^How fast is 1xRTT^
Not known. And if it's all hype, not real fast. I'm a little discouraged by the view afforded into 3GPP2 internals linked by Ben Garrett this morning. EV-DV is indeed more than 6-months from submission. To the degree that 1x is hype, though,I think it's counter-hype. GPRS at 150kbps was pushed so hard the marketing guys had to step in and quash the hype because of the mass of supplicants with high speed applications raring to go.
My context of competitive field was that of AWE, not the world. Their attempt at differentiation will be expensive and difficult for the i-mode business model to offset. The GSM overlay will not help their capacity problems (and GPRS/i-mode, if it's used, will exacerbate the problems unless they pour more into 2.5G, not to mention spectrum for 3G and ...)
As for "corporate e-mail" as a "killer app" on GPRS, I'm still absorbing today's links, but my impression is that security is a problem. I've accepted that CDMA is more secure, but have no real documentation. Simon Buckingham and another of your links today point to a GPRS security problem, to the extent of interfering with use by the corporate subscribers in trial systems. Not an insurmountable problem, I'm sure. Just there right now.
In general, I'm amazed at how parallel, or neck and neck the competing systems are running technologically. Fascinating race. Bets should be hedged among infrastructure providers, but I see no long-term losers among the big players, vainglory aside. |
