Webfeasibility of using lower cardinality 64-QAM and 256-QAM formats, while increasing the symbol-rate compared to our previous work[7]. This allowed us to improve our previous secret key rate results to 67.6 Mb/s for PCS 64-QAM, and 66.8 Mb/s for PCS 256-QAM, over 9.5 km of SMF. Both rates are averaged over 200 blocks of Web256 QAM - DL . From Rel 12, 3GPP defines (support) 256 QAM in Downlink.
