Integrated vs. External Lightning Protection for LoRaWAN® Gateways: A Cost-Effective and Reliable Approach

Deploying LoRaWAN® gateways in environments likely to experience lightning strikes comes with a set of unique challenges. A reliable and cost-effective solution is essential to keep operations running smoothly without unexpected downtime or costly maintenance.

If you’re responsible for network deployment, you might have faced common issues such as:

• Complex installation processes that require specialized expertise and tools.
• Unpredictable costs related to additional components and labor.
• Concerns about system reliability during extreme weather conditions.

Choosing the right lightning protection strategy can make all the difference in ensuring long-term success.

Have you ever wondered whether integrated or external protection is the better choice?

On the first sight, integrated protection offers a simple, worry-free approach, while external protection can sometimes introduce unnecessary complexities and costs.

But is that as simple as it sounds?

During more than 15 years of supporting network operators, we’ve gained deep insights into the challenges and solutions for effective lightning protection. In this article, we’ll share our expertise to help you understand which option is best suited for your needs. Let’s start!

Integrated Protection: A Simple Approach

First, let’s focus on the integrated approach, which means having built-in protection within the gateway itself. It simplifies deployment, reduces potential failure points, and enhances system reliability.

When it comes to lightning protection, simplicity can make a big difference. Integrated solutions streamline the installation process, making it easier and more efficient. Let’s take a look at the benefits it offers.

Simplified Installation

Imagine setting up your LoRaWAN® network with minimal effort and maximum efficiency. With an integrated solution, the installation process becomes much easier. For instance, when deploying a PoE-powered TEKTELIC Macro Gateway, the steps are straightforward:

1. Mount the Macro on a bracket and attach a single ground wire. The internal grounding takes care of protection, so the ground wire placement isn’t as critical.
2. Connect Ethernet to the Macro and ensure the connection is sealed properly.
3. Mount the LoRa® antenna and cable, making sure all RF connectors are secure.

This easy setup not only saves time but also minimizes the chances of errors, ensuring a smooth deployment.

Cost-Effectiveness

Reducing costs without compromising on protection is always a priority. Gateways with built-in lightning protection eliminate the need for additional external components, cutting down on both material and labor costs. With fewer elements to install and maintain, the overall project budget can be optimized significantly.

Enhanced Reliability

Wouldn’t it be great to have a solution that works consistently, regardless of installation variations? Integrated protection ensures consistent performance because it minimizes dependency on external factors such as grounding quality and installation precision. This means fewer potential failure points and a more reliable network.

Now that we’ve covered the benefits of integrated solutions, let’s take a closer look at the challenges posed by external protection.

External Protection: A More Complicated Setup

External surge and lightning protection can seem like a good idea at first glance, but it introduces several complexities that can impact both installation and ongoing operations.

Complex Installation

Setting up external protection involves multiple components, each requiring careful installation. A typical setup might include:

1. Mounting the gateway on a bracket and attaching a ground wire with precise positioning.
2. Installing an Ethernet protector and ensuring a proper ground wire connection.
3. Running Ethernet cables between the protector and the gateway, keeping lengths short and properly sealed.
4. Installing a LoRa® protector and managing additional ground connections.
5. Securing the LoRa® antenna and cable with proper sealing.
6. Connecting cables between the gateway and the LoRa® protector.

With so many steps involved, the chances of installation errors increase, which could lead to performance issues in the long run.

Higher Costs and Lower Reliability

The additional components required for external protection not only increase costs but also introduce more potential failure points. Each added interface and connection increases the risk of failure, which can lead to unexpected downtime and higher maintenance efforts.

Now you know the pros and cons of both options, let’s dive into another important aspect – the durability and reliability of these solutions.

Durability and Reliability Considerations

Reusability of Protectors

One important aspect to consider is whether protectors can be reused after a lightning event. Modern lightning protectors are designed to absorb and divert energy efficiently, allowing them to continue functioning after minor strikes. This can help lower maintenance costs and extend the lifespan of the system.

Potential Damage in Case of Failure

However, even the best protection isn’t foolproof. If a lightning strike exceeds the protector’s capacity or if the protector fails, the gateway may suffer damage. In such cases, both the gateway and protection device might need replacement, leading to additional costs and downtime.

Why Integrated Protection Offers Greater Durability

Gateways with integrated protection tend to be more durable since they are specifically designed to work in harmony with internal components. With fewer potential failure points, the risk of damage is minimized, and the system’s lifespan is extended.

Considerations for External Protection

On the other hand, external protection systems introduce multiple components and connection points, which can increase vulnerability. Each connection represents a potential failure point, making it crucial to ensure all components are properly installed and maintained.

Conclusion

Choosing the right type of lightning protection for your LoRaWAN® gateway is important for ensuring long-term reliability and cost-effectiveness. While external protection may seem flexible, the complexities and risks associated with installation make integrated protection a more attractive choice for many deployments.
