Azimuth vs Open Air method

[comer]

Hi All,

I found charts are very helpful in determining the practical value of a particular device for me. However, it is quite confusing when sometimes devices that I compare have been tested using different methods. What's more confusing is that test results are very different for the same device being tested using different methods.

For example, for WNDR3300: Azimuth 2.4Ghz Down average 49.4, Open Air - 14.7 (Az/Oa = 3.36). DIR-655: Azimuth 2.4Ghz Down average 50.5, Open Air - 28.9 (Az/Oa = 1.75).

Is it at all possible to compare the results/charts based on these methods? Is there some kind of consistency, a rule perhaps how to compare the results?

Regards,
comer

Unfortunately, there is no way to directly relate the two methods. How To: Converting Path Loss to Distance can help give you a feel for actual coverage from the Azimuth data.http://www.smallnetbuilder.com/content/view/30124/98/
