routeros Nstreme遠距離無線傳輸技術

Nstreme和Nstreme2 遠距離無線傳輸技術
這功能屬於 MikroTik專有的無線協議，在長距離上有非常突出的表現，nstreme協議可以使用在三種模式中：
·         Point-to-Point mode – 點對點模式通過在每一個點架設一個無線設備實現
·         Dual radio Point-to-Point mode (nstreme2) – 這個協議是通過在每一個點架設兩套無線設備，同時分別一對做接收和一對做發送，實現雙向的通信。能做到高速連接。
·         Point-to-Multipoint – 點對多點模式的客戶論旬（類似AP控制的令牌環）
Nstreme 2 使用兩張無線網卡一張作發送，另一張作接收。我們有客戶連接距離達到60 km，並且速度達到35 Mbps在沒有使用turbo mode
這是一個來至保加利亞客戶的報道:
"65 km, AR5213, 37 Mbit with n-streme (TCP test), We're using 2.4 GHz proccesors or better, 5GHz-turbo mode"
Nstreme dual Step-by-Step
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
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
