5G on Nokia Micro BTS

Nokia introduced a range of LTE capable Micro BTS in 2016 - the “Flexi Zone” units.

Does anyone here know if:

  1. The original range of LTE “Flexi Zone” units are upgradable to 4G/5G NSA ?
  2. There is a new range of 4G/5G capable Micro BTS available ?

Thanks

I remember I read some stuff that Nokia is working on the 5G NR-U(unlicensed spectrum) as the next generation.

Cool. I think it would make a lot of sense to deploy 4G/5G NSA Micro BTS instead of 4G-only Micro BTS.
