In Spring 2018 a venue hosting Noel Gallagher and his High Flying Birds used Halo to help keep their 9,300 attendees safe.
Halo performed fantastically well, with no drop of signal or loss or slowing down of service.
Images of ejected persons were circulated in realtime, the radio was kept free for urgent use as non-critical/routine incidents were dealt with via Halo, whereas they are otherwise lost due to more urgent business and as a whole the feedback was fantastic.
