[LINK] Mobile Internet

[Chirgwin, Richard]

Bernard, sketching only:
1) mobility and IP addressing is part of what the whitecoats have in mind
with IPv6. There's a concept of "home" location and "proxy" location that
lets a user go from cell to cell (for eg) without having sessions lost
because of a new IP address allocation. However, not many telcos have taken
v6 address blocks yet ...

2) re CE: my vague understanding is that Microsoft Mobile Information Server
will map dynamic addresses on the network side to static addresses on the
device side. No guarantee of accuracy about this, though.

First, the term Mobile Internet is a misnomer. Gartner seem to be the main
user of this term but when challenged, they admit it doesn't make sense.
Nobody is going to be able to surf the Internet on handheld devices real
soon now. The display is inadequate and the bandwidth just isn't there.

Second, there are many applications where a limited device over limited
bandwidth (especially in the Business to Employee space) can provide
significant benefits.

Third, with GPRS, there will be IP to wireless devices.

Fourth, on WinCE there is no DHCP, so for those devices IP addressing will
need to be static.

Question 1: does anyone know what the telcos will be doing about allocation
of IP addresses to so many new devices?

Question 2: does anyone know how Microsoft are able to get round this WinCE
problem? Microsoft claim "that is not a problem if you use the MS Mobile
Information Server" but I can't find out how they are doing it.
