How Lightbridge has +5km range?

Hello Everyone,

I made some research on the internet about long range communication with ground station and drone. What I can find is, If you want to build your own long range system, so you should use dish antenna with antenna tracker. Btw, with long range, I mean +5km and more.

But problem is, If you have 3 drone that you are controlling and all of them has let say HD video streamer, you should use 3 antenna for collect all video data from drones. (because I should use omni directional)

As everybody knows, lightbridge has a very simple system and all antennas they have are omni directional. Also as I can see in specs, the transmitter output is 100mW which is not that much high for +5km range.

First I thought about frequency, but lightbringe has 900MHz, 2.4MHz and 5.8 MHz configurations that all of them can communicate +5km.

I'm really wondering how lightbridge can communicate in +5km?

Thank you everyone

  • well, 5km is done easily, just as if they said 10km:  it's a marketing thing, they lie about it.   I would not say it's reliably usable at even 2.5km - in areas with not too many other RF sources in the same frequency range.

    Then you have the slow error correction/buffering/whatever, the framefreezing and quality drop that comes on top of the huge latency.

    Of course, that's to be expected with compressed, digital transmission - but there are better HD alternatives with insignificant latency.
