My report[1] tells you the experimental results of the performance of Cisco ClientLink supported on Cisco Aironet access points. You can remember the great performance of ClientLink forever. I have learned that new access points for IEEE802.11ax are Cisco Catalyst 9100 access points. I have also learned that only transmit beamforming specified by 11ax is in the new access points and that Cisco ClientLink is no longer supported on them. Since we and our many customers have been helped very much by Cisco ClientLink, I would like to express my appreciation to Cisco ClientLink in the report.

My report[1] tells you a simple viewpoint to understand the evolution of the wireless LAN from 1997 to the 2020s. You can also get basic knowledge on an uplink of Wi-Fi6, the latest IEEE 802.11ax standard. Data analysis results based on our experimental study in an indoor office environment using Cisco AP3802I operating in 5 GHz band will help you to understand the basic knowledge on the uplink of Wi-Fi6. To operate uplink multi-user(UL-MU) transmission properly in Wi-Fi6, each signal power received from client terminals at one AP should be equal. Therefore, each client terminal performs Transmission Power Control (TPC) to reduce each transmission power. I believe firmly that wireless terminal manufacturers will have a good collaboration with Cisco to have a good performance for UL-MU transmission in Wi-Fi6.

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. ... View more
