The Hidden Strength Behind Every Signal

When people talk about telecoms, they think of 5G, fibre optics, or signal strength. But few outside the industry ever think about the structure holding it all up, or the minds behind it. Every time you use your phone for a call, a video meeting, or sending a message – there’s a telecom tower or rooftop structure making that connection possible.

Behind that structure is a structural engineer, quietly doing the calculations, designing the foundations, and making sure every bolt and bracket can carry the load. You may never see them, but they are the silent force keeping modern communication standing tall – because no matter how fast the technology evolves, the physical structures must remain stable.

The truth is that most people only notice engineering when something goes wrong. But for structural engineers in telecoms, the job is to make sure it never gets to that point – as long as we’re working with the right information. From wind loads on coastal towers to soft ground in challenging areas, we anticipate issues before they become failures.

As telecoms expands into smart cities, denser networks, and nationwide 5G, telecoms structural engineers are playing a bigger role than ever, ensuring that the physical infrastructure can keep up with the digital pace. From tripods to stub towers, we’re designing the platforms that connect communities, power innovation, and close the digital divide.

At KA Engineering Group, we work behind the scenes to design the structures that keep tomorrow’s networks standing– from remote tower bases to rooftop mounts, ensuring strength, safety, and resilience in a fast-moving digital world.

Beyond Blueprints: Making Telecom Structures Comprehensible Through Visualisations

Modern telecom structures, like cell towers and antennas, are incredibly complex. They are not just steel and concrete, they are dynamic systems built to handle strong winds and house sophisticated equipment. Understanding their detailed designs, predicting how they will behave, and managing them over time is a huge challenge. Visualisation software aims to simplify these tasks for telecom structural engineers.

Traditional methods, like flat 2D drawings, often fall short. There is a certain amount of information lost as they can hide how parts fit together, miss potential issues, and make it hard to see the overall view of design choices. This is where advanced visualisation software step in. They take huge amounts of technical data and turn them into interactive visual models; making complex information clear and actionable.

These tools allow engineers to see accurate 3D models of structures. More importantly, they can overlay crucial data directly onto the visual model. This means seeing where stress points are, how the tower might bend in a storm, or even tracking its maintenance history. This visual context helps engineers quickly spot issues and make better design choices, creating a shared understanding and making it easier for design teams, clients, and construction crews to work together satisfactorily.

Ultimately, clear visualisation directly impacts the entire life of a telecom structure. It leads to more informed designs, faster project approvals, and better management over time. At KA Engineering Group, we leverage advanced visualisation techniques to ensure the integrity, efficiency, and safety of critical telecom infrastructure projects.

Supporting the Solar Shift, One Roof at a Time

As solar energy continues to gain traction, more rooftops are being transformed into mini power stations. But beneath every successful solar installation lies a crucial step that often goes unnoticed: structural calculations.

Before a single panel is mounted, it’s essential to understand how the added loads, both dead and live loads will interact with the existing roof structure. Factors like wind uplift, roof slope, and roof material all play a role in ensuring long-term safety and performance.

At KAEG, we’ve recently started working closely with solar installation teams to provide structural assessments tailored to these unique challenges. Whether it’s a residential bungalow or a commercial flat roof, we help verify that the structure can safely support the system—or recommend reinforcements where needed.

It’s an exciting evolution of our work in structural design, and one we’re proud to be a part of. Because in the transition to clean energy, every detail matters, and that includes what’s holding it all up.

Strengthening existing telecommunication lattice towers using fibre reinforced polymers (FRP)

The increasing sizes of telecommunication antennas mean increasing load demands on existing towers. In many cases strengthening of existing towers is unavoidable. The common strengthening method of introducing additional members has some significant disadvantages such as weight and the windage area increase. An alternative strengthening method being investigated is the strengthening of tower legs or braces using Carbon Fibre Reinforced Polymer (CFRP).

The term is used to describe a fibre reinforced composite material that uses fibres as the primary structural component and thermosetting resins such as epoxy, polyester, or vinyl ester as the matrix.

Some advantages of this strengthening method include:

  • negligible increase of the reference wind area and therefore of the wind forces,
  • marginal increase in structural self-weight,
  • no need for exchange of brace profiles,
  • adjustment and fine tuning of the extent of strengthening to the design needs
  • great strength to corrosion and fatigue.

Some advantages of this strengthening method include:

  • A totally brittle failure. It has no plastic behavior, so it has not the ability to absorb energy
  • Anisotropic response and strength. There are many variables that could change its behavior and strength. The grade and quality of materials, the manufacturing process, fiber architecture, and the quality need to be considered.

It will certainly be interesting to see if this technology is adopted within the telecoms industry.

KAEG has the capability to accurately engineer complex and challenging telecom structures, including providing cost effective workable strengthening schemes aimed at improving structural capacity and life-extension.

The Impact of Telecom Tower Deflection on Signal Quality

In our modern communication, where our interconnected world relies on seamless signal transmission, telecom towers are the unsung heroes of our digital age, enabling the flow of data that keeps us connected. At the heart of this reliability lies the structural integrity of telecom towers, which bear the weight of antennas and facilitate the transmission of signals across a wide range. However, when these towers sway and bend under the forces of nature, such as wind and temperature fluctuations, a critical issue arises. Telecom tower deflection, the subtle yet impactful bending and swaying of structures due to environmental forces, can significantly affect signal quality. Hence, precise antenna alignment becomes crucial for optimal signal transmission. Any deviation caused by deflection may lead to signal misdirection and degradation. Therefore, striking a balance between flexibility and stability in tower design is paramount to maintaining structural integrity and preserving signal quality.

Engineers employ various techniques to mitigate tower deflection and preserve signal integrity. Common approaches include using guy wires for additional support and stability, as well as implementing structural reinforcements to strengthen key components of the tower. However, implementing these strategies requires careful consideration of cost-effectiveness and practicality. Studies show how deflection affects signal quality across environments, guiding design, and maintenance practices. Additionally, advancements in materials, predictive modelling, and remote monitoring offer promising avenues to enhance tower performance and minimise signal disruption, ensuring reliable communication networks for our interconnected world.

At KAEG, we recognise the importance of telecom tower deflection on signal quality, highlighting the complex relationship between engineering, nature, and connectivity. We prioritise this understanding, acknowledging the need for effective mitigation strategies to ensure the reliability and integrity of our telecommunications infrastructure. As we look to the future, continued innovation and collaboration will be crucial in navigating the ever-changing landscape of signal transmission.

Streamlining Telecom Structure Surveys with Lidar Technology

In the realm of telecom infrastructure development, precision and efficiency are paramount. Traditional methods of surveying telecom structures have undergone a revolutionary transformation with the advent of Lidar technology. Lidar, which stands for Light Detection and Ranging, utilises laser beams to measure distances and create detailed 3D models of objects and environments. While previously used primarily in specialised equipment, recent advancements have seen Lidar technology integrated into consumer devices, such as smartphones. Lidar, integrated into smartphones like recent iPhone models, enables capturing precise 3D models of objects.

Gone are the days of cumbersome on-site visits with dedicated cameras or expensive drones. With Lidar-equipped smartphones, surveyors can quickly capture intricate details of structures from a distance. The ability to generate detailed 3D models allows designers to gain a comprehensive understanding of the existing structure, eliminating the need to sift through countless photos, and hoping the surveyor did not miss a crucial angle or having to rely on guesswork.

Lidar technology in smartphones offers a cost-effective and accessible solution for surveying. Surveyors can efficiently capture and analyse data, reducing time and expenses. Portable and versatile, these devices adapt to various environments, from remote cell towers to urban infrastructure.

In conclusion, Lidar technology in smartphones streamlines surveying, enhances accuracy, and provides valuable insights into existing structures. As technology advances, further innovations will revolutionise telecom infrastructure development, making surveying tasks more efficient than ever.

Bamboo to Replace Telecom Steel?

Assuming that we can keep the Pandas at bay, should we be looking at replacing steel with bamboo? Can bamboo telecommunication towers be sustainable and economical? Telecom towers are usually fabricated using steel because steel has very good strength. However, due to its tightly packed fibres, bamboo has superior tensile strength over steel. Producing steel also has a lot of drawbacks like high costs, atmospheric pollution, and environmental degradation. Bamboo, on the other hand, can be produced at very low costs and has various environmental benefits.

So far so good! Unfortunately, tensile strength alone is not sufficient. Bamboo is prone to insect attacks and will degrade until sustained exposure to water which is an issue for any towers not installed in the Sahara!

Perhaps the future of bamboo will depend on its use as a composite material or more resistant strains will be cultivated to remove some of the limitations. Either way, we are excited to see what the future holds.

At KA Engineering Group, we like to think of ourselves as a solution independent structural consultancy. We leverage our extensive engineering experience to accurately design the most suitable telecom structure for your needs.

Impact of Feeder Arrangement

Feeder cables can FAIL a lattice tower, through exceeding the structural utilisation capacity, if not arranged thoughtfully. Carefully planned feeder arrangement in a simple system can reduce the utilisation of the lattice tower legs by 15% and reduce the tower brace utilisation by nearly 40%!

Without adequate forethought, a telecommunication system with 16 feeder cables on a tower may be arranged in stacks of 1 or 2. This leads to wind load across eight, or even 16 feeder surface areas.

We investigated the effect of feeder arrangements on tower utilisation. We placed four antennas at the top of an existing 30m square lattice tower, fed by 16 typical sized feeders in a variety of different arrangements. To replicate a common tower arrangement, the structure also included a ladder mounted on one of the tower faces.

What We Found

Our analyses showed the maximum tower utilisation with the feeders stacked in a single row of 16, mounted on one leg, adjacent to the ladder location. Minimum utilisation was from feeders stacked in rows of four, mounted on a leg that is not directly supporting the ladder.

The difference in structural utilisation between these two scenarios was 15% for the tower legs, and 38% for the tower braces!

A surprising find was the structural utilisation from the feeders separated into groups of four, stacked in rows of two, mounted on each leg. The leg and brace utilisation were greater than those in the minimum scenario by 5% and 6% respectively.

Take Away Message

Feeders must be arranged with tower loading in mind. With less loading from feeders, more ancillaries can be placed on the tower, resulting in a more useful AND more financially profitable structure.

Check your existing towers. Check your proposed towers. Think about how the feeders are, or are proposed to be, arranged:

  • Are the feeders helping to distribute the loads more evenly throughout the tower?
  • Are the feeders stacked in the most efficient manner to reduce wind load on the structure?
