Live Captioning Mobile World Live – Increasing content reach and engagement for MWC, the largest connectivity event in the world  

Mobile World Live is the award-winning broadcast service of Mobile World Congress (MWC) and home to GSMA event keynote presentations. This is the global mobile industry’s premier destination for news, insight and intelligence.

Since 2015, Red Bee Media has been providing live captions for Mobile World Live to more than 80,000 event attendees throughout the event online at, and on up to 30,000 screens around the venue and in hotels around the city. 

In the first year, back in 2015, the live captions were produced at the show, but since 2016 Red Bee Media delivered the service remotely from our broadcast operation center in London.

"We were delighted to once again work with Red Bee Media. Our content coverage is bigger every year. Supporting almost 45 hours of TV content remotely - much of it live and involving complex technical language - is a challenging task, but Red Bee has always been delivering with very high levels of accuracy. ”
