t's frightening to see the number of people who seem to make investment decisions based on technology and without understanding that technology.
I know I know, before we admit that CDMA2000 is not backward compatible with IS-95, we can't call ourselves knowing anything.
And BTW, it is indeed frightening.
Or maybe the PDSN, the CDMA equivalent of the SGSN/GGSN, will make IS-95 networks obsolete
Showing us your knowledge again? Get this, there're two type s of data in IS-95, packet data and Async data. Packet data will be routed onto internet from BS directly. It doesn't need your funny SGSN/GGSN type of add on. Asyn data is done by dial in.
BTW, IS-95 is reffering to the radio side standard. The landside is called IS-41.
Now educate me how that IS-41 will be obsolete.
I have seen the CDMA-2000 standards and they all seem to assume that voice will always be circuit switched and/or separate from data. Considering the rest of the network (backbone and land-line) is, for better or worse, moving to VoIP, is a little disconcerting to see little more than cursory consideration of this in the CDMA-2000 standards.
Do you even know what is the so called VoIP? Geeze. (hint, tell me what layer it should be in).
Oh, and thanks for the disconcerting. |
