Safer, Smarter Telecom Tower Inspections with Drones

Cellular phones have become an indispensable and unavoidable part of our modern lives. From work and communication to navigation and entertainment, they play a crucial role in how we function each day.

To support the millions of cell phone users in South Africa, thousands of telecommunications towers have been constructed across the country. These towers form the invisible web that keeps us all connected.

Why Tower Inspections Are Crucial

A single tower often supports the antennas of multiple cellular companies, making it a critical piece of infrastructure. It’s essential for tower owners to:

• Determine available space for hardware upgrades
• Monitor the condition of the structure
• Check the maintenance state of communication equipment

Any malfunction or structural issue could result in major disruptions, leaving thousands in the area without cellular service—a scenario that’s not just inconvenient, but potentially dangerous in emergency situations.

The Traditional Approach: Climbing Crews

Until recently, the only way to assess the condition of a telecom tower was to send up a climbing crew. While effective, this method comes with significant challenges:

• Requires extensive risk assessments
• Demands specialised safety gear and training
• Involves technicians working at height, often in harsh weather conditions
• Takes time and coordination, delaying decision-making

This traditional approach puts human lives at risk and often delivers only a partial understanding of the tower’s condition.

A New Way Forward: Drone-Powered Inspections

One of the largest cellular providers in South Africa approached us with a challenge: inspect three of their towers quickly, accurately, and—above all—safely.

At Darkwing Aerials, we’re always pushing for innovation. We set out to transform the inspection process using advanced drone technology.

Our Equipment: Precision Tools for the Job

We deployed two of our most trusted aerial platforms:

• DJI Mavic Pro 2 – Compact, agile, and excellent for close-range detail
• DJI M300 Enterprise – Our industrial workhorse, built for heavy-duty inspections

Using these drones, our team captured high-resolution images and video of each tower from multiple angles. The level of detail was unmatched by traditional inspection methods.

From Drone Imagery to Digital Twins

The captured imagery was handed over to our 3D drafting specialist, who used it to build digital twins of the towers. These digital models provide our client with a fully interactive and up-to-date 3D representation of each structure.

With the digital twin, clients can:

• Measure antenna height, tilt, and azimuth
• Calculate available mounting space for new equipment
• Pinpoint areas of wear or damage on the structure
• Keep a historical record for future reference and maintenance planning

The Benefits: Speed, Safety, and Accuracy

By using drones, we were able to:

- Complete all inspections in record time
- Gather more comprehensive and accurate data
- Eliminate the need for human climbs, drastically improving safety

What once took days and posed safety risks can now be done in a matter of hours, with zero danger to technicians.

A Glimpse Into the Future of Infrastructure Maintenance

This project demonstrates how drone technology is changing the way we manage and maintain critical infrastructure. With tools like the DJI M300 and digital twins, we’re able to offer:

• Smarter decision-making for tower upgrades
• Improved operational efficiency
• Greater peace of mind for telecom providers and their customers

At Darkwing Aerials, we’re proud to be leading the way in safe, innovative, and data-driven inspection solutions. Whether you're managing cellular towers, energy infrastructure, or industrial facilities—we’re here to help you see it all, safely from the sky.
