This article discusses one method for improving the efficiency of an information system that is capable of providing cloud services. The topic is relevant, because over time, more and more users are switching or planning to switch to cloud services. To consider methods for increasing the efficiency of an information system, an analysis is made of saving user funds and resources, ways of creating the possibility of remote access to services, methods of obtaining the possibility of using individual services at a certain level of abstraction in order to match these services to various user needs. The task is to study methods of increasing the efficiency of the use of cloud services by introducing IEEE 802.11ax technology and determining the directions and prospects of its use. To achieve the goal, empirical methods were used in the analysis of services, signs for their classification are determined, namely: a data storage or backup service; On-line office; On-line accounting; specialized Internet applications; closed private clouds for team management and customer relationship management; combinational services; applied cloud services. The advantages of cloud services are determined: scalability, flexibility, relevance, ease of access. Defines the cloud computing front-end and back-end architecture. This makes it possible to formulate the requirements for telecommunication access facilities to provide cloud services, as far as possible, namely: good quality of connection in places with a high density of users; creation of a Wi-Fi network with high bandwidth and low latency; support for previous versions of Wi-Fi devices; expansion of application in IoT networks; application of Wi-Fi infrastructure in target markets; creation of applications for IoT using technology and management of the parameter of the target wakeup time (Target-Wakeup Time); application for creating virtual reality (Virtual reality, VR); application to create augmented reality (AR); application for providing video content in Ultra HD mode; application in real-time applications, significant energy savings in the connected device. An analysis is performed of Wi-Fi technologies that are capable of meeting the specified requirements. It is concluded that this is possible when using the IEEE 802.11 standard.
