cdma2000 is a true evolution of an existing network. Using the same network core, same cell sites, same spectrum, and only minor software and hardware upgrades a 1x network can be converted to 1xEV-DO. |
|
Because its only 1 network and 1 standard it is completely backwards compatible. This eliminates any coverage concerns such as thosed experienced by FOMA users in Japan. |
|
That being said this is were GSM operators stand. No matter what path they choose they have to build a parallel network overtop of what they already have. |

You know that any launch of new features will have its glitches. Bell's 1x network launch wasn't completely bug free.

Yes, NTT DoCoMo has done a great job of proving the benefits of WCMDA as they get clobbered by the competition as as nearly every single GSM provider continues to push back their 3G aspirations. |

Originally posted by ImmerStark european carrier shelled out a total of 30 billion euros for their umts spectrum and now any can not afford to build out their networks by the deadline set in their agreement to purchase the spectrum, some european carriers have even forfeited their spectrum because they could not follow up and build out the networks. in japan ntt docomo has a very limited wcdma network with only a few more than 100k subscribers signed up in the past year, there has been a recall of almost every handset launched for use on it, and they are failing so bad they are rushing the guys in the lab to make 4g deployable by 2010 so they can move on past their wcdma blunder, and the idiots are planning on using a 4g technolgy that requires an ungodly ammount of spectrum(100MHz of contiguous spectrum to be exact). the only reason j-phone is launching wcdma is because they are owned by VODAPHONE, big surprise there. kddi has signed up millions of 3g cdma2000 subscibers in only the past few months and is enjoying unrivaled success. i have no problem with voice quality on my cdma phone, it is as good as a land line, and the background noise supression is a blessing to everyone i talk to. cdma2000 in independant test run in china has higher data and voice capacity than wcdma |

Sorry, I meant to say in the US. Also, the W-CDMA system in Japan only covers very limited metro areas. |

By the way, choosing CDMA does not cut you off from the world. Check out au service in Japan. They offer roaming in many popular international destinations such as canada, us, korea, china, etc etc. I bet you only 0.05% of people using GSM actually need it to roam all over the world. Most people usually just need to go back and forth between a few destinations and CDMA will soon have many of the north american, south american, asian, and australian markets covered and eventually we will see roaming available to Canadian and US clients. Also, if the network chooses to they can offer SIM cards to cdma clients that they can take overseas and put in GSM phone if necessary. It very narrow minded to think that choosing cdma is cutting yourself off from the world. |
CDMA is cutting yourself off when already 160 countries use GSM. 747 million subscribers chose it for a reason, andthe number is still growing at an exponential rate.

Originally posted by MethodMan With the current amount of GSM providers, they are no way near exhausting their current capacity. They haven't even implemented UMTS yet. |
| The current cdma providers are forcing most phones to use an EVRC codec. This is to provide more capacity but at the cost of voice quality. |
| No kidding sherlock. Given that business users are centered in and around the metropolitan and have the wherewithal for such a network there's no point for a massive countrywide rollout. Give them a year and the masses will flock to the wonders of UMTS. |

If Verizon had any business sense then they will know that accepting a worldwide standard will be benecial to themselves. Jumping to cdma2k effectively closes off the world, stymies revenue generation and will lead to utter dissappointment. Some carriers here in N.america that have went the 1x route are still ironing out bugs. No network upgade is immune. Deployment of UMTS is well underway and NTT will net the subscribers needed to generate profit and surpass all expectations.

Why would they even bother? There must be value in roaming worldwide or why else would they bother. |
|
CDMA has always been about keeping control of its clients. From the lack of countries supporting cdma to the lack of sim-capable phones. Seems like the carriers want to lock their subscribers in. Was this intentionally designed from the ground up? You've even chalked up the sim card idea as a bad design since it'll mean a loss to providers on phone subsidies. You know the situation in Canada. You don't even see the same phones between the two cdma providers. You can't even switch between CDMA providers without buying a new phone. Telus west is an exception(and a hassle at best) but how many other cdma providers will follow suit? |

|
Originally posted by Xirc You don't get it. Some CDMA carriers will provide customers with a SIM that they can put in phones overseas to roam. Do you know what this does? It eliminated the clients need for GSM where the client lives. Hence the client can choose CDMA because its the best here and can still enjoy roaming benefits overseas. |
|
This is not a good thing for GSM because it marginalizes the one big differentiating benefit that many people tout...roaming! It also works the other way around. If you're a CDMA carrier and you let foreign customers put a SIM in your CDMA phone then you get to bill for the roaming charges. The CDMA carrier is making money. Again, this marginalizes GSM. |
|
Look at it this way. Say I'm a GSM user in Canada and I have a single or dual band phone. If I want to roam overseas I probably would have to buy a new tri or dual band phone. |
|
If I'm a CDMA user and my carrier gives me a SIM I can take it overseas and put it in a cheap dual or tri band phone. |
|
Suddenly, the benefits of having GSM here in Canada are getting smaller and smaller. This is the way the technology is moving. CDMA carriers might not put SIM chips in their own phones, but they will be providing the chips to clients so they can roam overseas. |
|
What this means is that North American CDMA carriers will be able to offer the best of both worlds. GSM carriers? Nope
