Wireless link calculator updated

Here is a first look of the new updated wireless calculator:
https://mikrotik.com/calculator

Report any bugs you can find and we will try to improve it.

Of course, this is a synthetic calculator (theoretic). Real life has things like interference, weather and other factors that will reduce possible distances.
A known bug, that in Chrome, the elevation graph doesn't support hover over specific hill. Currently does work in Firefox/Safari.

The calculator does take into consideration the elevation, the fresnel zone, the earth curvature. It currently does not tell you exactly how big your towers need to be, but it will tell you that you need a big tower, if there is difficult elevation, or earth curvature that disturbs the 60% fresnel zone.

How to use:

1. Choose the frequency band
2. Choose the minimum required data rate
3. Choose the products from the list
4. Move the map markers to the desired area.
5. Click "calculate link"
6. Observe the elevation graph. Move your mouse to the hills, so see which ones might cause issues. Drag over the elevation graph to select bigger areas, to identify them.
7. Adjust products or markers until the result is "Reliable" and doesn't mention that "Very high tower needed"

Please comment here if you find problems, mistakes or other issues.

Very nice service :-)

It will greatly increase usability for me, if i can add arguments to the URL, especially location/coordinates and the zoom level.

How Google has done it: https://www.google.dk/maps/@56.1491919,9.9064497,8z

Easier to read suggestion: https://mikrotik.com/calculator?longitu ... 497&zoom=8

Lovely, thank you very much Normis.

If you will let the calculator load the value for all the available input/drop-down etc. boxes from the URL, then i can also add direct links on all the individual product pages on my distributor site :-)

Look good, congrat

But if you can't put the exact gps coordinates for the Tx Rx points, and tower weight (isn't same if I have 2m or 5m tower) is only to play.
Another small think, doesn't fit the configuration panel and the "Reset" "Calculate link" button in the same screen, need to scroll.
Is my 1600x900 monitor resolution to small, I don' think all peaple use fullhd resolution. Maybe you can decrease a little that config panel window.

Sorry for remaks. It's an awaited tool, thanks for it.

OK, we will add those features. None of our monitors need to scroll that panel. Do you use some scaling in your OS?

Hello Normis,

This is great!!

I especialy like the height indicator as you "scroll" along the height graphic.

It would be nice if we could click to position the markers rather than drag them. I also agree for a tower height field.

Great job guys! :)

1) Manual height override for both points (or mast height)

2) on the sea don't allow to go into negative height :)

3) allow to place link on left-mouse click, so you don't have to search where did you left your link previously :)

Hi Normis

Congratulation to Mikrotik ! Very nice and useful tool.

On data rate selection for some device like Disc, it allows to select up to the highest, which i doubt on the possibility.

Maybe I'm using this wrong, but it appears to me that if I select a product the calculator fills in the maximum power of that product, and then doesn't let me edit that figure if the maximum power is more than I can use legally in my area.

Select the data rate first (top to bottom). It will then read the values from the selected data rate.

Thanks!

Nice tool. Will be good if one can simply enter coordinates of the TX and RX location as an option to just Moving the map markers to the desired area.
Also, the ability to export the report out in jpg/pdf or any other usable format will be fantastic.

However, this is a very good tool as it is.

Now what would be really cool would be to have would be a question/answer session and presto a parts list of everything needed.
Questions such as:
- Desired network throughput at the Ethernet ports (full duplex or half duplex UDP/TCP)
- PTP or Multi-Point to point
- Distance & elevation & GPS location (line-of-site-analysis)
- Full network redundancy desired (dual links) & desired network up-time percentage
- Fade margin (allow for not-so-perfect aiming and not-so-perfect weather)
- Ability to pre-load some non-Mikrotik antennas (and save non-Mikrotik antennas to database for future calculations)

Then auto-generate a Mikrotik parts/build list and network through-put summary and a map. (Possibly include some common/standard high-gain non-Mikrotik antennas. This may increase distance). Possibly print several build options.

These kinds of build/parts-list auto-generate calculators are already available in the fiber & cable world by several large vendors.

I think it would benefit any non-tech person to select Mikrotik products when building/designing a microwave network.

This only finds your current position (point). There are two markers though. We have to place them in random positions then? Isn't it easier just to place markers where you want them with right-click?

Hi Normis,

Agree the second point would be random in that case. I worked out how to put a link on my website with two points local to our geography which was great. (see earlier post)

If you could perhaps have a button to set the map to your current location then you place the points would be good ? Or perhaps type in a start point name or co-ordinates ? Zooming out and scrolling to your country and then back in to find your location works, but is slower.

Tower height would be very useful - someone else suggested this I think.

These are all 1st World problems of course - the new calculator is great - just trying to make it a bit easier for our users :-)

Great job, just some doubts:
1) is there available old version somewhere? (better to manually set cable and antenna parameters and other calculations...)
2) on device selection there are available 4 models of Netmetal5: are them all equal?
3) Tx/Rx gain (I suppose is gain of antenna)... so "Output power" is power of card or irradiated power? I suppose it would be power card; in my country maximum EIRP is 30dBm, so I should use 0dB power for wireless card, why can't I set output power to 0?

thanks,

Maybe a explanation when "Link status: Link impossible"

Because I can't figure out how in an open field, 2 LHG HP5's would not be able to setup a connection over a distance of: 0.7 Km (0.43 miles)
https://mikrotik.com/calculator/#map:52 ... 1011199952

What am I doing wrong?

A copy link button in the "Specifications and results" windows, the button on the map gave me a link, but only after the 4th try(?)

Nice tool - but I don't understand why the power goes up as the required speed goes down. Take 2 SXT sa 3km apart, and at 6Mbps power is 31dbm and for 150Mbp it's 27dbm. Is this the power setting needed at the radio? Not very helpful when we most of us are limited by country EIRP rules. Could we have a max EIRP box to see if the link is possible and legal?

This is how wireless works. You can see the TX power tables in the product pages:

https://mikrotik.com/product/RBSXTsq5nD

As you can see, the chip is unable to transmit at same power when a high speed has to be sustained.

Actually no, it will be less precise, because the calculator uses the data from the map, to calculate the link. If your coordinates may be more accurate to the real life location, but in this case, it is more important to match the point with the map, not with the real life. This is because terrain data will be taken from the map.

Sattelite layers that we use are very good, they are from ESRI and have nothing to do with openstreetmap

Hi,
cannot get working elevation graph.
Specs and results - all values entered properly.
"Link status" = Reliable, but elevation graph always shows 1m x 1km.
Used FireFox, Chrome, other browsers - no matter.
Could you please advice - how to get elevation?
