Hello All.

I have a project about a link 7km, I Require 20mbps real or more.

Can someone give me an advice about what equipments need ??????????? I Think about 433ah with ubiquiti SR2.



Thanks for all.

Regards.

Hey,


I recomend use of 5Ghz (802.11a) cards, like R52 or SR5.

There are more powerfull cards, like R52H or XR5 but you dont need them for a 7Km link.

Right configured this hardware will offer something like 25Mbps aggregated or more.

cya

for 7km you can use any radio card like cm9 or R52 with 13dBm. It will work, and a 27-30dBi antenna for 5Ghz.

how about 18Km and need 20Mbps?

Can someone give me an advice about what equipments need?

We have tested the distance only 9.8KM with clear LOS and 100% tx/tx ccq, data rate is 54*2/52*2

When doing the tcp test it's can up to 45Mbps.

But, when you inject the real internet traffic, it's only can upto 25Mbps (in + out) with good ping latency (<5ms) but sometimes it's will jump to 50ms for few then back to normal.

Thus, i would suggest, do not trust full with the devices speed test, but with the real intranet or internet traffic then only you will get the actual result.

hi, last days i start a link 17km
tested from pc to rb433ah ,udp test show 28mbits, and tcp 20mbits procesor show 100% busy
to get more speed i have do test from pc to pc and i need wireless card with turbo ,
used hardware : one end rb600 23db card 5gh 32db antena ,other end rb433ah 23db antena 18db wireless card.
signal rx/tx -73/-67 ccq 70/95%
nstream wds enabled,
conection : ap bridge < station wds
i have problem to find free chanel , about half of available chanels i can't estabilish conection or speed is wery low ,but 5300mhz is working fine.
in future i change both cards to r52n or to ub5 (ub5 have turbo mode and 23db) and i get more then 40mbits pc to pc bandwidth.
