What kind of internet connection do I need for digital signage?
Bandwidth basics
Digital signage mostly downloads content, so download speed matters more than upload. For simple images and text, 5 Mbps per screen is fine. If you're streaming HD video or using video walls, plan for 15–25 Mbps per screen. Upload speed matters when you're sending logs or uploading new content from the screen, but 1–2 Mbps is typically sufficient.
Most signage players buffer content locally, so they don't need a constant high-speed connection. They can download new playlists in the background and keep playing if the internet drops. However, live data (like weather, news, or social media feeds) requires a steady connection.
- Check your current speed at fast.com or speedtest.net.
- Wired Ethernet is more reliable than Wi-Fi for fixed installations.
- If using Wi-Fi, ensure strong signal at each screen location.
- Consider a separate network or VLAN for signage to avoid congestion.
Reliability and data caps
Reliability is more important than raw speed. A connection that drops frequently will cause screens to show outdated content or error messages. If your business internet is unreliable, look into a 4G/5G backup router. Data caps can also be an issue: streaming video 24/7 can use hundreds of gigabytes per month. Check with your ISP if you have a cap.
For a single screen showing static images, you might use less than 10 GB per month. For multiple screens with video, it could exceed 500 GB. Many signage platforms let you schedule downloads during off-peak hours to save bandwidth.
Common mistakes
- Assuming you need gigabit internet—most signage runs fine on basic broadband.
- Relying on public Wi-Fi, which is often unstable and insecure.
- Ignoring data caps and getting charged overage fees for streaming video.
