What the future of Wireless is shaping up to be!!

Nortel Networks Ltd. said it has reached what it described as a milestone in a demonstration of OFDM and MIMO technologies, with speeds that transcend current third-generation capabilities.
The company said the combined technologies can support twice as many subscribers as OFDM alone, adding it is "proposing OFDM/MIMO as its evolution vision beyond HSDPA/HSUPA and CDMA 1x EV-DO into 3GPP and 3GPP2 wireless standards."

OFDM is the base radio technology used by Wi-Fi and WiMAX, while MIMO is an advanced antenna and space-time processing technology, explained Nortel.

This would rock!!! I'm sure that it would be the next path after EV DO RevA as long as Data services become profitable. Hopefully Verizon does this and is the first so all of the Cingular dweebs talking HSDPA smack will shut up. I use an EV DO lap top card and have seen speeds over 2.4 megabits already here in Chicago and that is pretty quick but this would be 37 megabits!!
That's going to be insane 37 megabits. Data hopefully will be getting used a lot more as EVDO becomes available across the VZW map. VZW needs to step up their advertising though I have only seen one commercial for the V cast or our broadband access

I don't watch much tv but have seen quite a few in Chicago on channel 2 if I remember correctly. My Bro works for VZW in Network Engineering and said that they are launching it in more areas soon but wouldn't be specific. I think that they need to run it on the PCS spectrum they own so there might be areas where they don't have PCS spectrum and won't have EV DO anytime soon. I have used it in Madison, Milwaukee and Chicago and it is pretty good so hopefully it will take off soon.
Yeah I'm in San Diego (Poway) and I have used the aircard and the vx8000. Good stuff V cast definalty made the day go by faster
bigdaddyjay said:
How is V cast?? I'm old school and use a moto T730 but would like to get a new phone soon and V Cast wouldn't be bad in Airports or traffic situations.
The quality is VERY good. I have a friend that has Cingular's Mobi-tv (I think thats whay they call it) and it is really bad. They have the stand up comic section good stuff very funny. I have not tried the 3d games though.

I am overdue for a new phone, what one is best so far (EV DO Handsets). I haven't seen anyone around here with one yet to check it out but I'll have to go to the store or see if my Brother can get his hands on one to bring over.
The 8000 by far. It a great phone. It is true it's a little bigger but that does not bother me. The Samsung is ok but the only one I would by is the 8000. It has really good picture and video quality not as choppy as on other phones
bigdaddyjay said:
The size doesn't bother me, small phones are usually flimsy (Moto V3RAZR) My wife uses an LG 6000 and she also wants a new phone and her LG has been great. The only issue I have is that my Dad lives in an Alltel area in northern Arkansas and the Digital doesn't always pick up there and I'm there 4 or 5 times a year and my Moto definately is more reliable than the LG. There aren't any EV DO with analog right?
No they are all digital right now.
Anyway, the RAZR isn't a small phone. It's a thin phone.

hey do you think its worth the 15 bucks per month?
As of right now, no. AS soon as the content gets larger I do believe I would pay for it. As a promo you get the first TWO months for free soo It's worth trying out especially for free. Plus if you get the $15 add on it does not use your mins to access VCast
thats obvious. it shouldnt charge your mins and those carriers who do are very pathetic.
i do not think its worth the 15 bucks per month, becuase as you said not a lot of content plus its over the DO network (rEV O) which isnt fast with booth speeds and latency. i guess if they upgrade to REV A, which they dont even have an option for then it should be a lot better.
my opinion is this; i belive that verizon will get hurt for their high pricing for push to talk, ev-do, and vcast becuase they arent worth the money that they are asking for. i think they are just trying to lure in anyone becuase there is no other comparible high speed data to them. they want t...

i mean the first push to talk was so terrible i wanted to laugh to be honest. i thought it was going to be good becuase of the cdma network and cdma is a lot better with coverage/capacity then iden. however, i learned after they launched it that they were rolling it over VOIP and thats why it was so slow. so they spent probably hundreds of millions dollars on towers and phones and it was a piece of junk. if i recall correctly, combine sprint and verizon had 500,000 subs on the push to talk network then. pretty pathetic to be honest. (same with sprint with being pathetic etc..)

"It is going to be interesting to see the qchat finally come out. " i cant wait till QCHAT comes out!! 1.5 seconds latency and thats just as of right now, and they have till 2007-2008 to prefect it. even if verizon deploys ev-do rev a and re-deploys push to talk, qchat will destroy them especially with latency and with the solutions that sprint/nextel can roll out. we know that nextel/sprint will have a better network then verizon in every way...

yea, the version is a lot better but is it better then sprint's version and nextel's? of course not! i belive the latency has gotten better for verizon, but not as good. (i checked in a verizon store as well as i did some channel checks)

look at what they are doing its quite amazing... from ev-do rev o, rev a , umts/hspda, edge, qchat, wcdma and sooo sooo much more. and they are also doing their Tv solution, which should be great.
yea, cdma is a lot better then every other service out there when it comes to high speed, capacity and coverage. thats why a lot of other providers worldwide and domestically are moving to them.

i am re-wording that..... look below for the thing i wanted to say...
"if barry west can do very well with nextel's network now, eventhough that they have a lack of spectrum and capacity nationwide against other carriers, imagine what West can do with their (nextel/sprint) surplus of spectrum"
yes, thats better!! sorry!!

i dont think verizon will do this becuase they need the spectrum to do it, and i dont think they are willing to spend some more money on the spectrum as well as a lot of money on capex increases.
They might (I hope.) I assume they have a lot of money being saved for something since they have not made any huge investments lately other than the Quest deal. This would be a good next step after EVDO Rev.A , but we all know how fast things change with wireless
we shall see though.....
