AP-375 realistic Distance

What is a realistic distance for the AP-375 ? 
I was told 200m. Trying to find solid documentation on this. 

 

The area I am trying to cover is flat and open without obstructions.

Hi

The maximum distance is more depending on the client device then on the AP. And also the desired speed. With long distances the speed drops very fast.

Re: AP-375 realistic Distance

It really depends on Signal Strength.

I tried with AP-275 in Ekahau

 

At -69dbm, you can get 200m.

Tx Power on Access Point was 25mW

Re: AP-375 realistic Distance

I found the chart below. 

 

Assuming the below I would have a datarate of 216 at -71 or 108 at -76.

 

Does this sound accurate ? Any thoughts?

Re: AP-375 realistic Distance

The only caveat I see with that chart is that the MCS rates shown indicate 4 spatial streams. In an outdoor environment, 4 spatial streams may be difficult to support at range.
