I would like to stream video from a Raspberry Pi over RF to another Raspberry Pi. Here are a few requirements:
- Range of at least 1KM (pretty much line of sight)
- I would also like to send some data along with the stream - or simply another packet (would just be a couple of sensor readings)
- It needs to work across the land, ie not a HAB - I saw somewhere that there was a zone when transmitting across the land?
- The video stream needs to be of high enough quality to be able to see it, 720p would be ideal but I understand that that is a lot of data
- Ideally the two Pi programs can be written in Python
- power is an issue, although not a major one so low powered is good!
- the streaming Pi would be moving (within the 1km range) and the other Pi would be stationary
I am in the UK and know that for 2.4GHz and 5.8GHz you don't need a licence, is that correct?
Is what I am asking possible and feasible? I don't want to spend too much money and am looking for a DIY solution.
I've been testing some NRF24l01 + PA+LNA modules, one with an external antennae and one without, but am getting really bad ranges (5m - line of sight), I am running them at a datarate of 250KBPS and at the maximum PA. I was wondering if anyone could shed any light on this too? Ideally, I would like to use them for the above project.
