Hello, everyone.
Regarding High Client density, is using a multi-cell design (one AP broadcasts multiple cells, say one for 2.4, one for 5 and one for 6 GHz) also a good solution to handle a lot of clients? Or broadcast the same SSID but on different channels.
Also, channel bonding isn’t really useful in high density scenarios, or is it? Sure, you can transmit on more frequencies and have a higher throughput but when we’re talking about a high density deployment, we aren’t only concerned about the throughput but also about the reliability or the general air and channel utilization.
If you have a few devices, then sure, channel bonding can help. But if you have 200 of them, they will all crowd the space and compete for airtime. If a device does get its turn then sure, it can transmit a massive amount of data but only for whatever its time duration is during its turn. Not to mention that not everyone has to transmit a lot of data.
The point that I thought about above also reduces the amount of channels that you can use which could be useful in a high density deployment.
It feels like it all boils down to many different things. We need coverage, we need a good speed/throughput, we need the density to be distributed so all clients have equivalent access to the channel, it gets pretty complex.
//Edit: Without getting too deep into this, is OFDM the opposite of channel bonding in a way? Channel bonding combines channels to achieve a higher frequency range therefore there is more throughput. OFDM takes those 20 MHz and divides them into subcarriers. Then, for example, your wireless devices could get a slice of the channel without interfering with the rest. So you divide a channel, get less throughput, but support more stations at the same time.
Or is this OFDMA? 
Thank you.
