This project focuses on the implementation of a sectoral broadband coverage inhibitor to address the management and control needs of the electromagnetic spectrum, providing a controlled and secure environment to avoid interference from unwanted signals in wireless communications. Due to the growing dependence on wireless communications, GSM, LTE, WiFi, and Bluetooth technologies were selected. To achieve the design objective, advanced techniques were used to generate a significant noise signal and modulation to ensure signal interference efficiency by suppressing all communications in specific frequency bands within a selected area. Several experimental tests were carried out, proposing a scenario that took into account the presence or absence of people, so that several results were obtained, in addition to the decision to use power amplifiers, recording power values at different distances, taking into account the The same process was carried out for each technology.
