Long range video streaming

[juanjo_asensio]

Hi there,

We want to stream video at a reasonable quality (HD) using the STM32WL, we were thinking on implementing this feature using LoRa, but looks like Sub-GHZ system isn't no capable for transmitting video.

What other methods can we use that can transmit video for around 6km (it's for a drone)?

Thanks in advance and sorry for our unexpertise.

LoRa brings Kbits in a problem that needs Mbits

There are several companies specializing in wireless video at HD, perhaps look at the technologies they are using.

Thanks, but's way complex to find such Integrated Circuits.

Could you please let me know which are the most common used ones in the actual industry and that are well integrated with STM32?

Yes, tends to be niche and proprietary, frequently with NDA and IP Licencing. Long distance, high power, often into the realm of licensed bands. Have to looked at 5G Cellular?

Perhaps start looking at what the UAV crowd are using.

HD video, not really the realm of Cortex-M MCU's

Thanks, I'm having a look at it. But some companies have pattented their own improvements to transceivers so achieving that distance might be some quite difficult.

I know that this might sound horrible but: What about adding some buffer and frequency amplifiers for this purpose?

We can transmit a wave and then kind of remodulate it and amplify it for having a higher speed.

Is this usual or at least good enough?

Thanks for your answer, as I said previously I discard LoRa but buying 5GHz transceivers isn't an easy task.

I left this open in case someone knows which one is the most recommendable and affordable.
