RouteROS软路由 Nstreme远距离无线传输技术

不会吹牛吧？无线网络可以传送60km？
怕是在太空传送吧

呵呵。海平面有人做到300多公里

Nstreme和Nstreme2 远距离无线传输技术

这功能属于 MikroTik专有的无线协议，在长距离上有非常突出的表现，nstreme协议可以使用在三种模式中：

· Point-to-Point mode – 点对点模式通过在每一个点架设一个无线设备实现

· Dual radio Point-to-Point mode (nstreme2) – 这个协议是通过在每一个点架设两套无线设备，同时分别一对做接收和一对做发送，实现双向的通信。能做到高速连接。

· Point-to-Multipoint – 点对多点模式的客户论旬（类似AP控制的令牌环）

Nstreme 2 使用两张无线网卡一张作发送，另一张作接收。我们有客户连接距离达到60 km，并且速度达到35 Mbps在没有使用turbo mode

这是一个来至保加利亚客户的报道:
"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 wlan21.2. 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=nstreme dual slave [admin@MikroTik] > interface wireless set wlan2 mode=nstreme dual slave 1.6. Creating nstreme dual interface and setting Tx and Rx radios and frequencies:
[admin@MikroTik] > interface wireless nstreme dual add rx radio=wlan1 tx radio=wlan2 rx band=5ghz tx band=5ghz rx frequency=5180 tx frequency=53001.7. 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 nstreme dual print Flags: X disabled, R running 0 X name="nstreme1" mtu=1500 mac address=11:11:11:11:11:11 arp=enabled disable running check=no tx radio=wlan2 rx radio=wlan1 remote mac=00:00:00:00:00:00 tx band=5ghz tx frequency=5300 rx band=5ghz rx frequency=5180 rates b=1Mbps,2Mbps,5.5Mbps,11Mbpsrates a/g=6Mbps,9Mbps,12Mbps,18Mbps,24Mbps,36Mbps,48Mbps,54Mbps framer policy=none framer limit=2560
II. MikroTik Device 2
2.1. Enabling wireless cards 1 and 2:
[admin@MikroTik] > interface enable wlan1[admin@MikroTik] > interface enable wlan22.2. 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=nstreme dual slave [admin@MikroTik] > interface wireless set wlan2 mode=nstreme dual slave 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 nstreme dual add rx radio=wlan1 tx radio=wlan2 rx band=5ghz tx band=5ghz rx frequency=5300 tx frequency=5180 remote mac=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 nstreme dual print Flags: X disabled, R running 0 R name="nstreme1" mtu=1500 mac address=22:22:22:22:22:22 arp=enabled disable running check=no tx radio=wlan2 rx radio=wlan1 remote mac=11:11:11:11:11:11 tx band=5ghz tx frequency=5180 rx band=5ghz rx frequency=5300 rates b=1Mbps,2Mbps,5.5Mbps,11Mbps rates a/g=6Mbps,9Mbps,12Mbps,18Mbps,24Mbps,36Mbps,48Mbps,54Mbps framer policy=none framer limit=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 nstreme dual set nstreme1 remote mac=22:22:22:22:22:22 disabled=no
