For many things, local wifi is sufficient. But home (a.k.a "cheap") wifi never solved the duplex problem, did it?

When I have people trying to multitask (videoconferencing while sharing their screen with too many microphones still online and maybe backups running in the background), it often seems like bandwidth is the choke point. People try to do too much over wifi, not realizing that they're taking turns in half-duplex with the frequency.
