Background The BBC hosts a number of public events every year. September 2018 Background The BBC hosts a number of public events every year. The events include 500 – 1000 people; Studio audience or premiere screenings 4,000 people; 6 Music Festival 9,000 people; Teen Awards 25,000 people; Radio One’s Big Weekend Hitoshi Morioka, SRC Software

Contents Distribution for Waiting Audiences September 2018 Contents Distribution for Waiting Audiences Audiences are typically made to arrive early and queue with little or no entertainment. For example; in 2017 the BBC ran a number of Doctor Who Christmas Special Premieres at various fringe locations around the North of England. These venues tended to have few facilities. One such venue was a disused cinema. The queuing fans would gain considerable benefit from being able to watch previous Doctor Who episodes or new exclusive content. As there are no existing facilities at these events a cheap and easy to rig Wi-Fi system would mean there would be no need for large screens and related logistics. Hitoshi Morioka, SRC Software

Program Monitoring for Staffs September 2018 Program Monitoring for Staffs Radio One’s Big Weekend is the most ticketed free music event in Europe. There are typically 2,000‑3,000 backstage staff who are required to watch induction videos. They normally crowd around screens and watch the videos in batches. A system that could deliver the induction videos to people’s personal devices would mean no rigging of screens and allow more people to watch the video at a time. Saving both time and money. Many people at large events need program feeds. These could be performers in dressing rooms or technical staff in backstage areas. Typically, this is done by rigging SDI feeds to monitors. This is expensive and inflexible. A Wi-Fi based system would allow people to monitor on their own devices, reducing costs, reducing rigging time and allowing the selection of multiple feeds.

Providing Additional Values at Festivals September 2018 Providing Additional Values at Festivals Enable a ‘virtual drive-in-movie’ Deploy in limited area near charging facilities to provide video content for festival goers. At large festivals there are often simultaneous stages or it’s impossible to get between stages promptly. Live streaming of video feed from simultaneous events/multiple stages would provide access to performances that festival goers might miss. Hitoshi Morioka, SRC Software

Broadcast Wi-Fi Trials September 2018 Broadcast Wi-Fi Trials Edinburgh Festival in 2017 3 evenings 3 APs Consumer grade 2.4GHz and 5GHz 130 STAs Smart phone App for the trial 2 streams of contents https://www.bbc.co.uk/rd/blog/2017-11-broadcast-wi-fi-trials Hitoshi Morioka, SRC Software

Problems Association limits per AP September 2018 Problems Association limits per AP Limited to 2,007 by the specifications. (limit of the length of the TIM element) Practically, limited to a few hundred for better user experience. Some devices fell into sleep mode inappropriately. It depends on hardware / OS. Failed to receive beacons (TIM)? Implementation issue? Some devices switch between APs / stuck on a low signal strength AP inappropriately. Implementation issue? (e.g. AP selection algorithm, background scan...) The L2 security enhancement is a must as it'll protect users from malign packets. Hitoshi Morioka, SRC Software
