Wireless Router and AP For Business

this is a continuance of this question:http://www.experts-exchange.com/Networking/Wireless/Q_28496104.html

Current setup is a Windows Server 2008 with DHCP role
Only one consumer quality Linksys wireless router

So I am to design and install a wireless network. Total devices on the network at any given time can be around 350-450 tablets, laptops, and smartphones.

How will I get IP addresses to all devices? Should I use the server DHCP with Access Points? Should I buy two business class routers each with a static ip handing out different ranges of addresses? I'm just not sure how to tackle the 254 ip address DHCP limit.

You can setup a Wifi network with a /23 or Subnet Mask

the router may have a limit, but dhcp doesn't have a limit you have to define the limit yourself, so you may have to add your own dhcp server role and not use the one provided by the router.

Your biggest problem will be congestion so you should have 3 access points one on channel 1, one on channel 6 and the last on channel 11 these access points should be wired to the router/switch.  It would be best to hire a wireless specialist to do a site survey and discuss with you what service levels you want the users to have.

350 to 400 tablets can be dealt with as David Johnson suggests by using frequency division (i.e. using different channels to split up the load).  As well, you can use spatial division by using the same frequency bands in different locations such that they don't interfere too much or at all.  This technique is being used in very-high density locations like sports arenas.  "Cells" are created with highly directional antennas; imagine narrow beams that are spatially separated and point in the same direction.  The beams are spatially in parallel so they don't interfere even while at the same frequency.
Less likely to be robust / easy to design/ would be spatial division by trying to use low power per "cell" so the coverage is limited.

Fortunately having multiple access points and antennas provides the capability to use different subnets.  This will keep the broadcast traffic down to reasonable levels.  Some advocate /24 as being best for this.  But you might get away with /23 or /22 even depending on the actual traffic levels.

Whether DHCP is centered on the server or is provided by the access points is a matter of preference.  Generally it's best to have but a single DHCP server PER SUBNET.
