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.
Sure, if you know how to use it, it is very good. This tool is more for quickly selecting a suitable product. Simple.i will still stick to Radio Mobile.... it's highly accurate!
you have posted this in the wrong thread... please post this in the Wireless section.when i login hotspot mikrotik and off my laptop and the return back isee another accont login in my laptop that is login and i can use the internet
Like that another person uses my laptop why?
Satellite is always better than street map, since you can see the building or the terrain. Did you enable the satellite view?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?
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.
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.

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

Here is a first look of the new updated wireless 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"
