Wow plenty of rambling but that's cool.
No, the cell was seemingly more congested. I have direct line of sight to the tower at just under half a km - well, apart from my roof.
I'd say my signal is quite adequate
RSSP: 73/ 75
RSSI : -51.. never fluctuates
RSRQ: -4 / -6
Just hit a peak off 119mb down and 44mb up on the mobile connection alone which isn't too shabby.
The reason I guess it's congestion is the cell controls when its on 4G+ as most of the time it sits at 4G despite me telling ti to aggregate the channels. Only when it requests data at above 60mb will it flick into life. I've manually throttled connections to test this. Once it goes over it changes modes and then ramps up again.
When it was flickering 4g+ and off it was still hitting around 95mb which tells me signal is fine considering the theoretical max.
I decided I'd keep the 715 as it was only £170 and at leas this is more future proof.
It's also nice to see a load balanced connection of 150mb down and 50 up considering the best that my neighbors have ranges from 30-35.
My connection history:
