Re: I wonder...
muchdrama said:
All that effort, and you expect us to believe that Sprint decided it simply wasn't in their best interests?
Yeah, right.
I'm inclined to agree with muchdrama here. I suspect they sought to multiple paths to acquire additional spectrum. The MMDS path succeeded, they don't need spectrumco anymore.
I think this is a mistake though. Sprint's alliance with the cable operators could realy facillitate the promotion of femptocells (personal base stations that are tied to dsl/cable division and have wifi and ...
Re: I wonder...
muchdrama said:
...why that played out the way it did if they needed more spectrum?
They've secured a lot of spectrum via their agreements with clearwire. They have almost 100 Mhz of MMDS spectrum in some markets.
That said, that spectrum is less than optimum. 2.5 GHz no give such good coverage which is why they are pushing mimo and other antenna techniques down the component food chain.
But i also believe that the the spectrumco created a conflict of interest.
Sprint has consistently ...
How Long Did That Take?
Was that 5 years from GSM launch to complete TDMA shutdown?
Its amazing how long these things take. I wonder how long it will take sprint to shut down iden. I bet that'll be around 5 years.
Re: Why WiMax when "3g" doesn't even work like "3g"?
Sprint Didn't take a chance on data they took a chance on a voice platform (CDMA) that maybe someday would be slightly more useful than GSM if people ever wanted data. It was about voice capacity not data.
CDMA was badly overhyped but it did in fact prove to have an advantage lver GSM for voice once the korean's helped solve the breathing cell issue.
With WiMAX its a different game. It has NO...NONE...zilcho...zero advantage over EV-DO Rev b and ...
Re: Why WiMax when "3g" doesn't even work like "3g"?
One of the FCC's requirements on the Sprint-Nextel merger was employ of their 2.5 GHz spectrum (both nextel and sprint had a lot) to cover I believe around 20-30 million persons by 2008.
Reason two. The sprint-nextel merger is a fiasco. Sprint has purged nextel and really pissed off the nextel subscriber base. Just look at their retention rates and new adds..not good. So rather than improve the basics, the Sprint executives are deploying their executive hype parachutes and pushing ...

This is going to be huge...
A huge fiasco or maybe just substantial BS.
Sprint choose a mobile technology that does not work. Now why would they do that?
1) Sprint executives need something to distract from their miserable performance overall and the horror the nextel merger has become.
2) WiMAX powerpoints say wimax will one day support TDD and FDD and OFDM mobility. They are the only ones doing that.
3) Sprint has a FCC imposed timetable. they must deploy a little ...

Roadkill said:
You mean besides the fact that each tower has 10 times the range of conventional cell towers?
In theory, most major metropolitan areas could be covered by no more than 5 towers.
At any rate, WiMax is still under development. I find it odd that carriers are talking about deploying it this early in its life, but hey I guess that announcing phones a year before they're ready isn't far enough in advance for them any more.
Roadkill,
This is faulty ...
Re: This is interesting...
Roadkill said:
WiMax != CDMA
WiMax is far easier to deploy than conventional cell towers, so Nokia may be planning on making WiMax-only handsets in the hope that Sprint (or some other carrier) will deploy it widely enough to make those handsets practical.
No not at all. In fact if WiMAX is incapable of a n=1 reuse (use every frequecy in every cell) then its will be a lot more difficult to deploy for sprint than a cdma upgrade. My understanding is ...
Tired of Vendor Politics
That is what this is really about. The operators have formed that group to basically get some influence over the standards process, which has been vendor driven and inefficient.
The operators are sending a message to the vendors: "cut the crap or we will."
Their intent is to influence standards groups. I have not heard of an intent to actually start their own tech.
They could, however, do the latter by commercializing an existing tech and the two front runners have ...
Its about simplifying the core network
Carriers in general want to free themselves of their costly, proprietary, and difficult to maintain and upgrade core network. They want an IP core because its cheaper, easy to write apps for and because one core type can support multiple services (like voice, data, wireless, landline voice, and even cable TV.).
VoIP can give very good quality provided voice traffic is prioritized. If you control the network (regardless if its cable, wireless, or copper cable)then you can priortize traffic. ...
Re: ok now thats bad ass
I agree. That thing looks good. That phone with a fastap keyboard would simply kill.
tax and spend republicans strike again
What ever can we do with these tax and spend republicans. As if its not bad enough that they are destroying the US economy with their debt, support for outsourcing, destruction of the value of the dollar (low....interest rates), payola corporate welfare and corporate welfare "defense" contracts now they want to scew the wireless industry.
Tax and spend republicans, they're killing the nation.
Re: It's a fistfight for 4g!
muchdrama said:
It's a fistfight for 4g!
Yes indeed and in contrast to what the wimax camp wants you to believe.
IP Wireless has had numerous commercial networks since 2002 i believe. They are all pretty much for fixed wireless and latency is supposedly a problem, meaning voip would be a problem. Its part of UMTS though and it can improve.
I think sprint will go with IP Wireless (UMTS TDD or TD-CDMA) or with Flarion/qualcomm's FLASH-OFDM. The latter is furthest ...
More Iden?
I kind of thought the idea was to migrate current iden users to cdma, not build up more iden coverage.
Sprint will send a message if they really build out more iden. That message is that iden is going to be around for quite some time.
Its probably not going to be all that easy to migrate iden customers and sprint may have realized that. They might also realize that iden needs better coverage in the short term. There are ...
Re: Power Vision not so powerful
KillaCan715 said:
I can't believe you are assuming that because VZW's EV-DO blows that Sprints would as well. How many times have they released their PTT now....3? They hope to release their TV next year as Sprint allows you to watch movies and TV shows like the new iPods do. I take it you have never seen Sprints "Live TV". I can sit and watch NFL network live on my a940. It kinda sux though because ...
Re: Power Vision not so powerful
danbfree said:
You guys are all full of it. Sprint WANTS people to use the damn service, moron. Why would you claim all of this on Sprint just because VZW does this? VZW doesn't have as much riding on data as does Sprint. VZW has lots of blindly loyal customers that they can work over. Sprint wants and needs people to use their EVDO. Their is plenty of bandwidth for all, just face it and quit being a blind hater!

Power Vision not so powerful
how long will it take before sprint starts puting restrictions on this service. Downloading a movie is a subtantial amount of data and ev-do (AKA: powervision) is pretty restricted in throughput.
We've already seen the "power" of ev-do via the verizon experience. Verizon are now turning people off who use ev-do too much, which does not seem too difficult with all the conditions verizon puts on it.
Re: UMTS/HSPDA/EVDO begone!
Bugwart said:
Everyone posting here seems to think that WiMAX will only succeed if it is adopted by one of the major cellular companies. I would question why they would need to be involved? To install infrastructure? Why?
WiFi is a success because people use it. WiMAX will be a success for the same reason.
Wifi is cheap and it operates in unlicensed 2.4 GHz and often unlicensed 5-6 GHz spectrum.Its mainly in 2.4.
WiMAX will certify product at 2.5, 3.5, and 5.8 ...
Re: UMTS/HSPDA/EVDO begone!
My money would be on flash-ofdm but i would not rule out super 3g (umts long term evolution)or 802.16e in the future. They might have something five years from now. UMTS TDD (ip wireless) looks like they'll score some nice contracts as well.
I doubt td-scdma will gain traction outside of china. The official version, which is the one all the major vendors support, uses the same expensive, proprietary and IP unfriendly core network as wcdma. No one wants that. ...
Re: UMTS/HSPDA/EVDO begone!
I have considerable doubts about performance of wimax. Mobility is very difficult to do efficiently and with high QoS. Add VoIP to the mix and it just gets tougher. There several amendments to the fixed version of wimax (802.16d). I think we'll see the same for 802.16e and even then i am skeptical.
FLASH-OFDM has frequency hoping on top of ofdm and that might make the real difference. Traditional OFDMA means lots and lots of tones (transmissions) which will ...
Re: UMTS/HSPDA/EVDO begone!
"deploy technologies on their 2.5ghz spectrum over 4 years offering service to AT LEAST 15 million people and then cover 30 million in 6 years."
Is that it? Hmm. I'm still skeptical about wimax and sprint and wimax and anyone else but you could cover 15 million people pretty quickly and for less than murderous cost by deploying in NYC (five burrows).
Re: UMTS/HSPDA/EVDO begone!
In the US the carrier to watch is sprint-nextel who must do something with that MMDS spectrum they have covering 80% of US residents within four years. It is a condition of their merger.
That four year deadline strongly suggests that they'll do UMTS TDD (IP Wireless) or FLASH-OFDM because both of those work now. Of those only Flash ofdm offers proven mobility and proven mobile voip so I'd guess FLASH-OFDM.
In europe the one to watch is T-mobile who has ...
WiMAX will Die a Painful Death
It is going to take another 3-4 years to produce stable wimax gear which is interoperable and actually mobile. My personal guess is that it might take longer. the 802.16e spec was rushed through by intel really and like every other paper standard, i guarantee it will not work without changes. Amendments take more time and mobility is not so easy, especially when your group is driven by firms with little mobile experience like intel.
In the meantime, the world ...
Re: *Curious
I'm pretty sure WiMAX will not be the choice. Sprint-nextel are supposed to do something with that spectrum (2.5 GHz) sometime within 3-4 years time.
They have been very clear in their desire for full mobility and voip over mobility. The mobile wimax spec is not even done yet and I can guarantee that its going to be a lot harder and slower to implement well than wimax proponents want you to believe.
Mobility is pretty complex and doing ...
Re: *Curious
Companies have long been unhappy with 3G but the tests are really about something else.
Sprint-Nextel have a lot of spectrum up at 2.5 ghz and that creates opportunities for new services so they are looking for a technology that will enable them to do more than mobile voice and tiny bits of data.
They want to be able to offer DSL-like services in areas with low population density, true enterprise class mobile data services (ev-do, hsdpa don't do this ...
Re: *Curious
muchdrama said:
"This move does not appear to be an indication that Sprint has chosen UMTS TDD over any other technology."
It doesn't? Seems like it to me.
Sprint is pretty much testing everything. They are also working with samsung to test WiBro (a WiMAX derivative) and Motorola to test 802.16e (mobile wimax someday). Sprint is just being thorough and they are probably making sure every vendor knows they have other options.
I don't think they'll do UMTS TDD unless there are ...
WiBro Is WiMAX
Wibro is based on an early draft of 802.16e. the intention has always been to unify the two.
The important difference is that wibro might end up being an option within 802.16e, an advanced option. Also relevant is that samsung is ahead of the rest of the 802.16e pact but they are still probably behind FLASH-OFDM.
Sprint is going to try everything, and they will play samsung, motorola and qualcomm (who now owns flarion/flash-ofdm) against each other.
No Risk - No Reward
Sprint and the rest of the US operators have played it safe for a long time. That is the nature of the game of a national operator of course but consolidation may mean less risk taking overall.
That presents sprint with an opportunity. Do they play it safe as verizon and cingular certainly will or do they take a chance.
Sprint is in a unique position because one of the terms of the merger was that sprint-nextel must do something with ...
Watch out WiMAX - UMTS
Well Qualcomm confirmed a lack of a roadmap beyond EV-DO and in the process they sent out some warning signals to wimax - umts.
The days of BS are over boys. WiMAX is years (like 3-5) from being mobile if it ever does become mobile and UMTS really dropped the ball on data. WCDMA is a poor data tech and HSDPA is only a little less bad.
Q now has a commercial ready fully mobile OFDMA that works and well (i ...
Regime Change?
Now was Jorma really that bad? I don't think so. The new ceo is going to face an onslaught of asia (korean/chinese) phone makers, VC funded start ups, and possibly PC makers.
Nokia has made is money by offering low cost, attractive phones, with a nice gui and decent software. The new competitors will not be inept as ericsson, siemens, motorola, alcatel and other were for a long time. Operators also appear to be open to working with a wider ...
Re: This company has an even better chip...
Thank you for posting that. The article you linked to is about SDR (software defined radio). IT is really servers a different purpose. Magnolia's technology (though maybe not the chip because it is frequency specific) could be employed with this.
Will Buy that Phone
Magnolia has a unique uplink technology which basically screws with the phase of the signal to get your call back to the base station.
When you combine that with a diversity receive tech from either magnolia or qualcomm you are talking about getting several db more of gain and hence far fewer drop calls. That is my next phone. Diversity receive will use two antennas to sample the air space in two different physical areas (say the top of ...
Does not mean much
Sprint has tested or observed systems from IP Wireless, cisco, Flarion, Iospan Wireless, and others prior to this test with motorola.
This is just one more test. It is also worth noting that they are testing a pre 802.16e specification. That is kind of important because the 802.16e standard is not even done. It is a very very early test.
Re: it doesn't have to be this way
I guess i am not the only one who is baffled by the current state of US cdma phones. I guess this boils down to Sprint and Verizon. They need someone who'll choose more attractive phones or just repackage the korean/japanese phones with a new RF front end. I'd be happy with that.
CDMA Phones are boring
I hope RAZR can bring some life to the otherwise boring/stale US CDMA phone market.
GSM phones are a lot more interesting as are cdma phones in Japan and korea.
Re: Isn't the Goal?...
BetterThanJake said:
Isn't the goal of the VoIP not to supplant wireless, but to complement it?
Supposedly what companies are working towards is a phone that, when you're out and about, uses the usual cellular networks; but when you're at home, will 'roam' onto your local network and use your broadband connection to make ultra-cheap VoIP calls. A sort of 'fixed mobile' hybrid. Advantage: still mobile, but calls at home are incredibly cheap
At least, that's where I keep hearing we're going. ...
Re: Are wireless companies in trouble?
Echternacht said:
If VoIP catches on, and it will, how much trouble would wireless companies be?
Mobile carriers are only in trouble when you can start receiving a wifi signal everywhere and wifi billing issues are resolved.
Since Wifi has output power restrictions and operates in unlicensed spectrum which has plenty of interference, that is not happening anytime soon. The unlicensed and interference issues also end up meaning small cells which means lots of handoffs between cells and hence poor efficiency/quality ...

RUFF1415 said:
Okay, is it just me or does anybody else out there feel like it's getting to the point where these ultra high speeds aren't going to matter? Honestly, can anybody name something that I would need 100 mbps down for?
Its not just you. You don't need 100 mbps for anything mobile. Those high speeds are ultimately about triple play mobile/fixed service. Operators want to replace fixed voice and broadband (dsl cable) lines as well as providing mobile ...
WiMAX when pigs fly
mikey is singing the intel wimax song but wimax is not going to be in laptops anytime soon and possibly never.
Nokia Grows Up
NOkia and ericsson's childish fighting with qualcomm has screwed nokia and ericsson more than anyone else. Its one of the reasons (though there are many) why wcdma is soooooo late.
Nokia, ericsson and the rest of the GSM gang routinely charge 10-20% royalties on GSM products to the non-gang, which is the koreans and japanese amongst others. Their licensing is FAR worse than that of qualcomm who usually charges around 5% for royalties. You will never here that in ...
