Sistema cognitivo de petición de canales disponibles en la banda de frecuencia de 470mhz a 698 mhz para el despliegue de iot

Abstract

The radio spectrum is a natural resource that allows wireless communications for telecommunications services such as television, radio broadcasting, radionavigation, among others. The spectrum is managed in accordance with the recommendations established in the International Telecommunication Union (ITU) and the regulatory institutions of each country. The management of the frequencies allocation for primary and secondary users in the radio spectrum is a process of change, taking into account that the use of spectrum has low levels of use in some frequency bands. Therefore, dynamic allocation is seen as a solution to the efficient use of spectrum for emerging telecommunications services. The increase in the use of spectrum is a consequence of emerging telecommunications services such as the Internet of Things (IoT), taking into account that these services may have a low date rate, but a massive number of devices or multimedia contents may also be available. In these services, things can be considered as objects of everyday life such as appliances, transportation, among others. In addition, the connection of the devices to the Internet allows the development of new opportunities in social, economic and environmental spheres, among others, contributing tangibly to the community through the control, management and monitoring of physical elements that composes an urban environment within a net. The research is focus on frequency bands of dynamic television that allow new opportunities for the deployment of emerging services such as IoT. Therefore, this document of work seeks to review the current regulatory status of the radio spectrum with respect to the dynamic allocation in the 470MHz to 698MHz band, the use of this band for IoT devices and the protocol-level framework of the communication of the IoT devices in a network of spectral television white spaces TVWS.
