Hi, Dirk,

I agree.

Recently I learn tht the most advanced specification towards 6G at 3GPP 
is '5G Advanced'.

Maybe after the '5G Advanced' specifications might come '6G' specifications.

In that list of pdfs, there is one that could be improved, because 
things have evolved since Nov. 2020.

With respect to KPI 'bandwidth' - at that time I was putting a question 
mark next to 5G bandwidth, wondering what would that be.

The white paper "Whitepaper Beyond 5G/6G KPIs and Target Values" of June 
2022 calls 'bandwidth' a 'datarate'.

The KPI 'datarate' for 5G ranges between a value experienced by user, in 
theory, at 100mbit/s up to a peak theoretical value of 20gbit/s.  A 5G 
smartphone user might see xx mbit/s at speedtest.net (I still have to 
identify that xx value).

For 6G, this KPI 'datarate', during this decade, might be from 1gbit/s 
up to 10gbit/s.

This increase might be achieved by increasing the width of the band (up 
from current 360mhz), at higher frequencies such as beyond 75GHz.

But this datarate increase is not the only important KPI for 6G 
connections.  There are many other important KPIs such as the distance 
from base stations, the energy consumption, the possible density, and more.

These things do have consequences of how IP is used on these links, and 
that is what is even more important.  A potential 'Terahertz 6G' has 
many impacts in how IP works.
