HERRERA RUBIO, Jorge Enrique; SANCHEZ MOJICA, Karla Yohana  e  LOPEZ JARAMILLO, Edwin Arley. IoT layered model study for downlinks in Sifgox network interconnection platform. Rev. logos cienc. tecnol. [online]. 2021, vol.13, n.3, pp.46-56.  Epub 20-Nov-2021. ISSN 2145-594X.  https://doi.org/10.22335/rlct.v13i3.1454.

The purpose of the research was based on the analysis of the operation of the layered model of the internet of things structure of the Sigfox network in order to observe the behavior of data transmission. It was determined, through the quantitative approach, the study of the hardware platform with a test prototype to measure the performance and range of a radio link for the coverage of a wireless cell. By sampling the physical variables, these are captured with a mobile device and then processed to observe how is the connection with the database to the web server in real time. In the field analysis, the operation of the downlink and the communication process of the middleware as an intermediary in the interconnection platform were checked, the power levels and signal to noise ratio of the test link were observed. Based on the layered model it is more feasible to understand the functionality of the communication protocols to maintain access to the heterogeneity of the network and the interopera bility of services and applications. With this type of ultra-narrow band technologies a low error rate is possible due to the high resistance to noise.
