The Effect of Enabled Probe Suppression in a MACRO/Micro Cell Architecture of Cisco AP3802I

[t.matsudo]

We had an experimental study in our indoor office environment to confirm the effect of enabled Probe Suppression in a Micro cell on a MACRO cell architecture of Cisco AP3802I in dual 5GHz band operations [1].

It was found that the enabled Probe Suppression makes the number of client terminals balanced between in the MACRO cell and in the Micro cell as adaptively as possible.

Since it can be expected that the Micro cell on the MACRO cell architecture for Cisco AP3802I and AP2802I creates double the capacity within the boundaries of a single cell of a single AP, we should enable the function of Probe Suppression when we operate the Micro cell on MACRO cell architecture.

[1]Our report of the experimental study has been opened to the public at <https://www.netone.co.jp/report/column/column1/20190227.html> since Feb.27, 2019.

In the report, you can see real world use of the probe suppression, not in a laboratory use of it.

Thanks a lot for your study, this is really interesting to know.

Hi, patoberli (Collaborator) ,
Thank you very much for your comment and giving 5 stars of helpful !

On page53 in Cisco's document  at <https://www.cisco.com/c/dam/en/us/products/collateral/wireless/nb-06-wireless-wifi-starts-here-ebook-cte-en.pdf>,

we can find "Cisco has also developed innovative techniques to steer the clients between
microcells and macrocells.".

In our report, you can see real world use of the innovative techniques (probe suppression).

We are glad if the report contributes to you !.

Awesome!

Hi,  Ric Beeching,

Thank you for your comment!

Probe suppression = band select?

Hi, Brian Taylor,
Thank you for your comment!

The probe suppression supported by Cisco AP3802I and AP2802I is not a band select that uses 2.4GHz band or 5GHz band.

The probe suppression is used in dual 5GHz band operations.

Both a micro cell and a MACRO cell in a single AP use 5GHz band.
