Millimeter wave link with a data transmission rate of 40Gbps

Hello Expets,

I’ve read that in Deutsche Telekom, Ericsson has achieved 40 Gbps in E-band backhaul trial

But from what I know E// has MINI-LINK 6352 which supports 10 Gbps over 2000 MHz channel.

So: how could they achieved 40Gbps over a hop distance of 1.4 km?

Due to distance and climatic zone, I think they are talking about D Band link 64/128QAM - >10GHz bandwidth
