Today, 90% of the phones in the world are still analog. Including
mine,
in the capital of California and my buddies' in the heart of Silicon
Valley.
the (static) statement that "90% of phones are analog" seems very
wrong to me.
according to newest ITU-D estimates, by the end of 2004, there were
1.2 billion land lines, with an average annual growth rate of 5.8%
since 1999. this means 18.99 lines per 100 world inhabitants [1].
i ignore how many of these lines are analog, but what is for sure is
that the most phones today do not have any lines at all: at the same
time, the ITU registered 1.76 billion cellular subscribers, with an
annual growth rate of 29% since 1999. This makes up for 27.61 phones
per 100 world inhabitants [2].
the vast majority of cellular phones are not analog (GSM+ being the
nr 1 technology [3]) and thus probably less than 50% of world phones
are analog.
i don't know how this relates to the current nat/ipv6/ipv4
discussion, but the argument above could be easily turned into a
counter-argument: one could have said that with the original analog
phones we were not able to solve the digital divide in the voice
service and a new technology has become necessary :-)
