How to Run an International Event Without Interpretation Booths or Receivers

• Every time a multilingual event is planned, someone has to find floor space for bulky interpretation booths and then rent, hand out, collect, and chase down hundreds of receiver units.
• "Boothless" AI real-time interpretation — where attendees scan a QR code and listen on their own smartphone — is quickly becoming the new default for events.
• This article compares the traditional hardware-centric setup with the smartphone-based approach on method, cost, and day-of operations, so you can set a clear standard for your own events.

"We've signed the venue contract, but there isn't enough space for the interpretation booths. What now?"

"If an attendee loses a receiver, who covers the replacement cost?"

These are the two questions we hear most often from PCOs and corporate event leads heading into an international conference or seminar. Interpretation booths and FM receivers — long treated as non-negotiable for multilingual events — are reliable, but they bring heavy setup costs, hard physical constraints, and a serious drain on staff time spent distributing and recovering equipment.

The alternative that has risen quickly to address those limits is BYOD (Bring Your Own Device) AI real-time interpretation, which turns each attendee's own device into the receiver. This article covers how the technology removes booths and receivers, how it compares with physical equipment, and how to decide whether it fits your event.

🔍 How receiver-free interpretation works

The core idea is simple: the attendee's own smartphone and earbuds become the interpretation equipment. It runs in a web browser with no app to install, and gives on-site and remote attendees the same experience.

No queues to hand out receivers, and no scramble after the event to track down missing units — which cuts the on-site staff workload dramatically.

🆚 Comparison: receiver-based vs. receiver-free AI interpretation

Here is the traditional hardware build and the modern mobile/AI approach side by side, from an operations point of view.

Receiver-free interpretation removes the physical constraints outright. That is exactly why it is becoming the standard for corporate events, where floor space and budget are the tightest constraints.

✅ The practical call: choose by venue and purpose

Receiver-free interpretation wins decisively on cost and operations, but it is not the right answer for 100% of events. The decision should follow the nature of the event and how comfortable your attendees are with their devices.

Drop the booths and receivers and go with AI interpretation when you're running:

• Multilingual corporate seminars and town halls: internal or partner audiences where getting information across quickly and efficiently is the priority
• Large trade shows and open-stage sessions: open floor plans where a booth cannot be built and attendees come and go continuously
• Overseas factory tours and site visits: listening while walking, where carrying heavy equipment is impractical

Stay with the traditional booth-and-receiver setup when you're running:

• Government summits and strictly confidential sessions: events where personal phones are prohibited or all outside network access must be cut
• Events for a predominantly elderly audience: where most attendees would struggle with a smartphone or Bluetooth earbuds

❓ Frequently asked questions

Q. What if attendees don't bring earbuds?

A. Keep a small stock of inexpensive wired earbuds and USB-C adapters at the information desk for anyone who forgets. It is far cheaper than renting dedicated receivers that cost hundreds of dollars a unit to replace.

Q. Will interpretation still work if venue Wi-Fi is unreliable?

A. Audio and text streaming needs far less bandwidth than video, and works comfortably over ordinary LTE/5G. For halls packing in thousands of people, the usual precautions still apply: request a mobile base station from the carrier, or build dedicated event Wi-Fi.

Q. How much delay is there between the speaker and the translated audio?

A. It varies with the system and network, but current AI interpretation typically delivers translated audio in roughly 1–2 seconds. That is faster than a human interpreter's EVS (ear-voice span) of 2–4 seconds, so the back-and-forth of a live conversation and the flow of a talk stay intact.

Q. Does everyone have to install an app?

A. No. It uses WebRTC: scanning the QR code with the phone's built-in camera opens a mobile browser and interpretation starts immediately — no app install.
