If you’ve ever glanced at a digital screen while waiting for a bus or checking train schedules, you might not realize how much technology is behind that simple display. A reliable connection keeps these vital informational tools running smoothly, making our daily commutes easier and more organized.

A Partnership for Reliable Connectivity

ZetaDisplay, a prominent player in the digital signage world, originated back in 1999 as Pronto TV. Today, it is recognized as one of the largest digital signage providers in Europe. This growth was fueled by a strong partnership with Com4, a Nordic connectivity network designed specifically for high-reliability needs.

ZetaDisplay’s journey has been noteworthy. Its very first client, the Oslo Airport Express Train, still partners with them today, showcasing an impressive commitment to service. The company operates across eight nations, with a dedicated workforce of about 270 employees. Its notable clients in Norway include various transport authorities and businesses, ensuring ZetaDisplay’s screens reach city dwellers and tourists alike.

Com4 understands the unique challenges presented by the Nordic environment. With harsh weather and spread-out infrastructure, their network provides essential, reliable connectivity that ensures digital signs remain functional even in the toughest conditions.

Navigating the Connectivity Challenges

For ZetaDisplay, maintaining uptime is not just a goal; it’s their entire promise to clients. If a screen goes dark, not only is information lost, but customer trust can also diminish. The challenge lies in deploying screens where traditional fixed lines simply can’t reach, such as remote bus stops or outdoor spaces.

In many of these locations, local Wi-Fi isn’t secure enough for the critical data that must be displayed. Older 2G technologies can only manage text, which fails to meet current standards that require rich visuals and real-time updates. Additionally, the need for robust security measures complicates the implementation even further. Com4 serves a regulated market, which demands strict security protocols to protect sensitive data.

A Cellular Solution to Digital Signage

ZetaDisplay has smartly opted for Com4’s cellular connectivity to address these challenges. By using SIM cards in places where Wi-Fi or fiber isn’t feasible, they create a secure, always-on connection between their displays and their cloud-based management system. Each display setup includes a PC paired with a 4G modem, alongside environmental sensors that monitor conditions like temperature and humidity.

This innovative approach allows for real-time updates. For example, public transport agency Ruter can feed live GPS data directly to screens, ensuring that commuters receive timely information. This capability proved especially crucial during the pandemic when immediate updates on health guidelines were necessary.

With secure connections established by Com4, ZetaDisplay can troubleshoot and make updates remotely, eliminating the need for on-site visits. These measures maintain system security and efficiency, a necessity when managing countless devices spread across different locations.

Improving Sustainability and Future Innovations

The benefits of reliable connectivity extend beyond operational efficiency; they also promote sustainability. Remote management capabilities reduce the need for site visits, which lowers the carbon footprint associated with transport and installations. This means that crucial public infrastructure can function optimally while also being eco-friendly.

Looking ahead, ZetaDisplay is considering the integration of eSIM technology. Such advancements would not only improve the reliability of their connections but also increase flexibility in managing their devices across diverse environments. By ensuring consistent communication, they aim to reduce errors and improve overall control.
