Vodephone, part owner of Verizon Wireless has stated it would want Verizon to move to world standard so Verizon can benefit from its ownership and have its customers roam on Verizon when they travel to the USA.

re: value of OEM phones. OEM/unloackled phones are extremely valuable when you travel to get local service instead of having to pay outrageous roaming fees. Can't do that with a locked phone and you have to pay your home network's outrageous roaming fees. non-OEM phones often havce fdeatures disabled, menus changed etc. (not the case for iphone though).]]> http://www.dslreports.com/forum/Re-CDMA-is-proprietary-and-has-no-future-Not-worth-the-effort-22936955 Fri, 28 Aug 2009 03:37:04 EDT Re: CDMA is proprietary and has no future.

Finally, while this may not have been overly obvious a few years ago, it is now obvious that CDMA is at the end of the road and has become a dead-end. Sprint and Verizon will not be able to evolve to a 4G version of CDMA, they will need to move to the world standard "GSM" for 4G.Not necessarily true. Verizon has stated that they will continue to use their CDMA/1xRTT network for voice as far out as 2020.

There's no reason to believe that Sprint won't adhere to a similar timetable. If Apple wants it, there is a viable market for a CDMA iPhone for the foreseeable future. Additionally, just this month, there have been upgrades released for the CDMA2000 specification to increase efficiency. It is now up to the carriers to decide whether they want to employ these upgrades to their existing networks or not. »www.cdg.org/news/press/2 ··· 7_09.asp

So it would be far easier to develop a GSM handset prototype than a CDMA one.
Easier perhaps, but it's certainly not inconceivable for Apple to make a CDMA version of the iPhone. Handset manufacturers such as Samsung, LG, HTC, Motorola, RIM, etc. do good business producing both GSM and CDMA phones. There is no reason why Apple can't as well.]]> http://www.dslreports.com/forum/Re-CDMA-is-proprietary-and-has-no-future-Not-worth-the-effort-22930921 Thu, 27 Aug 2009 02:49:00 EDT Re: CDMA is proprietary and has no future.

Two year contract? Yeah, so? If I just invested in a phone it's not likely I'm going to want to jump ship in the near future anyway!

Things are verrry different in other countries where you have a wide selection of GSM networks that your phone is compatible with, and you can go buy a SIM chip at any corner market. A $30 australian pay as you go plan got me through a very nice week's worth of data and voice.

First, there is a difference between cdma and CDMA. "cdma" is a technique/philosophy to handle collisions on shared medium. "CDMA" is a proprietary network implementation owned by Qualcomm Corp which charges royalties for use of its network stack. That means that every handset manufactured that support's Qualcomm's proprietary protrocol sees parts iof its revenues flow to Qualcomm (aka: less profits for manufacturer and network).

Also, 3G GSM, instead of using tdma, uses cdma philosophy. Its implementation is called wcdma, to differentiate it from CDMA2000 which is Qualcomm's proprietary imkplementation for 3G.

Apple would have also seen Nokia's legal problems with Qualcomm with Qualcomm suing Nokia for stupid reasons, and Nokia in the end no longer making phones for Qualcomm's CDMA. Qualcomm should have learned not to sue its customers.

Finally, while this may not have been overly obvious a few years ago, it is now obvious that CDMA is at the end of the road and has become a dead-end. Sprint and Verizon will not be able to evolve to a 4G version of CDMA, they will need to move to the world standard "GSM" for 4G.

It is not a given that Apple would have actually manufactured even a prototype CDMA phone. That would have required that they sign agreements with Qualcomm to get the specs and chips/software to operate on a CDMA network. With GSM, you pay a flat fee for the documentation of the stack, and there are no royalties to pay for each handset.

So it would be far easier to develop a GSM handset prototype than a CDMA one.

Personally, I await availability of reasonably priced unlocked (as in: OEM, never locked) iphones before I buy one. Flying to europe to buy one is a bit too pricey for me :-)]]> http://www.dslreports.com/forum/CDMA-is-proprietary-and-has-no-future-Not-worth-the-effort-22930458 Wed, 26 Aug 2009 23:53:25 EDT
