Private 5G network was used to connect cameras used in the international broadcast coverage from Edinburgh Airport
OB specialist QTV deployed a private network to connect cameras used in the international broadcast coverage from Edinburgh Airport during Queen Elizabeth II’s final departure from Scotland.
The private 5G network was designed and deployed by the University of Strathclyde and its spin-out company, Neutral Wireless Ltd, and developed through a series of proof-of-concept trials in 2022 as part of the IBC Accelerator Programme.
‘Operation Unicorn’ – the codename of the plan for handling Her Late Majesty’s death should she pass away in Scotland – saw the Queen’s coffin transported from Edinburgh Airport to RAF Northolt by air. This created the need for a high-definition, broadcast-capable, wireless solution that avoided the use of cables across the airport runway, whilst mitigating interference and guaranteeing quality of service.
The Neutral Wireless pop-up 5G SA network was deployed for QTV within 24 hours of the spectrum licence in the radio frequency band n77 (3.8GHz – 4.2GHz) being granted by Ofcom. The use of such a private 5G SA network at an airport is believed to be a first for live TV news.
The outside broadcast at Edinburgh Airport was also supported by Open Broadcast Systems and Zixi, with the former providing encoders and decoders, and latter providing licences to use the software Defined Video Platform, Zen Master Control Plane and protocol over 5G at short notice.
QTV worked closely with national broadcasters for ‘Operation Unicorn’, which provided a world feed to television channels globally, including content captured over the private 5G network.
Professor Bob Stewart, from University of Strathclyde and head of the University’s Software Defined Radio team, said: “The use of a dedicated 5G private network operating in shared spectrum licensed by Ofcom is believed to be a first for live TV news.
“A spectrum licence was granted in the n77 frequency band at Edinburgh Airport and the network was rapidly deployed on the tarmac beside the runway to provide connectivity for a wireless camera position. The network operated live and with no technical issues for nine hours.”
Jack McGill, CEO of QTV, added: “The decision to deploy such a radically new solution came about at the IBC show in Amsterdam less than 48 hours ahead of the events of September 13. Indeed, it is because of IBC’s Accelerator programme that 5G has been so robustly trialled – including our own involvement in that process – and we had every confidence that it had reached maturity for live deployment on one of the UK’s most significant ever live events.”
Gareth Gordon, CTO at QTV, explained: “Due to the scale of the production in Scotland - and indeed the whole of the United Kingdom - technical resources were stretched beyond capacity. This small but significant site was left without any traditional RF systems for positions that could not be cabled. The situation demanded new and innovative technological thinking to achieve the expectations of the production.
“From the band of the Royal Regiment of Scotland to the RAF’s C-17 Globemaster taking off and carrying Her Late Majesty The Queen from Scotland for the last time, these were breath-taking live pictures broadcast globally from the airport tarmac. The video link on the 5G network wasn’t there as a back-up – it was a live feed to the world.”
Cameron Speirs, chief commercial officer at Neutral Wireless, concluded: “It is genuinely innovative technology, pioneered in Scotland, and it was because of IBC Media Accelerator Programme that we had the proven use cases and dialogue with all the right industry expertise to make it a reality.”
