max transmit 10dBm

Is 10dBm the minimum max that can be configured for the Aerohive ap's? We have a lot of high density educational environments (1AP/classroom) where a max of 1 or 2 dBm would be better for the wifi environment (minimal CCI and airtime issues). I know the difference between IR and EIRP and believe the value is based on the EIRP?
Many thx for the feedback.

It does appear the lowest max power is set to 10, although I seem to recall a lower setting available in Classic.

Unless there is a way via CLI, both Classic and NG limit the max transmit power in a Radio profile to 10dB.

Now, this is the maximum power setting a radio would use via ASCP decision process, when the interface power setting is set to "auto". Of course you can always manually set the radio's power setting to any value between 1 and 20.

And in your case this would make sense anyway: Just set the power manually to 1 or 2dB. Because the only benefit you would have with being able to keep it on auto with max value to 2 would be for the radio to decided to lower the power from 2 to 1...

The more interesting question is: Are you sure you want to define such small pico-cells? If you have a high-density deployment designed for 5GHz coverage, usually the better configuration is to turn some 2.4GHz radio off (2 out of 3), and keep the power on the remaining devices at something between 5 and 10, to be measured in a site-survey.

Hope this helps.

Hi Carsten
Many thx for the feedback, I found the procedure to get it done.
About the strategy of small cells, it is a multifloor building in an educational environment with a capacity request of 25 devices (worst case smartphones). To create an airtime environment as healthy as possible we need to configure the cells as small as possible and use 2.4Ghz as good as possible (BYOD environment, so we need the 2.4GHz channel to support all devices). Offcours to minimize CCI we use the AP250 to use dual 5GHz (one DFS and one non-DFS channel) if necesarry. if we use more transmit power we have vertical signal issues because the materials between the floors atenuate the signal much less then the walls between the classrooms. Always nice to design for old buildings ;).
