I am sure you are right as you sure know a lot more about the subject
than I do. However, I have seen two things that I would appreciate
your opinion on.

In a previous series of postings in this news group, Cliff posted a
message that included a setup he uses in his motorhome. See
http://www.cj-and-m.com/HomePage/WiFi_Setup.html He is apparently
using a KPC650 wireless broadband aircard to feed an Internet
connection to a Kyocera KR-1 mobile router.

Please also refer to http://www.kyocera-wireless.com/kr1-router/
This apparently indicates that the wireless broadband KPC650 aircard
may be used to feed an Internet connection to the KR-1 router.

I read the specs and they are as follows

# WAN Interface:
1xEV-DO PC Card or 1xEV-DO USB phone*

# Compatible with the following 1xEV-DO Rev A. Devices:
Kyocera KPC680, Novatel S720, Novatel U720, Pantech PX-500

# Compatible with the following 32 bit 1xEV-DO Rel. 0 Type II PCMCIA
Cards:
Kyocera KPC650, Novatel V620, Sierra AC580, Sierra AC5220, UTStarCom
PC-5740

# Compatible with the following 1xEV-DO USB phones:
Kyocera KX18, Samsung A890, Samsung A900, Samsung A920, Sanyo 7500

You will see that the USB device you have IS NOT on USB compatabilty
list.


What I want is virtually identical. The KPC650 is a PCMCIA card. The
KPC650 works well in this application. My application is exactly
identical except I have a USB720 instead of the KPC650. If a PCMCIA
card can feed an Internet connection to a router, why not a USB
port? Actually, the KR-1 will accept an Internet connection via a
USB port from a cell phone. Why not my USB720?

Dave, this router obviously has hardware that provides virtualzation
of connection. Also, most of these AirCards are PCMCIA CardBus devices
which are in effect a plugged in PCI device and because of the socket
standards used for this, it is easier to virtulize the connection
across it. When you deal with specailized hardware like the KR-1
mobile router, you have to stick to the exact hardware supported
because virtulizing the network connection like this across a USB port
into a router is not a normal industry standard PnP option. As I see
it, you have two choices, either get a cheap laptop/PC thats only
fuction is to interface with USB wireless modem and then share it back
to router via NAT(and this can be a older unit with WIN 2000 or XP on
it and it does not need a lot of speed either if it is only acting as
a "router") The second choice is to buy a wireless network modem that
is comapatible with KR-1. Many years ago I used to do some trade tech
shows and I used to use cellular access to intenet for 10 to 12 hours
at a time (yes that long). I used a PC to act of point machine or
proxy for the access and then client machines could share it. There
was not a lot of bandwidth to play with then but it worked fine for
E-mails and on line chats and such during shows and a online database
lookup related to bussiness. Back then I had a cell phone acting as
modem plugged into the main PC. I used a 11 element highly directional
Yaga antenna too. It was slow but very reliable and back when I was
doing it in mid and late 90's it was kinda virgin territory. Around
2000 I went to a digital phone and used it for a few years until I
stopped doing shows. That one was a old Qualcomm 860 which was a good
phone for this as you could use a very large external battery on it
that could run phone for 8 to 10 hours on line like this and I had a
hacked (of sorts) 28.8 K connection too instead of the noraml 14.4 K
wireless digital data rate then. (in my earlier days I used a 3 watt
bag phone with a external power supply) I had a deal where my airtime
for these events was free too.This was all on AIrTouch/Verizon.
