Wireless – Multi access point setup for connecting ~150 devices(smartphones) to the same wifi local network

designlanstreamingwireless

I am trying to connect 150 smartphones (Samsung Galaxy S5) to a single wifi network, so that I can access streams from them on a computer on the LAN. What should my (multiple) access point (AP) setup be like to get the best access speed?

I need to access a file/stream from each phone whose address would be "http://192.168.1.X:8080/link" (x changes for each phone). And I cannot connect all my phones to the same wifi AP without tanking my access speeds. In what way should I configure 3 APs so my computer (also on the same network) can just see all the device ip addresses?

I found this Windows Phone video wall (http://www.youtube.com/watch?v=mcSd2xH_vS4) where they have a 14 x 14 grid of phones connected to a media server through 3 wifi APs. My use case is similar to this.

If I just daisy chain 3 APs with the first one as a master with DHCP enabled and the other two with static ips and they all have identical SSIDs, how can I control which Phone connects to which AP? (All the devices are in close proximity, and all three APs sit together about 5 feet from the installation, so its unlikely that a device is only in range of one AP)

Ideally, I want each AP connecting to a different set of 50-ish phones and I want to maintain decent enough access speeds, so that I can stream data in realtime to the computer.

Thanks for looking into my question! 🙂

A common miscomprehension when dealing with streaming is the relation between bitrate and throughput.

Meanwhile your throughput is higher than the bitrate of the stream you are, generally, OK. (ever heard about the Nyquist–Shannon sampling theorem)?

Therefore you should first of all try to stimate the bitrate of the stream and than do your estimation based on this and not on the maximum throughput of your devices.

Consider also that the worst enemy of real-time video is the jitter.

For what concern the problem of the association this is not a problem at all since each AP can broadcast an arbitrary SSID (even hidden) while referring to the same VLAN.

Of course go for the 5GHz spectrum since you will need to use, a lot, of non-overlapping channels.

I'm sorry but with my limited knowledge I can't suggest you more than this.
