Abstract: Interference is the result of superimposing of two or more signals that causes change in original signal properties. Interference in wireless networks is of major concern these days. Many interference control algorithms have been proposed to overcome the same. In fact, interference can be only controlled but cannot be completely avoided. In femtocell network which is discussed in later section of this work, signal interference chances are more as in these networks, the base station are deployed in Ad-hoc environment also, these networks are responsible for in-building coverage to provide call continuity and to reduce the overhead of service providers in installing large towers and Base station antennas. The work develops the power control algorithm and simulate using MATlab to demonstrate the in-building environment with randomly distributed cell phone users with in the building and checking the interference at co-tier level (between two or more in-building base stations) both at uplink and downlink and then later introduce Dynamic Assignment of Transmit Power (DATP) algorithm to the situation and analyse how the interference is controlled.
