Looks like a couple of Nextel fans-boys. Cingulars PTT has so much more potential then Verizons AND Nextels. Yes... 7 second connect at first... virtually no lag either. Biggest advantages are that Cingular uses their voice network, not the data network that Nextel and Verizon uses. Data isnt always available at EVERY tower like voice is, is Nation wide at no extra cost. Users have alot more options. Nextel will no longer have the PTT monopolized.

maybe you should do some reserch. nextel does not use data for its ptt. nextel is ptt with gsm built in. that is why it always has been and always will be the fastest most reliable ptt out there.

iDEN is a TDMA based technology, but it isn't GSM. With iDEN, PTT is primary and telephone interconnect is an add on, not the other way around which is what all the "other" carriers are attempting to deploy. 😉

dumbfuck.. only 2 major carriers in the US use GSM, Tmobile, and Cingular.

Actually, Nextel is IDEN(PTT) interlaced with TDMA, not GSM

man nextel will always rule tha ptt fa sho

you are somewhat incorrect.|

iDEN is a dual-channel technology, with the voice side using GSM and the walkie-talkie/PTT use a TDMA technology shared with DATA/Internet.

NEXTEL doesn't use it's data network. If you do a search on iDEN and read about it you will learn how it works. Don't go spouting off on something you don't know anything about.

what will be interesting is when they move the entire spectrum to 2.5Ghz in a few years. the effective distance from 800mhz tower is about 10 miles, and from what i heard from a SPRINT engineer, the effective distance on a 2.5 Ghz tower is going to be about 1.5 miles. If S/N's PTT is moved there to get away from the emergency band, then how good will the PTT coverage be then?

They're not. The 2.5GHz spectrum is going to be used strictly for broadband stuff like WiMax. iDen will be supported through at least 2010.

i am not sure why many people are getting confused with the 800, 1.9ghz and 2.5ghz spectrum bands that they have.

"

they arent. they are only going to use this spectrum for 3g-4g data services.

in addition, they arent moving all to the 1.9 either that they got from the fcc.

many people are getting very confused over this...

they are staying with 800 for quite sometime and even on the cdma network as they start to migrate spectrum and towers in 2007.

who in sprint or nextel uses the 800 mhz cdma?

sprint has not owned any 800 mhz since they sold off all of their 800 mhz in 1996

no one uses 800 cdma. nextel uses 800 iden (form of tdma)

They may be aloud to use that freq until 2010 it would be surprising if they did. I would expect sprint to push for their new customers to use ready link. FCC passes huge fines since Nextel over grew that freq.


In my option nextel is a fad. What is the difference if you call or walkie talkie? Mobile to mobile!

verizon, altel and us cellular all use 80 mhz cdma.

nextel will use the iden long after 2010 becuase we have contracts with public safty which are very profitable. includeing a huge one with the department of home land security.

and last but not least why would you use ptt insted of m2m?

The tests that you have seen are on an unloaded system, ramp up the traffic on the network and I bet that the times will not surpass S/N. So far you are comparing apples & oranges. S/N is mature and in operation with the same initial connect and latency times of a Motorola public safety radio system which is about as close to real time as you can get.

Cingular has a lot of work to do courting big business to migrate PTT from S/N to another carrier. The problem is that so many S/N iDEN users have contacts outside of their company structure that they work with, that going with an other carrier will be like going backwards in connectivity and productivity.

It doesn't matter how much traffic there is because the PTT is over voice. The only effect traffic would have on the PTT is if it was over the data network, which it's not.

Actually it does matter. If the voice channels are full the PTT will not work.

That's not what he said though. He stated that the volley times in a PTT call would vary due to traffic. Not true. Either you can connect the call, or you can't. The speed of tranfer of the information will never be diluted.

Agreed, which is why it will be people who adopt fads, and small business who don't really have much need to contact other people outside their company that will get PTT phones first, big business may or may not come later, but Cingular already has all that laid out. Like I said, I don't see us dethroning Nextel anytime soon, but if a good number of smaller suppliers (etc) get with Cingular for our PTT and our coverage, someone from one of those big businesses will be out there and see it, and go "hmm, that is pretty good.. I wonder" and that's all it will take to at least get them thinking about the possibility.. Either way it should be noted that I hate PTT, and I wish the feature would just die and go away from any cellphone company.. but...

now let us not talk abotu sprint ready link. by far better then cing. ready link has 3 sec max latency. gps solutions, faster data, largest total voice coverage.

is that 3 sec every time one person talks or initial connection? Cingulars is NOLY for initial connection, after that the latency is about a half a second.

sprint Ready Link has a 3sec latency for the initial conection then after that it is less then .5 sec

jinx7676 said:

Actually it's only 150ms vs Nextel's 400ms, but whose counting.

Yep...the ears can't hear the difference between 150 or 400ms even if you were standing next to each other.

I would like to see 150ms latency on a storage "o" scope to see if it actually is what they claim. Like all wireless technologies there are outside influences that will make it worse from the laboratory environment as soon as its deployed.

Like all wireless technologies there are outside influences that will make it worse from the laboratory environment as soon as its deployed.

And once again, if you were referring to traffic, that will never affect the latency on Kodiak's platform...ever.

If Cingular has call blockage on the voice side, which they do down here in South Florida, then it will be affected. Don't say that it won't as it sure can....the Kodaik system hasn't been deployed on a mature system that we know of and there is no telling how it will act.

Yeah, as much as I like out PTT system (in comparison to Nextel) I have to agree.. no amount of...

""who knows maybe tmob will launch ptt too that way they can atleast be better then some one!""

T-Mobile is not that stupid to launch PTT...its a waste of time!

a cuz nextel is better iden cuz u can load ring tones and other media like phone book editer and stuff hit me back o and cingular and no other incuding dat wack sprint junk will master ptt direct conect like na na nextel under a second plus nextel sounds better then sprint

wow is it just me or does every one else who reads this hear it in the voice of farmer fran from ther water boy?

I would assume he is talking about Alltel and yes we do use Kodiak. That does sound like Alltel's PTT service.

I don't see it... Cingy doesn't even know how to sell to business clients let alone market PTT to them... It all started way back when, when BSM & SBC created Cingy. They started marketing to the individual (kids, it seemed), I think that alienated a lot of the market. If you didn't go with Nextel for your enterprise, you went with AT&T... Now most of the upset AT&T are moving to VZW....

lol,, yea..like i said in a post before, my friend, she left attws, she didnt want to be a part of cingular, she went VZW. well whatever works for her, i guess?

I'm not misunderstanding anything. 6-7 seconds is the max....from what I've been told AND seen 3-4 seconds is more the norm. And 6-7 seconds is still shorter then it takes to connect a phone call and wait for the person to answer. Either way, this is only ONE negative thing about Cingular's PTT. After that you have all the included extra features plus cingular's MUCH larger network, and when you include all that, I think people might be willing to look past an initial setup time, considering cingular's PTT is argueably FASTER than DC once connected.

Also...this is coming from a person who's current phone is a Motorola i860. When nextel's direct connect works right I love it....but the other half of the time I get errors like "User un...

From my own personal use and experience, it has been AVERAGE 7-8 seconds. I've held both phones next to me and set up 9 or 10 individual sessions and that was the result that I got.

Most business users want no-frills PTT solution that just works. I'm sure Cingular's PTT won't work if the user being contacted is actively transmitting data.

The phones themselves may be nice (I use an LG slider myself, albeit Sprint), but they're in no way able to stand abuse. Contractors will definitely NOT switch.

Maybe it's not to you, but 7 seconds is eternity compared to Nextel's almost instantaneous if all you want is a quick reply. Let me say it again, features don't mean anything if the basics aren't up to par. And the features themselves, alth...

The gov will never use any thing other then nextel. why? because 7 seconds is way to long! if an oficer is being shot at he does not have 7 seconds. and les face it the gov is a huge portion of th eptt market so i know nextel has nothing to worry about.

well said. 🙂
