Estudio y análisis de las nuevas tecnologías 802.11ax y 5G para el desarrollo del internet de las cosas.

Abstract

Internet of Things (IoT), also called Internet of Objects, is undoubtedly the next evolution of the internet. It will be one of the greatest advances in the science of telecommunications for its capabilities to collect, analyze and distribute data that will become valuable information to process. Currently, there are different technologies that have not helped to fully develop IoT, among them is the already consolidated Long-Term Evolution (LTE) for cellular networks and the well-known Wi-Fi, in its version less named as IEEE 802.11ac (Wi-Fi 5). Both have very good connectivity features, but they are not enough to connect a world of heterogeneous smart devices. To address this, both technologies are being completely renewed and thus be able to exploit the true potential of IoT. The new 802.11ax standard (Wi-Fi 6) and the Fifth Generation of Mobile Networks (5G) promise to revolutionize the industry and develop an ecosystem suitable for IoT. In this document, the solutions that both standards have been developing to support the IoT application, together with their associated technologies, are studied. In addition, the new WiFi Alliance standard is analyzed in detail, which will renew one of its primary functions, such as OFDM and add mechanisms inherited from other standards such as; BSS Color and Target Wake Time that will give Wi-Fi all the robustness and efficiency needed to support a diverse range of smart devices. Meanwhile, 5G driven by the Third Generation Partnership Project (3GPP) developed the LowPower Wide Area (LPWA) solution to support new services and requirements for IoT and masstype machine communications (mMTC), Narrowband-Internet of Things (NBIoT) and LTE-M.
