In modern wireless networks the number of users and the volume of transmitted traffic are continuously increasing, imposing strict requirements on throughput and quality of service. These requirements are especially high for virtual reality (VR) applications, which are sensitive to delays and frame losses. Increasing the number of access points can potentially improve the throughput of Wi-Fi networks. However, in practice, it leads to higher interference and reduced efficiency of random access. This paper considers an approach based on frequency coordination of access points using the Coordinated Orthogonal Frequency Division Multiple Access (C-OFDMA) method. A recursive algorithm for frequency resource allocation is proposed, which takes into account the characteristics of VR traffic and ensures flexible utilization of radio resources. The study compares existing data transmission methods in Wi-Fi networks with the proposed approach for serving VR traffic. The use of the developed algorithm improves network performance and increases the number of satisfied users compared to other data transmission methods.
