Mixing Single and Dual Chain Clients on the same AP?

Just curious how and if it affects throughput on a Dual Chain N AP if you have both Single and Dual Chain N clients associated to the AP. Will the dual chain clients still see dual chain speeds or will the single chain clients slow everything down?

Well

example

your dual chain client has to spend 1s to transmit same aount of data as 2s single chain client.


Single chain client will slow overal maximum throuput, but dual chain clients will still work
