4G+ on your display means you are receiving at least two signals and combining. For more have a read of this page I wrote over the Christmas period.

it's a constantly evolving space... spectrum refarming, upgrades to more MIMO, more carrier aggregation. 5G coming up...
It's also sometimes a little difficult to figure out what a router supports - and even harder (without signal testing) to really see what a network might offer in a particular location. (I'm thinking MIMO and CA, let alone sometimes what bands are used)
