SVi Digital uses Perle IRG Routers to Enable Outdoor Digital Transit Advertising

PRINCETON, N.J. - Jan. 8, 2026 - PRLog -- In a groundbreaking innovation for the advertising industry, SVi Digital has successfully tested the first real-time digital out-of-home (DOOH) ads on moving transit buses, using Perle IRG Cellular Routers.

For decades, bus-side advertising has relied on static posters. That's changing. Bright, dynamic digital screens can now display ads that update in real time as buses travel their routes. This advancement, using unique and patented screen technology, opens the door to powerful contextual advertising, where ads can adapt instantly to time, weather, traffic, or location.

The Connectivity Challenge
Streaming high-resolution ads to moving vehicles demands a rugged, secure, and reliable connectivity backbone. Transit environments are harsh, with constant vibration, rough terrain, and fluctuating network conditions.

SVi Digital chose Perle IRG 5G Routers, designed for automotive and transportation deployments, for their durability and advanced security features:

• High-speed 5G with 4G LTE fallback for seamless streaming
• MIL-STD-810G shock and vibration resistance and IP54-rated aluminum housing for durability
• Advanced security with over 30 features, including VPN support and encryption
• Integrated GPS for real-time location tracking

"At Perle, we believe connectivity should never come with hidden costs. Our IRG Cellular Routers include all features, security updates, and software enhancements without annual subscription or license fees."
— John Feeney, COO, Perle Systems

Proven Results
In a proof-of-concept deployment (https://www.perle.com/applications_solutions/transportati...), buses in Belfast have been streaming ads from a central production facility in London without interruption since 2023. Although the technology is sophisticated, the setup is simple. Ads are streamed over a cellular network to an IRG 5G Router on a bus. The router connects via an Ethernet port to a micro-PC, which connects to digital screens on the bus exterior.

"Routers are obviously a key part of the whole communications package. As far as the IRG 5G Routers are concerned, they've been stable from day one. No complaints whatsoever. A gold star."
—Graham Slane, Founder & CEO of SVi Digital

This marks a significant milestone for DOOH advertising, paving the way for scalable, sustainable, and highly targeted campaigns on public transit worldwide.
