My boss has tasked me with researching the GSM and CDMA protocols.
Does anyone know of any non-biased sites that provides such a
comparison? Our company is ready to spend a large chunk of money on
cellphone/PDAs and we want to make sure we choose the best network --
and hopefully the one that will become the real standard of cell
communications.
Thanks,
Scott

No, this is a religious issue. There is no such thing as non-biased.

Best advice I can give: Ignore the standard. Research what the service and
phones will do for you and your company. Make a list of what's important
to your company and find out how well the different carriers satisfy your
needs and at what cost.

The only thing that at present is stopping me from going from GSM to
CDMA is the lack of CDMA SIM card in the country that I live in. I
see that SIM cards are a part of the CDMA standard but Telecom NZ no
doubt to stop parallel importing bought the one with out them..

What happens when you phone dies. Completed reprogram of a new
one???? Reminds me of the bad old days of AMPs when it was back to
square one every time you changed your phone..

When you get a new phone, you can have the phone book and such
transferred to the new phone (if the old one is still functional). It's
standard practice these days at Verizon Wireless, and I assume also so
for the other CDMA providers.

Nearly every CDMA handset I have seen synchs with .csv files, exported
from Outlook, Act, etc. It is fast and costs next to nothing. For
example, check out www.datapilot.com I switch CDMA handsets 2x -3x /
year and have never lost any of my 200+ contacts or calendar entries.
With 2.4Mbps EVDO now out I expect that this will all be a SSL site -
wireless synch eliminating the need for cables and SIM cards.

That's fine if you have this stuff to do it with but the average cell
phone user wants to be able to update their phone with minimal fuss
hence the beauty of the GSM SIM card. No contacting your carrier to
get the new ESN matched to a cell phone number or having the phone
namd with a new number. I'm not sure how they do that on a CDMA
network.. Also you can go to another country with GSM , buy a prepay
SIM and have service with out paying a bucket for roaming. I find
the CDMA technology far better than GSM but until the carriers add the
SIM card to CDMA the company I work for won't be going down that
road..

I think it's the same for South Korea. If you live in Canada and have a
SIM card, you can use the same GSM SIM card in the local CDMA phones.

I mean you can use a Rogers GSM SIM card in the Korean CDMA phones.
Sorry for the confusion. Here is some information from the Fido website.
"Roaming in Korea
For roaming in South Korea, all you need to do is pick up a special CDMA
rental handset at the airport when you arrive. Simply insert your Fido
smart card in the rented handset, and it's just like roaming in any
other country.
For more information on roaming in Korea or to a reserve a rental
handset on line, visit KT Freetel or SK Telecom."
"Roaming in Japan
Travelling to Japan? Fido offers roaming on two W-CDMA (3G) networks in
Japan: Vodafone and NTT DoCoMo. To roam on one of these networks, all
you need is your Fido smart card and a W-CDMA handset. These special
handsets are available for rental at Tokyo's Narita airport or Osaka's
Kansai airport. Don't forget to bring your Fido smart card with you when
you go!
For more information on roaming in Japan or to reserve a handset
on-line, visit Vodafone or NTT DoCoMo."
