Thanks a lot for looking into the details.
I understand that if latency of the bonded connection is significantly different than it is not possible to reach higher speed than the faster connection in the bonding.
However celular connections cannot guarantee a healthy performance / latency permanently.
As consequence I see two use cases which I would like to solve:
Use Case 1 - Degradation of one connection: Avoid that the speed of speedfusion tunel gets lower than the faster connection
Use Case 2 - Both connections are healthy: Reach higher speed than the faster connection
I suggest dealing with these two use cases separetly.
Could we please focus on Use Case 1 first?
How could I avoid that the degradated connection couses degradation of the entire speedfusion tunel?
Your feedback has already gave me some ideas about suspending more agressively the degradated connection based on Latency Difference Cutoff. My new settings:
I will do a fresh re-measurement overnight to exclude load of other users on the tower.
Once Use Case 1 is fixed, I would start to experiment with the radio performance for Use Case 2. Indeed cellular 1 (LTE12) has a much better external antenna than cellular 2 (LTE4).
cellular 1 (LTE12):
cellular 2 (LTE4):
As the SIM cards are from different providers and I do not use any splitters and amplifiers, I do not see how could they interfere on the frequencies … … but happy to look into that if there is any scientific explanation how an interference would be possible - so that I know what anomaly I should look for.
