Overview of the New Signal Jamming Law in Indiana

As modern technology continues to evolve, so does the landscape of criminal behavior—and the laws designed to combat it. One such advancement is the rise of signal jamming devices, which can be used to block or interfere with wireless communication signals such as cellular, Wi-Fi, and GPS. While originally developed for legitimate security and military purposes, these devices have increasingly found their way into civilian hands, often with dangerous or unlawful intent. In response, the Indiana General Assembly has taken decisive legislative action. As of 2025, Indiana Code 35-45-2-6 introduces strict penalties for the use or possession of signal jamming devices in unauthorized contexts. This new signal jamming law in Indiana criminalizes actions that threaten public safety, compromise criminal investigations, and obstruct justice. 

Understanding the scope and impact of this law is critical—not just for legal professionals, but also for individuals, business owners, and anyone who interacts with wireless communication systems. In this post, the Indiana criminal defense attorneys at Keffer Hirschauer LLP explain what this new Indiana law on signal jamming devices entails, whom it affects, and how to respond if you find yourself accused of violating it.

What Is Signal Jamming? 

Signal jamming refers to the deliberate interference with wireless communication signals. This is typically accomplished through a device that emits radio frequencies strong enough to disrupt, block, or overpower the signals transmitted by other electronic devices. Common targets include cellular phones, Wi-Fi networks, GPS tracking systems, and radio communications. 

These devices—commonly known as signal jammers, GPS blockers, or cell phone jammers—can range in size and sophistication. Some are small enough to fit in a pocket, while others are designed for more powerful, long-range use. Although often marketed online for purposes such as privacy protection or classroom control, their unauthorized use is illegal under federal law and now, under state law in Indiana as well. 

The Federal Communications Commission (FCC) has long prohibited the marketing, sale, and use of signal jammers due to their potential to interfere with emergency services and critical infrastructure. Indiana has now joined this effort at the state level by enacting a dedicated signal jamming law in Indiana to address the growing misuse of these technologies in criminal schemes—particularly in retail theft operations and electronic monitoring evasions. 

The New Signal Jamming Law in Indiana 

In response to the rising misuse of signal jamming devices, the 2025 Indiana General Assembly passed Senate Bill 26, which officially criminalizes both the use and possession of such devices in unauthorized contexts. 

Key Provisions of Indiana’s Signal Jamming Law 

• Use of a Signal Jamming Device: It is now a Level 6 felony in Indiana to knowingly or intentionally use a device to interfere with, block, or jam communication signals—including cellular, Wi-Fi, radio, or GPS transmissions. In addition, this charge may be elevated to a Level 5 felony if the jammer is used to disrupt a a component of a critical infrastructure facility or the communications of a public safety agency, such as law enforcement or fire safety.  
• Possession with Intent to Use: It is a Class A criminal misdemeanor in Indiana to knowingly or intentionally possess a signal jamming device with the intent to interfere with communication systems unlawfully. 

This law reflects growing concerns over the use of these devices in organized criminal activities. Organized retail theft rings, for example, have employed signal jammers to disable security systems or block employee communication. Similarly, individuals subject to electronic monitoring (such as GPS ankle monitors) have used jammers in attempts to avoid detection by law enforcement. 

Exceptions and Lawful Use 

While Indiana Code 35-45-2-6 imposes strict penalties for the misuse of signal jamming devices, the statute does carve out important exceptions for certain lawful activities. Understanding these exemptions is critical to ensuring compliance and avoiding inadvertent legal exposure. 

Law Enforcement and Government Agencies 

The statute does not apply to the use of signal jammers by law enforcement officers, correctional authorities, or other governmental entities acting within the scope of their official duties. Such use may include tactical operations, controlled security environments, or facilities where signal suppression is legally authorized. These exemptions recognize that in certain circumstances—such as hostage situations, prison security, or high-risk law enforcement operations—signal disruption can be a necessary and legally justified tool. 

Federally Authorized Use 

Indiana’s statute also defers to federal law regarding signal jamming. The FCC strictly regulates the sale, possession, and operation of signal jammers. Under federal law, only authorized federal agencies may operate these devices. Private individuals or entities are broadly prohibited from importing, marketing, or using them. Therefore, possession or operation of a signal jammer may be lawful only if explicitly authorized by federal regulation; and used in accordance with federal guidelines. 

Illustrative Examples 

• Lawful Use: A federal agency conducting a classified operation involving RF suppression within a secured perimeter. 
• Unlawful Use: A civilian using a signal jammer to disable store surveillance during a theft or to block GPS tracking on a vehicle under court-ordered monitoring. 

These exceptions are narrow and should not be interpreted as a general license to possess or experiment with signal jamming devices. The burden of proving lawful intent or exemption typically falls on the individual, making proper legal counsel essential when questions arise. 

Legal and Practical Implications of Indiana’s New Signal Jamming Law 

The enactment of Indiana’s new law on signal jamming devices demonstrates a broader trend in state and federal law to address the growing threat posed by signal jamming technology. For Indiana residents, the new signal jamming law in Indiana introduces both criminal liability and broader legal exposure. Understanding the practical ramifications is essential for compliance and risk mitigation. 

Penalties for Violation 

Violations of IC 35-45-2-6 carry substantial criminal consequences under the Indiana sentencing guidelines: 

• Level 5 Felony (Disruption of critical infrastructure facility or public safety agency): Up to 6 years in prison and fines up to $10,000 
• Level 6 Felony (Use of device): Up to 2.5 years in prison and fines up to $10,000. 
• Class A Misdemeanor (Possession with intent): Up to 1 year in jail and fines up to $5,000. 

Additionally, a felony conviction may result in long-term criminal record implications and collateral consequences. This includes a potential threat to professional licensure in Indiana; enhanced penalties for repeat offenses; loss of firearm rights; and/or immigration or employment-related consequences 

Real-World Impact on Hoosiers 

Indiana’s new signal jamming law will have a significant impact on everyday Hoosiers. First, individuals purchasing inexpensive jammers online—often unaware of their illegality—may face criminal charges for possession alone if intent to use is established. Employers in retail, logistics, or surveillance industries must be vigilant as well. Unauthorized possession or deployment of signal suppression tools, even for perceived security benefits, could lead to liability. Finally, monitored individuals, such s those on probation in Indiana, may be prosecuted for tampering or interfering with those systems using jamming devices, risking additional criminal charges.
