You'd also need copper gigabit, so if there are nanoBTS and UmTRX at
the same location we can't just have a single gbit upstream going to a
local 100 switchs for example (like the PoE switch we use for
nanobts).

Yes, VLAN will share bandwidth on the upstream links / core network.
But if the core network is 10Gbe ...
