India's Border Industries Face New Threats: Can a Multi-Layered Approach Ensure Survival?

India's border industries are facing a new and growing threat: the increasing use of drones by adversaries. These unmanned aerial systems can be used for a range of malicious activities, from reconnaissance to sabotage, and have already been employed in several recent conflicts.

The threat is particularly acute for industries operating in sensitive border regions, where the risk of drone attacks is highest. However, instead of relying on anti-drone jammers, experts recommend a multi-layered approach that combines passive detection technologies, physical protection measures, and close coordination with government agencies.

One of the primary advantages of this approach is that it avoids the regulatory challenges associated with active electronic countermeasures. In India, the use of wireless signal jammers is tightly regulated by the Department of Telecommunications, and private companies are generally prohibited from operating such systems.

Moreover, modern drone jammers do not selectively block hostile unmanned aircraft alone. Depending on their design and operating frequencies, they may also interfere with nearby mobile networks, Wi-Fi communications, satellite navigation receivers, or other authorised radio services. In densely populated industrial areas, indiscriminate jamming could disrupt legitimate civilian and emergency communications.

In addition to regulatory challenges, there are also operational considerations to take into account. During a military crisis, the Indian Armed Forces would likely establish coordinated electronic warfare environments along sensitive border sectors. Military counter-drone systems operate within carefully managed electromagnetic plans that seek to minimise interference with friendly communications, surveillance systems, and air defence networks.

Uncoordinated civilian jamming could complicate this environment, potentially degrading situational awareness during critical operations. Therefore, it is essential for industries to focus on building resilience rather than solely defeating drones.

In this context, passive drone detection systems emerge as a highly effective option. Unlike active jammers, these systems simply monitor the environment for drone activity without transmitting disruptive signals. Modern systems combine radio-frequency monitoring, acoustic sensors, electro-optical cameras, and thermal imaging to identify, classify, and track small unmanned aircraft approaching a facility.

Physical protection offers another valuable layer of defence. Experience from recent conflicts has demonstrated that relatively simple measures such as reinforced roofing, protective barriers, and anti-drone netting can significantly reduce the effectiveness of small first-person-view (FPV) drones and loitering munitions against exposed equipment.

Close coordination with government agencies is equally important. Industrial facilities located near sensitive border regions can establish communication channels with local civil administration, police, and security authorities. Rapid reporting of suspicious aerial activity enables authorised agencies to assess the situation and, where necessary, employ government-operated counter-drone systems.

Timely information sharing can substantially improve overall situational awareness while ensuring that any active response remains under authorised operational control. Business continuity planning should also receive greater attention, focusing on recovery and resilience rather than solely defeating drones.

In conclusion, India's border industries face a new and growing threat from drones. However, by adopting a multi-layered approach that combines passive detection technologies, physical protection measures, and close coordination with government agencies, they can stay safe and secure in the face of this new threat. By taking a proactive stance, India's border industries can build resilience and ensure their survival in the face of this new threat.
