Introduction:Effective synthesis of а mobile communication network includes joint optimisation of two processes: placement of base stations and frequency assignment. In real environments, the well-known cellular concept fails due to some reasons, such as not homogeneous traffic and non-isotropic wave propagation in the service area.Purpose:Looking for the universal method of finding a network structure close to the optimal.Results:The proposed approach is based on the idea of adaptive vector quantization of the network service area. As a result, it is reduced to a 2D discrete map split into zones with approximately equal number of service requests. In each zone, the algorithm finds such coordinates of its base station that provide the shortest average distance to all subscribers. This method takes into account the shortage of the a priory information about the current traffic, ensures maximum coverage of the service area, and what is not less important, significantly simplifies the process of frequency assignment.

Using strategies from critical race studies and feminist studies of science, medicine, and the body, we examine the covert operation of race and region in a regulation restricting the natural levels of testosterone in women athletes. Sport organizations claim the rule promotes fair competition and benefits the health of women athletes. Intersectional and postcolonial analyses have shown that "gender challenges" of specific women athletes engage racialized judgments about sex atypicality that emerged in the context of Western colonialism and are at the heart of Western modernity. Here, we introduce the concept of "T talk" to refer to the web of direct claims and indirect associations that circulate around testosterone as a material substance and a multivalent cultural symbol. In the case we discuss, T talk naturalizes the idea of sport as a masculine domain while deflecting attention from the racial politics of intrasex competition. Using regulation documents, scientific publications, media coverage, in-depth interviews, and sport officials’ public presentations, we show how this supposedly neutral and scientific regulation targets women of color from the Global South. Contrary to claims that the rule is beneficent, both racialization and medically-authorized harms are inherent to the regulation.
