Wireless Access

Hi Experts,

My topology using 1 IAP 215, 1 SSID, and the client access to the SSID.

The response time when I tried to ping from the client to local server in my network is around 4-5 ms, the different client reponse time is higher with 7-8 ms. Meanwhile when the same client connect to others vendor APs, the reponse time is lower.

Any one can explain for me about the expected latency of Aruba IAP?

Latency is a variable that can be introduced by other traffic, interference, client drivers and channel availability.  The difference in latency between 4-5 and 7-8 is not great, at all.

Hi CJ,

But the latency 4-5 ms is normal or high?

Have anyway to optimize latency, decrease from 4-5 ms to 1-2 ms?

Rgds,

4 to 5 is excellent. As soon as you start to add clients onto your network, the latency will go up, as a result. Up to 75 is typically okay in a more crowded environment.

Note as well that if your device is using PS (power save) polling (which we support but other vendors may not), that will create the appearance of more latency in a ping test. You can disable PSP on your client device (if it's a Windows laptop) and then retest to see if it goes down. But 4-5ms is good (I get 2.5-5ms in a near interference free environment).
