just a few notes from my end about wireless streaming and hiking. I did some development work to get the maximum quality out of my Z1 and as a result here are a few samples, using my own plugin: https://www.flow.tours/en/product/33 , https://www.flow.tours/en/event/vigado . Sorry, not sure what hiking means for you…
What I want to highlight is that for a proper quality you need about 18-20mbs upload speed on your mobile device and above live streams I did in city center, where network speed was good enough. Usually at hiking places, the bandwidth is worse, at least in my place. If there are particular locations test the upload speed there…as without a constant 18-20mbs upload bandwidth, you may never get the quality you expect during live stream. You can use on mobile too to measure: https://www.speedtest.net/ but pick an international destination for testing as local bandwidth may not be the same.
