Fourth and fifth generation (4G-5G) cellular networks provide key enabling technologies for theubiquitous deployment of Internet of Things(IoT) technology. This has allowed the implementationof different use cases or applications that have allowed their operation to be evaluated. Alignedwith several research studies around 5G and 4G that are currently being carried out, this researchproposes the implementation of a use case for the measurement and transmission of air quality inBogot´a- Colombia, through the Internet of things and simulations in Software Defined Radio (GNURadio).As a result, network performance indicators were obtained that make the application viableboth in data acquisition and transmission, in the use case for air quality. In that sense, this researchmakes it possible to establish the basis for real operations in future implementations of emergenttechnologies in the city.
