Casio G'zOne Coming to Verizon
I dont like this.. becuase....
casio's are not very good in my view, but more importantly is that it has 1xrtt. why dont they just put ev-do on it and slowly get rid of 1xrtt?
...
ehh, it's been good in Japan, maybe it will be here. EVDO isn't set up to make voice calls, and since vzw is wanting to use EV for data only I don't think they will.. who knows tho. Kinda a funky lookin phone, but will be good for people who spends lots of time outdoors in all elements eh?
...
well ev-do can do voice calls, but it is under REV A, not REV O that verizon is currently rolling out..
well i would think it is time to do away with the 1xrtt or have a handoff between 1xrtt and ev-do areas. (kinda what they have now. if there is no ev-do it would go to 1xrtt but if there is ev-do then no need to go to 1xrtt)
perhaps Rich can help us to answer this question.
its an interesting looking phone...

EV-DO cannot do circuit-switched voice. Period.
EV-DO rA improves latency and adds QoS that makes carrier-grade VoIP possible, and Qualcomm is paving the way for everything to migrate that way.
BUT that is still years away. We'll find out more at CTIA, but my current understanding is that voice over EV-DO rA won't roll out until well after the initial EV-DO rA launches for data.

thanks for the clarification..
from sources REV A will be on either sprint's or verizon's network starting on 1st quarter of 2007.
thanks again Rich.. as usual. 🙂

I know my aircard will hand off from EV to 1X and viceversa with no problems. So im sure they can make phones do it too.
...
exactly.
that is what i thought that they could do with phones becuase they do that with the pc-cards. (i have the powervision ev-do card also)

did you read??
EVDO works for data only right now. Hence your DATA air card can switch between the two services.
Voice will not work on evdo, but in the near future we will have phones run on both EVDO and 1xrt. But the EVDO network isn't there yet.

Current EVDO phones (and data cards) do that. If they didn't, you wouldn't be able to talk on them, or use them for data in non-EVDO areas.
... But the EVDO network isn't there yet.
It's there, it just needs upgrades for rev. A and VoIP before it can support voice.
...
what do you think of REV B? we will probably see it in the 2008 or 2009 time frame.
do you think the carriers who are going to REV A will go to REV B? is it an easy upgrade? (software primarly?)
thanhks.

No clue. Honestly I haven't had much time to look into B. I don't think it's all finalized yet, so it's a bit early to talk about deployment. I'm sure it will come up at CTIA, so I'm looking forward to learning more then.
...
oh ok.. it said that in reports that it is actually finilized. it will also be published this 1st quarter.. (jan feb march) so i guess less the a month.
REV B looks like it will probably be going against Wimax on speed.
according to reports it is mentioned that REV B will be up to 73.5 mb/s on the FL and 27mbps on the RL on 20mhz, 1.25mhz would give 4.9mb/s and 5mhz would do 14.7mpbs.
should be interesting of what qualcomm and others will tell us about this interesting technology.
how do you think it would scale up against WIMAX?

very rude, and you didnt have to be with that "did you read" comment..
i know that ev-do rev o works is for data only and rev A has voip.
the whole conversation with barryefau was about whether it will handoff from 1xrtt to evdo and vice versa.. that was the main thing, and obviously the answer to that question was that yes it would..
this was when rich by accidently didnt put ev-do under this phone and put 1xrtt instead... obviously since he corrected it, it became a non issue.

Technically, I didn't say the U.S. version isn't EV-DO, just that the Japanese one is 1xRTT.
There are hints in the FCC docs that the U.S. version will have EV-DO, but the hints are in places that are historically unreliable, so I'm not comfortable saying for sure that our version will have it.

ahh i see. i actually found something on the FCC site under url;

"Inquiry:
I am currently reviewing a phone with EV-DO capability (CDMA 1xEV-DO 800MHz), and so I am
contacting the FCC to seek guidance on the review. I would like to point out that it is unlikely that any
SAR would be applicable to EV-DO operation- as a data only service (unlike full-fledged cdma2000,
there is no voice option here), it is used for emails, browsing the internet, etc., which would require that
the phone he held in the hands for normal operation (thus, a mobile configuration, not portable). If used

You're right. It definitely has EV-DO (Duh... right in front of me - don't know how I missed that!) 😉
I updated the news text.
Thanks! 🙂

bottom line for us non tech people if purchased in japan could this work now here in the stated?
...
idealy yes, it should becuase both carriers, KDDI in japan and Verizon in USA uses cdma (evdo), but i dont think so becuase they will probably have to tweak something before it will be used by verizon.. i also am understanding that KDDI is using cdma ev-do on 800mhz and that is the same that verizon wireless uses. (Rich would probably know more about this..)
hope that sort of helps...

Although I'm pretty sure KDDI does use the same band, unfortunately the darn Japanese had to be different and switch the forward and reverse link bands. In other words, KDDI phones broadcast on the band that towers broadcast on here, and vice-versa. That makes it 100% incompatible. It might as well be a totally different band.
...
yes, KDDI uses the same exact band that Verizon wireless uses in the 800mhz band for ev-do. (they announced this during their presentations and press releases.)
wow, i didnt know that about our japanease counterparts.. shame on them.. but i guess since their technology is so more advanced then we are, they might as well classify it as a differnt band and technology all together, even though, they use the same exact technology.
cant they just take that same phone or idea and looks and have it be adjusted to be used on verizon's band?

Well, that's basically what they're doing with this Casio phone.
It's relatively easy for a manufacturer to take a phone for KDDI and swap out just the RF circuits and antenna to make it work here. That's one reason Sanyo has been so successful with its phones for Sprint. Many of its Sprint models are based 95% on Japanese models.
But it is a hardware change, so you can't take an actual Japanese phone and make it work here.

yes, i agree sanyo has been very successful..
the person who i was talking to about the whole situation asked the question in a vague way becuase it can work here, but as you and i both know, it has to be tweaked to be able to use the USA's networks. (cdma of course)
i mean it makes a lot of sense that a carrier there using the same exact everything should be able to use it here in the states.. i actually didnt think any tweaking would be needed since they use the same everything, however, i didnt know about they use differnt hardware then we do until you told me.
interesting. thanks. i hope he got the answer he was looking for.

Absolutely not. Different frequency bands. Won't work.
The Korean version might if it's CDMA 800 - I'm not sure. But the problem with using Korean phones here is that most of the features (all the cool ones) won't work here - just basic voice.
