    • An apparatus and method for adding and removing a target base station from a network of base stations, which includes base stations adjacent the target base station. The apparatus is comprised of two attenuators: a first for setting an artificial receive noise power level and a second for setting a transmit level. The transmit level determines the forward link coverage area of the base station. The artificial noise level sets the reverse link coverage area of the base station. When a base station is added, initially the transmit power is low and the artificial receive noise power is high such that the forward and reverse link coverage areas are collocated in close proximity to the base station. As the base station blossoms into full operation, the artificial receive noise power is decreased and the transmit level is increased such that the two coverage areas of the base station remain balanced as the coverage areas expand. When a base station is to be removed from a system, the same attenuators are used to wilt the two coverage areas in unison as the power level transmitted from the base station decreases.
    • 一种用于从包括与所述目标基站相邻的基站的基站网络中添加和去除目标基站的装置和方法。 该装置包括两个衰减器:第一个用于设置人造接收噪声功率电平,另一个用于设置发射电平。 发送电平确定基站的前向链路覆盖区域。 人造噪声电平设置基站的反向链路覆盖区域。 当添加基站时,最初的发射功率低,并且人为接收噪声功率较高,使得前向链路覆盖区域和反向链路覆盖区域在基站附近并置。 随着基站开始全面运行,人造接收噪声功率降低,发射等级增加,使得基站的两个覆盖区域随着覆盖区域的扩大而保持平衡。 当要从系统中移除基站时,由于从基站传输的功率电平减小,所以使用相同的衰减器来一致地使两个覆盖区域下降。
