For digital signage on a trade show booth, you count 5–10 Mbps per Full HD screen (H.264, compressed video) and 15–25 Mbps per 4K screen with H.264 streaming. If you use H.265/HEVC, that drops to 12–16 Mbps per 4K displaySo, with four 4K screens on a single Wi-Fi connection, you need at least 50–65 Mbps of dedicated bandwidth — excluding laptops, tablets, and visitor traffic on the network.
Why exhibition halls are dangerous for WiFi
An exhibition floor is a radio minefield. Hundreds of exhibitors transmit simultaneously on the 2,4 GHz and 5 GHz frequencies. Bluetooth equipment, wireless microphones, and LED screens can interfere with the 2,4 GHz band. This means that the nominal speed of the hall network is rarely available for your stand.
The rule of thumb: never assume a shared network for critical display content. Always request a dedicated business network or arrange your own 4G/5G connection as a backup. At larger events — more than 100 participants or stands — additional infrastructure is almost always necessary.
Bandwidth calculator per scenario
Below you will find concrete target figures per configuration. The figures are based on streamed video (no locally stored content). For locally stored files on the display itself, the required bandwidth for playback is zero — only updates via the CMS count in that case.
| Configuration | Resolution | Codec | Bandwidth per screen | Total (4 screens) |
|---|---|---|---|---|
| Static images + simple animations | HD (1080p) | H.264 | 2–4Mbps | 8–16Mbps |
| Full video content | HD (1080p) | H.264 | 5–10Mbps | 20–40Mbps |
| Full video content | HD (1080p) | H.265 | 2,5–5Mbps | 10–20Mbps |
| Full video content | 4K (UHD) | H.264 | 25–35Mbps | 100–140Mbps |
| Full video content | 4K (UHD) | H.265 | 12–16Mbps | 48–64Mbps |
Always add 30% margin for peak load and CMS synchronizations. Four 4K screens with H.265 therefore require a connection of at least in practice. 80–85Mbps dedicated.
H.264 vs. H.265: the codec determines your required line
The codec is the biggest variable in your bandwidth calculation. H.265 (HEVC) delivers a reduction of 40–50% compared to H.264 for the same image quality. For 4K streaming, this concretely means: H.264 requires 25–35 Mbps per stream, while H.265 does the same for 12–16 Mbps.
The downside: H.265 requires more processing power from the media player. Older or budget Android devices may stutter during HEVC decoding. Therefore, always check whether your displays hardware-support H.265 before configuring your content workflow accordingly.
Advice: Start with H.264 if you are unsure of the decoder capacity of your screens. Switch to H.265 as soon as you know that all displays can handle it — then you halve your bandwidth requirement in one step.
Local storage: the most reliable solution
Streaming depends on the connection. At a trade fair, that connection is unpredictable. The most robust approach is content. upload to the display in advance and local playback. The display then only requires bandwidth for CMS updates and remote management — that is typically 1–5 Mbps per screen, even with 4K content.
All PixioDisplays run on an integrated Android computer (Android 13/14) and store content locally via USB or the PixioApp. At the Summit edition, Pixio Display deployed more than 50 PixioDisplays at a single event — it was precisely the local storage that eliminated central network dependency and kept the content synchronized across all screens.
For a Rent an exhibition stand display or purchase: always ask about the CMS options and whether local storage is included by default when making a request.
Dedicated network or 4G/5G: when do you choose which?
A fixed connection provided by the exhibition organizer is stable but expensive and sometimes slow due to shared usage. Your own 4G/5G router gives you full control over bandwidth and is independent of the hall network. Preferably use a router that connects to multiple providers simultaneously — this reduces the risk of outages.
Set your displays to a separate SSID or VLAN, separated from visitor traffic and POS systems. This way, you reserve the available bandwidth entirely for your screens and prevent a busy booth from disrupting your content display.
With the PixioDisplay Mobile (43″ touchscreen, €1.795 purchase or €175 rental per day — price list Q2 2026), the integrated Android computer is standard. You do not need a separate media player or laptop, which further reduces the load on the network: one IP address per screen instead of two devices per display.
Checklist for the day of the trade fair
- Measure the actual speed at the stand location before setup, not in the aisles.
- Reserve your own 4G/5G router as a backup, even if the hall offers WiFi.
- Use 5 GHz instead of 2,4 GHz — less interference from other exhibitors.
- Upload content locally before start; stream only if really necessary.
- Calculate your bandwidth based on the number of screens × Mbps per screen + 30% margin.
- Separate networks: displays on their own SSID, visitors on a separate network.
