Abstract
The 802.11ax high-efficiency wireless (HEW) particularly designed for high-density areas. However, dense areas have specific requirements that demand precise deployment strategies by network developers. In dense networks, a large number of users are simultaneously connected to the same channel; hence, the available bandwidth is divided among the users in such a way that joining more users can eventually saturate the network. Furthermore, in dense areas, a large number of closely spaced users are transmitting data at the same time. In such a heavily frequency interfered environment, the wireless link quality extremely degrades, which can practically render the network unavailable. Thereby, it is essential to determine the appropriate deployment options regarding the specific networks’ settings and configurations. Hence, this work proposes a network architecture model to determine the dual-band HEW performance in dense deployments. The model additionally includes long-term evolution (LTE) as the cellular alternative for high-density areas which is utilized by the model as the reference point for corresponding comparison purposes with HEW. The model is implemented, and link quality parameters are measured based on different aspects of the deployment options. To further validate the model and determine the optimization levels provided by the options, the simulation and analytical results are compared.

The explosive growth of mobile broadband traffic is one of the current major challenges in the mobile industry
The results indicate a better performance of high-efficiency wireless (HEW) over long-term evolution (LTE) in high-density conditions
Due to increasing reliability and decreasing error probability, this method is suitable for noisy networks for instance under high-density conditions where many users in a close distance are communicating on the same link. When it comes to HEW-2.4 and HEW-5 networks, despite observing much better performance in HEW-5 compared to the HEW-2.4 network, the results show that changing the antenna
Summary
The explosive growth of mobile broadband traffic is one of the current major challenges in the mobile industry. Despite the importance, there is no current work to address the limitations and implementation issues of dual-band HEW in dense areas through the appropriate selection of the deployment options identifying which is our first motivation. The. Wireless Communications and Mobile Computing options include operating channel management, connection limit, antenna configuration, bandwidth requirements, Internet protocol efficiency, and payload size distribution. Wireless Communications and Mobile Computing options include operating channel management, connection limit, antenna configuration, bandwidth requirements, Internet protocol efficiency, and payload size distribution In this regard, determining the optimal values of the deployment options to further enhance the link quality and network capacity of HEW compared to LTE in dense areas is the second contribution of this work.
