Space on the ceiling where I have essentially unlimited space? I'm not saying there aren't advantages to this idea. Eg powering the APs with 120V from the light fixture would mean they can use fiber instead of PoE 2.5G ethernet. T

Oh absolutely! That's the main reason why every room needs an AP. A 20mbps 4K video only uses up 1% of the air time for wifi 6E. Any more than that will noticably increase p99 latency. A device outside the room could easily use 10x as

Why incorporated into the light fixture? I paid ~$280 for each U6 Enterprise and that's the only thing that limits how many I have. I'm sure it's the same for anyone that cares about wifi performance. How much of a premium wo

Jokes aside, I get a consistent 1600mbps over wifi 6E which is good enough for me. Of course you need an AP in every room to get consistent performance, but wifi has always been like that. And unless your applications use forward error corr
