Of course I will give you some Information to use -
I read that in FCC mode there isnt so much difference between 2.4GHz and 5.8GHz.
In CE mode there is a lot although the db Power Gap seems small its actually about x4 as much more in FCC.
DJI Spark range settings (taken from the DJI website):
2.412 – 2.462 GHz (unobstructed, free of interference)
FCC: 1.2 mi (2 km); CE: 0.3 mi (500 m)
5.745 – 5.825 GHz (unobstructed, free of interference)
FCC: 1.2 mi (2 km); CE: 0.18 mi (300 m)
If you have 1-13 Channels you are EC, if you have 1-11 Channels you are FCC mode. These are the 2.4GHz.
2.4GHz best for long distance as Wave is LONG WAVE (Long Distance Eg. Repeaters)
5.8GHz best for short distance as Wave is SHORT WAVE (Under 200m Range Eg. Indoor Wifi)
The other problem we have in EU is that 2.4GHz has a lot of traffic and the 5.8GHz is not supported a lot like in the US.
Also this may help you -
The transmitter power is the same for both. Antennas and encoding make the difference.
The specs say: Spark:
Transmitter Power (EIRP)
2.4 GHz
FCC: ≤26 dBm; CE: ≤18 dBm; SRCC: ≤18 dBm; MIC: ≤18 dBm
5.8 GHz
FCC: ≤28 dBm; CE: ≤14 dBm; SRCC: ≤26 dBm; MIC: -
The dBm in CE is ridiculous !
The dBm between FCC and CE at 2.4GHz is 8dBm that makes a difference from EC - 500m to FCC - 2000m range.
The dBm between FCC and CE at 5.8GHz is 14dBm that makes a difference from EC - 300m to FCC - 2000m range.
