4 to 600 people connecting to wifi

Need 400 to 600 people to be able to access wifi. I was going to use ubiquiti access points but I understand each unit can handle about 40 connections. How do I accomplish this?

The unifi access points have a hard limit of 127 users but recommend no more than 40. So I would need more than 10 access points to balance the load for 600.

That is the nature of the beast you need many access points to handle the load

So I am correct in my thinking?

What about IP address? A typical DHCP server will issue about 245 IP address right?

@CNL83, a DHCP server can handle any address space it is allowed to...
So if you need ~2 Billion address use 1.0.0.0 & 128.0.0.0 address & netmask ( & 128.0.0.0/128.0.0.0 for the other half of the internet)...
[ 0.0.0.0/24 ] cannot be used....   for less amount of addresses (and a usable environment): 172.16.0.0/22) should suffice.

So the amount of addresses in a Typical DHCP server only depends on the network range used...

400-600 concurrent?
What bandwidth requirements per client?
How big is the space?
5GHz only or do you need 2.4GHz too?

Craig, im sure not everyone will be using their phones all at the same time, but they all need to have access to the internet via wifi. The building is big enough to house 4 to 600 people. Im not worried about 5GHZ, I was thinking 2.4 would be my priority because it has better range.

Noci, im not sure what you mean by
& 128.0.0.0/128.0.0.0 for the other half of the internet)...

I'd only use 2.4GHz if you can't use 5GHz.  It'll allow you to use 802.11ac which will mean more clients per AP, especially if they have low-bandwidth requirements.

If you were to use 7-8 APs with 802.11ac you could easily cater for 400-600 clients if they're just web browsing.

I meant that you can setup DHCP to provide the complete Internet address range if you like, except for the 0.0.0.0/24  block. And you may expect weird things with addresses above 240.0... (As those are Multicast/Experimental) that was in response to the claim of "only 254" addresses.

You MAY want to provide a unified experience, then be sure 802.11r is supported and you may also want (  802.11k, 802.11v

To be honest I'd never let one AP get anywhere near that populated.
