Performance optimization of smartphones in dual-band high-efficiency and very high throughput mobile networks

Abstract

By focusing on dense areas, 802.11ax high-efficiency wireless (HEW) standard offers some improvements over 802.11ac very high throughput (VHT). The HEW improvements are mainly based on several key factors and diversity of their values. While each particular value corresponds to a key factor can directly affect the network performance, there is a great deal of uncertainty regarding their practical effectiveness in dense areas. Thus, identifying the efficiency of each particular value of the key factors is of prime importance for determining the optimal values and thereby enhancing the network performance. However, identifying the optimal values in wireless dense areas where a large number of users share the same link is a challenging task and needs comprehensive comparative approaches. In this context, this work proposes a model for high-density HEW and VHT deployment with a special focus on their common key factors. The model includes 204 distinct simulation scenarios, categorized under six major classes, each corresponds to a particular key factor. The model is implemented and the results are obtained to determine the optimal values of the key factors. Moreover, to validate the accuracy of the simulation results, the analytical results are obtained and compared.
