Short term project -- 5Ghz-only WLAN/LAN

[jp.ward16]

I've been tasked with a project -- create a small 5Ghz-only WLAN/LAN for use within a convention booth space.

The design uses one of the router Ethernet ports for connection to the dedicated Ethernet bandwidth input provided by the convention center using IP unnumbered. Then setting up STP to avoid L2 loops, a few SSIDs mapped to a DHCP server, and basic routing between the networks. I am wondering if there will be a problem with this design. It's for less than a week. There past attempts used an Airport extreme and non-cisco equipment. Does anyone forsee any issues with this setup? 

This setup is:

1x 2911 ISG2 ios 15.4 w/ 2x EHWIC-D-8ESG (8-port Ethernet switch)

1x 2504 WLAN controller

2x 3702e with 4x hi-gain antennas with POE injectors

6x SG100-16 -small business unmanaged switches (96-ports)

Windows Server 2012 R2 (for Network Services (DNS/DHCP/domain & speciality apps)

There will be less than 250 users between the switch ports and the SSIDs.

I would think more than 100 connection per AP is too much (2AP for 250 users) , I would consider at least 4-5 APs considering those user numbers

OK, thanks for the information. I went back to the planning committee to ask, and they narrowed it down to 50 WLAN users, so I am believing that 2 WAP (3702e) should be able to cover it.

[Rasika Nayanajith]

Yes, for 50 users 2 AP should be fine.

What are the users on the WLAN actually doing? The APs themselves can handle a couple hundred client associations without problem, the issues come with bandwidth and airtime usage. That said, with the count down to 50, unless you are doing some bandwidth heavy applications you're probably be fine.

You probably want to have the WLAN users on a separate VLAN from the wired clients, if that's not already what you were planning. If you just bridge the wired and wireless networks you're going to use a lot of your airtime with the broadcasts from the wired clients.

Otherwise the parts list seems reasonable. The details of the configuration are where the real trouble lies...
