short wireless PTP link - max throughput

Hi All,

Haven’t used the mikrotik gear before - so please be nice with these newbie questions.

I’ve done some searching and reading, and are a little confused.

Basically got a client with 2 offices 300m apart with clear LOS, and they need max throughput for file transfers etc.

I’m thinking this hardware.

2x Mikrotik 433ah boards
2x Radios (2.4ghz or 5.8ghz)

I understand 802.11n radio’s aren’t available yet so I guess I’m hoping for 54meg connection. In real terms, what method is the best way to get max throughput. Do I need dual radios / dual antennas at each end and use nstreme. Or use turbo mode ?

Cheers
Peter.

Using a 433 AH and 5Ghz Turbo will get you around 25 - 30 Mbps TCP Possibly a little more ( From a 532 A to a 333 on 5.8 Turbo I get 24Mbit TCP, and about 37 UDP)
I have not tried Nstream Dual, but you should have the same speeds in both directions then.

Depending what you need the link for, and what kind of bandwidth you need, you might want to go N streme dual with 4 radio’s and 4 antenna’s. After all the cost difference is only two wireless cards, and two antennas since the board supports 3 wireless cards already.

If you just want to do internet sharing, and some file sharing, just use turbo mode. I have two media Center extenders over my WLAN, 5 Km’s over the first link, and there is a media extender there, then that is connected via WDS to another AP that has another media extender, and they both work for live tv with no problems, at about 7 - 8 Mbit each.

Quite a cost investment to share a cable tv connection eh? Oh, figured we would share the internet too while the infrastructure was there :slight_smile:

Expect to get at least 40 Mbps TCP in turbo mode. Some say you can get 60 to 70 Mbps.

If you can’t get about 60mb TCP from 5Ghz Turbo then you have interference or other issue even with 411 and good 5Ghz card. You can get 35MB TCP from 20Mhz channels and 411 board.

BobcatGuy’s numbers are about half what is possible with that gear…
