Been using three for BB for since September as my fixed line VDSL is naff (roughly 25mb)
Using the AI cube and 3 deco M5 mesh wireless network.
Speed in generally good, between 50-70mb most of the time. But when testing with a mobile standing in the same spot right next to the AI cube I can get 120mb+ on speedtests.
This was tested with my old OnePlus 3T and my new MI mix 3 5G. Mast is only 2x2 Mimi which I checked with network signal guru.
CA is locked on the AI cube to bands 800&1800.
Obviously tried the ai cube own WiFi just to rule out the decos slowing things down but still can not get close to what mobiles can do.
Any other ideas or is it just a case mobile chip/modems are better?
