Hello,
I just bought a RBSXTG-5HPacD-HG describes to be capable of providing data rates up to 866Mbit.
We have a radius server that generates vouchers per users with 250kb up and 300kb download... just for regular website browsing no heavy video download or gaming...
My question is if 866Mbit = 110848Kbit is correct to predict that the RBSXTG-5HPacD can handle 443 users concurrently meaning 110848kbit / 250kbit per user = 443 users ?
Thanks

Do you really mean such number as concurrently connected wifi clients transmitting their portion of data? Then no.

Not really...
Here is the real setup...
The RBSXTG-5HPacD-hg is setup as an AP on 5Ghz band...
Users have within a limited distance a dual band router connecting to the RBSXTG-5HPac as wireless client and then acting as a CPE or AP on 2.4Ghz at users level..
It looks like this





(WISP AP name Bla bla) (WISP AP client/ user AP name Da da)
RBSXTG-----------------------5Ghz------------------- Dual Band Router----------2.4Ghz------- user

wlan portion of the setup for 433 concurrent users i think will need at least 10 access-points, depending of building structure etc etc

i suggest a router on border of wlan to do traffic management
