A New Chapter in Border Surveillance Technology
The US Department of Homeland Security, working alongside Defense Research and Development Canada, plans to send autonomous drones and ground vehicles along the northern border this fall. The goal is straightforward: test which systems can stream live surveillance video and sensor data between the two countries using commercial 5G networks. This experiment, called ACE-CASPER, represents the first joint US-Canada cross-border technology exercise in nearly a decade. For anyone tracking government surveillance expansion, this marks a significant shift in how border monitoring may operate in the years ahead.
The tests are scheduled for November and will unfold as a multiday exercise simulating a national emergency response scenario. Drones and ground vehicles will relay live feeds to a bi-national command-and-control center as they cross the border. While the public framing emphasizes search and rescue and emergency coordination, the language used in the procurement documents tells a more complex story. DHS describes capabilities in terms borrowed from military operations, asking vendors to demonstrate how autonomous vehicles can gather what it calls “real-time battlefield intelligence.” The aerial systems are referred to as C2ISR platforms, an acronym that stands for Command and Control, Intelligence, Surveillance, and Reconnaissance.
This article breaks down seven distinct ways DHS plans to conduct recon drone testing along the northern border. Each approach reveals something different about the technology, the partnerships, and the implications for privacy and security.
1. Streaming Surveillance Video Over Commercial 5G Networks
The primary objective of the ACE-CASPER experiment is not drone autonomy. It is communications resilience. DHS wants to see whether commercial 5G networks can reliably carry high-definition video feeds from drones and ground vehicles across an international border. This is harder than it sounds. Cellular networks are designed for consumer traffic, not for persistent, high-bandwidth surveillance streams moving through rural and remote terrain.
The test will involve drones flying along the US-Canada border while streaming live video to a command center that spans both countries. The 5G signal must remain stable as the drone crosses the boundary between two different national networks. Handoffs between carriers, signal degradation in sparsely populated areas, and latency issues all become critical variables. This recon drone testing scenario pushes commercial infrastructure far beyond its typical use case.
One challenge that often goes unnoticed is that 5G networks rely on dense arrays of small cell towers. Along the northern border, many stretches lack that infrastructure entirely. DHS and DRDC will need to identify corridors where coverage is strong enough to support the test, or they may need to deploy temporary boosters. The results will inform whether commercial 5G can serve as a backbone for future border surveillance operations.
2. Simulating a National Emergency Response Scenario
The exercise is framed as a simulated national emergency. This framing matters because it determines what kinds of data collection and coordination are considered legitimate. In an emergency, responders need real-time information about hazards, casualties, and infrastructure damage. Drones can provide that view from above. But the same technical capability that maps a flood zone can also track vehicle movements along a border.
The simulation will likely involve a fictional disaster scenario, such as a chemical spill, a wildfire, or a cross-border medical crisis. Responders on both sides will use the drone feeds to coordinate their actions. The question that privacy advocates raise is whether the infrastructure built for emergency response will remain in place afterward. Once 5G surveillance towers and drone launch sites are established, they can be repurposed for routine monitoring.
This is not a hypothetical concern. Under the earlier CAUSE program, which ran from 2011 to 2017, the US and Canada conducted five cross-border drills focused on radio interoperability and data sharing. Those exercises were also framed as emergency response. The technology tested in those drills later found its way into ongoing border security operations. The same pattern could repeat with ACE-CASPER.
3. Cross-Border Command and Control Integration
A central feature of the November tests is the bi-national command-and-control center. This facility will receive live feeds from drones and ground vehicles operating on both sides of the border. Operators in the US and Canada will need to coordinate in real time, sharing video, sensor data, and decision-making authority. This is a complex organizational challenge as much as a technical one.
During the CAUSE exercises, one of the biggest obstacles was simply getting radio systems to talk to each other. US and Canadian emergency responders used different frequencies, different protocols, and different equipment. The ACE-CASPER experiment aims to solve that problem at a higher level by using 5G as a common transport layer. If a drone flying over British Columbia can stream video to a command center in Washington state, the border becomes transparent to the data flow.
This aspect of recon drone testing has implications beyond emergency response. A command-and-control architecture that works for disaster coordination can also support persistent surveillance. The same video feeds that help responders locate a missing hiker can help border agents monitor unauthorized crossings. The technology itself is neutral, but the policy framework around its use determines the outcome.
4. Coordinating Autonomous Ground Vehicles with Aerial Drones
The experiment includes both aerial drones and ground vehicles. This dual-platform approach adds a layer of complexity. The drones provide a wide-area view from above, while the ground vehicles can inspect objects, read license plates, or deploy sensors at close range. Coordinating these two types of autonomous systems in real time requires sophisticated software and reliable communications.
Vehicle autonomy, according to the DHS procurement document, is secondary to the primary goal of demonstrating resilient 5G communications. But the two are linked. An autonomous ground vehicle that loses its network connection cannot receive updated navigation instructions or transmit its sensor data. The test will reveal how well these systems maintain functionality when the 5G signal fluctuates or drops entirely.
For a rural resident living near the border, the presence of autonomous vehicles raises practical questions. Will these drones and ground vehicles operate on private land? Will there be noise, visual intrusion, or safety risks? DHS has not released detailed maps of the test corridors. Residents in affected areas may not learn about the exercises until they see a drone overhead.
5. Testing Network Resilience Under Real-World Conditions
November along the northern border means cold weather, short daylight hours, and potentially challenging atmospheric conditions. These factors matter for 5G performance. Rain, snow, and fog can attenuate high-frequency signals. Cold temperatures affect battery life on drones and ground vehicles. The test will push the technology into conditions that laboratory simulations cannot replicate.
Resilience also means the ability to recover from network failures. If a 5G tower goes down, can the drone switch to a backup frequency or reroute its data through another node? Can the command center maintain situational awareness if the video feed freezes for ten seconds? These are the kinds of questions the ACE-CASPER experiment is designed to answer.
DHS describes the goal as “resilient, persistent 5G communications.” The word persistent is important. It means the network should stay up continuously, not just during peak hours or under ideal conditions. For border surveillance, persistence is everything. A system that works only 90 percent of the time leaves gaps that can be exploited. The November tests will reveal whether commercial 5G can meet that standard.
6. Gathering Real-Time Battlefield Intelligence in a Civilian Context
The language used in the DHS procurement documents is striking. Vendors are asked to demonstrate the ability to gather “real-time battlefield intelligence” using autonomous vehicles. The aerial systems are described as C2ISR platforms, a term borrowed directly from the Department of Defense. The document even references the improvement of “kill chains,” a military concept that describes the process of identifying, tracking, and engaging a target.
Why does a civilian homeland security agency use martial terminology for an emergency response exercise? One explanation is that the technology itself is dual-use. The same sensors, software, and communications systems that help soldiers locate enemy positions can help first responders find survivors in a disaster zone. DHS may be using military language because it is precise and well-understood within the procurement community.
But the terminology also signals a broader trend. The line between homeland security and military operations has blurred significantly over the past two decades. DHS now operates drones, surveillance towers, and AI-powered analytics along both borders. The agency’s Science and Technology Directorate sits at the center of the federal government’s domestic counter-drone program. The vocabulary of warfare is becoming the vocabulary of border enforcement.
For a privacy advocate watching this development, the concern is mission creep. If DHS trains its personnel to think in terms of battlefield intelligence and kill chains, will they apply that mindset to routine border monitoring? The ACE-CASPER experiment may be framed as emergency response, but the capabilities it tests have obvious applications for continuous surveillance.
7. Evaluating Vendor Systems for Future Procurement
The November tests are not just a research exercise. They are also a procurement pipeline. DHS is using the experiment to evaluate which vendors can deliver working systems. Companies that perform well will be well-positioned for future contracts. This is especially significant given recent policy changes that prioritize American-made drones and reserve government contracts for domestic manufacturers.
An executive order signed by President Trump in 2025 prioritized procurement of US-built drones. A recent FCC designation bars new foreign-made drones from US wireless networks. Together, these policies create a protected market for American drone manufacturers. The ACE-CASPER experiment is one of the first opportunities for domestic vendors to demonstrate their systems in a cross-border context.

Several companies with ties to the president’s adult sons are positioned to respond. Powerus Corporation, a Florida-based drone manufacturer, recently merged with a golf course company backed by Eric Trump and Donald Trump Jr. Anduril Industries, in which Trump Jr.’s firm invested, holds a $1.1 billion DHS border-security contract for AI-powered surveillance towers along the southern border. Unusual Machines, a drone-components maker where Trump Jr. served as an adviser, sells to suppliers who work with the government. Xtend, backed by Eric Trump, opened a Tampa headquarters in summer 2025 and holds a Pentagon contract.
This concentration of business relationships raises questions about how procurement decisions are made. The ACE-CASPER experiment will generate technical data about which systems perform best. But the policy environment and personal connections may influence which vendors get the most favorable consideration. For a small drone manufacturer trying to break into the government market, the playing field may not be level.
What the Nearly Decade-Long Gap Reveals
The last US-Canada cross-border technology exercise took place in 2017 under the CAUSE program. After that, the drills stopped. The reasons are not entirely clear, but the gap matters. Technology changed dramatically between 2017 and 2025. 5G networks were still in early deployment in 2017. Autonomous drone technology was far less advanced. The ACE-CASPER experiment represents a restart after years of lost momentum.
What changed to bring the two countries back to the table? One factor is the maturation of 5G. Another is the increased availability of commercial off-the-shelf drone systems that can carry sophisticated sensors. A third is the policy push from the Trump administration to prioritize domestic drone manufacturing and expand border surveillance. The combination of technical readiness and political will created the conditions for a new round of testing.
The nearly decade-long gap also means that institutional knowledge may have been lost. Personnel who worked on the CAUSE exercises have moved on. New teams on both sides of the border will need to rebuild relationships and reestablish protocols. The November tests will be as much about organizational coordination as about technology.
Commercial 5G as a Double-Edged Sword
Using commercial 5G networks for government surveillance operations has clear advantages. The infrastructure already exists in many areas. The costs are shared with civilian users. The technology is constantly upgraded by telecommunications companies competing in the marketplace. DHS does not need to build its own network from scratch.
But reliance on commercial infrastructure also creates vulnerabilities. A 5G network that works well for streaming video on a smartphone may not handle the demands of persistent surveillance. Network congestion, tower failures, and cyberattacks can all disrupt the feed. If a drone is relying on a commercial network for navigation and data transmission, a service outage could cause it to lose connectivity or crash.
There is also the question of data security. Commercial 5G networks carry traffic from millions of users. Government surveillance data traveling over the same infrastructure could be intercepted or leaked. DHS will need to implement encryption and network segmentation to protect the video feeds and sensor data. The ACE-CASPER experiment will test whether these protections are sufficient.
How Residents Can Learn About the Tests
For someone living near the US-Canada border, the November drone tests may feel like an unwelcome surprise. DHS has not announced specific locations or flight paths. The procurement documents describe the exercise in general terms without naming towns or counties. Residents who want to know if their community will be affected have a few options.
First, monitor the DHS Science and Technology Directorate website for public notices. Federal agencies typically publish environmental assessments and public comment periods before conducting large-scale tests. Second, contact local emergency management offices. County and state agencies are often informed about federal exercises that may affect their jurisdictions. Third, follow local news outlets in border communities. Reporters in these areas tend to cover federal activities closely.
Privacy advocates recommend attending public meetings if any are held. The ACE-CASPER experiment may generate questions about data retention, oversight, and the long-term use of the infrastructure. Residents have a right to ask whether the 5G towers and drone launch sites installed for the test will remain in place afterward.
The Broader Implications of Recon Drone Testing
The ACE-CASPER experiment is one piece of a larger puzzle. DHS is simultaneously expanding its counter-drone program, launching a purchasing tool for police and emergency agencies, and deploying AI-powered surveillance towers along the southern border. The November tests fit into a pattern of increasing automation and data collection at the nation’s borders.
The focus keyword for this discussion is recon drone testing, and the November experiment represents one of the most ambitious examples to date. By testing across an international border using commercial 5G networks, DHS is exploring a model that could be replicated elsewhere. If the tests succeed, similar exercises may follow along other borders or at ports of entry.
The technology itself is not inherently good or bad. Drones can save lives in search and rescue operations. They can provide situational awareness during natural disasters. But the same systems can also be used for persistent monitoring, data collection, and enforcement. The outcome depends on the policies and oversight mechanisms that govern their use.
As the November tests approach, the conversation around recon drone testing will likely intensify. Privacy advocates will push for transparency and limits on data retention. Industry vendors will compete for contracts and market share. Government agencies will focus on technical performance and operational readiness. Each of these perspectives is valid, and each will shape the future of border surveillance technology.
The ACE-CASPER experiment is not just a test of drones and 5G networks. It is a test of how the United States and Canada choose to manage their shared border in an era of autonomous systems and pervasive connectivity. The results will matter for years to come.
