4 Key Telecom Trends

Not sure what results you're seeing from Sprextel/Clearwire but the rest of the world is seeing them as horrible. I do however agree with you that both technologies will co-exist, just as TDMA and CDMA have.

I disagree with you on LTE being only in a lab. It's been proven to work and you will indeed see it in action by end of 2009 in a few markets. I also disagree with you on LTE being an evolution of UMTS. LTE is a WCDMA technology with nothing to do with UMTS.

4 Key Telecom Trends

I think folks forget about the existing spectrum held by the existing carriers as well. All we hear about is the difference between 700mhz and 2.5Ghz but forget that eventually the old 1.9Ghz and 800Mhz spectrum held by incumbents will eventually be used, negating the very small (if even what anyone would indeed consider) advantage of capacity.

Clearwire on WiMax vs. LTE: What War?

And yes, Verizon announced today (see RCR Wireless) that they will indeed launch LTE in markets in 2009....full steam ahead!

Clearwire on WiMax vs. LTE: What War?

Uh-oh, Clearwire backtracking already & saying they might even deploy LTE in the future! Scared?

Key Quotes from Agilent on WIMAX, Semi-conductors and China

That's because America is much smarter...we're waiting for LTE. Vodaphone seems to be behind it so I trust them a bit more than companies that are new.

Can WiMAX Triumph Over Its Competitors?

LTE is a new 4G technology & will not be controlled by the old 3GGP. It will, just like WiMax, be offered as an option as a built in accessory to computers. While Sprextel/Clearwire do have a ton of 2.5GHz spectrum, one forgets that once LTE launches on the newly acquired 700MHz, the carriers will be moving everyone over to LTE, which frees up their 850MHz & 1.9GHZ spectrum to be used as well. This will more than compensate for the 2.5 that the "new" Clearwire will have. The 700 & 850MHz spectrum in my humble opinion is more valuable for its penetration value than 2.5GHz is as well.

Can WiMAX Triumph Over Its Competitors?

Are you referring to VZW not taking the iPhone when offered (they were offered it first from Apple but turned it down, bringing in AT&T as a 2nd choice) as a "blunder?" I would keep an eye on the Blackberry Storm coming out next month & then we can revisit the reason why...that & the sheer number of consumers having issues with the supposed high speed network AT&T offers.

Can WiMAX Triumph Over Its Competitors?

Keep dreaming....

WiMax Empire Poses Continual Threat to the AT&T Network

Very good post contreras. My mistake on HSDPA using OFDM; going by what I was told from a friend at AT&T (I do know however as still a counterpoint to contention that it's a new technology that some applications of WiFi use it as well as even good old copper & DSL). Another subject not broached here is what will the actual Sprint customers use for 4G data on the existing network? I have not seen any talk of making the WiMax mobiles compatible with CDMA voice nor would I expect that since voice I'm sure will be offered by Clearwire over their network like it is currently (using a VOIP technology over their Expedience junk). Curious as to whether Sprint will go LTE like the rest of the carriers or even possibly go the "cheap" route & go UMB (which is the next iteration of EVDO; Rev. C I believe)? Thoughts?

WiMax Empire Poses Continual Threat to the AT&T Network

Not sure if WiMax will have that big of a headstart on LTE. Just read the latest article on Yahoo (regarding IDT) where they mention Clearwire's 1st four markets won't launch until next year...& again it's only four markets. You can bet that when Verizon & ATT launch LTE, it will go large scale & quickly overcome any "first to market" advantage WiMax has/had. LTE testing has already begun in sites so it's just a matter of a short time.

Enough said. Before you reply, yes I know EVERY carrier has disgruntled customers....but an entire site dedicated to it? WAY too funny!

WiMax Empire Poses Continual Threat to the AT&T Network

Bailey, didn't mean to argue numbers, I just based it on what was in the unbiased article/link I posted above. Every carrier seems to "overstate" their stats so that could be the case here. I do know (as well as everyone else) that Sprint has lost customers on an unheard of basis the last couple quarters which is never a good thing & is indicative of problems. Have no idea why they're leaving...doesn't really matter to me. They still left & my thinking is unhappiness.

WiMax Empire Poses Continual Threat to the AT&T Network

AT&T has HSDPA & they use OFDM in certain situations (i.e.-MIMO applications where used). Can be easily found on the internet.

WiMax Empire Poses Continual Threat to the AT&T Network

I don't believe anywhere on here I posted or disputed a post stating HSDPA was based/not based on WCDMA...that's already a known fact. Not sure where your statement on that came from. All I stated was that it used OFDM in some cases as well, since you stated Clearwire techs would have that advantage over other carriers in experience (i.e.-not true). It is also well known that LTE will use OFDM as well so again, not sure where that statement came from (I believe I already hinted at that in a previous post as well).

Have a great day!

We get them all the time...though I work on the network side. Not a problem, we'll probably end up buying what's left of "Sprextel" anyway soon!
