Multi-frequency modem in the Internet of Things technology

The Internet of Things technology provides modern opportunities for the construction of facilities, is dynamic and promising, connecting devices (for example, to the monitoring system) through communication systems using a multi-frequency modem. The dispatch service, interacting with sensors, collects information about events, making adjustments to the work using actuators, while there is a need for multi-frequency data transmission. Data provide information related to the object, allowing to control it. The technology in question is recognized as one of the most important technologies of the future, applied at all stages of the life cycle of a production project, which is presented (in tabular form) in the article (reflecting the advantages). The work describes in detail the need for Internet of Things technology in the construction of Intelligent Buildings, considers the principles of implementing the Internet of Things (with recommendations for implementation at a manufacturing enterprise), gives the main types and tools (meeting the requirements of the technology). The possibility of observing certain parameters of systems to optimize construction processes is shown (in tabular form). A simplified typical model of interaction between system modules, a network organization diagram, and its characteristics are given. The structural diagram of one of the channels of the developed modem reflects its ability to process broadcast information taking into account the feasibility of using a narrowband finite signal and its two derivatives. The NB-IoT technology is described, which is part of the 5G network standards for transmitting short messages by narrowband signals. The possibility of monitoring with control functions in messengers is mentioned (with an example of possible service indication). The Interuniversity WorldSkills Championships which are regularly held emphasize the relevance of the research topic, and the predicted growth of the Internet of Things expansion up to space confirms it. The article is devoted to an overview of the Internet of Things technology applied to the construction of hybrid communications systems of a digital city whilst the development of this technology continues, and a multi-frequency modem perfectly meets the needs of this technology.
