Hi, Behcet,

The use of frequency bands at Starlink is worth considering, because
there are more and more small satcom devices that can text and voice.
These devices are potential help for users in search for connectivity.

We are used to think that 2G evolved towards more and more uibiquity.
But the situation of connectivity availability is still far from ideal.
  Satcom can help with remote areas such as mountains and sea, in some
countries, but there is more than even that.

Today, if one wants to own a single smartphone to use in all countries
in the world then that smartphone must be large, expensive and
energy-hungry.  More normal versions (cheaper, smaller, less consuming)
of these smartphones are limited in the number of countries where they
could be used.  E.g. my 2G voice phone works only in Europe and some US
but not in Korea; my 3G phone works ok in Korea, Japan and some US but
not in Europe, and similar.

If one wants to be reachable in montaineous our sea areas then one has
to carry one or several satcom devices as well.

In detail, one can realize this difficulty by considering the number of
frequency bands (50?) implemented by a 5G-and-LTE iphone of recent
generation, the different versions of iphones and the list of countries
where they could be used.  See for example the huge table listing
frequency bands, countries and iphone models at this URL
https://www.apple.com/fr/iphone/cellular/

Ideally, in 6G, there will not be an additional set of another 50
frequency bands.  There would be maybe one or two more bands, but
larger. They would be agreed on a larger scale by more countries.  But
that agreement might be difficult to achieve because I am not sure I
know single freq band that is agreed by all countries in the world at
this time.

This is where I would like to ponder over this question: what can be
done in 6G such that the end result is that one owns a single smartphone
able to connect in all countries in the world, on mountain and at sea,
that is small, inexpensive and not very energy consuming?
