60 Km setup help!

RouterOS General
1

Hi! MT OS master guys out there!
i"am gathering all necessary for a 60 Km PtP link with LOS available.
I 'planning to use Ntreme for this set up and i’am a little stress about what could be the ideal hadrware platform for this set up (CPU, Mainboard…)
More over i need three wireless interfaces on each nstreme bridge ; 2 for Ntreme and 1 for an other PtP link so that each of my ntreme bridge can serve as repeater like this:

Stand-PTP-Brdg1 |— (5Km)connected to—|PTP-Brdg+Nstreme-PtP-Brdg1
|----- (60KM)tconnected to—|Nstreme-PtP-Brdg2+PTP-Brdg
|-----(5Km)tconnected to--------| Stand-PTP-Brdg2

Hope this is clear

So plan also to user 30 Dbi for Ntsreme links and 23 Dbi for 5km Link.

So please tell me does this config sound good? and any experience please that i coul learn from will be very appreciated.
Thanks!!

Recommendation for long range point to point links

Wow that’s a long one!
Use the highest gain antennas you can get for sure.
Have not used them but consider the new 400mW miniPCI Atheros radios from Ubiquiti - Mikrotik are going to be selling them and apparently they work well.
You will need Nstreme running I think. If so, you need a more powerful CPU as Nstreme overhead is significant.
What throughput are you expecting?
Not sure what realistic link budget you get at that distance - is it over water, or what? Clear Fresnel zone?
5km should be easy, 23dBi flat panels would be my choice.

on 2.4 ghz you may use 200mw senao or similar( i use zcom 200mw 5212 and california 24dbm antennas), do not use boosters..

I’d use the 400mW Ubiquiti they come in 2.4 and 5.8 and are based on the Atheros chipset..

Prism cards lack some of the features available in MTOS, unlike Atheros.

Sergio, I have links to 80 Km PtP.

Use: Routerboard 230 outdoor with Atheros, nstreme and 24 dBi grid antennas. With a good instalation, this link is for 5 Mbps TCP throughput

The Prism (Senao) card, is only for link of 20 Km max.

Very interessting msolis . could you tel me more about your system config please ; like polling enable or not and which manufacturer antenna?

This is the nstreme configuration 0 name=“pv” enable-nstreme=yes enable-polling=yes framer-policy=exact-size
framer-limit=3200

This is the quality signal:

status: connected-to-ess
band: 2.4ghz-b
frequency: 2452
tx-rate: 11Mbps
rx-rate: 11Mbps
ssid: rancho-pv
bssid: 00:0B:6B:30:2E:14
radio-name: pv
signal-strength: -76
tx-signal-strength: -81
tx-ccq: 23
rx-ccq: 25
wds-link: no
nstreme: yes
polling: yes
framing-mode: none
routeros-version: 2.8.26
last-ip: 192.168.5.138
– [Q quit|D dump|C-z pause]

This is with Hyperlink antenas.

I have another link to 97 km, same antenas, and routerboard 230 outdoor at 2 Mbps TCP.

97km!!!

I think you deserve a “Mikrotik Hero” award … well impressed!
Never heard of anyone doing better than that -

Thanks. This is the result of a excellent human equipment and a excellent Mikrotik product

just one word: FANTASTICO !! :smiley:
you seem to have the best link all over the world !!
I’am more calm now about my 60 Km link :slight_smile:
But one thing ; what do you exactly mean about “well set up link” is there somethink should i take in count other than good antenna alignement?
thank you

These are some ingredients:

1.Much experience or much persistence.
2.Two work parties (one in layer point).
3. Maps and compass.
4. Good antennas.
5. Short cable from antenna to radio.
6. Mikrotik + Atheros.
7. Don´t amplifier.
8. LOS and Fresnel zone.
9. Don´t satured wireless area.

Good Luck.
