Modern local area networks of the Wi-Fi standard have many advantages: high communication speed, mobility and a large number of simultaneously connected devices. Nevertheless, there is a significant drawback of this standard related to the small communication radius, which significantly limits the scope of this technology. First of all, this concerns the connection of Internet of Things (IoT) devices. For these purposes, it is necessary to develop separate standards, for example: LPWAN, NB-IoT, LoRA and others. This article substantiates the possibility of using the DECT standard as a universal standard for the IoT, digital telephony, etc. The paper formulates the basic requirements for a wireless network for local needs, such as an extended communication radius, an unfilled frequency spectrum, and energy-saving capabilities. It is shown that DECT satisfies all conditions well. The fundamental possibility of encapsulating MQTT messages in SIP messages is demonstrated. A new communication scheme has been proposed that allows for the transmission of MQTT control messages to an IoT sensor. It describes how the delivery of IoT control messages based on subscriber numbers in SIP can be implemented. The proposed communication scheme allows simultaneous provision of two communication services: radiotelephony and last mile for wireless connection of IoT devices. The application of the proposed solution for the creation of remote laboratories for the research and study of IoT networks and DECT technology is described.

Современные локальные сети стандарта Wi-Fi обладают множеством преимуществ, прежде всего, высокой скоростью связи, мобильностью и возможностью одновременного подключения большого числа устройств. Тем не менее есть существенный недостаток данного стандарта, связанный с малым радиусом связи, что существенно ограничивает область применения данной технологии. Это касается, в первую очередь, подключения устройств Интернета вещей (IoT). Для этих целей приходится разрабатывать отдельные стандарты. В данной статье обоснована возможность использования стандарта DECT в качестве универсального стандарта для IoT, цифровой телефонии и т. д. В работе сформулированы основные требования к беспроводной сети для локальных нужд, такие как увеличенный радиус связи, незаполненный спектр частот и возможности энергосбережения. Показано, что стандарт DECT хорошо удовлетворяет всем условиям. Продемонстрирована принципиальная возможность инкапсуляции сообщений MQTT (Message Queuing Telemetry Transport) в сообщения SIP (Session Initiation Protocol). Предложена новая схема связи, которая позволяет реализовать передачу управляющих MQTT-сообщений на сенсор IoT. Описано, как может быть реализована доставка управляющих IoT-сообщений на основе абонентских номеров в SIP. Предложенная схема связи позволяет одновременно оказывать две услуги связи: радиотелефонии и последней мили для беспроводного подключения IoT-устройств. Описано применение предложенного решения для создания удаленных лабораторий для исследования и изучения IoT-сетей и технологии DECT.
