[quote=AN]CDMA ENG, I thought you were trying to say in your previous post that the carrier would try and limit the bandwidth you can consume:
[quote=CDMA ENG]The carriers will only give you enough to keep you somewhat happy. Devices will be regulated in the future, in my humble opinion, to limit thier bandwidth.[/quote]
Sorry if I miss understood you. So, are you trying saying that carriers are physically incapable of providing bandwidth at a reasonable price?[/quote]
Currently… Yes.
And of course your defintion of bandwidth at a reasonable price is open to interpurtation.
I think the biggest evidience I have towards this idea is the fact that ATT and RIM have both brougth this up.
Sitting on someones desk at RIM is a paper I authored about a year ago simply chornicalling how the device works within network. The device is a capacity HOG. Not in the fact that its demands are great but in terms of how many time it hits the network and due to the fact it is a very popular/numerous device. Carriers handset test groups were not thinking about this before they approved these devices. If it worked to a certian standard as a phone fine… release to the public… But now carriers are waking up to this.
This paper got me calls from VPs of the company… Didn’t get me a raise or anything worthwhile though… 🙁
In actuality your CDMA based PDA is not a phone. It is a data device that dive down to the voice network every once in a while to behave like a phone.
UMTS is doing both at the same time but it is primarily a data device behaving like a phone as well.
Here is the thing… Everyone wants to talk about how fast the air interface is… ATT claims the fastest… which is true… But who cares! If I am providing backhaul to the BTS for data using 2-T1s then all I can get per user is max is like roughly 3 Mbps down. It all depends on the amount of T1s a carrier is willing to put at a site. And I guarntee right now that is only what the carriers are doing.
It all about the backhaul cost…
I am not as good with UMTS as CDMA but I am sure the rates are comperable. I have seen some drive test data that seems to indicate this.
Now UTMS shares a common channel with voice so they may have more T1s at a site then what I mentioned. But I know Verizon and Sprint with thier DO data channel at best can only untilize 2 T1s per channel and in low use areas only 1 T1.
T1s are expensive and account for a major part of the OPEX. Plus many of these T1s go cold after 5 PM. Carriers simply do not want to spend the money to provide some guy in downtown mopping the floors at 9 PM with 5 Megs of data service.
It is simply cost prohibitive.
Carriers will not provide fantastic speeds until the OPEX of backhual is greatly reduced… and this will take some time…
I know this is a bit of a ramble…
I simply am not a great writer…
Hope you found this of some use.
FLU and AN feel free to PM me and I could share some details that I can’t in open forum.
