Technical specifications for our Cloud Based Solution

Our Cloud-based remote interpretation solution uses state-of-the-art communication technology that provides high-quality sound even under poor network conditions.  A super-wideband connection with up to 12.5kHz frequency range is used, with flexible adjustments based on the available bandwidth. The sound quality we deliver is, therefore, superior to that which can be achieved with traditional remote connections.

Cloud based interpretation solution flow chart
  • ​Minimum 6 Mbps download/upload for video (2Mbps audio only) + additional 2Mbps down/up for each audio channel/language. If attendees connect through standard broadcasting equipment and radio/IR headsets, the above bandwidth is sufficient, otherwise additional capacity should be set aside for streaming to the audience.

  • When streaming to attendees through laptops, tablets or smartphones, minimum 0.5Mbps download per user is required.

  • Ping on any connected devices must be below 50ms Maximum of 20 devices per wireless access point (Wi-Fi router) 

  • When connecting the PCs of the interpreter(s) and the speaker(s), an Ethernet cable connection is required. 

  • Use mobile Speedtest app ( to test bandwidth and ping, testing several times in different places of the room 

Congress Remote Security Configurations

  • Congress Remote is built on WebRTC, a leading technology for secure real-time audio and video streaming from browsers and mobile apps.

  • Users can login with an event token or a login link. Interprefy platform is GDPR compliant and no personally identifiable data of audience is stored, but IP addresses, and type of connecting devices are logged.

  • All media streams sent through Congress Remote are encrypted using AES 128-bit encryption, and all publishing is taking place from a secure HTTPS page. The main protocols providing WebRTC security are SRTP for media traffic encryption and DTLS-SRTP for key negotiation.

  • Optional 2-Factor Authentication allows the event organiser to limit event access only to users with known phone numbers or email addresses. The list of users is added when configuring an event. After entering the login token, users will then need to enter a 4-digit code that they receive by SMS or email, depending on the event setting.
