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

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

Re: Wireless link calculator updated
hi normis...
yes the tool by Mikrotik is good but i found the maps a bit unconvincing. also could not enter the Lat and Lon directly.
any chance of using Google Maps?

Re: Wireless link calculator updated
Satellite is always better than street map, since you can see the building or the terrain. Did you enable the satellite view?hi normis...

Re: Wireless link calculator updated
Yes... I enabled Satellite View.
but putting in direct Lat / Lon does help in being more precise.
as i said the Openstreet maps do not have much of details for my area as Google Maps.
Google Maps is showing everything in great detail.

Re: Wireless link calculator updated
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.Yes... I enabled Satellite View.

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

Re: Wireless link calculator updated
VERY COOL update
very useful as it fully integrated on earth's Terrain.
pole height could be verified and Router models and antenna gain is a good feature.
cant wait for the dude update

It will be nice and useful , if you add two filed for height of towers and draw fresnel zone . some thing like this :

It would be very good to be able to put structure, antenna heights at each end.

Re: Wireless link calculator updated
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?

Re: Wireless link calculator updated
Same problem here. Works fine except North America. Got it working yesterday for awhile, but tried it this morning and no go. The elevation display fails to update, both height and distance. Stuck at 1km right now. If I go back to Europe, stock there too. Did a reset in Europe, started working OK, then moved back to North America, no go. Elevation map carried across from Europe. Reset did not work.
Useful tool if it works

Re: Wireless link calculator updated
The problem is that it is calculating the longitude incorrectly. Like 238 for san francisco, instead of -122

Re: Wireless link calculator updated
also experiencing same problem re elevation for here in RSA
Re: Wireless link calculator updated
I solved the problem with longitude in USA by proceeding west from Europe to the USA. It then calculates longitude correctly.
Love the calculator. Gave me some idea of how some of the wireless products worked with each other.
I presume it doesn't take into account trees or buildings. Plus one on adding tower height as an option.
Thanks

Re: Wireless link calculator updated
Are you guys offering API to access this https://mikrotik.com/calculator for integrations?
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.
