attws will not have sufficient network resourses to offer unlimited data for a long time, they will have to switch to a more advanced air interface.

My antenna is smaller than yours
Both sprint and Verizon (as well as nextel) offer unlimited, all you can use packet data plans using PC cards (sierra aircard 550 and 555 for sprint and vz as well as motorola i1100 for nextel).
These are really very useful and I've been pleased with the VZ card. However, the VZ coverage is spotty in some places while the AWE coverage is very good. Are there any plans from AWE to offer a similar data plan to vz and spcs?

i never understood whythey could not afford it...they can afford me making 6 way calling to 6 different states to hold family meetings but not a simple circuit data connection to get me on the net.....bummers

it's probably not an issue of whether they can afford the $$$ to give unlimited access. it's more of whether they can afford the added traffic that users would put on their new network. give it some time for their network to mature. sprint and verizon have had a long history behind them so i'm sure they have an easier time getting by with these unlimited data plans. also, if i recall correctly from my wireless comm classes, the capacity due to the modulation scheme used in cdma systems is inherently greater than that of tdma based systems like gsm and the "tdma" that carriers like at&t use.

I don't see how they can afford to offer unlimited voice but not data. The data is packets and unless you're transmitting on the air, the channel should be free. Also, I doubt that AWE is smaller than Verizon or Sprint, both of whom offer 99/mo all you can use data.Originally posted by ImmerStark

I don't see either. People forget that there's something hooked into the other side of the antenna. A T1 line carries 24 voice channels, or 1.5 mbits/sec of data. Considering GPRS is probably at most 50 kbits/sec, and is actually tranferring data probably around 10% of the time... there's no problem. A single voice call is 64 kbits/sec throughout the entire duration of the call. Over the air, voice is 12 kbits/sec, but you can see the same packet switching considerations apply.Originally posted by vgill

CDMA does have a more advanced air interface, but nothing spectacular over GSM.

without going too technical into this, the short answer is...
it's not that simple to say voice takes up xx-kb/s bandwidth over the air. You have to understand, GSM is a TDMA based technology and there's a whole lot of resource sharing in time that goes into transmitting packets, whether it is voice or data. ATT doesn't have very many cell sites for their GSM service, so that means limited channels to accomodate voice and data traffic. this is not an issue of data traffic on the backbone, but rather in the air. because people care more about their voice traffic than internet traffic, AT&T is better off utilizing whatever bandwidth they have to give priority to voice customers over their data ones.

so are you saying that me nailing up a voice call 24x7 and playing christmas carols over the speakerphone for a month takes up less resources than me doing some data transfers?Originally posted by Cheese1688

no..i didn't claim that voice traffic amounts to less than data. what i am saying is that if everybody had unlimited data to use with their phones, usage would hike up. at&t probably does not have a good grasp on the data usage patters of its customers to say "ok let's offer unlimited data service and see what happens". they can't afford to test whether or not their network can handle it.

In that case, then ATT should start off by offering unlimited data at the same price as their voice - $100/mo. See how that goes and either raise or lower the price till their economics work out. Maybe if their economics work out at $1000/mo for unlimited data and there are no adopters, they can drop the plan.Originally posted by Cheese1688

The best thing about CDMA is that voice and data do not share spectrum. CDMA is much more efficient, like twelve or more calls utilizing the same spectrum over about 7 for GSM. That is why Sprint and Verizon have unlimited plans and no GSM carrier offers the same.CDMA does have a more advanced air interface, but nothing spectacular over GSM. [/B]

Actually, CDMA does share spectrum between voice and data, which is why its more efficient than GSM. GPRS/EDGE requires a dedicated channel. CDMA has its own capacity problems too, and I'm not going to open that can of worms. However, note that AFAIK, Verizon doesn't have a low-cost traffic metered data solution intended to be added on to voice, like Sprint and the GSM carriers do.Originally posted by davegtestr

Cheese1688, usage would hike up, but so would the amount of money they're charging. Consider the fact that GPRS is much cheaper than circuit switched data (see European carriers) and therefore represents total savings in network traffic. In current GPRS networks, the data channel capacity is fixed. All users fight over it, unlike CDMA where bandwidth is "dynamically" allocated (within limits). Therefore, kicking off voice users isn't an issue unless they make it one.
