I am interested in how this affects capacity. It's awesome that they are turning it on, and everyone is giddy about the data speeds, but what is the deal with voice? More channels? HSDPA shares voice/data channels where 1xRTT and 1xEV-DO keeps them separate, right? (Until 1xEV-DO Rev A anyway)]]>Dec 19th 2005 12:55AMhttp://www.engadget.com/2005/10/19/cingular-lights-up-two-hsdpa-markets/http://www.engadget.com/2005/10/19/cingular-lights-up-two-hsdpa-markets/Dec 19th 2005 12:55AMhttp://www.engadget.com/2005/10/19/cingular-lights-up-two-hsdpa-markets/http://www.engadget.com/2005/10/19/cingular-lights-up-two-hsdpa-markets/How much does Cingular charge you guys for unlimited EDGE?!? I had it for $25 bucks but got an un-smart phone (W800) so I went back to the 4 meg. Should I just keep it until I get my next 3G phone?]]>Dec 19th 2005 12:55AMhttp://www.engadget.com/2005/10/19/cingular-lights-up-two-hsdpa-markets/http://www.engadget.com/2005/10/19/cingular-lights-up-two-hsdpa-markets/Dec 19th 2005 12:55AMhttp://www.engadget.com/2005/10/19/cingular-lights-up-two-hsdpa-markets/http://www.engadget.com/2005/10/19/cingular-lights-up-two-hsdpa-markets/Dec 19th 2005 12:55AMhttp://www.engadget.com/2005/10/19/cingular-lights-up-two-hsdpa-markets/http://www.engadget.com/2005/10/19/cingular-lights-up-two-hsdpa-markets/
So technically, I got the $40 plan for $24.99 bc i'm an old AT&T customer.]]>Dec 19th 2005 12:55AMhttp://www.engadget.com/2005/10/19/cingular-lights-up-two-hsdpa-markets/http://www.engadget.com/2005/10/19/cingular-lights-up-two-hsdpa-markets/Dec 19th 2005 12:55AMhttp://www.engadget.com/2005/10/19/cingular-lights-up-two-hsdpa-markets/http://www.engadget.com/2005/10/19/cingular-lights-up-two-hsdpa-markets/
#3 - EV-DO always has seperate voice and Data channels no matter what revision you are talking about.]]>Dec 19th 2005 12:55AMhttp://www.engadget.com/2005/10/19/cingular-lights-up-two-hsdpa-markets/http://www.engadget.com/2005/10/19/cingular-lights-up-two-hsdpa-markets/
From Seattle times:

"Yesterday, however, network equipment vendors issued releases that Cingular's new networks were up and running in Seattle and Phoenix using Lucent Technologies and in the Dallas/Fort Worth area using Ericsson equipment."]]>Dec 19th 2005 12:55AMhttp://www.engadget.com/2005/10/19/cingular-lights-up-two-hsdpa-markets/http://www.engadget.com/2005/10/19/cingular-lights-up-two-hsdpa-markets/- Tacoma

SWEET. NOW BRING ON THE VIDEO PHONES!]]>Dec 19th 2005 12:55AMhttp://www.engadget.com/2005/10/19/cingular-lights-up-two-hsdpa-markets/http://www.engadget.com/2005/10/19/cingular-lights-up-two-hsdpa-markets/Will need Cingular to couple it with a good PDA phone but it's not like Verizon has anything to offer me in the PDA phone department either.

But hell i'm a "nay-sayer" and i still don't believe them so NAY! NAY! NAY!]]>Dec 19th 2005 12:55AMhttp://www.engadget.com/2005/10/19/cingular-lights-up-two-hsdpa-markets/http://www.engadget.com/2005/10/19/cingular-lights-up-two-hsdpa-markets/Dec 19th 2005 12:55AMhttp://www.engadget.com/2005/10/19/cingular-lights-up-two-hsdpa-markets/http://www.engadget.com/2005/10/19/cingular-lights-up-two-hsdpa-markets/
Where GPRS/EDGE had dedicated channels for voice and data, UMTS has no barriers. The burst nature of net traffic allows voice data to take advantage of the extra room... meaning greater call capacity. UMTS alone allows for about three times the call capacity of it's older brothers. In addition it allows for flexibility in the amount of dedicated bandwidth to the specific nature of the traffic. Ie. Voice would have a set amount of bandwidth, webpage browsing could have a narrow band with burstability, and video streaming could have a broader band with burstability (more action, higher fps, a big burst of data).

Because HSDPA builds on the data capacity of UMTS it inherently allows for more calls. Furthermore the transition to CDMA over TDMA removes the physically implemented barrier of time slots.

You can conceptualise TDMA as someone chatting on a PC with multiple people at the same time with one keyboard.. giving each chat only enough time to send/recieve a message and then moving on to the next in a continuous cycle.. it appears on the other end that they are talking to multiple simultaneously but in reality they are not.

CDMA is the same scenario, only the person has multiple monitors, multiple arms and multiple keyboards.. and they actually are carrying different conversations on at exactly the same time.

CDMA leaves only the physical limitation of RF; as we have witnessed in the PC world, you can always make computers go faster.

They told me I would be able to continue making and receiving calls with the phone, seems they were wrong. I have yet to make a single successful call as the phone reboots when I place a call and it switches from 3G to 2.5G before the call can terminate to the number dialed. Ditto when I call it from a land line.

This truly is the worst fiasco I've heard of in cellular history. The network is turning this thing into a coffee warmer! And rapidly discharging the battery in 30 minutes can't be good for the battery either.

I'll take my 2nd A845 to work with me tomorrow but I suspect it will mimic its brothers bad behavior (ie this phone didn't develop a failure mode whilst asleep for two months.)

On the upside, I'm getting more bars on the 3G network than I got before. But that could also just be a symptom of the phone's spastic 3G/2.5G yoyo-ing.

Hopefully they will make good on the new phones soon.

Cingular is shooting for an average of 400-700kbps for UMTS and upto 1.8mbps for HSDPA.

Major markets will be lit throughout the end of the year and most should be live by early 2006.

Pricing points will remain the same (at least for now) for data card access at 59.99 unlimited with a qualifying voice line/plan through the promotional period ending in december. Then back to 79.99. Pricing should remain the same for PDA's and regular handsets at 44.95 and 19.99 respectively.

Note to Motorola 3G Victim:
The A845 was certified only for AT%T's UMTS network when it was launched a year ago. If you order one now through the business channel you will still be activated on the legacy at&t network. There are currently no announced handsets certified to work coherently with the Cingular UMTS network. -- This could be why your experiencing problems.]]>Dec 19th 2005 12:55AM
