Shiva Bandaru 0 Report post Posted December 29, 2005 (edited) Today I Found Intresting Story about CDMA future On GIZMODO.COM (scoop site related to latest Gizmos and technology) ............................. CDMA Dead? Carriers May Switch Standards Siemens, makers of GSM switching hardware and, in conjunction with BenQ, GSM phones, is saying that CDMA is on its way out in North America. Ummmm… Right. According to the peeps over at Siemens, more carriers are looking to migrate to the standard GSM networks instead of using CDMA. With market share of CDMA declining more and more every year, companies are looking to GSM for an answer. Numbers may or may not lie, but Sprint and Verizon ain’t going anywhere, that’s for sure. In related news, Coke execs said that Pepsi causes massive cramping and Apple says that Spain is going PowerPC all the way, eschewing Intel completely. ................................... COMENTS yea, not so sure i believe this statement either.. since the CDMA based carriers are the only one's with a high-speed (3Gish) data networks too.. where as Cingular just implemented and started to rollout their highspeed cell data and tmobile.. well.. tmobile is always behind... plus, how happy is your average US Joe/Jane gonna be when they are told that the new $300 phone they bought for xmas is no longer going to work since the carrier is changing to GSM?? by seamonkey420 on 12/15/05 11:47 AM AT&T switched to GSM. Southwest Bell switched to GSM. Nobody has switched to CDMA. It all comes down to market share. GSM has 77.6% of the market, which means the cool phones (e.g. RAZR) and the feature-rich phones (Treo, P910) come out for GSM first, CDMA months or years later, or never. Then there are the business travelers. Most want hassle-free international coverage, which means GSM. So as the cellphone market in the US starts to get more sophisticated, that's going to put CDMA operators at a severe disadvantage. I recently switched cell provider, but I didn't even consider Verizon because of their niche technology. by mathew on 12/15/05 01:47 PM neither sprint or verizon will be switching to GSM. GSM is more dead than CDMA. (and yes, my dad can beat up your dad) Both standards will converge in the near future into UTMS or WCDMA or whatever you want to call it. Eventually there will be one standard and less than a handful of providers, making the whole expirence more "global". And that's what we as consumers really want, right? by non-meat-stick on 12/15/05 01:48 PM I would like to believe that this Siemen's individual's words were taken out of context. Siemen's recently layed off a bunch of their handset division - a division that made GSM phones. There have been no recent advances in GSM technology - just cheaper and smaller chipsets. So GSM (as a standard) has peaked - the installed base is huge, but there's not much use for new equipment. Siemens, OTOH does a good business making 3G infrastructure equipment (UMTS/HSDPA) and is fully committed to the growth of WCDMA. I would like to believe that the individual was actually talking about the battle between 3GPP (WCDMA) and 3GPP2 (CDMA). "I would not bet on North America continuing with CDMA. CDMA is losing market share globally as the new mobile phone users live mostly in the areas where GSM is the leading technology." Worldwide, CDMA has a smaller installed base than GSM. But GSM itself has hit the end of the road and is being replaced by WCDMA. So I would disagree that CDMA is losing marketshare - it just isn't growing as fast as GSM/WCDMA (which you can argue is losing). However, WCDMA and CDMA, as evidenced by their acronyms, have commonality in their principles and have similar benefits for the carriers (though they will never merge). WCDMA, by its nature, will likely win-out in terms of throughput (even in NA), but don't count on CDMA disappearing. And in the end, Qualcomm holds the patents on the technology, so all the royalties come back to the same entity regardless of which technology "wins". China is among the markets where the company is active. Catselitz expects China to issue third generation (3G) licenses in several stages, starting early next year. "I believe China's 3G licenses will be given in the early part of 2006; it could be the first quarter," he said. China is expected to spend more than $10 billion to set up its 3G networks after licenses are awarded. As for China, don't hold your breath. A year ago I was in Hong Kong hearing the same statement - just swap 2005 for 2006. I'm convinced that China will not issue any 3G licenses until they (chinese infrastructure/chipset/handset designers) have perfected TD-SCDMA. China naturally does not want non-Chinese vendors to overrun its potential to service itself with its own infrastructure. It might give the NA/EU infrastructure companies "close" to equal access, but expect China to grant licenses only after they're ready to compete with TD-SCDMA equipment of similar performance, based on Chinese IP. Why give your money to another country when you can stall long enough to pay yourself? But again, Qualcomm is on the hunt for royalties from any TD-SCDMA development - and they'll actively persue them and take the cut they think they deserve. by skip on 12/15/05 01:50 PM Sorry non-meat-stick, but the two will never converge. They will overlay and some carriers may switch from one to the other (from CDMA to WCDMA) but though the two will not unite, they are not completely dissimilar. WCDMA is 5MHz wide, CDMA is 1MHz, and each with different channel spacing. The codes they use for spreading are different, synchronization between basestations is differrent, and those are fundamental differences. WCDMA is designed to "nicely" replace GSM coverage, whereas CDMA will not. But at the moment CDMA (EVDO), while losing on theoretical throughput, gives best real-world throughput. Expect that to change as higher-speed HSDPA (WCDMA) handsets come on the market. South Korea, which has been a CDMA-only environment, appears to be migrating to HSDPA, so in that sense WCDMA might be winning over CDMA, but nobody is losing to GSM. As for a "global" experience, expect chipsets that support both CDMA and WCDMA to appear sometime in the future, and in handsets 9 months later. by skip on 12/15/05 02:05 PM Full story Will U.S. carriers switch mobile standards?

Ramchi 0 Report post Posted December 29, 2005 My understanding goes that both GSM and CDMA will be replaced with 3G soon. I am not a telecom network expert but in this forum I hear people saying CDMA can be converted to 3G network easily compared to GSM networks. GSM market share is mostly due to variety of handset options. In this respect CDMA is lagging behind forcing GSM network to capture more market share.

Everyone says that CDMA is better in 1. Better voice clarify 2. Fewer Drop calls 3. Better security due to strong encoding 4. Advanced features 5. Better voice quality etc....

ashoksoft 83 Report post Posted December 30, 2005 well ... 3G ... Since I work with a company that deals exclusively with 3G network *yeah the name of the company is also 3 ... a part of the Hutchison Wampoa group... I will get some details out.. 3G is generally a term reserved for phone networks which allow video calling or high rate apps transfer... mostly on WCDMA (2100 Mhz is what 3 operates at.) 3G network is real strong ... with cross pole support (which is a term where non-overlapping bases can cover a longer range)...... 3G network also allows GPS streaming to be done .. using hardware like the Route 66 GPS. Btw WCDMA is more related to GSM compared to CDMA (except for the name)... and yes CDMA networks (as we have here) are CDMA2000-1x which is compitable with video transmission .. hence the belief.

Ramchi 0 Report post Posted December 30, 2005 Is it not true that CDMA and its successors are the real future since they support Voice + Data + video? Is not again true that GSM may be strong in Voice but lags behind in Data/Video streamings? Share this post Link to post Share on other sites

If you "really" search around hard on the Internet, you'll find "convincing" articles "proving" that George Bush is really an Afro-American ... got his skin transplanted, all over his body ! (.... meaning to say, I am not convinced by the article you have quoted) Anyway, in my view, GSM works .... simply because it's GOOD ENOUGH, even though CDMA is BETTER than GSM. GSM guzzles 5 times more spectrum than CDMA ..... spectrum is scarce .... but still the fact is that the spectrum is not so limited, to effective kill the economic viability of GSM. So, inspite of GSM being a weaker technology (in strictly technical terms), CDMA and GSM both compete effectively with each other. (eg. in India, despite everything, both technologies, in the end, compete on price ..... and neither seems to be bowing out of competition). Lack of video streaming capability hurts 2G GSM, a lot. And it's transition to 3G WCDMA is very costly .... nearly, building something from scratch (.... all old GSM towers go practically waste -- you need entirely new equipment). CDMA 2000 upgrades to EVDO far more easily (... lesses investment in add-on equipment). But I don't think either India or China is moving that fast into 3G (either GSM or CDMA based). Both 2G technologies GSM and CDMA will be widespread. Edited December 30, 2005 by SexyGurl Share this post Link to post Share on other sites

Ramchi 0 Report post Posted January 1, 2006 (edited) Again big confusion! When they say 3G, whether it means UMTS(HSDPA) or WCDMA? After reading the edited post the confusion is increasing. WCDMA is said to be GSM friendly network which means existing CDMA networks may find it difficult to implement it. Does this mean existing CDMA networks will be upgraded to UMTS mode? THe most important question, there are many 3G phones in the market, whether these phones can be operated in both these network simultaneously? Which one is good between UMTS & WCDMA ? Edited January 1, 2006 by Ramchi Share this post Link to post Share on other sites
Shiva Bandaru 0 Report post Posted January 2, 2006 UMTS(HSDPA) is better technology and cheaper then WCDMA. allmost all new 3G phones (GSM) supports UMTS/CDMA/GSM Triband(eg SE P990, NOKIA E series) I Think most of Cdma phones avilable in india are not 3G phones. they are just basic phones dumped to india at very low prices to operators (most of phone models are OLD STOCK/ OUT DATED/FAILED in N/S america). Once Number portability & 3G Is Finalised in INDIA, CDMA operators may lose customers. Share this post Link to post Share on other sites
Ramchi 0 Report post Posted January 2, 2006 Nokia N series are WCDMA. E Series have not hit the market yet. All existing 3G phones in India are WCDMA and only I have seen one SE Z800i phone using UMTS mode. Regarding old mobile phones getting dumped may be true but not true for new models such as Nokia 6255 because these models never existed before in US markets. Also, companies like Reliance/Tata Indicom instead of focusing on improving their network unnecessarily manhandling instruments and stripping its features.

Shiva Bandaru 0 Report post Posted January 2, 2006 Also, companies like Reliance/Tata Indicom instead of focusing on improving their network unnecessarily manhandling instruments and stripping its features. I agree with you . IN GSM we have lot of choices - Good Handsets (we have 100% ownership), Different Carriers, Always on GPRS, WAP and more value added services..... Most of Cdma users are newbies. they mainly use it for incoming calls and sparely use for outgoing . With Lifetime offers by GSM operators ,and low priced handsets, newbies like GSM then CDMA. The main adwantage of CDMA is DATA capability. Both Reliance/Tata charges VERY HIGH rates for Internet/data usage. Their new schemes discourages data users. BSNL DATAONE is more cheaper then these CDMA operators (400mb unlimited - 250, 2Gb Unlimited - 700) I Think BAD TIMES ahead for CDMA. Share this post Link to post Share on other sites
Arun 795 Report post Posted January 2, 2006 When broadband providers are on the increase, R-Connect doesn't have any place for home users unless there isn't any broadband providers around. But with the increase in laptops, R-Connect is the default choice for many for wireless connectivity. And it it "good times" ahead for CDMA with EV-DO coming soon later this year hopefully !

And it it "good times" ahead for CDMA with EV-DO coming soon later this year hopefully ! EV-DO handsets are very very costly and must bound to operator . (is we have 100% ownership of handset?) I Think it is not good to buy Hi-End phones in CDMA because we are not alowed to use it on another Cdma networks. With 3G , GSM operators capable to offer Hi-Speed Internet to its users. CDMA is best for Limited Mobility/FWP area where AIRTEL also offers GSM Fixed wireless phones with SIM in some areas. There are TOUGH Times Ahead For CDMA in INDIA.

Ramchi 0 Report post Posted January 6, 2006 I must concur Shiva on limitations in Handset options under CDMA. I do own Nokia 6255 but there is no way I can use if other than Reliance though different Nokia 6255 works fine with Tata Indicom. To survive CDMA providers must think about long term plans this is one of the reasons why I have said some time back in this forum that CDMA operators are probably against 3G coming out quickly. They may use all kind of tactics to delay this spectrum allotment. Share this post Link to post Share on other sites
