CDPD will be turned off June 2004. I am currently a CDPD subscriber with AT&T wireless, and I have received this notification.
1xRTT isn't a bad path to go. It bursts up to 144kbps up/down (symmetrical), and provides an average throughput of perhaps 60-80kbps. I see about 100kbps in the Seattle area on sprint, enough to stream a 64kbps mp3 on the freeway with room to spare. 1xRTT will provide 144/307kbps by the end of the year on some carriers and already supported by most current handsets and pcmcia cards -- 1xRTT's supplemental carrier system can support up to a megabit on current hardware. 1xEV-DO (Korea) supports peak rates of 2.4mbps, while 1xEV-DV (which the US will see in a couple years) supports peak rates of 3.09mbps. Good news is that everything is backwards compatible with the original 2G hardware. Things aren't so great on the GSM side of the pond. not that the standards are bad, but backwards compatibility issues between UMTS, EDGE, and GPRS are going to propose some serious issues (your going to have to buy new hardware). >-----Original Message----- >From: Jay R.
