MIMO vs SISO 8km urban link

Thu Sep 09, 2021 4:57 pm

i need advice,
on a 8km semi-urban link (center of the city till village-house) , is it better to have MIMO with weaker signal ( 2 x SXT 16dBi) or SISO with stronger signal (1 x SXTsq 5+ 23dBi SISO antenna with metal 5HPn)?
needed bandwidth is minimum 15mbit.
or maybe SXT + disc5 ?

the "AP" side must be an sxt because of size limitations on that specific spot + it's the same colour as the concrete behind it.
i'll be shooting into the "wild" where only 2G signal is present. AP height ~45m, CPE height ~15m.

With 8km distance, attenuation of signal will be high enough that SISO with much better antenna (7 dBi difference in gain) will more than compensate lack of MIMO.
