Question about USB WiFi and Bluetooth (again but somewhat new; )

[Robert Michel]

Salve Koen, Alessandro, *!

I' just a student interested in OpenMoko, so I have my information
like you from the news, the webpage and this list.
But don't trust to much some newsarticles  and to avoid to become 
disappointed, don't expected to much.

As far as I understood is the Neo1973 based
on a mass market mobil (with windows mobil),
this explains the low price (compared with
other developer plattforms) but also that 
the Neo1973 team has some limitations what
hardware will be integrated on the one hand
and I think much stress and a deadline when
the hardware design for the first "production run"
is fixed. When you sell more then 100.000 devices, 
even a 10 Cent decision will sinificant.

I hope that some additional solderpoints could help
us to use the interfaces of the S3C2410 to
upgrade and extend the Neo1973 ourself.

Yes - as far as I know USB 1.1.

Ales> let us install some USB WiFi or Bluetooth adapter?
Yes - but USB 1.1 (max 12 Mbit/s) could be a little bit slow for 802.11b 
with 11 Mbit/s - AFAIK does have USB a protokoll overhead.
Even devices with official USB 2.0 like the Asus WL-500g deluxe does
have disappointing transpher performance...

Alessandro you has asked for the connector. Sean wrote me (on the list)
that it is no normal size femal connector - so I would expect that it
is a femal mini-USB-A conector and normal USB Bluetooth or WiFi adapters
would need an adapter.

According to 
www.linuxdevices.com/news/NS2986976174.html 
and other reports, the Neo1973 is based on Samsung S3C2410 system on a
chip:

http://www.samsung.com/Products/Semiconductor/MobileSoC/ApplicationProcessor/ARM9Series/S3C2410/2410UserManual.pdf

But consider, not every IO is used or acessable on the circuit board of
the Neo1973.


That Sean and FIC announced the Neo1973 before the hardwaredesin is finalized
could consumer makes wonder (hey, they anounced an unfinished
product.... I want to know more...) but on the other hand the
information about the high interest of Bluetooth and Wi-Fi connections
and the information and tipps about the Wi-Fi chip Marvell 88w8388 from
the OneLaptopPerChild project could help that there will be a device for
OpenMoko developing with the potential of Bluetooth and Wi-Fi. 
;)

But even without Wi-Fi AND Bluetooth the potential of the Neo1973 will
be amazing and it will be a great step forward - it is already a great
job of the OpenMoko team like Sean, Harald.... :)))
