Ok, the computing will bring back the 3dB loss occurred in the slant to linear case (C5 to A5c with H+V antena).
Can I now make the conclusion that when a normal H+V CPE is used, we don’t have the 3dB loss out of miss-polarisation so we actually gain an extra 3dB in comparison to a same dBi C5?
The whitepapers make some statements but based upon slant to linear (C5 to A5c) and H+V/slant to circular.
But how is the math working in reverse setup? So A5c with 2x2 sector (only two of the streams used) that connects to 2x2 H+V standard mimo CPE?
The reason for asking is when working in ‘interop’ mode that is in-avoidable in migration (or even permanent use to avoid the extra inversion for that little bit extra performance (GPS/tdma)).
If I would have a similar gain 3rd party CPE would it achieve same signals as the C5? No matter what its polarisation is?
This is not taken in respect the slant setup will give some extra noise reduction at CPE since most other Wifi signal are predominantly HV orientated.
The extra noise reduction can be achieved by 3rd party too in fitting these in slant setup.
