Hello ,
I have referred the manual of mikrotik. But couldn’t understand much about wireless station modes.
Can anybody help me to learn Wireless station mode in simple terms and when to use it and advantages and disadvantages for the same.
Thank you.
Use this mode when you don’t need to bridge wlan with other interfaces. So it is in case of routing only or using wlan for the device’s own connection only.
Hello ,
Thank you for your reply.
I have been trying to setting up a link of PTP 20KM link with tx/rx signal -71/-72dBm but couldn’t get throughput.
i tried that it NV2 protocol with 5 GHz only N in Station Bridge mode.
How to use other modes?
If both involved radios are mikrotik devices, use ap bridge mode on one side and station bridge mode on the second.
See: http://wiki.mikrotik.com/wiki/Manual:Wireless_Station_Modes
-71 sounds close to the borderline of being within 20dbm of noise floor… What is the listed RX sensitivity of your model of routerboard for the modulation rate that you’re attempting?
For instance, MCS9 on SXT 5 ac has RX sensitivity of -72…
Hello,
I have both side installed BaseBox 5. with antenna gain of -30dbi.
RX sensitivity for that unit at MCS7 is -75 so you’re just getting strong enough signal… Are you seeing bad modulation rates, or just “less-than-expected” data throughput?
I’m not sure about NV2 but 802.11 usually only gets roughly 1/2 of the modulated rate as data throughput. So a 150Mbit mod rate lets you expect about 80Mbit of payload throughput (in my experience) and also remember that wireless is half duplex, so that’s 80M in total (add both directions’ throughputs together and that must be at or below roughly 80M).
Actually bad modulation rate , CCQ of Tx/Rx is not enough to even access the internet.
Tried 5Ghz-A also with NV2 , even tried 802.11. But no good
Have you checked fresnel zone clearance?
You may be getting multi path interference from reflections, etc. What about interference? You should be a full 40mhz away from any other channels in use at that tower. (Side lobe interference)
You may also need back shielding on the dish and radio.
Hello ,
I am a beginner for mikrotik.
please help me for this.
why tx/rx for both the channel have lot of difference?
How to configure it?
I’ve always felt like my grasp on how to interpret the tx/rx strength in Mikrotik is wrong - there are some contexts where the values of TX/RX are displayed from the perspective of the thing being monitored (e.g. user tx/rx in hotspots are reported from the perspective of the user, not the Mikrotik, whereas tx/rx stats on physical interfaces means relative to the router itself)
So when looking at the tx/rx rates of a particular connected station, is this the STATION’s tx-to-AP / rx-from-AP, or is it the AP’s tx-to-station/rx-from-station?
However, one thing that stands out to me is that you have a large disparity between the two chains - which leads me to believe that there’s a polarization issue in your installation.
Furthermore, out of the 4 tx/rx values shown (chain0 and chain1), only one of them is above the rx sensitivity required for MCS7 modulation rate. You should double-check the antenna alignment and the cabling between the radio and the dish.
~25% CCQ is abysmally bad - which means that you’re getting lots and lots of failed transmissions. Part of this is probably due to the fact that your signal strengths are below the threshold for good modulation, and the radio is probably going through repeated cycles of attempting to use faster modulation rates, getting too much errors on those rates, slowing down, improving, and attempting to speed up again.
Hello ,
let me check with alignments. Actually I have been using UBNT before this so i am practicing this connecting 1 device.
AP is MaNT19dbi Sector with basebox 5 and Client end is SXT Lite5.
