Can we use 256QAM modulation in mmWave? Does this frequency capable of carrying data at high modulation?

Question

I have seen 256QAM for mm wave but no body spoke about sub 6Ghz, is this applicable?

Answer 1

It will be an optional feature for Rel-15 but will depend on vendors... huawei will support 256QAM in FR2 band range, but willl be licensed seperately since it will not be in basic feature package.
