Well not yet but in a number of years anyways. Now, CDMA development will not happen for any US carrier with both Verizon Wireless and Sprint saying no to EV-DO Rev. C aka UMB. Looks like UMB is going to go the way of EV-DV.

nextel18m I'm waiting for you to chime in!

Well everyone knew this would happen that CDMA’s days were numbered in this country as companies try to go to 4G like Sprint with Wimax and Verizon with LTE. CDMA in this country will not go away for a long time though. Sprint will continue to fund its CDMA operations, it will take until 5 years before Voda and Verizon will do LTE. Glad that Verizon has finally moved to that 4G avenue.

CDMA development in this country will still go on and still fund but, in other countries, CDMA is still the favorite, however, many countries are also looking at Wimax and other technologies. I think CDMA will still be their backbone until they see that if they put all of the capacity (voice and data) on the next generation that it is better for them ...

Qualcomm actually controls many OFDM/A patents. So Qualcomm will be in this avenue as well as the CDMA and HSPA options.

I do not think it has to do with that as much but it is their focus to bring 4G technology to the marketplace to compete against HSPA and Wimax. on paper, LTE does not beat out HSPA, Wimax and UMB. (UMB= the technology they passed on.)

LTE is the next step after the HS*PA technologies. LTE is still in the very initial draft phases though and is probably at least a couple years out before its even ratified.

I am pretty sure that I read recently that the FCC mandated that all carriers will have to allow roaming from all other carriers (using the same technology of course) as long as the device does not harm the network. But there was no date that this had to go into affect and it might be in an appeals process or something.

Sep 21, 2007, 8:28 AM
The whole idea was to have a powerhouse company to doing one standard instead of both companies doing different things. It allows the costs to be a bit lower. Moreover, it allows for a seamless transition on that network in any of the assets they control.

I think we will see prices lower than $60 but it depends on the business model, but the problem is, is that people will pay for that mobility premium and if that continues they will continue to charge it.

But how are the wireless companies ever going to TRULY compete with the cable companies when they charge more. Isn't the point also to pose a threat to the internet business that cable companies have, I pay $40/mo.

I might actually be tempted to go wireless when the Sierra Wireless 880 comes out on AT&T.

Sep 21, 2007, 9:03 AM
With these types of technologies like LTE, Wimax, HSPA and others that are coming out the cost is not that much so they can obviously use their spectrum efficiently and provide higher speeds for lower price points. I doubt that, although it could happen, that those 4G+ technologies could beat out Verizon’s Fios, Comcast’s Power Boost, or any other type of high-speed cable offering (when it comes to price points and speed), however, anything is possible. The mobility factor is a huge premium. You are seeing Verizon’s FIOS spending becoming hefty now but soon the prices for the expansion will go down. It just depends how much the wireless company has paid for its spectrum, infrastructure, and other equipment and devices needed...

I don't think it'll be til 2010 til we see these impressive 4G speeds, but it sure will be exciting!!!

By the way, it'll be either the 1st of November, or the 15th of November that I'll have my credit card ZEROED out. And by the way, my credit score is all the way up to 728!!! That is so, so, so exciting especially considering not long ago it was 670. And considering I just made a $600 payment today, probably won't post until Tuesday though, my score will probably go up even more. And no, I haven't closed my Wells Fargo card, yet. Heck, I only have $27 left on that.

nextel18

Sep 21, 2007, 9:26 AM
We could see those speeds given the right spectrum efficiency and how the network handles it. MIMO is a very strong addition to those technologies and OFDM/A allows those speeds to happen. I think with Sprint’s Wimax could probably end up close to those speeds but I doubt they would actually release the ability to allow for them. As the years progress and ASPs and infrastructure goes down that allows companies to use their spectrum more efficiently. I do not think we will see the speeds because the wireless carriers in this country do not seem to want to release more spectrum onto the data side especially since it is very expensive to do so and because they care about their voice network more than their data. (Sprint cares about their d...

So what speeds have you experiences overseas? And where specifically?

The Sierra Wireless 880 is supposedly capable of 7.2 downlink, and 2.1 on the uplink.

Heck, I'd be happy if I can get more than 3mbps! But I've been having problems with my laptop recently, it's a Toshiba, and is now over 2y/o. IF I do get a new laptop, it won't be until March, and this time, I'm not spending as much as I did on this one ($1,100+)
I'm not going to spend more than $800, I can get a plenty find one for $800

Thanks for the respnse.

I am going to probably be going to China and Japan soon. Nevertheless, Australia was 2mb/s. France was 1.5mb/s. Norway was not too good; 1.0mb/s. Israel was 1.2mb/s. Switzerland was around 1mb/s. and UK was good at 2mb/s. I always go to many places overseas so those speeds might have changed but those were average speeds that I obtained. I did not remember what the bursts where.

On my current Sprint DO device, I have been getting also around 1.5 sometimes 1.8mb/s.

So I'm hooked on this 4G stuff now because I can see the potential. BUT isn't it kind of a slap in the face? VZ always boasting how much better (secure, reliable, etc.) and now deciding to go GSM? Are they saying CDMA isn't as good as GSM now? I always thought CDMA to be better (having experienced both networks). The data potential is amazing compared to where it is now, but how will this affect voice quality?

On a side note what is it with this credit score stuff? Mine sucks but everything I seem to do only makes a minimal impact.

I do not think it is a slap in the face but it is easier for Voda and Verizon to form one global LTE network by utilizing their assets. They realize that they must work together and if they have a global network and standard in LTE they should be dominate. I do not think LTE is good against UMB, but obviously, they think otherwise. I hope they change their current price points and restrictions or else especially in this country, they will not do well given their success or lack thereof in the EV-DO camp. I think if Voda went to UMB it would be able to happen but a lot harder. VZ is not going to be dropping their CDMA operations, as they still will operate well into the future from building the network to try to transfer the customers over. G...

GSM's 4G? I may be mistaken but I thought 4G was independent of the entire GSM/CDMA squabble.

As a technology, GSM is finished as soon as it can be replaced by a 3G technology. UMTS actually uses a CDMA air interface, although it is not identical to CDMA it uses the same principle. So in reality one could say that CDMA really took over GSM.

4G is the fourth generation (or step) of technology in the stepcase of mobile networks. 4G can come in many flavors, such as automobile engines (hybrids, gasoline, higher ethanol ones, vegetable oil, etc.) 4G will be defined by the result to the consumer, not the technical aspect of developing it.

That said, Qualcomm wishes to have a proprieta...

Yeah, as a technology I hear that LTE has more to do with OFDM and CDMA than anything else.

Considering that even at 3G (UMTS/WCDMA), the GSM upgrade path is already borrowing from the CDMA side on technology, it's more like GSM is going bye-bye, and the future convergence between the two camps is happening on the backs of the best technologies......

True dat. The lack of capacity, plus the hard hand-offs... it's nice that the future is gonna be built on something else.

Not just lack of capacity it is very expensive to run TDMA networks. That is why you see companies going to 4G networks shortly. Great capacity and cheaper to deploy and maintain.

Some of the comments here misunderstand the lay of the land in 3G/4G technologies.

In 3G, all systems are CDMA. The EU flavor of it is WCDMA (UMTS) and is used by AT&T. The US flavor of it, CDMA2000/EV-DO REV A and REV B, is used by Verizon and Sprint. Qualcomm has strong influence in the latter. However, they earn patent revenew from both.

In 4G standards, currently, there is no CDMA, it is going to be all OFDM/OFDMA. The EU flavor of it is called LTE. The US flavor, influenced by Qualcomm, is called UMB. There are some aspects of the 3G CDMA stuff in both. But, both technologies are completely different from current 3G stuff.

So, think of it this way, 3G means CDMA, 4G means OFDMA.

sangyup81

Sep 21, 2007, 10:12 AM
Yeah we weren't being technical. I know that all 3G is CDMA or W-CDMA based and that all 4G has some element of OFDMA and maybe some Single Carrier FDM but lets translate it this way

CDMA Family = CDMA, 3GPP2 (EV-DO), UMB
GSM Family = GSM, 3GPP (UMTS/W-CDMA), LTE

and or course WiMax is a whole 'nother thing.
