WiFi network size - is broadcast traffic an issue?

Hello,

it is a common design goal for wired networks not to create too large broadcast domains. As a rule of thumb I once learned not to exceed 1.000 hosts (or /22 network) at maximum.

What I would like to know is: does this also apply to wireless networks and to what extend? What happens if let's say a /24 network that is used for wireless clients is beefed up to a /23? So does that broadcast domain problem apply to wireless networks or is it even worse having for the mentioned scenario?

Thanks in advance!
