Hi i want to create script to do some actions after checking lte interface network mode For example if "gsm,3g,lte" is checked do /beep but it does't work correctly.but i don't know why ? :global a /interface lte print once do={ :set a $network-mode } :if ($a = "gsm,3g,lte") do={...

Hello, I am trying to use mini-pci 3G modem(Sierra MC8775) via baseBox5 but it doesn't work and I don't know what cause this problem. Board model: RB912UAG-5HPND 3G Modem model:Sierra MC8775 Link status looks like "established" in the beginning of connection but after status change to &quo...

Hi all 8) thnx 4 all reply recent change and result : reduce tx power by all rate fix=18 to ~ 43 signal NV2 isn't good for me ... TX signal from AP when running bw test very unstable ( -40 > -85 !!!!! ) why ?!?!?!!? Nstreme is realy great ... CCQ is always 100/100 ... P troughput ~ 605000 kbps .... ...

Hi,

I have used UBNT Rocket AC with NetMetal AC.
Are you saying you have RocketAC on one side of the link and Netmetal on the other?

i think he said :
CCR ______ NetMetal5+RocketAC Dish <........12KM ........>Rocket AC Dish+Netmetal __________ CCR

seanet

Unless something has changed, CCQ doesn't quite work the same on NV2 as it does on 802.11 and Nstreme. CCQ on NV2 seems to be an average, not a real time display. I'll change an AP, see CCQ in the single digits and still get full bandwidth. I'll check it later and CCQ is 90+ %. after 10 min CCQ go ...

Yes try to lover signals to ~-45dbm , as suggested. using all rates fixed it should be optimal signal strength for best AC wireless performance also nv2 is working grate on some links on some it doesn't it depends one environment. i try to all rate fix = 18 NV2 isn't work great for me ... signal st...

seanet

I dont think nv2 is not optimized for AC, people here are using it with success, including me. You have something wrong. Did you try to change the interface queues and test which one works best with nv2? Did you try to run the bw test between the 911s? What is the throughput when set to 40MHz inste...

Can you share with me more info about your 802.11 config mode. AP Bridge. 5GHz only AC. Prot:- 802.11 Datarate: uncheck all supported and basic. VHT left default. Under Nstream :- Enable polling and disable CSMA selected. Best fit 4000 frame limit. Tx power:- all rate fix 17. Remote: Station bridge...

Your signal is too high, lower the power to get -50. I have AC link running on 40MHz channel NV2 with SNR 55dB and is working very well. Link can be fully utilized with 1 TCP connection, max aggregate throughput around 200Mb, latency with full load is 2-3ms, CCQ between 90-99%. This is with x86 dua...

seanet

Use nv2.
Nv2 isn't optimized for AC....
Really?

yes...any idea?

seanet

just change mode to 802.11

You can use an crystal globe or you can show us the configuration of the wireless . Your choice. Status might help also. interface=wlan1 radio-name="PTP-AP" mac-address=4C:5E:0C:6F:49:2F ap=yes wds=no bridge=no rx-rate="650Mbps-80MHz/2S/SGI" tx-rate="650Mbps-80MHz/2S/SGI&qu...

hi all :D i try to setup two link with NV2 protocol / Link 1:transmit data(100mbps TCP) & Link 2:rec data (100mbps TCP) [ "100mbps tcp full duplex" ]/ but i don't know how? low cpu usage on 433GL is important devices on Popsite1 : 433GL + 2*Dbii F50N-Pro + 2* Arc wireless Dual Polar Di...

The most important item is transmit ccq ... try to highest CCQ ( 100% ) in RX / TX

With my experience
better throughput when :
ُ50 < signal < 60
45< SNR < 65
tx power @ 1.2 km = 17dBm
UDP throughput (sextant to sextant) = 160 - 205 mbps

seanet

high TX power = destruction and Reflection ==> Low throughput
Try to reduce or increase tx power to have better throughput (MT UDP bwtest) ! Not higher SNR

seanet

HI all
thnx For Reply to this post

SNR = Signal - noise
More signal = More Tx power + FLOS

I think reliable SNR is >>> 45 < SNR < 65

High SNR ? > Reduce tx power
low SNR ? > increase Tx Power , Try to FLOS , Change Freq to find better signal

@ hipro5
i think 65 dB Signal to noise is the best result for 1.2 km link with 17db tx power !

seanet

@ semakka

speed test result From AP to CPE
UDP ( transmit ) : 139 mbps
TCP (Transmit ) : 37 mbps
TCP ( Both ) : 17 /18

@ Lakis :
it's simple p2p link ( wireless Mode :Bridge - station Bridge ) /// bridgh port > wlan1-ether1

nstreme !!!? Nooo ...
plz post nstreme configuration (wireless mode - security and etc )

seanet

why this link Can not transport More than 35 mbps real traffic ?

CCQ always more than 95%
RX / TX signal level ( 55-60 ) / dual chain
output power 17
Free LOS
distance = 1200 m
