Hi guys,
It's been a long time I am away from the forum. I have moved to Mavic Pro now, but still running a group of 600 members in my country who owns Spark.
I was also the one actively built up lots of theory about the battery matter during the very first days of Spark release, and seems like my theories are correct about both hardware and software matter of the battery.
Anyway, that's another story. my purpose today is talking about Spark range and FCC/CE.
If looking at the Specs of Spark, we will see that Spark use Wifi, and can run on both 2 frequency 2.4 and 5.8GHz
in each frequency, DJI divided into 2 standards FCC and CE. Details as following:
-2.4GHz: if FCC = 2km, if CE = 500m
-5.8GHz: if FCC = 2km, if CE = 300m
First talking about the frequency: 2.4 is the common one we can see people use with phone, routers,...That is why it is vey susceptible to interference. However, the range is a little bit further than 5.8GHz (and the channel name is in 1 or 2 digits: 1, 2, 3, ..., 11, 12, 13). In 5.8GHz, it is newer, therefore less people using this frequency, therefore less interference, but the range is a bit shorter 2.4GHz, and the penetrate ability is also weaker than 2.4GHz (The name is in 3 digits: 149,...)
Talking about FCC/ CE: FCC is the America standards, allow longer range (as you can see in the specs 2km), and CE is for Europe (much much shorter, or I can say make Spark become useless). So, if you are living in a country that is not America or Europe, we have our own standards (Like me in Vietnam). But DJI will not go through all the trouble and make a bunch of different standards for all the countries in the world --> So, logically what they do is apply the shorter standard on you (to protect themselves against your countries' laws, of course). Now, if you ask DJI staff with standard they apply to your country, I did try, they told me they apply FCC for VN...That's is BS, don't believe them. Fortunately, there is a way to check. If you are in FCC, the number of 2.4GHz channel you have are 11 channels, and if you are in CE the number of 2.4GHz channels are 13 channels.
So, if you think your live image is suck, the range is suck (like me, when in CE, I can only reach the radius of 50m with remote controller), then your only way is trying to get to FCC.
How to get to FCC? There are a few ways that you can google by yourself.
You will ask me if I am afraid DJI will read this post. No, because: Firstly, I am only stating the truth, I did not show you how to break the laws. And if you decide to change to FCC, you are the one to be responsible for your countries' laws, not me, not DJI. Secondly, FCC is what increase the sales number of Spark for DJI, therefore, actually I am helping DJI for not getting their hands dirty...
I hope this thread is informative and hope I can help you enjoy your Spark more.
