Dual radio Point-to-Point mode Nstreme 2

These are MikroTik proprietary wireless protocols to achieve outstanding performance on a very long range links. Regular wireless links will have large time delays for data traveling on a long distances, with Nstreme you do not have to worry about this anymore.
Nstreme2 goes even further by using two wireless cards in each end - one for transmit and one for receive.

Our customers have links of 40 km (Line of Sight) and speed of 35 Mbps without turbo mode (20Mhz channel). Up to 70MBps in turbo mode.

To make this setup, you can use:

* Two RB433AH or similiar power device
* Four Atheros PCI wireless cards with pigtails (
* 2 Mars antennas (they are two antennas, however inside of each antenna there are two antennas,
one Vertical the other Horizontal Polarisation. Using this kind of antenna will save a lot of space on the mast,
also will decrease the noise, as there are just short pigtails from wireless card straight to antenna connector which is 10cm away)

This is high performance link, devices suitable can be found in high performance section.

Nstreme dual Step-by-Step howto:

Here is a step-by-step explanation how to enable nstreme dual on a fresh installed MikroTik devices:

I. MikroTik Device 1

1.1. Enabling wireless cards 1 and 2:

[admin@MikroTik] > interface enable wlan1 [admin@MikroTik] > interface enable wlan2

1.2. Assigning IP address to the ethernet interface:

[admin@MikroTik] > ip address add address=192.168.1.1/24 interface=ether1 [admin@MikroTik]> ip address add address = 192.168.1.1/24 interface = ether1

1.3. Creating bridge interface:
[admin@MikroTik] > interface bridge add

1.4. Adding ethernet interface to the bridge interface:

[admin@MikroTik] > interface bridge port add interface=ether1 bridge=bridge1

1.5. Setting wireless cards 1 and 2 to nstreme mode:
[admin@MikroTik] > interface wireless set wlan1 mode=nstremedualslave
[admin@MikroTik] > interface wireless set wlan2 mode=nstremedualslave

1.6. Creating nstreme dual interface and setting Tx and Rx radios and frequencies:
[admin@MikroTik] > interface wireless nstremedual add rxradio=wlan1 txradio=wlan2 rxband=5ghz txband=5ghz rxfrequency=5180 txfrequency=5300

1.7. Adding nstreme interface to the bridge:

[admin@MikroTik] > interface bridge port add interface=nstreme1 bridge=bridge1

1.8. Checking the MAC address of the nstreme interface (in this example: 11:11:11:11:11:11):

[admin@MikroTik] > interface wireless nstremedual print Flags: X disabled, R running 0 X name="nstreme1"
mtu=1500 macaddress=11:11:11:11:11:11 arp=enabled disablerunningcheck=no txradio=wlan2 rxradio=wlan1
remotemac=00:00:00:00:00:00 txband=5ghz txfrequency=5300 rxband=5ghz rxfrequency=5180 ratesb=1Mbps,2Mbps,5.5Mbps,11Mbps ratesa/g=6Mbps,9Mbps,12Mbps,18Mbps,24Mbps,36Mbps,48Mbps,54Mbps framerpolicy=none framerlimit=2560

II. MikroTik Device 2

2.1. Enabling wireless cards 1 and 2:
[admin@MikroTik] > interface enable wlan1
[admin@MikroTik] > interface enable wlan2

2.2. Assigning IP address to the ethernet interface:

[admin@MikroTik] > ip address add address=192.168.1.2/24 interface=ether1

2.3. Creating bridge interface:

[admin@MikroTik] > interface bridge add

2.4. Adding ethernet interface to the bridge interface:

[admin@MikroTik] > interface bridge port add interface=ether1 bridge=bridge1

2.5. Setting wireless cards 1 and 2 to nstreme mode:

[admin@MikroTik] > interface wireless set wlan1 mode=nstremedualslave [admin@MikroTik] > interface wireless set wlan2 mode=nstremedualslave

2.6. Creating Nstreme dual interface and setting Tx and Rx radios and frequencies and setting the MAC address
of the remote nstreme interface (in this example: 11:11:11:11:11:11 [step 1.8]):

[admin@MikroTik] > interface wireless nstremedual add rxradio=wlan1 txradio=wlan2 rxband=5ghz txband=5ghz rxfrequency=5300 txfrequency=5180 remotemac=11:11:11:11:11:11 disabled=no

2.7. Adding nstreme interface to the bridge:

[admin@MikroTik] > interface bridge port add interface=nstreme1 bridge=bridge1

2.8. Checking the MAC address of the nstreme interface (in this example: 22:22:22:22:22:22):

[admin@MikroTik] > interface wireless nstremedual print
Flags: X disabled, R running 0 R name="nstreme1" mtu=1500 macaddress=22:22:22:22:22:22
arp=enabled disablerunningcheck=no txradio=wlan2 rxradio=wlan1 remotemac=11:11:11:11:11:11
txband=5ghz txfrequency=5180 rxband=5ghz rxfrequency=5300 ratesb=1Mbps,2Mbps,5.5Mbps,11Mbps ratesa/g=6Mbps,9Mbps,12Mbps,18Mbps,24Mbps,36Mbps,48Mbps,54Mbps framerpolicy=none framerlimit=2560

III. MikroTik Device 1

1.9. Setting the MAC address of the remote nstreme interface (in this example: 22:22:22:22:22:22 [step 2.8]):

[admin@MikroTik] > interface wireless nstremedual set nstreme1 remotemac=22:22:22:22:22:22 disabled=no
