for Real-time data like audio and video, Jitter (the physical time difference between the arrival of packets) is also a serious consideration when it comes to performance.
If you really need consistent performance, but have to be wireless, you should avoid anything wireless running on ISM (unlicensed) bands.Įdit: I should also note: Latency isn't the only technical issue in play. (Microwaves often leak radiation in the 2.4ghz band, which can kill wifi performance - they're a fairly common cause of "wifi sucks in the building during breaktime/lunchtime/whatever" complaints). Or when someone in concessions turns on a microwave. Multiply by 50 audience members, and suddenly you've added 150 end-nodes competing for wireless bandwidth in a very limited spectrum (5.8's a little better, but 2.4ghz has a tendency to be a real mess.) You might have really clean performance on a set of Wifi-powered IEM's, only to have that performance go to hell when you pack a room full of people, because each audience member is carrying a mobile phone, which is beaconing on 2.4ghz for wifi, 5.8ghz for wifi, and 2.4ghz (again) for bluetooth. It's more accurate to say that Wifi performance is non-deterministic and highly dependant on the local environment at the time of use. r/broadcastengineering - Broadcast EngineeringĪlso wifi is inherently laggy and does not allow low enough latency that would be needed for monitoring.r/projection_mapping - Projection Mapping.You might find these other subreddits useful:
