With the growth of the size of the population of large cities, state authorities in different countries of the world are looking for ways to make cities, their infrastructure and energy systems more intelligent, safe and energy-efficient. In addition, the connection of vehicles to the global network gives city services more opportunities to interact with drivers for comfortable and efficient traffic management. However, as more and more control systems move to the use of cloud technologies, thereby creating Internet things (IoT), there are more opportunities for unauthorized access to confidential data. This article provides an overview of some of the fundamental technologies that have been developed in collaboration with Infineon, eluminocity and Intel, which make cities more intelligent in the future, as well as innovative lighting solutions that can become an integral part of smart cities integrated into the global network. Urbanization and access to new technologies are accelerating the demands of consumers on how comfortable their life will be in the near future. Until recently, the focus has been on the improvement of mobile devices and related products, but it is now becoming apparent that improved infrastructure plays an important role in the technological evolution of the world in which we live. Urban infrastructure developers are faced with increasingly complex problems and requirements that often contradict each other. On the one hand, they quickly introduce new technologies to add more functionality to the attributes of everyday life, for example, ordinary street lighting, and on the other, they try to minimize energy consumption due to the constant rise in the cost of energy carriers. In a new, more perfect, world street lantern, this is not just a source of light, but a multifunctional communication portal, which is the basis of intellectual urban infrastructure. In order to provide the necessary functionality and access to network resources, lighting designers use cellular technology, various types of sensors, both active and passive, as well as state-of-the-art information security solutions. Radar, operating in the 24 GHz band The radar detection method of objects is based on the use of reflected electromagnetic waves, through which it is possible to determine the distance to the object, the angle and speed of its movement. Typical radar systems (radars) include a transmitter generating electromagnetic pulses or continuous radiation in the radio frequency or microwave frequency range, separate transmitting and receiving antennas, and a receiver that receives and processes signals. The pulse radar measures the distance to the stationary or moving objects, generating a short, powerful pulse and taking a response reflected from the object. The time between the sent pulse and the received response is directly proportional to the distance from the radar system to the object. Radar with continuous radiation constantly generates electromagnetic waves with frequency modulation implemented in one of two ways (Figure 1). A radar with continuous frequency-modulated radiation (FMCW) is capable of detecting both stationary and moving objects by transmitting a linear frequency modulation signal that is mixed in the receiver with the received signal. The receiver's low-frequency output signals contain information about the distance to the object and its speed. Frequency hopping modulation, also called Frequency Handling (FSK), can be used to determine the distance only for moving objects. With this modulation method, the transmitter sequentially sends signals at two different frequencies, and the distance is determined by the Doppler shift of the phases of the received signals.

As object detection becomes increasingly sought after for intelligent systems and devices, 24 GHz radar equipment is used in various Internet applications of things, including multi-copy / drones, intelligent door locks, home and office automation systems, speed meters, robotics, and so on.
