It is particularly important for governments to regulate and control efficiently the use of this resource, as it is a strategic resource. The governments carry out the management of the radioelectric spectrum, but the demand for it, the increase of new wireless technologies and the misuse that certain clandestine companies make with the spectrum, require monitoring systems that are more efficient and sustained than the conventional equipment many times can not satisfy. Therefore, there are currently alternatives based on the concept of open source hardware and software that can be used to support spectrum monitoring activities using new concepts and architectures. This article presents an alternative for these measurements, which is known as software defined radio. This is a technique to build devices in which part of the hardware can be replaced by software routines, which reduces costs. The case of electromagnetic spectrum monitoring in the FM radio band in the city of Guayaquil in Ecuador is presented, using the parameters defined by the ARCOTEL local regulatory entity.
