The proliferation of LTE networks has
increased vulnerabilities to unauthorized
communication and security breaches, necessitating
controlled signal suppression in sensitive areas. Existing
studies on LTE jamming and detection often focus on
selective interference, reinforcement learning-based
detection, or data-driven anomaly analysis, yet they are
limited by support for only LTE, computational
complexity, environment-specific deployment, or
dependency on KPI availability. The present study
implements a 4G signal jammer using an oscillator for
precise LTE carrier generation, a noise generator to
produce broadband interference, an RF amplifier for
stable output, and an omnidirectional antenna for
uniform coverage. Field evaluation demonstrated
complete connectivity loss within a 12-meter radius, a
41 dB reduction in RSSI, and harmonic suppression
greater than 38 dB, outperforming previous approaches
that either lacked controlled coverage or produced
partial disruption. Results confirm reliable and uniform
jamming performance, validating the system’s
applicability for controlled environments such as
examination halls, research laboratories, and secure
facilities.
