Case Study: How a Top Energy Infrastructure Firm Overcame Field Connectivity Issues with Horizon’s DG505G Dongles

Client overview

How a Top Energy Infrastructure Firm Overcame Field Connectivity Issues with Horizon’s DG505G Dongles is demonstrated through the experience of an international construction and engineering company that deals in energy infrastructure. The firm incurred connectivity issues in a recent Texas refinery project. They are known to construct intricate facilities such as oil refineries, LNG terminals, and petrochemical complexes. The company typically operates in harsh environments where communications are mission-critical. They require rapid and secure field connectivity to enhance productivity and safety for their operations.

Challenge: Patchy Wi-Fi in a Mission-critical setting

The company used a private CBRS network to create secure wireless coverage within the area where the construction activity took place. The Wi-Fi coverage was patchy in certain areas, which meant that field engineers and safety staff using laptops and iPads were unable to secure an uninterrupted connection. These vulnerabilities hindered real-time data exchange, added delays to incident reporting, and added unforeseen risk to employees in dead spots of the facility.

Solution: Horizon DG505G – Uninterrupted plug-and-play 5G coverage

To address the problem, Horizon Powered collaborated with the company to arm their field teams with the DG505G 5G USB-C Dongle. The dongle is small, driverless, and designed for quick deployment, making it an effortless solution.

Why DG505G was the solution:

• Plug-and-Play Ease – No setup or drivers needed
• Device Agnostic – Compatible with Windows, iPadOS, MacOS, ChromeOS, and Linux
• CBRS-Ready – Compatible with n48/B48 bands for integration into their private network
• Portable – Compact and lightweight, simple to transport in the field

The dongles, with nano-SIMs loaded, were inserted into field devices and connected instantly. In mere seconds, users had robust, high-speed connections—no technical support required.

Results: Real-time communication, safer operations

The DG505G units bridged the coverage holes throughout the site. Field crew personnel enjoyed uninterrupted, secure connectivity to the private network, allowing them to:

1. Share schematics and reports in real-time
2. Make VoIP calls to co-workers throughout the zone
3. Receive operations and safety notifications in a timely manner.

The result was a quicker, safer, and more collaborative field environment. Communication delays were removed, and timely updates passed freely between teams, ensuring project schedules and on-site safety standards.
