I was bored and thought I would do some poking around in the RC.
Found the default for wifi distance calcs on mine are disabled.
Coverage class: 0 (up to 0m)
I made a comment in another thread on why Magic Power works in FCC areas due to the ack packet timeouts and remembered there was a patch a few years back that enabled auto calculations.
I could not get the RC to accept the auto setting to enable this but I did find The coverage class can be adjusted.
I have found the following:
2 up to 900m
3 up to 1350m
4 up to 1800m
5 up to 2250m
6 up to 2700m
7 up to 3150m
8 up to 3600m
The RC will accept any of the above settings. I have not tried them but believe at longer distances the settings will make a difference.
Hopefully I can start a discussion. I know there is a math equation that calculates distance from the RSSI signal based on frequency. I was hoping to use this calc to get an estimated distance. Then change the coverage class to the above setting corresponding to the calculated distance.
Magic power uses up to class 5 to improve video based on signal strength. I have seen others taking the P3S to further than 2250m so a way to use 6 & 7 might get them further. PapaTita may have already looked in this area an I am not going to re-invent the wheel. If the idea works he may add it into his program.
I am ok with scripting but I am not a expert with maths! This is where help is needed.
This is the equation I have found to work out distance in metres using freq in Mhz
distance metres = 10 ^ ((27.55 - (20 * log10(frequency)) + signalLevel)/20)
have tried a few examples but can not get it to work for me.
Any ideas.
