Qualcomm Suspends EV-DV Development
EV-DV killed by DO
The real story here is that operators want a full IP network and an air interface with low latency to do VoIP.
The other story is the fact that Qualcomm has reduced the latency on EV-DO enough so people think VoIP over EV-DO might be doable in the not so distant future.
I beleive latency on the latest EV-DO release (the one sprint will deploy) is sub 100 ms. That is huge compared to the 300 to 500 ms it is with 1xrtt and its going to get better.
hope that helps.
It's the time it takes between when the sender first starts sending and the recipient first starts receiving.
Latency is distinct from data rate, which is how much data the connection can transmit per second once it gets going.
So data rate is measured from the moment the recipient receives the first bit. Latency is the amount of time before that.
So yes, in a simple system, latency is the amount of time it takes a single bit of information to be transmitted from one end to the other. Just note that we're talking about a single bit; latency has nothing to do with how many bits you can transmit in a given period of time (which is what most people would consider "speed").
To continue what I was saying before and explain a bit more:
Latency and rate are the two main types of "speed" you can have with a data connection. Latency is basically how long it takes to get started, and rate is h...

Rich Brome said:Actually, what he said was "latency is like how long does something transmit", when in fact it should have been along the lines of: In general, the period of time that one component in a system is spinning its wheels waiting for another component. Latency, therefore, is wasted time.
No, he was pretty close. "how long it takes to transmit" can be another perfectly valid way of talking about it.

Rich puts you in your place and you still dont get it... What an egomaniacal windbag you are, I hope you get a job soon that totally restricts internet access.
P.S. I don't post from work. Only on breaks and while at home. Take a walk on a short pier.
Big Daddy said:That's lovely, sweetheart. Unfortunately, some of us do work. What's with the flagrant language?
You know when I post? Whenever the ***k I want...
seems to me that he is a he/she.

big daddy, you should run. i still havnt established muchdrama's gender. have you?

🤣
nextel18 said:And if I was? So what? Leave it to you to make cracks about something as serious as that. You see...making jokes about transsexuals isn't funny to me. You lower yourself by even bringing it up.
no just you. and are you hinting something?
nextel18 said:That's it. Keep it up. Discrimination is fun, right? Trying to make it three sites, huh?
yes we found your identity or lack there of!!!
dont cry now please.
nextel18 said:You're the one who questioned my gender by taking part in crude jokes about transsexuals. I'm not harrassing you. I'm putting you in your place.
discrimiation, what are you talking about? i wasnt making fun of your gender i was just trying to establish it. stop pushing it already. i have told you many times to stop harrasing me, and you havnt. so just stop.
sure you are. you are not doing anything to me or for me. and yes you have been harrasing me. i am telling you to stop talking to me and you dont that is harrasment.
now, please stop.
nextel18 said:You do realize you keep responding to my posts, right? That's called stupidity.
"I'm putting you in your place"

now, please stop.
nextel18 said:Want me to use little words so you can understand? YOU keep saying I'M harrassing YOU. But YOU keep responding to MY posts. Get it now, Einstein?
how is that called stupidity? when i respond to your posts thats stupidity? hmm didnt know that. are you calling your posts stupid?
he should be ashamed of himself by arguing with the person who established this site and knows a lot more then he knows...
shame on him!
nextel18 said:I didn't argue with Rich. I never argue with Rich. I just gave a definition of latency that I feel is much more accurate. Shame is for the weak.
i know.. isnt it quite pathetic. i try, and rich corrects me in some areas, while i am right, he just explained it better. much gets on my bum and harrasses me sayin i am wrong then rich says i am "pretty close" then he goes arguing with him..

lol i know im a little late.. but that was funny as hell
But here is the real question folks: What comes next?
Qualcomm will obviously tweak EV-DO to improve performance for a few years but then what? I can see only three possibilities and only two make sense.
They could combine channels and effectively become like WCDMA and that is the idea behind 3X, combining three channels. I doubt that is really an option that the carriers are interested in.
Option two is intelligent antennas like MIMO (multiple in multiple out). Every air interface is going that route and BLAST from lucent has been tested with cdma.

isnt the new EDGE tecnology making its way into the circle? shouldnt that be making things run a lil bit smoother 😕 btw...if anyone knows a good site that explains phone technologies can you tell me.
Im pretty good with features but technological terms get me sometimes
I suppose... you'd just have to ask him. 🙂

i am sure he wants to help becuase he helps everyone he can.
I know I know, I'm just bein' a thorn 🤣
how can one be a hero, a psycho, and a dreamer?
The easiest way it could be explained...
Hero: What one wants to be.
Psycho: What one really is.
Dreamer: What one will end up being.
All in all, its someone wanting to be something but never achieving that and as being seen as something else by everyone around him, in the end wasting his whole life being a dreamer, dreaming of being something he never could be or never set out to become. Live's lyrics are very ponderous, I love them.

alright buddy. stop harrasing me. and i am dead wrong? hahah atleast i try to ask. all i see for you is that you keep complaining and harrasing others. try to contribute whether your answers are wrong or not. atleast try and rich or whoever will correct you.

nextel18 said:What? You didn't see the superior definition of latency I gave in that last post?
so why didnt you contribute, instead of bugging me?
but there are also quite a few that disagree and think that it should be defined as something closer to what nextel18 said.Nextel's definition of how latency works is a pretty poor one. See my definition for a much better idea of how latency works.

lol you two are funny.. think Nextel has the croud and judges behind him, but muchdrama has the heart and wil to win... looking foward to the next battle boys 😁

yea, it is kind of fun actually. seeing he/she cry a lot. i think he/she is taking it very seriously, while i am just laughing it up.
HAHAHAHAHHAHAH WOW!!!
"why the persistent jokes about my possible gender?"
why the constant harrassment by you and the continuing of your bashing? why dont you ever contribute? why do you always bash me?

I bash you because you're irritating. In the extreme. Oh, and it might have to do with the fact that your posts are ALWAYS inaccurate.
