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!!

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.
Regards

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

tx-signal-strength: -81
tx-ccq: 23
rx-ccq: 25

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.
