Mikrotik SXT LTE6 LAN Speed Connect up to 300 Mbps in downlink The LAN interface card is only 100Mbs!

Hi everyone, I’m Enrico from Rome, I bought a new Mikrotik SXT LTE6 antenna.
I have a question, reading the technical specifications I see that it is LTE CAT6 and can connect up to 300 Mbps in downlink
The LAN interface card is only 100Mbs!
How is it possible ?
With a 100Mbs card in theory it loses part of the downlink !! The download capacity of the antenna is cut !!

Thanks to all,
E.

You can perceive things like that.

But more likely, with many LTE users around, you’ll hardly see actual throughput hit 100Mbps … 300Mbps is theoretical peak which can be achieved if signal level is perfect and you’re the lone user of both cells used in CA. In reality there will be many users in the same set of cells (and total cell capacity gets divided between all concurrent users) and if signal is not perfect (i.e. always) throughput drops as well.

Few ppl here do a bonding of ether1 and ether2 and can reach ~190Mb/s DL but this step demands second device.
PS. Good practice will be disable PoE-out at ether2.
