Bandwidth and latency testing

Hi everyone,

Im interested to see what everyone’s Uplink and downlink rates are with reference to length of tether and if you are using a slipring or not.
My system is working great, but i have an uplink of 37 Mbps and a downlink of 48 Mbps. I have 275 m tether through a slip ring. not sure if this is good, bad or goldilocks.

Thanks

Paul

I would say this is really good.

I usually get around 25mbps at 300m.

For me, with 200m slim tether, 30 à 40 mbps maxi…

With 150m of tether and slip ring, with my laptop mid to upper 70’s up and download. With my toughbook a little less mid 60’s.

Thanks everyone.
It’s good to have some numbers to compare.
Looks like my bandwidth is certainly similar to others.

Just checking here about Bandwidth and latency testing.

Does anybody know why the download stream behaves like that? (speed goes up to 50mb/s and suddenly falls down to around 15Mb/s and then climb back up again).

Download: 50 Mbps
Upload: 76 Mbps

Details about the unit:

BR2 - Regular
100M Slim tether
Fathom-X
Blueos: v1.1.0
ArduSub: 4.1.1
QGC: v4.3.0

Hi @Thor -
The speed test is something that needs improvement, and is being worked on. From what I understand, in some ways you’re measuring the Raspberry Pi disk write/read performance in the test, hence the behavior of a peak at the start, as buffers are filled? The results you’re seeing look nominal for a slim tether @ that length!

I was not sure about this. Thank you, Tony, for clarifying this for me.
