Public Safety Organizations Sign Joint Letter Opposing NextNav Petition to the FCC

The Association of Public-Safety Communications Officials-International (APCO), International Association of Chiefs of Police (IACP), International Association of Fire Chiefs (IAFC) and National Sheriffs’ Association (NSA) signed a joint letter to the FCC outlining their concerns that NextNav’s proposed PNT solutions could negatively affect existing incumbent operations essential to the preservation of life and safety.

The letter references the evidence from recent reports and studies, such as the engineering review submitted into the record by Pericle that highlights potential risks of NextNav’s proposal to critical life safety systems noting that these systems are prevalent throughout our country, especially in Americans’ homes and businesses. The letter states that the rule changes requested in the NextNav petition could have significant negative consequences for public safety.

The letter, dated November 13, 2025,  calls out key examples of devices that could be affected if NextNav’s proposals were allowed to proceed:

• Man down systems/solutions. These devices and solutions help provide public safety agencies with the location of first responders and other pertinent life-safety data while on the scene of an incident. They are especially critical for public safety personnel, because they provide critical tracking data for first responders in unfamiliar settings.
• Self-Contained Breathing Apparatus (SCBA) systems. SCBA systems provide respiratory protection for first responders in hazardous environments, including fire and areas with toxic gas. These devices may incorporate connectivity features over the Lower 900 MHz band to monitor firefighter status, air supply levels, and environmental conditions. This enables remote monitoring of air cylinder pressures, automatic alerts if a wearer is in distress or immobile, and integration with incident management software for real-time safety oversight.
• IoT wildfire sensing and wind profile radars. Connected cameras and sensors equipped with AI use the Lower 900 MHz band to detect environmental conditions conducive to wildfires and create wind predictions for wildfire mitigation. These systems provide early warning and situational awareness to inform public safety decision-making and resource deployment.
• Preemption of traffic signals. These devices help emergency vehicles override typical traffic signal operations. They ensure that emergency vehicles have the right-of-way and can reach the incident scene in a quick and timely manner.
• Automatic utility gas/electric shut off capabilities. When first responders encounter a scene where live electricity or a gas leak is present, often their first call is to utility companies. Remote shut-off systems operate on the Lower 900 MHz Band. If gas and electric companies cannot operate their remote shut off systems, first responders’ lives and safety could be at risk.
• Smoke and carbon monoxide detectors: These detectors can be found in the homes of most American citizens. These devices alert people to unsafe levels of smoke or carbon monoxide present in residences or businesses, so that people can evacuate safely. These detectors are often connected directly to alarm companies to allow first responders to arrive on the scene more quickly.
