I'd try a set of powerline modems like TP-Link TL-PA9020P to get from the wired network in the projection room to the venue space you need to transmit from.
Even in a crowded apartment building (100+ flats) mine were able to sustain ~400 Mbps between rooms. A commercial space like a cinema is unlikely to have a lot of line noise for you to contend with. -JB On Sat, Jul 31, 2021, at 12:39 AM, Karl Auer wrote: > I hope this is not inappropriate for this forum... > > We need to stream from a particular venue that has no wired access in > the space we will be streaming from.
