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
I think they use aggregation and a high QAM (around 16k afaik) to do that.
If you are really interested in data transmission rate limits you should take a look at this paper (just as old as this topic but pretty underrated):
