Abstract: Femtocell power calibration is one of the key techniques for managing interference between femtocells and macrocells due to their unplanned deployment and restricted access. To ensure robust performance, rather than using a fixed transmit (Tx) power level for all femtocells in the network, power of each femtocell must be chosen based on its surrounding RF conditions. This requires calibration of Tx power for each femtocell. To achieve this goal, a suite of power calibration techniques has been designed to ensure satisfactory femtocell coverage with minimal interference to other cells. An overview of these power calibration techniques is provided
in the paper.
