My city :) I'm happy that this is finally happening, however it's still a very "test"-type of project, so only one location, small coverage area, and [almost] no devices that can utilize the network. Telenor is a leader in 4G and 4G+ coverage in Serbia, and I'm quite happy that they're the ones to commit to 5G so early on.

Disclosure: I'm not employed or compensated by Telenor or any other associated subsidiaries or parent companies. I'm just someone who loves fast mobile broadband and new technologies :)
