What is a good rule of thumb in deploying Wireless A/P in regards to concurrent users per

From our experience and research it appears to be 15-20

How do we factor the use of smartphones that are obviously part of the challenge

    What type of APs are you using? But generally speaking, I would tend to agree with your numbers. Also, while smartphones are something to take into account, I would say that only a subset of power users would be the most likely to try using them ofn the wifi (especially with unlimited data plans getting killed off). And even then, those tend to get used in place of a laptop. So I would maybe add 5-10% to the expected number of users on wireless.

    Throughput requirements are a factor here too.  If you want to use the wireless connection for high-bandwidth applications you should probably allow no more than 10-12 clients per radio, per AP.  If you have a dual-band AP it may have 2 radios, so 2 radios x 12 users = 24 clients max.)

    On the other hand if you want to just use the link for general web browsing you could allow more clients if the bandwidth requirements are relatively low in comparison.

    If clients are using smartphones too, I'd create a different SSID/VLAN for that which could attach to a different QoS profile.  This would allow me to prioritise legitimate LAN traffic whilst still allowing some bandwidth for smartphones only if it is available.

    Thanks for the incite
