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.

高密度区域长期演进和802.11ax的链路质量改善

802.11ax高效无线（HEW）专为高密度区域而设计。但是，密集区域具有特定要求，需要网络开发人员制定精确的部署策略。在密集的网络中，大量用户同时连接到同一通道。因此，可用带宽以这样一种方式在用户之间分配，即加入更多用户最终可以使网络饱和。此外，在密集区域中，大量紧密间隔的用户正在同时传输数据。在这种频率严重干扰的环境中，无线链路质量会大大降低，这实际上会使网络不可用。因此，必须确定有关特定网络设置和配置的适当部署选项。因此，这项工作提出了一种网络体系结构模型，以确定密集部署中的双频HEW性能。该模型还包括长期演进（LTE）作为高密度区域的蜂窝替代方案，该模型将其用作参考点，与HEW进行相应的比较。该模型已实现，并根据部署选项的不同方面测量了链路质量参数。为了进一步验证模型并确定选项提供的优化级别，对模拟和分析结果进行了比较。该模型还包括长期演进（LTE）作为高密度区域的蜂窝替代方案，模型将其用作参考点，以与HEW进行相应的比较。该模型已实现，并根据部署选项的不同方面测量了链路质量参数。为了进一步验证模型并确定选项提供的优化级别，对模拟和分析结果进行了比较。该模型还包括长期演进（LTE）作为高密度区域的蜂窝替代方案，该模型将其用作参考点，与HEW进行相应的比较。该模型已实现，并根据部署选项的不同方面测量了链路质量参数。为了进一步验证模型并确定选项提供的优化级别，对模拟和分析结果进行了比较。
