keep LTE reliable when use in indoor. Femtocell is the solution of the problem. But femtocell uses the same frequency spectrum as any other broadband services. The more femtocell used in an area, overall networks capacity will be disturbed by cochannel interference.
