[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.
I don’t understand this CMDA stuff. This whole internet thing is also weird. Best description I’ve heard is that the internet is like “tubes” with bandwidth sorta like how big the pipe is.
