  • 1.  Max-Min TX Power Question

    Posted Jul 21, 2020 01:08 PM

    Hello guys and gals... I received a question from a very important customer today and I'm not exactly sure how to answer it. Unfortunately I don't have the luxury of ignoring this question (LOL) and I have to come up with a response that will satisy them. I've done a couple of hours of Google research with no luck. Hopefully you guys can help me out. Here is the question.

     

    In our WiFi configuration, we have TX max = 6 and TX min = 3.  How does that work in practice as far as users being able to detect the network and login (if allowed)? Is the TX power always 3 but then can go up to 6 if a user is already logged in and the WiFi controller detects an issue with connectivity to that device?

     

    To provide some context, this is a very small network that is confined to a space of approximately 100 ft x 12 ft. The network consists of an Aruba 7010 controller and 2 Aruba JW165A APs. Any help would be GREATLY appreciated! Thanks!

    The Aruba system can change the transmit power of an access point dyanmically based on RF conditions throughout the day.  The max and min TX power define what the range of transmit power will be constrained to when those changes are made. The AP might use the maximum power if there is little cochannel interference (6) , and less power if there is cochannel interference.  Cochannel interference would be more prevalent on the 2.4ghz or "g" band.
