    Конвергенція послуг 4G з WI-FI

    Researched basic requirements for the convergence of services 4G with Wi-Fi, which lie in the field of security, simplicity and ease of use, high quality and reliability. For simplicity and ease of use, features such as automatic au-thorization and connection, seamless roaming, user management and location monitoring are important. Quality and reliability imply efficient management of a large number (hundreds and thousands) of Wi-Fi access points, mobile traffic unloading (Wi-Fi Offload) and quality of service (QoS) management. At the same time, one of the key condi-tions for convergence lies within the framework of the program-defined network concept (SDN). For example, we are talking about the use of software for centralized management of high-density Wi-Fi networks. This, in particular, makes it possible to implement mechanisms for end-to-end traffic and frequency resource management in convergent Wi-Fi / 4G networks, which can be positioned as one of the key features of the capabilities of smart Wi-Fi networks.

    Перспективи розвитку технології мобільного зв’язку 4G
    (ХНУРЕ, 2019) Сабурова, С. А.; Кадацкая, О. И.; Козубенко, В. С.
    The organization of subscriber access to multiservice 4G-based networks are relevant in the light of providing subscribers with high-speed latest technology and new services. The main feture of the current stage of development of cellular communication systems is the transition to fourth-generation systems. The transition to LTE-Аdvanced (4G) networks allows us to qualitatively change the current situation in the field of mobile communications. This is due primarily to the fact that LTE-Аdvanced networks can provide customers with a wide range of new services that can significantly increase the revenues of operators, and for manufacturers - sales of network equipment and telephones.
