Long range communication module with high data rate (e.g. for video streaming)?

Other Hardware General Electronics
1

I need a module compatible with the arduino where I can send big data over long range.

I am searching for a module with a range of approximately 2 km range, a daterate of 1,500 - 4,000 KB / second (for video streaming) and RSSI support.

Here are some that I have looked at, but do not meet my requirements:

SI4432
RSSI: yes
range: 1.5km
rate: 256KB / s not enough :frowning:

rfm95 oder rfm98
range 2.5km
RSSI: yes
rate: 300KB / s not enough :frowning:

SX1276
range 5 km
RSSI: yes
rate: 300KB / s not enough :frowning:

HC-12
range: 1.8km
RSSI: no no RSSI :frowning:
rate: 5000 KB / s

Thanks for your recommendations!

Hi,
What model Arduino do you expect to handle video streaming.
What quality video.
You need to research radio digital links, frequency, bandwidth, and local regulations with regard to power levels.

What is the application?

Thanks.. Tom... :slight_smile:

Thanks for your answer.

What model Arduino do you expect to handle video streaming.

Arduino Mega R3

What quality video.

In my dreams: 1280 x 720 pixels
In reality: 480 x 852 pixels (in case of need, less)

You need to research radio digital links, frequency, bandwidth, and local regulations with regard to power levels.

frequency: I don't know what is the best frequency, but anything between 433Mhz and 5.8Ghz (license-free ISM band)

bandwidth: 1,500 kbps - 4,000 kbps

and local regulations with regard to power levels: I am in Austria. (in the European Union -> license-free ISM band)

PS: I use it for a self-built quadcopter.

"In your dreams" is where the Arduino Mega R3, with its whopping ~8000 bytes of memory and 16 MHz clock, will remain.

As for the radios, the figures you quote are completely unbelievable. For example the SX1276 might work at 5kB/sec, at 5 km range, but certainly not 300 kB/s.

unbelievable

If it's impossible, how does it work in Dji mavic pro 2, which can stream a video stream of 1920 x 1080 pixels up to 8 km.

How does what work? If you want to know what is inside the Dji Mavic Pro 2, ask the manufacturer.

What YOU are proposing will not work.

I quite agree.

I did once get 13.7kbits @7dBm @105km, with LoRa on the SX1278.

But LoRa has a maximum data rate of 37.5kbits so the quoted 300kBs would be using the device in FSK mode and 5km does seem a tad optermistic.

These are all UHF based systems.

I am not aware of any UHF systems that will legally allow such a high datarate (4Mbs) which would require a high bandwidth ...........................

If it's impossible, how does it work in Dji mavic pro 2, which can stream a video stream of 1920 x 1080 pixels up to 8 km.

Maybe they are not using UHF modules ?

Maybe they are not using UHF modules ?

They are using 2.4Ghz and 5.8Ghz.

Alwin07:
They are using 2.4Ghz and 5.8Ghz.

Yes, they must be, so what was the point of quoting the specifications for UHF modules ?

11

"Video streaming" over distance is called "television broadcast".

It requires a television transmitter with an appropriate licence.

They can do it because of the research, technology and specialist hardware available to them, hence the plus $1500 price tag.
It is much more than just choosing a wireless link freq/bandwidth.
Can you please tell us your electronics, programming, Arduino, hardware experience?

Remember that in a lot of places in the World, UK included, a video system that will go 8km is a bit pointless, since you cannot fly beyond un-aided visual sight, for a drone that size maybe 1km max.

Dji will know this, so you do wonder why they advertise a feature that most people cannot use, legally.
