Most operators are deploying 5g in the last years already with 4g handware that can be software updated to 5g. And the 'legacy' systems run in a lot of cases as software defined radio on 4G hardware. The only thing you see is exchanging antenna systems, because that's one of the things where physical relation (spectrum = wavelength) is showing up. |
