Senate Pushes Enforcement Against Jammers Used in Cargo Theft

Mexico’s Senate is seeking stronger action against the online sale of signal jammers, which can disable GPS and communications systems used to protect cargo fleets. While cargo theft fell in April, the continued availability of these devices highlights persistent security gaps across Mexico’s freight corridors.

Mexico’s Senate is seeking stronger action against the online sale of signal jammers, devices widely used by criminal groups to disrupt GPS, cellular, and data transmissions during cargo theft.

The renewed legislative focus comes despite the existence of Mexico’s so-called Anti-Jammer Law, which has prohibited the manufacture, commercialization, acquisition, installation, possession, use, and operation of equipment designed to block or cancel telecommunications signals since 2020.

Under Article 190 Bis of the Federal Telecommunications and Broadcasting Law, jammers are prohibited except in limited cases involving authorized security and penitentiary institutions. Article 168 Ter of the Federal Penal Code establishes prison sentences of 12 to 15 years for individuals who manufacture, sell, acquire, install, carry, use, or operate the devices illegally.

However, the continued availability of jammers through digital platforms, social media, and informal online channels has raised concerns over the effectiveness of enforcement. These devices can interrupt GPS tracking systems, mobile communications, and data transmissions, creating communication gaps that allow criminal groups to intercept cargo units without immediate detection.

A Persistent Risk for Cargo Transport

For Mexico’s cargo transport sector, jammers remain one of the most disruptive tools used in highway robberies. By blocking tracking and communication systems, criminals can prevent logistics operators, security providers, and fleet managers from identifying the location of a stolen truck or activating response protocols in real time.

While cargo theft fell 15.6% year-on-year in April, reaching 385 reported incidents, the decline did not eliminate the structural vulnerabilities facing carriers, particularly in the State of Mexico, Puebla, Guanajuato, Veracruz, and other high-risk areas for freight movement, reports MBN.

The use of signal inhibitors is particularly concerning because cargo transport increasingly depends on digital monitoring systems. GPS devices, geofencing tools, telematics platforms, panic buttons, and mobile communications are central to fleet-security strategies, especially on high-risk corridors.

Industry organizations have repeatedly warned that the use of jammers is not isolated. In 2024, the Mexican Association of Private Security Companies and Satellite Industry reported that 81% of cargo theft cases registered by its members involved the use of signal inhibitors. The association argued that authorities needed to apply the existing legal framework more effectively and strengthen the detection of jammers on highways.

The group also proposed deploying jammer detectors on strategic road corridors, arguing that the possession of these devices is already a criminal offense under federal law.

Enforcement Beyond Legislation

The Senate’s renewed call reflects a broader challenge for cargo-security policy: legislation alone cannot prevent the use of jammers if devices remain easily accessible through online channels.

Stronger enforcement could require coordination between federal security authorities, telecommunications regulators, state police forces, digital-platform operators, and cargo-security companies. Monitoring online sales, identifying import channels, investigating distributors, and improving roadside detection would be necessary to reduce the circulation of illegal equipment.

For transport operators, the issue also reinforces the importance of layered security strategies. GPS tracking alone may not be enough when criminals use tools designed to block satellite and cellular signals. Companies are increasingly combining tracking systems with backup communications, hidden recovery devices, route-risk analysis, geofencing, and real-time monitoring centers.
