Abstract. The article describes the design and realization of a smart streetlight prototype. The lamp is designed to implement a comprehensive system of Smart Cities and Smart Lighting in the research and development of IoT issues. In addi‐ tion to the possibility of wireless switching, the lamp contains switching and dimming, as well as sensors for measuring temperature, humidity, and pressure, and it is equipped with a PIR sensor for switching the lamp when a person passes through its active field. All communication with the parental system, including the collection and processing of data is performed by IQRF technology. It also allows the creation of an extensive IQMESH network of these lamps.

Introduction
In recent years, there has been a big boom in the introduction of new technologies into the daily life of man. This includes the implementation of various microelectronic systems in commonly used items such as watches, wearable clothes, health care - see [12], automobiles – see [2], home appliances – see [11] and others. It is closely related to the development of the Internet of Things. Various studies indicate that by 2020, up to 50 billion devices will be connected to the Internet. The so-called SMART complex solutions, such as Smart Cities, Smart parking, Smart Lighting and others, are also undergoing a big development. The basis for communication between the individual components of these large systems should be low power technology that enables the transmission of necessary data from the deployment location to the parental system. Currently, technologies for wireless communications, such as LoRa, SIGFOX or NarrowBand-IoT, have been emerging globally. These solutions have their advantages, but also disadvantages that hamper the deployment within SMART projects. One disad‐ vantage is the energy intensity when transmitting 1B data. Another disadvantage is the amount of transmitted data for one device. The advantage may be high reach, which, however, loses its sense in urban development. An alternative to the above-mentioned solution may be IQRF technology, see [13]. This technology allows communication at a lower direct distance than, for example, LoRa SIGFOX; however, energy intensity © Springer Science+Business Media Singapore 2018 K.J. Kim and N.
