3GPP2 Approves CDMA 1x Advanced Standard

Today the 3rd Generation Partnership Project 2 approved a set of standards for CDMA 1x Advanced. The software/channel card upgrade uses interference cancellation and radio link enhancements to increase voice capacity on CDMA 1x networks. According to the CDMA Development Group, the technology improvements (base transceiver station interference cancellation, improved power control, early frame termination, and smart blanking) can be rolled out all at once or deployed in phases across a network. In theory, 1x Advanced can quadruple the voice capacity of a wireless network using the same 1.25MHz of spectrum. The technology will be available in the second half of 2010. Additionally, an upgrade for devices, called 1X Voice and EVDO Data (SVDO), will allow phones to access EVDO data while on a 1x-based voice call. This will let end users send emails or surf the web while on a phone call.

This is already available since 2007

Why wait until 2010 to have the ability to talk and text and send and receive email at the same time when it has been available for a while now. LOL Drooling Razz at&t anyone..
It has been available on At&t mayby wich is a GSM based network. This is for CDMA! This is a rather large improvement most noteably where smart phones are concerned. Every try to use GPS while on a phone call? Doesn't work so hot.
Because cdma was an either or system. If this works well they can retire gsm for good. No more interference with other devices! Yay!
Yes, for WCDMA. Now that capability can come to CDMA networks. The competitive marketplace is a good thing. Smile

why bother?? too late!

y SPEND MONEY to upgrade 1x advance, when you can just upgrade to LTE. it' makes no sense!

if you going to get a new car, get a new car!
y waste your money fixing your old car and get new car next year? makes no sense!
probably just a software upgrade, and not very expensive
It is a bit late, yes, but better late then never.

It will be quite a while before LTE phones are remotely common; perhaps longer than many people realize. And for Sprint... God knows when they'll have 4G phones. They doesn't seem to be coming all ...
